What is the working principle of a hot water heat pump?

The working principle of the hot water heat pump heating in winter: the hot water heat pump takes the groundwater from the water extraction well and sends it to the hot water heat pump unit. The unit absorbs the low-grade groundwater of heat energy, and then it is sent back to the ground and the earth to heat again after being charged well. Exchange to increase heat energy, and then reuse.

The liquid refrigerant in the hot water heat pump unit absorbs the low-level heat energy of the groundwater in the evaporator and evaporates into a low-temperature and low-pressure gaseous refrigerant. The compressor (using a fully enclosed flexible scroll compressor with reliable operation and high heating efficiency) compresses it into a high temperature and high-pressure gaseous refrigerant, and then sends it out of the condenser. The high-temperature and high-pressure gaseous refrigerant in the condenser transfer heat to the building's circulating water (geothermal or heating radiator) through heat exchange. After dissipating the heat to the building, it condenses into a liquid state and then returns to the hot water heat pump evaporator to repeat.

What conditions should a hot water heat pump have in its application?

(1) Reliable water source

Just listen to the name of the hot water heat pump to know how important the water source is. A reliable water source is the first requirement in the application. The water source can be surface water, rivers, lakes, and groundwater. Groundwater is widely used. As groundwater is one of the country's important resources, the government has restrictions and regulations on the exploitation and use of it. Therefore, before installing a hot water heat pump, it must first be checked by relevant government departments.


(2) Sufficient water

The amount of water can be related to the cooling or heating efficiency of the hot water heat pump, so before determining the plan, the amount of water should be determined, and pumping experiments should be carried out when necessary to see if the groundwater level drop during the continuous pumping time meets the requirements.


(3) Water temperature

The temperature of the water source is also an important factor affecting the hot water heat pump. The same unit provides different cold and heat due to different water temperatures. Generally speaking, the range of hot water heat pump requirements for water source temperature is: under cooling conditions, the water temperature into the evaporator is 10-22°C; under heating conditions, the water temperature into the condenser is 18-40°C.


It is the responsibility of each manufacturer to produce hot water heat pumps that meet the standards, to ensure the healthy development of the hot water heat pumps market. MICOE conducts many tests on hot water heat pumps before they leave the factory, and the quality qualification rate is guaranteed.
