Anatomy of  Air Conditioning

The air conditioning compressor elevates the pressure of the refrigerant to a point where it can be condensed to a liquid by the available sink temperature. A high-pressure gas enters the air conditioning condenser and a high-pressure liquid leaves the condenser. This liquid is hot, say 105°. At the expansion valve, the pressure is reduced. As the pressure is reduced, the boiling point is reduced and some of the liquid flashes or boils. About 19% of the liquid boils, cooling the remaining liquid to 40°. At the air conditioning evaporator, heat is absorbed or flows from the hot source to the cold refrigerant, causing it all to boil. The air conditioning evaporator is inside the box and it is cold. Put your hand behind the box and, if the unit is running, you will feel heat. This is the heat absorbed inside the box. Because a air conditioning system absorbs heat at one point, and pumps it to another point to be rejected, it can be called a heat pump. The air conditioning condenser can take many forms. It can be a shell and tube heat exchanger, where water flows through the tubes and the refrigerant flows through the shell. The water absorbs heat, liquefying the gaseous refrigerant. The water is either wasted to the sewer, or taken to a cooling tower or spray pond to be cooled so it can be reused. Another air conditioning condenser is the air-cooled type. Here, the refrigerant flows through a finned coil over which outside air is blown. This air removes heat and liquefies the refrigerant. Which then flows to a liquid receiver for storage. Problems can occur at high and low air temperatures. At high air temperatures, the air conditioning condenser capacity decreases and so decreases the system capacity. It is important to be generous in selection of this equipment. On the other hand, all this surface causes problems at low air temperatures. It can condense gas at so low a pressure that the air conditioning machine cannot operate properly and safety controls will shut it off. Fortunately, there are accessories available which can prevent this low-pressure condition from occurring.
Another type of air conditioning condenser is the evaporative condenser. This is an air-cooled condenser whose efficiency is increased by spraying water on the condenser coil. The evaporation of water increases the cooling effect.
