Cooling and dehumidification system and its control method, air compressor

Abstract

The application provides a cooling and dehumidification system and its control method, and an air compressor. The cooling and dehumidification system is used to cool and dehumidify the air to be treated; the cooling and dehumidification system includes: a heat exchange room and a dehumidification device; the heat exchange room is equipped with Heat exchanger; the heat exchange chamber is used to cool down the air to be treated; the dehumidifier is used to dehumidify the air to be treated. According to the cooling and dehumidification system, its control method, and air compressor of the present application, it is environmentally friendly and can effectively reduce the gas temperature and humidity.

Description

technical field [0001] The application belongs to the technical field of air compressors, and in particular relates to a cooling and dehumidification system, a control method thereof, and an air compressor. Background technique [0002] At present, the bearing suspension stability of the high-speed direct-drive magnetic suspension cooling and dehumidification system has high requirements on the cleanliness and dryness of the intake air. Under the condition of constant pressure and constant speed, the higher the suction temperature, the smaller the relative molecular weight of the gas, the less compression the compressor produces, and the easier it is to surge. Once the surge occurs, the precision of the surge will deteriorate, and the suspended bearing may lose control. At the same time, if the humidity is too high, water droplets will be precipitated during compression, and the impeller will run at high speed for a long time, and the blades will continue to be subjected to...

Problems solved by technology

[0003] However, in areas with cold winter and hot summer, the outside temperature in summer can reach above 35°C, and the relative humidity is between 60% and 90%, which greatly affects the working efficiency of the cooling and dehumidification system.

At present, some scholars have proposed that the pre-cooling treatment of the inlet uses a lithium bromide refrigeration unit to cool the inlet, and in winter, the outside temperature can maintain a low temperature without cooling, and the continuous use of a large amount of refrigerant will cause certain pollution to the environment
