Cooling cooling heat dissipation

When heat is transferred, the temperature of the substance he moved from drops, while the temperature of the substance travels rises. Let's look at two practical purposes, this principle is used in refrigeration.

The first is a living space, cooled Central air conditioning system. In order to cool space, heat must be moved from the air in the room air in the street. It occurs in several stages, as we will explain. As shown in 1, the heat is transferred from the air in the premises of the refrigerant circulating through the evaporator. In this case, the temperature of the air flowing through the evaporator fall. Now in 2 heat is absorbed by the refrigerant in the evaporator and moves together with a capacitor. Then heat moves from the refrigerant in the outer air. This leads outside temperature rises, as it passes through the condenser. Then, as shown in zones 3 and 4 heat from the refrigerant, it is circulated back to the evaporator repeat the process.

Refrigerator is another example of how the movement of heat to the cooling associated with the cosmic temperature. To keep food cold and avoid spoilage, heat must be moved from the food to the air. As in air conditioning example, this occurs in several stages. First, heat moves from food in the surrounding cooler air. This increases the temperature of the air and lowers the temperature of the food. Next hot air moves the refrigerant circulating through the evaporator. In this case the temperature of the air coming off the coil fall.

That heat, then moved with the refrigerant flow to the condenser coil (at the bottom), where he moves from the refrigerant air circulating through the coil. This causes the room air temperature rise. In both examples, refrigeration moved heat, a few steps from the place where he wasn't wanted, to the place where he was less controversial. The result was a decrease in temperature in the zone of heat was removed and a rise of temperature in the area where the heat was transported...
