Abstract

The invention discloses a constant frequency air conditioning system for improving the indoor comfort degree. The constant frequency air conditioning system comprises a refrigerant circulation circuitwhich is composed of a compressor, an outdoor heat exchanger, a first indoor heat exchanger and a first capillary tube which are connected through a pipeline, the constant frequency air conditioningsystem further comprises a heat exchange branch which is in parallel with the outdoor heat exchanger, wherein the heat exchange branch comprises a first end which communicates with the pipeline between the outdoor heat exchanger and the compressor and a second end which communicates with the pipeline between the outdoor heat exchanger and the first indoor heat exchanger, the heat exchange branch is sequentially connected with an electronic expansion valve and a second indoor heat exchanger in series along the direction from the first end of the heat exchange branch to the second end of the heat exchange branch; the first indoor heat exchanger and the second indoor heat exchanger are correspondingly arranged on the same air supply pipe along the air supply direction; and the constant frequency air conditioning system further comprises a temperature sensor which is used for detecting the indoor ambient temperature and a controller, and when the constant frequency air conditioning systementers a refrigeration mode, the controller adjusts the opening of the electronic expansion valve based on the indoor temperature Ta collected by the temperature sensor.

Description

technical field [0001] The invention relates to the technical field of air-conditioning systems, in particular to a fixed-frequency air-conditioning system for improving indoor comfort. Background technique [0002] With the improvement of air-conditioning popularity, people use air-conditioners more widely in their lives to adjust the temperature of the indoor environment to meet the cooling and heating needs of users. In related technologies, for the cooling control of fixed-frequency air conditioners, the method of reaching the temperature and stopping is generally adopted, that is, in the cooling state of the air conditioner, when the room temperature is lower than the set temperature of the air conditioner and reaches the preset value, the compressor stops working, and the air conditioner stops cooling. , when the room temperature is higher than the set temperature of the air conditioner and reaches the preset value, the compressor starts to work and the air conditioner...
