Heat pipe heat exchangers or run-all around coils perform an identical functionality when humidity control is necessary. Two heat exchanger are placed inside the air stream, just one upstream of the cooling coil and the opposite downstream of the cooling coil. These heat exchangers are connected along with piping. A heat transfer fluid, regardless of whether it's water or refrigerant, is possibly pumped or gravity fed from just one heat exchanger to one other. The heat exchanger down stream in the cooling coil (re-heat coil) cools the liquid medium Within the heat exchanger and heats the air passing more than the heat exchanger.
A refrigeration ingredient which make a pressure big difference while in the system which triggers refrigerant to movement.

Refrigerant 22 (R-22 or MonoChloroDiFlouroMethane, CHClF2) is Among the most typical refrigerants helpful resources and is also Utilized in numerous types of applications which include refrigeration, aerosol propellants, cleaning solvents, and foaming agents for plastics. This refrigerant is considered to be partly responsible for harming the earth’s ozone layer and it’s use is being phased out in excess of the next two decades. The ozone layer can be a results of sunlight reacting with oxygen to produce a layer during the stratosphere in excess of 10 km above the earth’s surface area.
