After pipe aluminum fin type heat exchanger 1 is exchanged with the weak solution caloic of wet film heat exchanger 1 (regeneration module) high temperature again after exchanging heat
It is discharged to outdoor, dry return air takes away a large amount of moisture content and heat in weak solution in wet film heat exchanger 1, concentrates solution, and
Further decrease solution temperature.Since Summer Indoor return air temperature is relatively low, humidity is relatively low, if the indoor return air with low temperature is direct
Regeneration, solution regeneration effect can be very poor, and time liquid temperature at this time in wet film heat exchanger 1 is still relatively high, if directly
It returns to after solution tank 9 and is pumped into heat exchanger 1 (effect for serving as condenser) by pumping one 10 (regeneration pumps), pressure will certainly be improved
The condensation temperature of compression system, it is not energy-efficient.So higher time liquid of temperature in wet film heat exchanger 1 is introduced preheating titanium using pipeline
Pipe aluminum fin type heat exchanger 1, utilizes again, on the one hand so that solution temperature further decreases, to reduce compressibility

It is sent to interior after being exchanged with the lower concentrated solution caloic of temperature in wet film heat exchanger 27 (dehumidification module), in wet film heat exchanger 27
Middle concentrated solution absorbs the moisture in air, has killed bacterium, mould, absorbs the impurity such as dust, fresh air is made to obtain
Dehumidifying, cooling and purification, the moisture that solution absorbs are diluted, and the impurity such as dust are filtered by solution strainer, periodic cleaning.By
High in summer outdoor fresh air temperature, humidity is high, if directly dehumidified with the outdoor fresh air of high temperature, solution dehumidification effect can be very poor,
And time liquid temperature at this time in wet film heat exchanger 27 is still relatively low, if (removed by pump 2 12 after being returned directly to solution tank 9
Wet pump) it is pumped into heat exchanger 2 13 (effect for serving as evaporator), the evaporating temperature of compressibility will certainly be reduced, it is not energy-efficient.

Parallel operation 2 13, it is more energy saving to improve the evaporating temperature of compressibility, it kills two birds with one stone.2 12 are pumped dense in solution tank 8
Solution is pumped into the concentrated solution for becoming low temperature in heat exchanger 2 13 with refrigerant heat exchanger, and precooling titanium tube is first delivered to by pipeline
Aluminum fin type heat exchanger 26, then be transported to 27 top spray of wet film heat exchanger and outdoor fresh air dropped back into after caloic exchanges it is molten
Liquid bath 9 mixes, and so completes a dehumidification process cycle.
Table 1 is each state point design parameter in summer Fig. 3
Unit winter operation process described in detail below：
When summer mode turns winter mode, only it need to switch 15 direction of four-way valve, it is very simple and convenient, and can root
According to the comparison of indoor environment temperature and setting wind pushing temperature, automatically switch operational mode.Summer dehumidification module becomes winter humidification
Module, summer regeneration module become winter moisture absorption module, and the condenser that summer uses in compressibility becomes the steaming of use in winter
Device is sent out, the evaporator that summer uses becomes the condenser of use in winter, and summer dehumidifying pump becomes winter humidification pump, summer regeneration pump
Become winter moisture absorption pump, electric expansion valve becomes winter from the positive throttling of summer and reversely throttles.
It is specific as follows：As shown in Figure 2, Figure 4 shows, winter indoor temperature is higher, and the higher return air of humidity is taken out by exhaust fan 4
From, first with precooling titanium tube aluminum fin type heat exchanger 1 heat exchange after again in wet film heat exchanger 1 (moisture absorption module) low temperature it is dense molten
Row absorbs the moisture in return air, is diluted to outdoor, concentrated solution after liquid caloic exchanges.Due to winter indoor return air temperature compared with
Height, humidity is higher, if with the direct moisture absorption of the higher indoor return air of temperature, solution moisture sorption effect can be very poor, and wet film at this time
Time liquid temperature in heat exchanger 1 is still relatively low, if being pumped into compression by pumping one 10 (moisture absorption pumps) after being returned directly to solution tank 9
System heat exchanger 1 (effect for serving as evaporator), will certainly reduce the evaporating temperature of compressibility, not energy-efficient.So sharp
Lower time liquid of temperature in wet film heat exchanger 1 is introduced into precooling titanium tube aluminum fin type heat exchanger 1 with pipeline, is utilized again,
On the one hand so that solution temperature further increases, more energy saving to improve the evaporating temperature of compressibility, another aspect return air

It is sent to interior after being exchanged with the higher weak solution caloic of temperature in wet film heat exchanger 27 (humidification module), in wet film heat exchanger 27
High temperature weak solution is heated to winter dryness air, is humidified, and absorbs the dust in air, has been killed bacterium, mould, has been made
Air is humidified, heated and is purified, and solution releases moisture to air, and solution is concentrated, and the impurity such as dust are by solution mistake
Filter filters, periodic cleaning.Since winter outdoor fresh air temperature is low, humidity is low, if directly humidified with the outdoor fresh air of low temperature,
Solution humidifying effect can be very poor, and time liquid temperature at this time in wet film heat exchanger 27 is relatively high, if being returned directly to solution tank
Compressibility heat exchanger 2 13 (effect for serving as condenser) is pumped by pump 2 12 (humidification pumps) after 9, compression will certainly be improved
The condensation temperature of system, it is not energy-efficient.So the weak solution of high temperature is first introduced preheating titanium tube aluminum fin type heat exchanger using pipeline
26, fresh air is preheated, so that new air temperature is improved, but air is still dry at this time, is unsatisfactory for blasting humidity requirement, and this
When finned heat exchanger 26 export solution temperature it is still higher, concentration is very dilute, can humidify, recycle pipeline solution is drawn
Enter wet film heat exchanger 27, utilize again, caloic on the one hand, which occurs, with pretreated fresh air exchanges, the higher weak solution of temperature
Discharge moisture and heat to dry fresh air in wet film heat exchanger 27, and absorb impurity, so that fresh air further heated, humidified and
Purification is sent into interior after reaching ventilation state point.On the other hand, solution in wet film heat exchanger 27 further by cooling and it is dense
Contracting, returns compressibility heat exchanger 2 13, more energy saving to reduce the condensation temperature of compressibility, kills two birds with one stone.
It pumps 2 12 and weak solution in solution tank is pumped into the weak solution for becoming high temperature in heat exchanger 2 13 with refrigerant heat exchanger, pass through pipe
Road is first delivered to preheating titanium tube aluminum fin type 26 pairs of fresh airs of heat exchanger and preheats, then is transported to 27 top of wet film heat exchanger
Spray carries out dropping back into the mixing of solution tank 9 after caloic exchanges with outdoor fresh air, so completes a humidification cycle.
