When many consumers buy heat pump related products, they will find that many manufacturers have a variety of heat pump products such as water source heat pump, ground source heat pump and air source heat pump. What is the difference between the three?
Air source heat pump
The air source heat pump is driven by the compressor, uses the heat pump in the air as the low-temperature heat source, and transfers the energy to the building through the unit circulation system to meet the needs of users for domestic hot water, heating or air conditioning.
Safe operation and environmental protection: the heat in the air of air source heat pump is the heat source, which does not need to consume natural gas and will not pollute the environment.
Flexible and unrestricted use: compared with solar heating, gas heating and water ground source heat pump, air source heat pump is not limited by geological conditions and gas supply, and is not affected by bad weather such as night, cloudy day, rain and snow. Therefore, it can operate 24 hours a day all year round.
Energy saving technology, power saving and worry saving: air source heat pump is efficient and environment-friendly. Compared with electric heating, it can save up to 75% of electricity charge per month, saving considerable electricity charge for users.
Water source heat pump
The working principle of water source heat pump unit is to transfer the heat in the building to the water source in summer; In winter, the energy is extracted from the water source with relatively constant temperature, and the heat pump principle is used to raise the temperature through air or water as refrigerant, and then sent to the building. Usually, the water source heat pump consumes 1kW of energy, and users can get more than 4kw of heat or cooling capacity. Water source heat pump overcomes the frost of outdoor heat exchanger of air source heat pump in winter, and has high operation reliability and heating efficiency. It is widely used in China in recent years.
In order to protect groundwater sources from pollution, some cities prohibit extraction and utilization; The water source heat pump using river and lake water is also affected by many factors such as seasonal water level decline. There are many restrictions on the use conditions of water source heat pump.
Ground source heat pump
Ground source heat pump is a device that transfers land shallow energy from low-grade heat energy to high-grade heat energy by inputting a small amount of high-grade energy (such as electric energy). Ground source heat pump is a heating central air conditioning system with rock and soil, stratum soil, groundwater or surface water as low-temperature heat source and composed of water ground source heat pump unit, geothermal energy exchange system and system in building. According to the different forms of geothermal energy exchange system, ground source heat pump system is divided into buried pipe ground source heat pump system, groundwater ground source heat pump system and surface water ground source heat pump system.
The price of ground source heat pump is directly related to the residential area. At present, the initial investment cost of household ground source heat pump system is high.
The use of clean energy during the operation of ground source, water source and air source heat pumps can play the role of energy conservation and environmental protection to a certain extent. Although the initial investment cost of air source heat pumps is high, the later operation cost is low, and the long-term use can make up for the installation cost.
