conditioning

One of the most hostile places on the planet is, ironically, our best “air conditioning” against the greenhouse effect

by

We knew that the Southern Ocean It is, in essence, the thermal lung of the Earth that is essential to regulate the temperature of the entire planet. But what we didn’t know exactly was how it managed to process such an amount of energy. Now, science has revealed that storms play a leading role that may be key to facing the global warming. Its usefulness. To put ourselves in context we must know that the Southern Ocean It has the ability to absorb more than 75% of excess heat that is generated by the emissions of greenhouse gases that humans themselves produce. This is something that makes it a true heat sink, potentially becoming the most important in the entire world. In this way, if we remove this Ocean from the equation of current life, the temperature of the atmosphere today would be much higher. A blind spot. The climate models that we use on a daily basis have it, since when trying to predict how water heats up, the calculations did not quite fit with what was happening in reality. Clearly, some type of element was missing here that we did not fully locate. But this has come to an end, thanks to the team led by Marcel du Plessis and Sebastiaan Swart who They have found the missing piece of the puzzle: ocean mixing driven by summer storms. A phenomenon that literally allows the ocean to ‘swallow’ atmospheric heat. How is it possible? The mechanism that this ocean follows is as violent as it is efficient. During the southern summer, the sun heats the surface layer of the ocean, and if the water remains stagnant, then the heat will remain on the surface stored in the water, making it easier for it to return to the atmosphere or accelerate the melting of ice. The correct thing to do in this case would be to literally bury it in the depths. And this is where storms come in, where the intense winds and extreme waves that are produced act like a giant mixer. In this way, the energy of the storm agitates the water, pushing heat from the surface into much deeper layers. Towards the depth. In this way, storms help the surface of the ocean cool, which gives it the ability to continue absorbing heat from the air in a more efficient way. And where does all this energy go? Well literally, When you go down to the deep sea you are ‘trapped’ there for decadesslowing down immediate atmospheric warming. Although we must keep our eyes on what will happen in the future. How it has been measured. This is a practically obligatory question when we talk about the deep sea, which are truly hostile places for anyone. That is why our best ally has been marine robotics. Instead of relying on satellites that have difficulty seeing through clouds or measuring depth accurately, this technology transferred to underwater gliders and autonomous buoys are capable of measuring temperature and salinity in real time. All this while a storm is passing over them, causing the phenomenon that has now been studied. In this way, this technology has given us the ability to monitor the ocean “from within” during events that are impossible to study on ships. We care (a lot). This discovery can be compared to that of a coin with two sides. On the one hand, we already have confirmation that the Southern Ocean is a very powerful ally in the fight against climate change. But on the other hand, we have a very disturbing question: what will happen if storm patterns change due to climate change itself? If the storms move or lose intensity in this area, we could lose this “sponge” of heat that is slowing climate change. The consequences would be quite clear: a large increase in the temperature of the atmosphere that would be felt throughout the planet.

They could not turn off the air conditioning

by

During the last three years, one of the Greater luxury supereyates It has remained tied in the port of Marmaris, on the Turkish coast, before the threat of seizure by the Blocking financial assets Russians for the Ukraine War. He Eclipseowned by Roman Abramovich, not only stands out for its dimensions, but for its impressive consumption. In fact, this has been one of the most controversial points since during the three years it has remained in Puerto they have had to keep the engine running because they could not turn off the air conditioning. The context of Ukraine. After the beginning of the invasion of Ukraine by the Russian army, the United States and Europe imposed a financial block for the assets of the Russian oligarchs. That block left tied to port and seized to hundreds of suspicious superyates to belong to Russian millionaires close to Putin’s power circles. He Eclipse It was one of those yachts that, to avoid being seized like many others, has had to remain in The neutral waters of Türkiye. Forced air conditioning. If you have filled the deposit of your car during this vacation you will have realized the price to which the fuel is. Well, during the time that the EclipseIt has remained tied in the port, has had to keep its engines lit to feed the air conditioning system of the superyate inside. Not that your captain and crew They were hotbut it is a measure to prevent The noble woods and the luxurious finishes of the interiors of the yacht deteriorate because of the humidity and saltpeter of the sea. By keeping the air conditioning onthe interiors are maintained at a constant temperature and humidity. 1,000 liters of fuel per day. Have the air conditioning at home already supposes An important disbursement On the light of the light, so the cost was not going to be less aboard one of the largest and most luxurious yachts in the world. According to estimates, the Eclipse It would have consumed about 1,000 liters of fuel per day only to keep the air conditioning on while moving. Other fixed costs are added to this consumption: keep the Eclipse Mooring involves paying $ 209,000 a year only in cattle rates. It is a usual maneuver. The decision to maintain the air conditioning on It is not an occurrence of the Eclipse captain, but it is a usual maneuver in the superyates, since the cost of fuel tends to be lower than the cost of repair and the inactivity time of the boat. For example, the case of Alpha Nero, the luxury yacht seized on the island of Antigua, which almost leads to ruin to the small Caribbean island because it consumed some 2,000 dollars of fuel daily that were in charge of taxpayers. OK To what is published by The avant -gardefilling the million liters of fuel of the eclipse tanks costs between 1.5 and 2 million dollars. Keeping a mansion is not cheap. He Eclipsewith its 162.5 meters in length and 22 meters of manga, it has two helipuertos, a submarine, a pool that becomes a dance floor and even a Anti -emissile Anti -Didish System. Since its launch in 2010, it has established itself as the second largest private yacht in the world. The estimated value of Eclipse It reaches 600 million dollars, and has an annual maintenance cost that is around 60 million dollars. However, to fuel costs (even being tied to port) of the eclipse, periodic maintenance costs must also be added. According to publishedForbes, in recent days, Abramovich’s superyate has set for the Tuzla shipyard, in the Asian part of Istanbul, to submit it to complete renewal to overcome the special class inspection, A kind of ITV For ships that must pass every five years, with a cost that could exceed 40 million dollars. Only the paint budget for the eclipse already exceeds 20 million dollars … and that left the air conditioning on.

