Abstract

The embodiment of the invention provides an air-conditioner control method and an air-conditioner. The air-conditioner control method comprises the steps that after the air-conditioner is started, thedegree of superheat of the exhaust end of a compressor of the air-conditioner is detected in real time; when the degree of superheat of the exhaust end is smaller than the degree of superheat of a first preset exhaust end, timing is started; when the timing duration is larger than a first preset duration, the opening degree of a valve between an indoor heat exchanger and an outdoor heat exchangerof the air-conditioner is reduced, the degree of superheat of the exhaust end is improved, under the condition that the degree of superheat of the exhaust end is low, a large amount of lubricating oil can be carried in exhaust gas, and consequently the condition that the amount of lubricating oil in the compressor is reduced is caused; and in order to solve the problem, the opening degree of thevalve between the indoor heat exchanger and the outdoor heat exchanger of the air-conditioner is reduced, a low pressure refrigerant between the valve and the compressor can be pumped away through normal running of the compressor, the degree of superheat of the exhaust end of the compressor can be improved, the oil discharging amount of the compressor is reduced, and normal running of the compressor is guaranteed.

Description

technical field [0001] The present invention relates to the field of refrigeration equipment, and more specifically, to an air conditioner control method and the air conditioner. Background technique [0002] The compressor is the heart of a vapor compression air conditioning system, powering the cycle of refrigerant in the system. The compressor is a high-speed rotating part, and lubricating oil is one of the key factors to ensure the normal operation of the compressor. During the operation of the vapor compression air-conditioning system, a part of the lubricating oil will be brought out by the compressor during the process of discharging the high-temperature and high-pressure refrigerant. After long-term operation, the amount of lubricating oil in the compressor will inevitably decrease, and the compressor will not work properly due to the lack of lubricating oil. Work. There are two main solutions at present: one is to install an oil separator at the exhaust port of th...
