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

Embodiment Construction

[0027] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary, and embodiments of the present invention are described in detail below.

[0028] First, briefly describe the communication principle of the indoor and outdoor units of the air conditioner. An air conditioner, such as a split type air conditioner, is generally composed of an indoor unit, an outdoor unit, a connection pipe, and a connection line, wherein the connection line includes a communication line. The indoor unit controller sends a frame of detected data packet to the outdoor unit controller at a fixed communication cycle, and at the same time, receives a frame of data packet sent by the outdoor unit controller. Specifically, the data packet sent by the indoor unit controller to the outdoor unit controller may include data such as indoor ambient temperature, indoor heat exchanger coil temperature, humidity, set temperature,...

Abstract

The present invention proposes a high-temperature sterilization control method and device for an air conditioner, an air conditioner, and a storage medium. The method includes: after receiving a high-temperature sterilization instruction, obtaining the temperature value of the indoor heat exchanger; Bias processing to obtain the bias temperature value of the indoor heat exchanger; adjust the speed of the 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 the sterilization temperature range; The bias temperature value of the heat exchanger is adjusted to the frequency of the compressor, the opening of the electronic expansion valve and the speed of the outdoor motor, so that the bias temperature value of the indoor heat exchanger is maintained within the sterilization bias temperature range. The invention can not only control the temperature value of the indoor heat exchanger in the sterilization temperature range, but also prevent the outdoor unit from triggering the overload protection frequency reduction of the refrigeration system, and improve the stability of the high-temperature sterilization while ensuring the high-temperature sterilization effect of the air conditioner.

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...
