First, the operating principle
Air source heat pump is driven by a motor, using the energy in the air as a low-temperature heat source, through the condenser or evaporator for heat exchange, and then through the circulation system to extract or release the heat in the building, to meet the user's heating or cooling needs.
Water source heat pump is a heat/cooling source that uses electricity to extract groundwater to heat or cool a building.
Second, the respective advantages
Air source heat pump is heated by heat pump, water and electricity are separated, so there is no impact on the environment. Green, no need to worry about environmental pollution caused by refrigerant leakage; convenient and flexible, without too many restrictions, compared with electric heating, can save about 75% of the monthly electricity bill.
The advantage of water source heat pump is that the groundwater temperature is relatively stable throughout the year, with little fluctuation and COP value greater than 5. While producing the same cooling or heating effect, the water source heat pump is about 30%-40% higher than central air conditioning. The water source heat pump host does not exchange heat with the air, and only needs to be placed in a well-ventilated area of the building.
Compared with traditional heating and air conditioning, air energy heat pump has the advantage of energy saving and environmental protection. In addition, it can provide hot water all year round regardless of the weather. Ground source heat pumps are all heat pumps that use the land as a source of cooling and heating. In fact, there is no difference between air source heat pump and ground source heat pump in terms of working principle. Air energy heat pumps work mainly by absorbing heat from the air, while ground source heat pumps refer to all heat pumps that use the energy of the earth, including ground source heat pumps, ground source heat pumps and surface water source heat pumps.