Tricks to use car air conditioning in the most efficient way

by

Summer, 40 degrees in the shade and desire to return home to throw us the deserved nap that we all deserve when we come from taste a paella. The same one that can be indigented if we ride in the car and do not apply some simple tricks to cool the cabin as soon as possible. Here is the difference between cope with the return home or make the car seat a real hell. First of all, be foresee. You cannot always but it is evident that the longer the car passes in the shade, the better it will go later. Keep in mind that if there are extreme temperatures on the street, these are much higher inside our car, overheated without an escape to come out all that hot air. Therefore, before leaving the car to his fate, he tries to leave it under a shadow and, whenever possible, with the parasol placed. The RACC calculates That when the sun makes its own, the interior temperature of the car can rise at up to 20 degrees. Especially in those cars with black upholstery. Then, A parasol helps reduce temperature Interior in up to 11 degrees, what we like to reduce the suffocating heat as soon as possible. Also, small Offtopic, Heat can damage the dashboard materials. The windshield makes of magnifying glass and the temperature that the upper plastics reach can be very high. With a parasol we will reduce the risk of premature wear such as the steering wheel “peel” and lose part of the plastic or break the leather that covers it. The Japanese “trick”. Some time ago what was called as “the Japanese trick” was viral. The truth is that I could carry the word “trick” but The Japanese thing seemed a bit free. Anyway, the case is that it works. If you get to the car and you are burning, it is a good idea to lower the windows and open the doors for a few minutes. Thus the hot air will escape little by little from the inside. To accelerate this process, what we can do is take a couple of doors and “fan” with them the car. Moving them with some momentum we will generate a current of air that will lower the temperature faster. Click on the image to go to the original post “The first thing, go down the windows”. If, on the contrary, you want or need to get the car as soon as possible, Juan José, one of the Ebenezer workshops mechanics that follow more than 300,000 people in Tiktok, more than 300,000 people, recommends That “the first thing, when riding you, is to lower all the windows of the car.” The council follows the same logic that before but is applied in motion, during the first meters, the car in progress generates an air stream that will help the heat escape from the interior and the temperature is reduced as soon as possible. What is recommended is that when we win speed, Let’s keep the driver or passenger window open and the opposite. If we keep all the windows at the same time open or only one of them we generate that annoying noise caused by the displacement of the air inside the car. The air, up or down? It is one of the big doubts. Juan José recommends putting the cold air down, “towards the feet” because “the cold air weighs more and the hot air will tend to climb and go through the windows.” Indeed, Cold air weighs More so it is interesting to put this system into practice as long as we keep the windows of the car open a few meters. In this way, it will help air the interior. Of course, then Juan José talks about climbing the cold air to the roof. Although in the video it is not mentioned, this should be done when we have already closed the windows. The idea is that the air that escapes for them is hot and if we have them open and put the air to the ceiling, it will escape part of that cold air. With them closed, the cold air “falls” to being denser and cools before the air conditioning. Maintenance. Finally, do not forget that all this works as long as we have done adequate maintenance. Before going on a trip, it’s always good take an eye on filters To have them in the best state, which will help us to cool more and breathe a better quality air. Likewise, if the car cools little, it may be due to problems with the load of air conditioning gas. Similarly, it is important to review it before summer because, if you do not, you can find that All workshops are completely full.

