With the vigorous promotion of the concept of "energy saving and environmental protection" in various countries, more and more consumers are paying attention to energy-saving products. Combining the characteristics of "safety, environmental protection, and energy saving", Gradually enter people's lives. With the advancement of science and technology, the air source heat pump has changed from the original fixed frequency to the current inverter air source heat pump. So, what is the difference between the two? What are the advantages of inverter air source heat pumps compared with Fixed frequency heat pump?

 

 

 

1.The inverter air source heat pump is different from the fixed frequency energy saving.

 

Since the operating speed of the fixed-frequency air source heat pump compressor is fixed, if the temperature is too high or too low, the compressor can only be turned off and on again by human operation, and when the compressor encounters electrical failures such as unstable voltage, the compressor It will stop rotating. Such frequent shutdowns and restarts will consume a lot of electricity and greatly reduce the life of the compressor; and the variable-frequency air source heat pump can adjust the operating speed of the compressor at any time, and the compressor will not be turned on frequently, which is much less This reduces the power loss caused by frequent shutdowns and restarts.

 

 

 

2. The working voltage of the two is different.

 

The working frequency of the compressor of the fixed frequency air source heat pump is immutable, and it can only be operated under the specified voltage, that is, the national household grid voltage (220V/50HZ). The voltage is high or low and cannot be operated; while the inverter air source The heat pump can operate under a wide voltage range of 130~280V, with lower voltage requirements and stronger applicability.

3.The temperature adjustment speed of the two is different.

 

The fixed frequency air source heat pump can only work at a fixed frequency, and the temperature adjustment speed is relatively slow when it is started; while the inverter air source heat pump works at a relatively high frequency after it is started, and it will soon rise to the set temperature, and then decrease Operating frequency to maintain indoor temperature.

 

4.The variable frequency air can better adapt to the low temperature environment.

 

Compared with the fixed frequency air source heat pump, the inverter air source heat pump has an additional frequency converter. This frequency converter is an air source heat pump that can automatically adjust the compressor operating frequency according to the ambient temperature. When the unit needs defrosting, the frequency conversion air source will use high frequency Operation, the defrosting time is greatly reduced, thereby improving the heating efficiency.

 

The above is an introduction to "What are the advantages of inverter air source heat pumps compared to fixed frequency air source heat pumps". Users can choose the appropriate air source heat pump according to their own conditions.
