Abstract

The invention relates to the technical field of air conditioner control, and discloses a method used for controlling a double-evaporator air conditioning system. The method includes the steps that anair conditioning system operation mode, a first evaporator coil temperature T1 and a second evaporator coil temperature T2 are obtained; and under the condition that the difference value delta T between the first evaporator coil temperature T1 and the second evaporator coil temperature T2 is larger than a set temperature value, the opening degree Y1 of a first adjusting valve and / or the opening degree Y2 of a second adjusting valve are / is adjusted according to the operation mode of the air conditioning system and the difference value delta T. By means of the method, the operation state of theair conditioning system is adjusted according to the real-time shunting situation of evaporators, the uniformity of the air outlet temperature of the air conditioning system can be effectively improved in time, and the user experience is improved. The invention further discloses a device used for controlling the double-evaporator air conditioning system and an air conditioner.

Description

Technical field[0001]This application relates to the field of air conditioning control technology, for example, to a method and device for controlling a dual-evaporator air conditioning system, and an air conditioner.Background technique[0002]At present, with the continuous improvement of people's living standards, consumers' requirements for air-conditioning have gradually increased, and dual-evaporation air-conditioning systems have emerged. The branches where the two evaporators are located are arranged in parallel, and the outlets of the two evaporators are connected with the inlet of the compressor. The prior art provides a variety of control schemes for dual evaporator air conditioning systems, usually through a simple "T"-shaped three-way split, or two expansion valves with electromagnetic switches are selected to control the electromagnetic expansion valve according to the set time Turn on or off for diversion.[0003]In the process of implementing the embodiments of the prese...
