Nowadays, the air-source heat pump has become the choice of many ordinary people. However, when many people buy air-source heat pumps, they do not know the difference between variable frequency and constant frequency air-source heat pumps, so which one should they choose? In fact, both air-source heat pumps have advantages and disadvantages. Let me introduce them to you.
1. Comparison of reliability between constant frequency and variable frequency air source heat pumps: during the whole operation process of constant frequency air source heat pumps, no matter how much the load is, the generator set only operates at one frequency. When the temperature reaches the set temperature, it will shut down, and when the temperature drops to the section, it will restart. The such frequent shutdown will harm the service life of the refrigeration compressor. The variable frequency air source heat pump can automatically adjust the speed according to the change in natural environment temperature, and at the same time, it operates more smoothly, without the feeling of time cooling and time heating. Even if the temperature is achieved, the air source heat pump will not be shut down, and the energy consumption is low.
2. Constant frequency/variable frequency air source heat pump for ultra-low temperature heating: at room temperature, the difference between constant frequency air source heat pump and variable frequency air energy for heating energy consumption is not large, but the lower the temperature, the more significant the difference.
3. Comfort level of constant frequency/variable frequency air source heat pump: because the constant frequency air can be turned off when it reaches the set temperature, it is very easy to cause the room to be cold and hot. The variable frequency electric air source heat pump operates again at a low frequency after setting the temperature to keep the temperature in the room stable. Therefore, compared with constant frequency air energy, variable frequency air energy heating can ensure a more stable temperature in the room.
