Cool the house without air conditioning This is an increasingly necessary problem, since the price of light is more expensive, and the ambient temperature rises. There are all types of scientific projects to achieve it, from the use of absolutely white paint to cements that reflect sunlight. But if the buildings were cooled in the same way as we renew us with summer red? This is obviously with a slightly greater science, that’s what Ice batteries.
These are batteries that, as its name indicates, They use ice to cool buildings. They use night hours when electricity is cheaper and less demand to freeze water and use this ice during the day to cool the rooms.
Frozen water from ice batteries It is placed in tanks that are connected to traditional air conditioning systems buildings. In addition, controllers are integrated that control the process Freezing and fusion of ice. All this has already been done. You can well cool the house. Even a large building. Nevertheless, there are some problems that must be overcome in order to optimize the technique.
The importance of salt in ice batteries
Ice batteries can cool the house, because for such ice to melt, Energy is necessary. In the hottest hours The fusion of ice is causedThis will extract energy in which she needs the inside of the house. Something similar to what is happening with people with sweating is happening. This helps us to cool, because they are warmly cut out of the body to pass water from sweat to a couple of water. In this case, the transition from ice to liquid water, Heat is removed from buildings, Thus, preferring the cooling of their stay. Then this water may again freeze at night.
Logically, this ice is as much as possible in melting. Thus, the process can be extended throughout the hot hours of the day. Thus, the team of scientists from the University of A&M Texas tried last year to add some compounds known as Salt of hydratesThe field is essentially, they are salt crystals containing water molecules in their structure, and in this case, the storage and release of heat in the form of heat helps at the desired temperatures. This can mainly be controlled When the water is frozen and defrost A much more effective way.
Salt helps to freeze water, since its particles act as The nuclei around which ice crystals are formed. This type of hydrated salts has already been checked in the past, but it was difficult to control the process of frozen and defrosting. These scientists have done is to carefully study Thermodynamics of different substances Candidates, while they can not control more correctly.
You can cool such a house, but there is a long way forward
Many companies are already offering an ice battery installation service. They are even installed in large buildings, for example Eleven Madison in New York. Despite this, it is clear that this is a process that needs great optimization, especially so that it can be used as long as possible. Some companies already offer 20 years of performance without maintenance, but it is expected that at some moment it can be even more. As we already said at the beginning, seeing what is happening with a change in the climate, the more the technique is the prefect, the better.
