With the development of recent years, the technology of air source heat pump has also been greatly upgraded, of which DC inverter air source heat pump has gradually become the mainstream choice of families and businesses. So, why is DC inverter air source heat pump becoming more and more popular? Now let's get to know the comparison between inverter heat pumps and on/off heat pumps.

During the operation of non-inverter air source heat pump, no matter how heavy the load is, the heat pump unit can only operate at one frequency. When the temperature reaches the set temperature, the unit will stop. It does not restart until the temperature drops to the range. Such frequent shutdown and restart will not only consume electricity, but also affect the life of the compressor. DC inverter air source heat pump can automatically adjust the compressor's speed according to the change of ambient temperature, and at the same time, the temperature keeps more stable. Even if it reaches the set temperature, the unit will not stop but maintain operation with low energy consumption. Therefore, in terms of service life, energy consumption and service life, DC inverter air source heat pump is better than on/off heat pump.

Heating Efficiency

At room temperature, the heating efficiency of on/off air source heat pump and DC inverter heat pump is similar, but the lower the temperature is, the more obvious the difference will become. Take DC inverter heat pump air conditioner as an example. At 15℃- 20℃, the heating capacity difference between on/off heat pump and DC inverter heat pump is less than 10%. At minus 15℃, the heating capacity of inverter heat pump is about 60% higher than that of non-inverter heat pump, and at minus 25℃, the gap is increased to 80%. Thus, it can be concluded that the best heating choice for low ambient temperature areas is DC inverter heat pump, otherwise it cannot provide stable and sustainable indoor warmth.

Comfort Level

Because on/off air source heat pump may shut down after the set temperature, it is easy to cause unstable indoor temperature, making people feel a little uncomfortable. In contrast, DC inverter heat pump can continue to operate at low frequency after reaching the set temperature in order to maintain the stability of indoor temperature. Therefore, compared with on/off heat pump, DC inverter heat pump can ensure more stable indoor temperature.