“You can pay 150 euros to fix your air conditioning or you can do it yourself”: Scotty Kilmer, mechanic

by

It is the song that returns to your head again and again. That, without any reason, comes to your head early in the morning, while showering. And that does not abandon you for days. And although the situation is more than known, and we know how it works, it does not cease to surprise us. A summer. And another. And another one. The same goes for air conditioning. Summer arrives and the air conditioners break. It is always at the worst moment and, almost always, it is because We have not looked at it well for the rest of the year. Without correct maintenance, car air conditioning cools for spring temperatures but is not enough to a heat wave. It is there when we demand most and, pum, it breaks. The Calvary arrives to look for someone who can repair a system that seems essential to travel on vacation. All this experience is well known by my partner Amparo Babiloni, who has left in writing Everything that has happened to him and how he has had to act. To prevent this from being repeated, the council is simple, short and direct: maintenance. Maintenance that we can do ourselves, which will take some time but that taking the appropriate indications can save us good money in the pocket. Do it yourself That is the message of Scott Kilmen, an American mechanic who with decades of work behind him has a YouTube channel with more than six and a half million followers how we can keep our car in the best possible state, some tricks to avoid and how to act in case of breakdown. In the video you can see in this link, explain what to do if your air conditioning does not cool enough. Something common when we have been making a timely use of it with temperatures softer. Among the tips that Kilmer provides is, in the first place, to replace the air conditioning filter. This filter is recommended to replace each car review but if you do not make it difficult to pass the cabin. Only this small detail will significantly improve the amount of air that arrives and the quality of the same. It is a simple operation And it usually has easy access, so we can change it without much difficulty for a handful of euros (less than 20 euros, generally). In addition, this not only has its advantages in summer, it is also especially useful for Avoid allergies in spring. Then, Kilmer proposes to improve the quality of the air we breathe. It is as simple as using An antibacterial product Since, as he explains, a dark and humid place such as the cooling system of a car has everything so that bacteria and microbes are developed that fall from the air we breathe. Especially if we live in a wet zone. With the air lit at full performance, select the air inlet outside. Now, Kilmer recommends going to the air intake under the hood and spraying it with the antibacterial product to reach all corners of the system. He also recommends throwing it overnight and letting him act without fear until the next day. Finally, if all this has not ended by solve the matter We only have to recharge the air conditioning gas. In that case you have to buy a Compatible with pressure gauge and apply it to the low pressure system. The pressure gauge is important because it will give us an immediate response of system pressure. While it is green, says Kilmer, you can continue adding gas and we must stop if it reaches the red zone. In spite of everything, remember that these are more or less simple tricks that require a minimum of knowledge. Each driver is the one who must value whether or not it is worth investing money in a professional mechanic.

Xiaomi has a plan to conquer all the homes of Spain. And his first step begins today with the air conditioning

