How Does a Heat Pump Work

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.
