Cause air source heat pump operation cause heating to become the mainstream

Release Time：2021-07-21

In hot summer and cold winter areas, the outdoor air temperature of low-temperature heat pump can reach -20 ℃ in winter, but the dry bulb temperature of winter heating capacity given on the existing air source heat pump unit sample (or nameplate) is 7 ℃ and the wet bulb temperature is 6 ℃. In winter, when the ambient temperature is lower than -10 ℃, in actual operation, the heating capacity of air source heat pump unit in winter is attenuated, there are two reasons for the attenuation of the air source heat pump unit in winter:
1. When the outdoor temperature is lower than 7 ℃, on the one hand, frost on the surface of the outdoor side heat exchanger will increase the heat exchange resistance and reduce the heat exchange per unit time. On the other hand, in order to remove the frost layer on the coil, the unit has to make periodic short-term reversing operation, changing from heating condition to cooling condition, which will inevitably lead to the reduction of the actual heating operation time of the unit, thus affecting the heat provided to the indoor, this part of the heat attenuation is relatively limited, roughly 5% ~ 7%, and the unit more in the air temperature -5~7 ℃ frosting, with the decrease of outdoor temperature, due to the decrease of moisture content in the air, the probability of frosting does not increase but decreases.
2. Simply put, due to the decrease of outdoor temperature, the air source heat pump hot water unit absorbs the heat of the air source heat pump in the outdoor air when it is working, and transfers it to the water on the user side after lifting. Obviously, the lower the temperature, the more It is not easy to absorb and improve, the lower the efficiency, which directly leads to the reduction of the heat pump unit.
The popularization and application of air source heat pump heating is not only from the perspective of safety and energy saving, but also from the comfort of user experience. Air source heat pump heating provides users with a healthy and natural, high quality heating and bathing enjoyment.
People's awareness of environmental protection is getting higher and higher, and new environmental protection requirements are also put forward for daily necessities. Hot water is a big problem. Traditional hot water supply and air source heat pump rely on burning coal and other substances. This hot water supply method will produce great pollution and greatly reduce the quality of our living environment. Consumers have put forward new requirements for hot water supply, as a new type of environmental protection hot water supply system, air source heat pump system just meets the new demand of consumers for environmental protection of hot water system.
With the development of the economy, in the global energy supply is becoming increasingly tight and environmental protection issues are also increasingly prominent environment, air source heat pump system with its high efficiency and energy saving, environmental protection, safety, comfort, convenient installation and many other advantages, quickly in the market by the user's recognition.
