After being exchanged heat by interstage flow heat exchanger, dehumidification solution flows into the liquid reserve tank of regeneration, and actified solution flows into the liquid reserve tank of dehumidifying.
The condensed water of straight swollen surface cooler is directly discharged into the actified solution of the first system.The liquid reserve tank of two-stage regeneration unit is used
Communicating pipe connects, and maintains both sides liquid level equilibrium.
The utility model additionally provides a kind of air conditioner, including solution dehumidification unit, and solution dehumidification unit is above-mentioned molten
Liquid dehumidifying unit.
As can be seen from the above description, the utility model the above embodiments realize following technique effect：
Solution dehumidification unit of the present utility model realizes the dehumidifying to air dewetting by multilevel heat pump system, wherein, it is more
Level heat pump includes regeneration unit, the liquid reserve tank connection of the regeneration unit of adjacent two-stage heat pump.Specifically dehumidifying
During, the first heat pump 10 by the first regeneration unit 11 and surface cooler 12 to air dewetting, wherein, surface cooler 12 is to sky
Gas carries out cool-down dehumidification, and the first regeneration unit 11 includes the first spray pipeline 111, height is realized by the first spray pipeline 111
The actified solution of temperature sprays in atmosphere, and into air, actified solution concentration uprises the moisture evaporation in solution.In addition, this reality
With new by the way that the liquid reserve tank of surface cooler 12 is connected with the liquid reserve tank of the first regeneration unit 11, can make cold in surface cooler 12
Condensate is flowed into the liquid reserve tank of the first regeneration unit 11, reduces actified solution concentration with this, arrangement above can reduce first again
The extraneous rate of water make-up of raw unit 11, but also can solve the problems, such as condensed water elimination.
In the present embodiment, Dehumidifying element is replaced by using surface cooler 12, and retains the first regeneration unit 11, formed new
Heat pump, the heat pump can avoid the high temperature regeneration solution in the regeneration unit of the prior art because of heat pump
With in Dehumidifying element low temperature dehumidification solution constantly exchange and caused by loss of refrigeration capacity, so as to solve solution of the prior art
The problem of loss of refrigeration capacity of dehumidifying unit is larger.
Solution dehumidification unit of the present utility model, because wind pushing temperature is high, relative humidity is low, and thermo-compression evaporation temperature is colder than table
The system of dehumidifying is much higher, therefore heat pump Energy Efficiency Ratio is higher.In the utility model, first order dehumidification system removes using table is cold
Wet mode, because inlet air temperature is higher, it is also possible to obtain higher evaporating temperature.Condensed water is directly drained simultaneously,
It need not be drained by way of interstage flow, there is no an interstage flow heat loss, system heat loss is small.In the first dehumidification system, because
It is the straight swollen cold form of table for evaporator, without dehumidification solution, actified solution concentration is unrestricted, more moisturizing can dilute,
Air draft relative humidity is high, and temperature is low, and compared with original form, the temperature of actified solution is lower, the condensation temperature of the first system
Lower, heat pump power consumption is smaller.
Preferred embodiment of the present utility model is the foregoing is only, is not limited to the utility model, for this
For the technical staff in field, the utility model can have various modifications and variations.It is all in the spirit and principles of the utility model
Within, any modification, equivalent substitution and improvements made etc., it should be included within the scope of protection of the utility model.