by

When Xiaomi He celebrated its fiftyth anniversary two months ago, Lei Jun, CEO of the Company, presented to the world the products with which the company I would conquer the future of consumer technology. During that event there was talk of refrigerators, washing machines, of chipsof electric cars and even smart taps. However, the most striking was what No There was talk: mobile phones. In his fifteen years of history, Xiaomi has been inserted in the popular imaginary as a company of functional mobile phones and good price. The figures are witness: Xiaomi It has grown year after year in Spain until it becomes the indisputable leader in sales, and the perspective in the medium term It remains of growth. It was the company that broke the taboo over Chinese technology and the one that opened the door so that others, later access the western market. That is the past. Xiaomi’s future does not only go through mobile phones. May events and Junewhere they also presented The glasses and The Yu7they symbolize a change that the company has been undertaking for years. The future of consumer technology no longer resides on phones (although they are still very important, such as THE MIX FLIP 2 reveals) but in everything that We can connectwhat today translates into all applications of our daily life: from The appliances even watches, through voice attendees, televisions and, of course, The electric car. Xiaomi aspires to unify all the technologies of a life and shelter them under their brand. And that aspiration is ambitious: FEVER FOR SU7 In China, it shows that there is an appetite of “Xiaomi products” beyond mobile phones even in the most unsuspected places. The one that arrives in Spain today is a wide tour in our country, every year more if we think In the demanding heat waves that all summers attain us: the air-conditioning. The model that Xiaomi launches in Spain (the MIJIA AIR CONDITIONER PRO ECO In two powers, 2.6 kW and 3.5 kW) It is the spearhead of a much more ambitious expansion. In China, Xiaomi has been selling all kinds of household appliances and domestic technologies for years. Spain is its gateway to the western market. And to understand its strategy, to decipher what is the future path of Xiaomi globally and in our country, we have sat down to talk to Borja Gómez CarrilloCountry Manager of Xiaomi Iberia. This is how Xiaomi money earns – they attract you and catch you The air conditioning and Xiaomi plans In your last events you have accent on appliances: washing machine, fridge and even an intelligent tap. What is Xiaomi’s strategy at home? We are a company that is known by smartphones. It is very recognized in that area, our flagship, but more and more the part of the ecosystem has more relevance. We call “ecosystem” to products that are neither tablets or smartphones: the scooter, the security camera, the televisions and, of course, the appliances. Now we bring the air conditioning already the end of the year the refrigerators and washing machines. Why do we do this? Because we want to offer the consumer more and more products. We know that the smartphones market is very saturated, in penetration rates of more than 110%. Competing there is complicated. And that we are growing and we will continue to do so. But we want to expand the range of options for the consumer to have more capacity to buy our products. Who can do this right now? I think we are the only manufacturer that can offer that variety. How do we want to do it? Through “Human Car Home”. That the connectivity between devices is easy, that you can leave the office, with the smartphone, reach the car and you can connect; that you can see the security cameras of your home; that you may have left something prepared in the kitchen and program. Borja Gómez, Country Manager of Xiaomi Iberia, during the interview at the Xiaomi offices in Spain. It is striking that in that proposal the first thing you bring is an air conditioning because, as a consumer, I would not associate it so intuitively to the connected home. Why have you decided to start in Spain around? We can decide because, as you know, there are a lot of products in China, more than 2,500, and depending on the needs of the final consumer and the possibilities of selling it in the market we are bringing it. With the air conditioning we had to take advantage of: if we did not sell it in summer, later we were not going to be able to sell it. So the moment was now. We also believe it is a device that can be connected very easily. And in Spain, for the temperatures and for the market we have studied, we believe that it can give us good penetration. Is the decision to bring it to Spain very specific? Yes because not all Europe will have the air conditioning, and it is not going to be sold in all areas. In northern Spain the market is smaller than in the south. In Spain and Portugal, in the Peninsula in general, it can be brought by its climatic characteristics. You have mentioned the times and the decision to bring it right now, on July 4. Are you afraid of something late to the air conditioning campaign? We arrive something fair, but we have preferred to launch it now so that consumers can see the entire ecosystem we offer them. The truth is that it is at the limit. Generally the campaigns close in advance, but we do not bring a complicated units of selling. We have the right thing to have coverage throughout this year. I said it also thinking about everything that entails an air conditioning. Maintenance, post-sale service, installation. How are you going to land all this process in Spain for the client? We bring two references … Read more

With the electric consumption triggered by the air conditioning, Singapore has had an idea: buildings that “sweat”

