Problems solved by technology

[0002] When the existing heat pump water heater system defrosts, the operating frequency of the compressor is fixed, that is to say, the output capacity of the compressor is relatively stable, but considering the frosting thickness of the outdoor heat exchanger under different conditions It is not the same, that is to say, the heat required for defrosting is different, so if the defrosting frequency remains the same, the output of defrosting capacity may be small, the defrosting capacity may be insufficient, and the defrosting capacity may also appear. Large output, resulting in energy waste, and even lead to rapid pressure changes, affecting system reliability

Abstract

A defrosting control method, a defrosting control system (300), a computer device (400), and a computer-readable storage medium. The defrosting control method comprises: searching for the defrosting frequency according to the outdoor ambient temperature and the water temperature in response to a defrosting instruction; and running the defrosting mode and controlling a compressor to start at the defrosting frequency. The method ensures the defrosting effect, reduces a waste of energies, and improves the reliability of the system.

Description

technical field [0001] The present invention relates to the technical field of heat pumps, in particular to a defrosting control method, a defrosting control system, a computer device and a computer-readable storage medium. Background technique [0002] When the existing heat pump water heater system defrosts, the operating frequency of the compressor is fixed, that is to say, the output capacity of the compressor is relatively stable, but considering the frosting thickness of the outdoor heat exchanger under different conditions It is not the same, that is to say, the heat required for defrosting is different, so if the defrosting frequency remains the same, the output of defrosting capacity may be small, the defrosting capacity may be insufficient, and the defrosting capacity may also appear. If the output is large, it will cause energy waste, and even cause the pressure to change too fast, which will affect the reliability of the system. Contents of the invention [00...
