Condensers, cooling towers and evaporators

Goal capacitor in paro compression cycle - hot, high-pressure gas from the compressor and the cooling remove the first overheating, and then latent heat, so that the refrigerant is condensed into a liquid. In addition, the liquid is usually slightly subcooled. In almost all cases, the cooling air or water.

Goal evaporator obtaining low-pressure, low temperature of the liquid from the expansion valve and bring her in close thermal contact with the load. Refrigerant takes its latent heat load and leaves the evaporator in the form of dry gas. Evaporators are classified according to their refrigerant flow pattern and their functions.

flow can be one of two types. Or the refrigerant continuously passed through a heat exchanger, while it evaporates and becomes overheated, or he is in a vessel under reduced pressure, while it evaporates or from which it was taken in some coolers, returning as liquid and gaseous mixture.
The most common type of far continuous stream type, called direct expansion evaporator.

Function evaporator cold air or liquid in almost all cases. Air or liquid, and then cools down load. For example, cooled, air-cooled and circulated to save the contents of the set temperature; water chiller system, water circulates in some fan-coil units to provide air conditioning. In heat pumps a function can be described as the recovery of heat from the air or liquid, but evaporator construction will be very similar.....
