The full heat recovery units of at least one solution-type is made up of the wet exchange of one group of gas-liquid direct contact heat core body, and each group heat exchange core body is connected with a solution circulation pump and supporting solution circulation line thereof;
At least one solution dehumidification unit is composed in series by at least one heat exchange core body, and each heat exchange core body all is connected with a solution circulation pump and supporting solution circulation line thereof;
At least one solution regeneration unit is composed in series by at least one heat exchange core body, and each heat exchange core body all is connected with a solution circulation pump and supporting solution circulation line thereof;
The serial connection passage that new wind constitutes through the wet exchange of the heat core body of assisting dehumidifying surface cooler coil pipe and the full heat recovery units of solution-type, the solution dehumidification unit of flowing through is again sent into indoor; Return air is discharged through the solution regeneration unit through the wet exchange of another heat core body of the full heat recovery units of solution-type again; One cover solution circulation line is arranged between each said solution dehumidification unit core body and the said regeneration unit core body, be used for moisture exchange between Dehumidifying element and regeneration unit, with the concentration of control dehumidification solution.
Further, as preferred version, said auxiliary dehumidifying surface cooler coil pipe is positioned at the rear end of full heat recovery units, the front end of Dehumidifying element.
Because the surface cooler of auxiliary dehumidification by condensation is positioned at the front end of solution dehumidification unit; Finally sending into indoor air directly contacts with salting liquid through heat exchange core body; Salting liquid has the effect of sterilization, dedusting, purification to new wind, helps improving indoor air quality and personnel's health.
Further, as preferred version, said auxiliary dehumidifying surface cooler coil pipe is positioned at the front end of new wind inlet, the full heat recovery units of solution-type.
Further; As preferred version; Also comprise the heat pump refrigerating system, said heat pump refrigerating system comprises at least one compressor, the evaporimeter identical with Dehumidifying element heat exchange core body quantity, condenser, at least one expansion valve identical with regeneration unit heat exchange core body quantity, and the outlet of said evaporimeter connects the inlet of said compressor; The outlet of said compressor is connected to the inlet of said condenser; The outlet of said condenser is connected to the inlet of said expansion valve, and the outlet of said expansion valve is connected to the inlet of said evaporimeter, thereby constitutes heat pump refrigerating systemic circulation loop.
Further, as preferred version, said regeneration unit also comprises water compensating valve, is used to regulate the regeneration unit solution concentration.
Owing to adopt the fresh air dehumidification unit utilize the combined type dehumidification mode that dehumidification by condensation combines with solution dehumidification; Utilize high temperature cold water as auxiliary dehumidifying low-temperature receiver; The Energy Efficiency Ratio of high temperature cold water unit (COP) is up to 7.5～9.2; Higher more than 50% than common handpiece Water Chilling Units (COP is about 5.0), so the dehumidification by condensation process efficiency of the utility model is higher; In addition, owing to adopted the full recuperation of heat of air draft, can further reduce new wind and handle energy consumption, and the mode of solution dehumidification need not solution is cooled to below the air dew point temperature, only need cool to get final product about 20 ℃, so the Energy Efficiency Ratio of heat pump refrigerating system is higher.Can know that amid all these factors the dehumidification process Energy Efficiency Ratio of the utility model is higher, more energy-conservation.
