Heat Pumps – how they work

Sunday, February 6th, 2011

Heat pump + Solar water heating = up to 91% efficiency

How a heat pump works:

A heat pump replaces the current geyser’s electrical
element thereby saving money.
Refrigerant gas is circulated in a continuous cycle. The liquefied refrigerant passes under pressure through an expansion valve in to a partial vacuum.  The sudden expansion of the high pressure liquid into a low pressure area (the evaporator) cools the gas down.  The refrigerant gas which is now at a comparatively low temperature is then suddenly pressurized by a compressor.

The sudden increase in pressure raises the temperature of the refrigerant gas considerably.  This heated gas is routes through a condenser and emits heat to the water that is to be heated in a storage tank near the actual heat pump.  It can also be emitted into the surrounding atmosphere in the case of a refrigerator or air conditioning system.