by

Fresh news: it’s hot. A lotand it doesn’t look like This summer is going to give us a break. Bet on Fans or by him air-conditioning It is a solution, but there is a problem: temperatures will continue to increase and Electricity consumed by air conditioning devices It is a problem. Urgently Find passive solutionsand Singapore may have found the key thanks to a new painting. Your secret? Makes buildings “sweat.” Short. In 2022, air conditioning represented 7% of world electricity consumption. The estimate It is that, by 2050, that electrical consumption triggers up to 20%. In order to cool buildings, there are already researchers who are experiencing with heat dissipation solutions to create fresher environments without the need for air conditioning, such as The nanomaterials or a Botijo ​​technology nut rotation. Although we are seeing how to make the air conditioners are more efficient. But there is an easier solution that could be applied to already built buildings: a layer of paint. The Insulating paint It already exists, with examples Like the ultrabrabas developed by the University of Purdue that reflects Up to 98% of the light to maintain surfaces up to 7ºC fresher than other solutions, even under direct sunlight. Now, in Singapore they have developed a painting that mimics the sweating for which we regulate our temperature. Buildings that “sweat”. As we read in Sciencenewsa group of researchers from the Technological University of Nanyang is the responsible of a painting baptized as CCP-30 and what has special is not a color, but its operation. It is developed based on cement and combines three cooling strategies: radiative, reflection and evaporative (the latter, the one that uses our skin). And it works like an organism that sweats. The porous structure of the paint can retain up to 30% of its weight in water, which slowly releases the environment. It’s like the function of air conditioning dehumidificationbut passively. By absorbing water and dissipating heat, the released steam is cooler, contributing to cool the environment. SUV. If the sensation can be similar to that produced with ultrabrabic paint, why invest resources in replicating something that already exists? The main reason is that this ultra -ABANCA painting that reflects heat does not work at all well in Wet environmentssuch as Singapore itself, but also in Thailand and other areas where the moisture percentage is important. This reflected light is trapped by water vapor in the environment, and in large cities the creation of heat spotlights is encouraged. Come on, which contributes to embarrassment. The new porous painting, when not working by reflecting light and heat, does not have this problem and allows the buildings to be correctly isolated, fulfilling that passive cooling function. Promising. To hold their arguments, the researchers painted three houses with different types of paintings. One with a common white paint, another with a commercial painting that only uses radiative cooling and another with its new “sweat” painting. After two years exposed to the sun, rain and humidity of Singapore, while the first two became yellowish, the new formula continued with its white color. That is important not so much for aesthetics, but to continue being efficient reflecting the light. In addition, being prepared to absorb moisture, it does not crack, being another advantage. On the other hand, the house painted with CCP-30 reflected between 88% and 92% of sunlight even when it was wet, and emitted 95% of the heat it absorbed. Tandem with air conditioning. CCP-30 is designed to cover the outside of buildings, not homes or interior areas, acting as a first shield to combat heat. According to the area, the use of air-conditioning It will continue to be necessary to endure high temperatures, but researchers claim that a house covered with its new painting meant between 30% and 40% less use of air conditioning. It does not stop turning the building into a botijo. In the end, as we said, the use of paintings against heat is nothing new, but renewed formulas can help not only to refresh interiors, but to eliminate those urban heat spotlights in cities with a high percentage of moisture, calls “Heat islands”And the good thing about being a painting and not something that require a new construction It can be applied to existing structures without complex reform. I only ask that this type of painting arrives soon, but it is nice to know that passive ways of refrigerating households are being investigated, such as the Cement developed by the Public University of Navarra.

We have a problem with heat in buildings. A Navarra investigation knows how to cool them without air conditioning

by

Every year we repeat the phrase that this has been the year less hot in the coming yearssince it is one of the consequences of climate change. One of the “traditional” ways that we have to refresh in our homes is with an air conditioning system, but poses an economic problem, because the invoices are not paid alone. However, a new Navarro study has managed to find a solution to refrigerate buildings with hardly any energy expenditure. Short. A research team, Formed by Amaia Zuazua Ros from the University of Navarra and Cristina Salazar Castro of the Luredera Technology Center, has developed a project to cool buildings without the need for air conditioning. Under the financing of the Government of Navarra and within the framework of the Navarro R&D System (SINAI)and with the coordination of Aditechthe proposal has sought to boost new passive cooling technologies through modules coated with nanomaterials, designed to eliminate heat from buildings without resorting to electrical systems. The challenge is not less. In the last 30 years, the energy consumption for the cooling of a home is It has tripled. These data, detailed in the International Energy Agency, have highlighted the impact on global electrical demand. For this reason, reducing this consumption without compromising thermal comfort is one of the great challenges of energy efficiency today. The operation. The system is much simpler than it seems. To explain it more easily, the researchers have identified a material that allows to cool the surface of the building, even when exposed to the sun. On the other hand, they have designed a structure to eliminate accumulated heat and thus improve air circulation on the facade by vertical dissipating modules. In addition, they have developed a system to easily adapt to different types of construction. The possibilities. Since the investigation they have detailed that the implementation of these modules in residential and commercial buildings would mean a reduction in energy consumption aimed at refreshing the environment. In addition, in cities with the large amount of solar panels that are being installed and The urban heat island effectthis new system will help mitigate high temperatures from these factors. However, the researchers, who are optimistic, have explained the challenges they have to overcome and how they should observe the long -term application. However, they have added that this technology represents a step forward in the fight against climate change and the design of more sustainable cities. Any other alternative? In the search for sustainable solutions for refrigeration without energy consumption, researchers from different parts of the world are betting on different approaches. An interesting example comes from Indiawhere a system based on recycled clay has been developed. Inspired by botijo ​​technology, this system uses clay cylinders to reduce the ambient temperature by up to 15ºC by evaporation of water, without the need for air conditioning.
