It is known to all that like water flows towards the
lower level, heat is transferred to the lower-temperature object from the one
of higher temperature. But actually faced with the energy deficiency, we design
to collect the low-temperature heat in nature such as from the air and from the
river water. Heat pumps make use of such heat for water and air heating.
Heat pumps work similar as what an air conditioner does. Generally,
a cooling system (with a compressor) is made of four main parts: compressor, condenser,
throttling valve and evaporator. The liquid refrigerant with low temperature
and low pressure absorbs heat collected by the evaporator and then becomes
low-pressure gas. Then it is pressed into high-temperature and high-pressure
gas in the compressor. It passes its own heat to the cold water and turns into
liquid with high temperature. Moving through the throttling components (capillary
tubes, thermostatic expansion valve and electronic expansion valve), refrigerant
becomes low-temperature and low-pressure. This a whole cooling cycle.
