Difference in definition

Constant frequency air energy heat pump is to heat or refrigerate by controlling the operation of the compressor, and the power supply frequency cannot be changed. Constant frequency air energy heat pump compressor speed basically does not change, when the temperature reaches the set temperature, the compressor stops working, on the contrary, it starts to work, relying on constantly starting and stopping the compressor to adjust the temperature. DC inverter swimming pool heat pump is the inverter press using frequency conversion control technology, according to the environmental temperature automatically selects heating, refrigeration, and dehumidification operation. It makes the room quickly reach the required temperature in a short time, and in the state of low speed, and low energy consumption with small temperature fluctuations, to achieve fast energy saving, and a comfortable temperature control effect.

The difference in performance at different temperatures

Usually, the lower the temperature is, the more obvious the difference between a DC inverter swimming pool heat pump and a fixed frequency DC inverter swimming pool heat pump. At 15℃ ~ 20℃, the difference between the frequency conversion air energy heat pump and the constant frequency air energy heat pump is less than 10%. At -15℃, the heating capacity of a variable frequency air energy heat pump is about 60% higher than that of a fixed frequency air energy heat pump. At -25℃, the difference increases to 80%. Therefore, a frequency conversion air source heat pump is very suitable for heating and heating in areas with low ambient temperatures.

Energy saving difference

Constant frequency air source heat pump to open and stop frequently to adjust the temperature, start the strong current input, very power consumption, because it can not adjust the frequency of the compressor according to the specific situation, when the output heat is not needed by the user will cause greater waste. When the DC inverter swimming pool heat pump system starts, the current is low and there is no impact on the power grid and the electricity meter. This will reduce interference with other appliances in use in the room. Output on demand, to ensure uninterrupted operation in most working conditions, energy saving advantage is more obvious.

The difference in operation mode

Constant frequency air source heat pump can only run at one frequency during operation. When the temperature reaches the set temperature, it will stop, and when the temperature drops to the interval, it will restart. Frequent shutdown and restart not only consume power but also negatively affect the life of the compressor. DC inverter swimming pool heat pump can automatically adjust the RPM of the compressor according to the ambient temperature change so that the operation is more stable. Even if the temperature is reached, it will not stop, but maintain the operation with low energy consumption, reduce energy consumption, and prolong the service life of the unit.
