The specific embodiment

Below in conjunction with accompanying drawing technical scheme of the present invention is described further:

Referring to Fig. 1~3, this fresh air processor comprises: gas-liquid direct contacted spraying modules A~E, solution self-circulating pump 8, inter-stage solution pump 9, plate type heat exchanger 1, air backheating device 10, heat pump (evaporimeter, condenser, compressor, choke valve).This new blower fan is divided into that new wind is handled and solution is regenerated two-layer passage; New wind treatment channel is made up of gas-liquid direct contacted spraying modules A, B, C, and solution regeneration passage is made up of the direct contact modules D of gas-liquid, E.There are plate type heat exchanger 1 and the solution that enters the spray modules A to carry out exchange heat, adopt cooling water to reduce and enter the solution temperature of this module.The evaporimeter 2 of first heat pump is used to reduce the spray solution temperature of module B, condenser 4 be used for heating module E spray solution, reactivation heat is provided.The evaporimeter 3 of second heat pump is used to reduce the spray solution temperature of module C, condenser 5 be used for heating module D spray solution, reactivation heat is provided.Solution can adopt the mode of inter-stage systemic circulation, through spray module C, B, A, D, E, C, realizes the concentrated regeneration of solution and the cyclic process (as shown in Figure 1, 2) of dehumidifying successively; Also can adopt the only mode of the circulation of the module in the heat pump respective stages, as circulating (as shown in Figure 3) between module B, the E and between module C, D.

The purpose of this invention is to provide a kind of do not have indoor exhaust wind can under the situation about utilizing, heat pump driven solution-type fresh air processor group.This fresh air processor group is made up of solution recycle system and heat pump two parts.Solution system is by gas-liquid direct contacted spraying modules A~E (wherein A, B, C are dehumidification module, and D, E are regeneration module), solution self-circulating pump 8, and inter-stage solution pump 9, plate type heat exchanger 1 parts such as grade are formed (seeing Fig. 1~3).Heat pump comprises evaporimeter 2,3, condenser 4,5, compressor 6, choke valve 7 parts such as grade.

Fig. 1 is the operation principle of the new blower fan of a kind of solution-type.The figure cathetus is represented the dehumidification solution of grade interior circulated sprinkling, and dotted line is represented the dehumidification solution that inter-stage flows, and chain-dotted line is represented the refrigeration working medium of heat pump.The upper strata passage of new blower fan is new wind treatment channel, and lower floor is the regeneration air stream passage, be used for the concentrated regeneration of solution.

Analyze the flow process and the state variation situation thereof of air and solution according to Fig. 1.Outdoor new wind contacts with low temperature dehumidification solution at different levels through gas-liquid spray modules A, B, C successively and carries out heat and mass, and newly wind is sent into after by cool-down dehumidification indoor.Adopt the low-temperature receiver cooling of different temperatures to enter the solution of spray module, the solution of modules A adopts cooling water by plate type heat exchanger 1 cooling, the solution of module B cools off by the evaporimeter 2 of first heat pump, and the solution of module C cools off by the evaporimeter 3 of second heat pump.The evaporating temperature of first heat pump and condensation temperature all are higher than the relevant temperature of second heat pump.The inter-stage circulation solution is under the effect of inter-stage solution pump 9, enter module C, B, A, D, E successively and return module C again, the solution concentration that enters module C is the highest, and the solution concentration that flows out from modules A is minimum, and the solution of low concentration enters module D, E and is concentrated and sends into module C again after the regeneration and recycle.The dehumidifying effect that the cold of heat pump evaporimeter 2,3 all is used to reduce solution temperature, improves solution; The heat of condenser 4,5 then is used to provide the heat of solution concentration regeneration.In new blower fan group, use outdoor new wind as regeneration air stream, take away the born again moisture of solution concentration.In module D, E, after outdoor new wind at first enters air backheating device 10 and is preheated, enter module D or E, contact with pyrosol and carry out heat and mass, moisture in the solution enters in the air, directly discharges after the hot wet gas current that module flows out reclaims its heat through air backheating device 10.

Flow process and Fig. 1 of the new blower fan group of the solution-type of Fig. 2 are similar, only are the flow process differences of regeneration air stream, and regeneration air stream at first enters module D, and the wet air-flow of the moisture after heat of absorbent solution enters module E again to be continued to use.In flow process shown in Figure 2, owing to the regeneration air stream humidity that enters module E is higher, thereby the too late system shown in Figure 1 of the effect of solution concentration regeneration, but system flow shown in Figure 2 is comparatively simplified.

Fig. 3 has provided the operation principle of the new blower fan group of solution-type of another kind of form.Solution only circulates in the heat pump of correspondence, rather than as illustrated in figures 1 and 2 between two heat pumps, circulating.Figure 3 shows that the new blower fan group that two heat pumps are formed, gas-liquid spray module B, E and first heat pump (evaporimeter 2, condenser 4, compressor 6, choke valve 7) are one group, and gas-liquid module module C, D and second heat pump (evaporimeter 3, condenser 5, compressor 6, choke valve 7) are one group.The evaporating temperature of second heat pump is lower than the evaporating temperature of first system.New wind is sent into after by cool-down dehumidification indoor successively through gas-liquid spray module B, C, diluted solution enters module E respectively and D concentrates regeneration in this process.The flow process of regeneration air is identical with Fig. 1, regeneration air is entered corresponding gas-liquid spray module respectively and pyrosol contacts after air backheating device 10 preheatings separately after, discharges after the wet air-flow of heat reclaims its heat through air backheating device 10.

In the winter time, can adopt cross valve to realize the conversion of refrigeration, heating condition in the heat pump, thereby realize warming and humidifying processing procedure new wind.The flow process of solution and air and aestival aspect only are that the heat and mass direction of the two is opposite together.
