The present invention relates to the technical field of air conditioning, and discloses an electronic expansion valve control method for a one-to-multiple air conditioner and a one-to-multiple air conditioner, including step S1, obtaining the average temperature of the inner coils according to the temperature of the inner coils of each indoor unit Temperature; step S2, obtain the real-time temperature of the inner coil of each indoor unit; step S3, obtain the inner disk of each indoor unit according to the real-time temperature of the inner coil of each indoor unit and the average temperature of the inner coil The temperature difference of the pipe; step S4, confirm that the temperature difference of the inner coil of each indoor unit does not fall within the range of the first preset temperature difference, and set the reference value of the inner coil temperature as the temperature difference of each indoor unit The temperature difference of the inner coil of the air conditioner; obtain the operation mode of the one-drag multi-air conditioner, and adjust the valve opening of the electronic expansion valve according to the relationship between the internal coil temperature reference value and the first valve opening adjustment value. The electronic expansion valve control method has the advantage of being able to finely and accurately adjust the valve opening of the electronic expansion valve.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to an electronic expansion valve control method for a one-drag multi-air conditioner and a one-drag multi-air conditioner. Background technique [0002] At present, the development of the air-conditioning field is becoming more and more mature, and the competition is becoming more and more fierce. With the improvement of consumer requirements, more and more high-rise buildings have decided that each household can only install one air-conditioning outdoor unit. Advanced central air conditioners will become more and more popular with users. Only one outdoor unit can be installed with multiple indoor units to meet the needs of multiple rooms. At present, similar air conditioners with multi-control, one-drag, and small multi-connected air conditioners on the market can meet this requirement. [0003] However, the mainstream electronic expansion valve method of the existing one...
