How effective is the air source heat pump?

The air energy heat pump consumes a small amount of electricity from the air to obtain heat for heating. The change of temperature affects its heating capacity. It can be said that the heating of the air energy heat pump has been changing. The lower the temperature, the smaller the heating capacity. Whether the heating capacity at the lowest temperature meets the heating needs. Different types of buildings have different requirements for unit heat load. Generally, 80 watts/square meter is enough for residential buildings in Beijing. The heating effect is better for one machine and 20 square meters, and the indoor temperature is 18-22 degrees.

Due to the fierce price competition in the air energy heat pump heating market, dealers will not be too high when selecting models for users. If the heating pipe insulation is poor or the house insulation is poor, it will seriously affect the heating effect. A gas station used to use coal boilers for heating, with a heating area of 400 square meters, but now it uses a 15-degree air heat pump for heating, and it was found that the effect was not good during use. After verification, the heating pipes are not insulated, the gas station has a car wash room, and the open doors and windows have a large heat dissipation, resulting in poor heating effect, and the water temperature can only reach 30-35 degrees.
