Introduction to the working principle and advantages of variable frequency air energy heat pump

2018-08-28

A few years ago, the variable frequency air energy heat pump was still a strange word for the people. However,  in recent years, with the development of air energy heat pump  technology, especially the UTL/VKIN, the leading brand of air energy in  2007, the first variable frequency air energy product has been  introduced. “No frequency conversion and no air energy” has become a  fashion, frequency conversion. Air energy heat pumps have gradually become the mainstream of choice for the people. So, what exactly is a variable frequency air energy heat pump? What are the advantages of variable frequency air energy heat pumps?


The so-called "frequency conversion" is to change the frequency. “Frequency”  refers to the number of times a periodic change is completed in a unit  of time, and is an amount describing the frequency of periodic motion.

Compared  with the traditional fixed-frequency air energy heat pump, the variable  frequency air energy heat pump has an additional "inverter". This  "frequency converter" allows the air energy heat pump to automatically  adjust the operation of the compressor based on changes in the outdoor  ambient temperature. When  the outdoor temperature is relatively low, the frequency converter can  speed up the operation of the air energy heat pump, thereby improving  the heating capacity of the heat pump, so that the air energy heat pump  can adapt to work in a low temperature environment; when the outdoor  temperature is relatively high, the frequency converter can Let the air energy heat pump run slower, which will save energy.

Simply  put, the existence of the inverter is like the gear position of the  electric fan. When the heat is high, the speed of the fan blade is  increased, and the wind blows out is relatively large. When the weather  is cold, the low gear is opened. The frequency of operation is slower, and the wind blown out will be smaller.

In  addition to the variable frequency air energy heat pump, the heating  efficiency of the air energy heat pump can be improved in a low  temperature environment, and the life of the air energy heat pump can be  improved and the energy consumption can be reduced.
 
As we all know, such equipment, if it is turned on and off, will reduce the service life of the appliance. The  traditional fixed-frequency air energy heat pump will automatically  stop when the temperature in the water tank reaches the set temperature;  if it does not reach the set temperature, it will automatically start. Although  such a setting is convenient and trouble-free, frequent starting and  stopping will not only increase the consumption of electric energy, but  also reduce the service life of the air-energy heat pump compressor.

 
However,  the variable frequency air energy heat pump is different. After  reaching the set temperature, the variable frequency air energy heat  pump will still work at low frequency. This method will not only  increase the power consumption, but also maintain the stability of the  indoor temperature and make the heating more comfortable.
