High-temperature sterilization control method and device of air conditioner, air conditioner and storage medium

Abstract

The invention provides a high-temperature sterilization control method and device of an air conditioner, the air conditioner and a storage medium. The method comprises the steps of after receiving a high-temperature sterilization instruction, obtaining a temperature value of an indoor heat exchanger; carrying out bias treatment on a temperature value of the indoor heat exchanger, and obtaining a bias temperature value of the indoor heat exchanger; adjusting the rotating speed of an indoor motor according to the temperature value of the indoor heat exchanger, so that the temperature value of the indoor heat exchanger is maintained within a sterilization temperature interval; and according to the bias temperature value of the indoor heat exchanger, adjusting the frequency of the compressor, the opening degree of the electronic expansion valve and the rotating speed of the outdoor motor, so that the bias temperature value of the indoor heat exchanger is maintained within a sterilization bias temperature interval. According to the high-temperature sterilization control method and device of the air conditioner, the air conditioner and the storage medium provided by the invention, the temperature value of the indoor heat exchanger can be controlled within the sterilization temperature interval, and an outdoor unit can be prevented from triggering overload protection frequency reduction of a refrigerating system, so that the high-temperature sterilization stability is improved while the high-temperature sterilization effect of the air conditioner is guaranteed.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner high temperature sterilization control method and device, an air conditioner and a storage medium. Background technique [0002] With the health needs of users during the use of air conditioners, the high-temperature sterilization function of air conditioners has become the focus of relevant technical personnel. The high-temperature sterilization function of air conditioners is to use the high temperature of indoor heat exchangers to inactivate germs and viruses. When the temperature of the heat exchanger exceeds 56°C and lasts for 30 minutes, the virus can be inactivated. Therefore, the high-temperature sterilization function is to control the coil temperature of the indoor heat exchanger to maintain above 56°C. In addition, the maximum condensing temperature for sterilization should not exceed the maximum condensing pressure of 4.15MPa specified by t...

Problems solved by technology

[0003] However, 56°C and above is generally the heating overload unloading temperature range. If the temperature value of the indoor heat exchanger is controlled in the sterilization temperature range, the heating overload protection point of the air conditioner will be just in the sterilization range, thereby triggering the refrigeration system. The frequency of the overload protection is lowered, thereby reducing the coil temperature of the indoor heat exchanger, which will make the temperature of the indoor heat exchanger lower than the lowest value of the sterilization temperature, thus resulting in reduced or even no sterilization effect. The two contradict each other
