Problems solved by technology

At the same time, the operation of the compressor under the condition of lack of lubricating oil will cause the wear of the compressor and reduce the service life of the compressor
At present, the most commonly used oil return method in the heating mode is to change the direction of the four-way reversing valve to return the oil from the heating mode to the cooling mode. At this time, the air conditioner suspends heating, which seriously affects the comfort of the user.

specific Embodiment

[0047] Some specific embodiments, specifically include,

[0048] Determine the lower limit of the compressor operating frequency in the oil return mode of the air conditioner by the following formula:

[0049] F 1 =Min{F 2 ,F 2 +a*(T 2 -T 1 )};

[0050] of which: F 1 is the lower limit of the compressor operating frequency in oil return mode; F 2 is the required oil return frequency of the compressor in normal operation mode; T 1 is the current outdoor real-time ambient temperature; T 2 is the outdoor ambient temperature in the normal operation mode in winter; a is the coefficient of the difference between the outdoor ambient temperature in the normal operation mode of the air conditioner in winter and the current outdoor real-time ambient temperature.

[0051] In terms of compressor operating frequency correction, the outdoor ambient temperature will affect the range of compressor frequency boosting. When the ambient temperature increases, the viscosity of the lubri...

Abstract

The present invention provides an air conditioner control method, device, air conditioner and storage medium, and relates to the technical field of air conditioners. The control method includes: when receiving an instruction to operate in an oil return mode, obtain the current outdoor real-time ambient temperature and indoor The opening degree of the electronic expansion valve; controlling the lower limit value of the operating frequency of the compressor when operating in the oil return mode according to the current outdoor real-time ambient temperature; and controlling the indoor electronic expansion valve according to the preset opening degree of the electronic expansion valve of the opening. With regard to the existing technology, the present invention can prevent oil return heating of the indoor unit of the air conditioner from suspending oil return and heat supply without reversing when the air conditioner is heating in winter, thereby improving user comfort.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, and in particular, to a control method, device, air conditioner and storage medium of an air conditioner. Background technique [0002] In the prior art, the problem of compressor oil return has always been a key problem to be overcome in the air-conditioning industry. When the air-conditioning system is running, the lubricating oil in the compressor will be taken out of the compressor along with the flow of refrigerant and accumulated in the two devices, which will make the heat exchange effect of the evaporator and the condenser worse, and seriously affect the heat exchange effect. and system performance. Especially for a multi-connected system, due to the large number of indoor units, the opening of the electronic expansion valve of each indoor unit is also different, and a lot of lubricating oil is accumulated in the indoor unit. At the same time, the operation of the compr...
