Air conditioning system and dehumidification control method

Abstract

The invention discloses an air-conditioning system, which includes a refrigerant circulation circuit formed by connecting a compressor, an outdoor heat exchanger, a first electronic expansion valve and a first indoor heat exchanger through pipelines, and also includes a bypass heat exchange pipeline , the bypass heat exchange pipeline has an input end and an output end; a second electronic expansion valve, a second indoor heat exchanger and a capillary tube are connected in series on the bypass heat exchange pipeline; the output end of the bypass heat exchange pipeline communicates with On the pipeline between the first electronic expansion valve and the first indoor heat exchanger; the input end of the bypass heat exchange pipeline can be selectively communicated with the pipeline between the outdoor heat exchanger and the compressor or with the outdoor heat exchange The pipeline between the device and the first electronic expansion valve is connected. When the air conditioning system is running in dehumidification, the input end of the bypass heat exchange pipeline is connected with the pipeline between the outdoor heat exchanger and the compressor or with the outdoor heat exchanger and the compressor. The pipes between the first electronic expansion valves are connected to enable the second indoor heat exchanger to operate in heating or cooling.

Description

technical field [0001] The invention relates to the technical field of air conditioning systems, in particular to an air conditioning system and a dehumidification control method. Background technique [0002] Under any temperature conditions, humid air is not good for the human body. In a low-temperature environment, humidity strengthens the conduction of heat by air, causing a large amount of heat loss from the human body, making the human body more vulnerable to cold damage, and prone to rheumatism and bronchitis. In an environment with high temperature, when the relative humidity is too high, it will hinder the heat dissipation of the human body. In addition, the humid environment has adverse effects on patients with tuberculosis, kidney disease, rheumatoid arthritis, chronic low back pain and other diseases. [0003] At present, the dehumidification of the living space is mainly realized through the air conditioning system. When the air conditioning system is in dehum...

Problems solved by technology

[0003] At present, the dehumidification of the living space is mainly realized through the air conditioning system. When the air conditioning system is in dehumidification operation, the indoor heat exchanger operates in cooling mode, and the indoor fan operates at a low speed; however, the existing problems and defects are that during the dehumidification process, the air conditioner The system will also produce a cooling effect to lower the temperature in the space environment, so in order to keep the ambient temperature near the set temperature, the air conditioning system will frequently start and stop the compressor during the dehumidification process. The service life and reliability are greatly affected, and it also leads to large temperature fluctuations in the environment, which greatly affects the user experience and greatly reduces the comfort
