Compression refrigeration and solution combined gas dehumidifying system

Abstract

The invention discloses compressing type refrigeration and solution compound gas dehumidification system. The compressing type refrigeration system includes compressor, and orderly connected with condenser, throttle valve and evaporator. The solution system includes moisture separator, regenerator, and pump connection. They are independent system. Thus the gas can be treated independently to avoid solution corrosivity for refrigeration system. It has the advantages of simple structure and good moisture extraction effect.

Description

technical field [0001] The invention relates to a gas dehumidification system composed of compression refrigeration and solution. Background technique [0002] In a conventional vapor compression refrigeration system, dehumidification is achieved by reducing the temperature of the cooling coil to below the dew point temperature of the gas. However, under high humidity conditions, this dehumidification method is not efficient, and the resulting indoor hot and humid environment is also uncomfortable. A common practice is to lower the set temperature of the cooling coil, which in turn increases the cooling power consumption. [0003] The principle of solution dehumidification is: the aqueous solution of some salts (such as calcium chloride, lithium chloride) is mixed with salt molecules, so that the concentration of water molecules is reduced, so that the water vapor molecular pressure of the saturated air layer on the surface of the salt water will be reduced. The molecular ...
