2023-04-09
As a new type of energy-saving and environment-friendly equipment, the air source heat pump has the characteristics of stability, reliability, environmental protection, energy saving, safety and convenience, and is widely used in heating, cooling, hot water supply and other fields of civil and commercial buildings. So, what is the working principle of an air source heat pump? 1. The principle of air source heat pump The air source heat pump utilizes the heat energy naturally present in the air, and realizes the conversion of low-temperature heat energy to high-temperature heat energy through cyclic operation, so as to realize the functions of indoor heating and cooling. It is mainly composed of outdoor unit, indoor unit and pipeline. 
2. Working process of air source heat pump 1. Heating process When the indoor temperature is lower than the set value, the heat pump system starts, the outdoor unit absorbs the heat energy in the air, generates heat energy through the evaporation of the refrigerant and compresses the refrigerant to increase its temperature, and then the high-temperature and high-pressure refrigerant is transported through the pipeline To the indoor unit, the heat energy released by the refrigerant in the indoor unit is absorbed by the indoor heat exchanger, and the indoor temperature gradually rises to the set value. 2. Refrigeration process When the indoor temperature is higher than the set value, the heat pump system starts, the indoor machine absorbs the indoor heat energy, the refrigerant becomes a low-temperature and low-pressure state at the expansion valve in the pipeline, and then is transported to the outdoor unit through the pipeline, and the compressor converts the refrigerant Compressing and raising its temperature at the same time, the refrigerant releases heat energy into the air through the heat exchanger, making the heat energy in the air become lower. 3. Advantages of air source heat pump 1. Environmental protection and energy saving: AIR SOURCE HEAT PUMPS can effectively utilize the heat energy naturally existing in the air, do not need to burn fossil fuels, will not cause harmful gas emissions such as carbon dioxide, and have no pollution to the environment. 2. Easy to install: The installation and maintenance of Air Source Heat Pumps are relatively simple, and do not require additional facilities such as chimneys and combustion chambers, and will not cause indoor pollution and safety hazards. 3. Accurate temperature control: The air source heat pump can be set according to different indoor temperatures to achieve precise temperature control, which not only ensures indoor comfort, but also saves energy. Fourth, the scope of application of air source heat pump 1. Independent houses: Air source heat pumps are suitable for all kinds of independent houses, including villas, apartments, bungalows, etc. 2. Commercial buildings: Air source heat pumps can be used in various commercial buildings, such as hotels, shopping malls, supermarkets, office buildings, etc., to achieve multiple functions such as heating, cooling and hot water supply. 
3. Industrial buildings: Air source heat pumps can also be used in various industrial buildings, such as factories, warehouses, etc. Five, the application prospect of air source heat pump At present, with the popularization of the concept of energy saving and environmental protection, the application prospects of air source heat pumps are becoming more and more broad. In the future, air source heat pumps will replace traditional heating methods and become the mainstream of green energy, bringing people a more comfortable, safe and environmentally friendly life.
