The invention relates to an air conditioning system control method, device, control equipment, a medium and an air conditioning system. The control method comprises the steps of obtaining current working parameters of the air conditioning system, determining the relative relationship between the current working parameters and reference working parameters, controlling a compressor to operate from the reference exhaust temperature to the target exhaust temperature according to the relative relationship, and / or controlling the compressor to operate from the reference frequency upper limit to thetarget frequency upper limit. The exhaust temperature and / or frequency upper limit of the compressor of the air conditioning system can meet the demand under the current connection pipe length, the accumulation of refrigerant in a flash vessel is reduced, air suction belt liquid in the air filling and enthalpy adding process the compressor is reduced, and the operation reliability of the air conditioning system is high.
Description
technical field [0001] The invention relates to the technical field of air conditioning, in particular to a control method, device, control equipment, medium and air conditioning system of an air conditioning system. Background technique [0002] In a two-stage compression system, the enthalpy injection generally adopts a flash evaporator. After the liquid refrigerant flows out of the condenser, a part of gas is generated after being throttled by the electronic expansion valve, and is sprayed into the compressor from the enthalpy increasing pipe by means of the flash evaporator. Add air to the compressor to increase enthalpy. If the liquid level in the flash evaporator is too high, it is easy to cause the suction of the enthalpy increase port of the compressor to carry liquid, which will affect the compressor itself and the entire air conditioning system. [0003] In some occasions, due to location constraints, it is necessary to consider shortening or lengthening the conne...
