Air conditioner sterilization control method, device and air conditioner

Abstract

The present invention relates to an air conditioner sterilization control method, device and air conditioner. The air conditioner sterilization control method comprises: after entering the high temperature sterilization mode, controlling the heating operation of the air conditioner; detecting the running time of the heating operation of the air conditioner; When the running time of the heating operation satisfies certain conditions, the tube temperature of the indoor heat exchanger is obtained; the operating status of the air conditioner is determined according to the tube temperature of the indoor heat exchanger, so as to sterilize the indoor heat exchanger. Under the condition of no communication, the method of the present invention simulates the tube temperature of the heat exchanger of the internal machine under the high-temperature sterilization mode by collecting and compensating the exhaust temperature through the exhaust temperature sensing package or obtaining the saturation temperature according to the pressure. By controlling the operating state of the air conditioner, the indoor heat exchanger can be sterilized. The invention realizes the self-cleaning of the indoor evaporator of the non-communication unit, and avoids the problems of low tube temperature of the heat exchanger of the inner unit of the non-communication unit, abnormal operation of unit parameters, and poor reliability.

Description

technical field [0001] The invention relates to the technical field of air conditioner control, in particular to an air conditioner sterilization control method, device and air conditioner. Background technique [0002] The non-communication household unit is a model developed for the United States and other North American countries. It is actually an air-cooled air-conditioning unit. There is no communication between the indoor unit and the outdoor unit for information transmission; the signals of the main board of the air conditioner, such as the indoor ambient temperature and the temperature of the evaporator tube, cannot be processed by the main board of the external unit because the communication signal cannot be output, such as Temperature point shutdown, etc. can only be output through the thermostat to start and stop signals, so that the corresponding status of the air conditioner's internal unit cannot be judged by the external unit main board. [0003] With the de...
