The invention provides a control method and a control device for an air conditioner, a processor and an air conditioning system. The air conditioner comprises a first condenser, a second condenser, anevaporator, a compressor, a bypass valve and a throttle valve, wherein an outlet of the compressor is connected with an inlet of the evaporator through the bypass valve, the outlet of the compressoris further communicated with an inlet of the first condenser, the outlet of the compressor is further connected with an inlet of the second condenser, the outlet of the first condenser and the outletof the second condenser are connected with the inlet of the evaporator through the throttling valve, the outlet of the evaporator is connected with the inlet of the compressor, the outlet of the evaporator is connected with the inlet of the second condenser, and the outlet of the evaporator is connected with the outlet of the second condenser. The method comprises the steps: under the condition that a low-pressure protection phenomenon occurs to the air conditioner, acquiring an external environment temperature; and controlling the opening degree of the throttle valve and / or the state of the bypass valve till the low-pressure protection phenomenon does not occur any more according to the external environment temperature. The method avoids startup abnormity caused by the fact that the air conditioner cannot return to normal.
Description
technical field [0001] The present application relates to the field of air conditioners, and in particular, relates to an air conditioner control method, a control device, a computer-readable storage medium, a processor, and an air conditioner system. Background technique [0002] At present, there are not many occasions where air conditioners need low-temperature refrigeration, and most household models do not need to operate in cooling mode in low-temperature environments. However, cryogenic refrigeration is often required in applications that cool equipment. [0003] However, due to improper design of some models, there will be abnormal conditions such as low-pressure protection during low-temperature refrigeration start-up, which will cause the unit to start abnormally. [0004] Therefore, there is an urgent need for a method that can alleviate or avoid the above-mentioned problems. [0005] The above information disclosed in the Background section is only to enhance t...
