Solution dehumidification regeneration subsystem comprises solution dehumidification unit and regeneration of waste liquor unit, wherein solution dehumidification unit is made up of the pump 18 that dehumidifies, dehumidifying core body 16, first liquor box 17 and solution line, and regeneration of waste liquor unit is made up of regenerative pump 21, regeneration core body 19, second liquor box 20 and solution line.
The course of work:
New wind enters solution total heat recovery system, namely core body 9, the 3rd release core body 10, the 4th release core body 11 is discharged by the first release core body 8, second successively, evaporimeter 5 is entered after cool-down dehumidification, enter solution dehumidification core body 16 after further cool-down dehumidification by salt-solution absorption moisture, namely after constant enthalpy dehumidifying, warp sends into indoor by pressure fan 22;
Return air enters solution total heat recovery system via exhaust blower 23, namely reclaim core body 6, second by first successively and reclaim core body 7, enter condenser 3 after warming and humidifying, after heating up further, enter regeneration of waste liquor core body 19, moisture in absorption and regeneration solution, namely drains into outdoor after equal-enthalpy humidifying;
The high temperature and high pressure gas that compressor 1 is discharged enters condenser 3 by cross valve 2, in condenser 3, cool also condensation become subcooled liquid (its liberated heat is taken away by air), evaporimeter 5 is entered again after expansion valve 4 reducing pressure by regulating flow, become superheated steam after the heat of the air of evaporimeter 5 is flow through in absorption to be inhaled in compressor by cross valve 2, thus complete the circulation of refrigerant system;
Solution in solution dehumidification core body 16 enters the first liquor box 17, enters solution dehumidification core body 16 by dehumidifying pump 18; Solution in regeneration of waste liquor core body 19 enters the second liquor box 20, enters regeneration of waste liquor core body 19 by regenerative pump 21.
