Problems solved by technology

[0002] At present, when the inverter air conditioner is running in low-temperature heating operation, the electronic expansion valve is generally controlled by a fixed opening, but this control method will cause the air conditioner to run in a low-temperature environment, with the frosting refrigerant flow of the outdoor unit decreasing continuously, causing the air conditioner to The output capacity of the valve is seriously attenuated, and the flow rate of the valve body is different during multiple operations, and the capacity output is unstable

[0077] refer to figure 2 , the first embodiment of the electronic expansion valve control method of the present invention is proposed, and the electronic expansion valve control method includes:

[0078] Step S10, when the air conditioner enters the low-temperature heating mode, obtain the outdoor ambient temperature;

[0079] The heating temperature of the air conditioner in the normal heating mode is generally higher, and the heating temperature range can generally reach 17°C to 30°C; and when the air conditioner is in the low-temperature heating mode, the heating temperature is higher than that of the conventional heating mode. The heating temperature is low, and its heating temperature range is generally set at 8°C to 16°C. Before step S10, when the air conditioner is in heating operation, the outdoor ambient temperature is acquired; when the outdoor ambient temperature is less than or equal to a temperature threshold, the air conditioner is controlled to enter the low-t...

Abstract

The invention discloses an electronic expansion valve control method. The method comprises the following steps of acquiring outdoor environment temperature when an air conditioner enters a low-temperature heating mode; controlling the operation of an electronic expansion valve for a first preset duration according to the outdoor environment temperature; acquiring the current actual exhaust temperature and target exhaust temperature of an compressor; and adjusting the opening degree of the electronic expansion valve according to the actual exhaust temperature and the target exhaust temperature.The invention further discloses an electronic expansion valve control device, the air conditioner and a readable storage medium, and aims to improve the output of system heating capacity and the stability of heating output.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an electronic expansion valve control method, an electronic expansion valve control device, an air conditioner and a readable storage medium. Background technique [0002] At present, when the inverter air conditioner is running in low-temperature heating operation, the electronic expansion valve is generally controlled by a fixed opening, but this control method will cause the air conditioner to run in a low-temperature environment, with the frosting refrigerant flow of the outdoor unit decreasing continuously, causing the air conditioner to The output capacity of the valve is severely attenuated, and the flow rate of the valve body is different during multiple operations, and the capacity output is unstable. [0003] The above content is only used to assist in understanding the technical solution of the present invention, and does not mean that the above content is adm...
