Unit in summer operational process described in detail below:
As shown in Figure 1, Figure 3, room temperature is lower, and the lower return air of humidity is detached by exhaust fan 4, first and preheating titanium tube
Aluminum fin type heat exchanger 1 exchanges heel row with the weak solution caloic of wet film heat exchanger 1 (regeneration module) high temperature again after exchanging heat
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 into
One step reduces solution temperature.Since Summer Indoor return air temperature is lower, humidity is lower, if directly again with the indoor return air of low temperature
Raw, 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 returned
It is pumped into heat exchanger 1 (effect for serving as condenser) by pumping one 10 (regeneration pumps) after to solution tank 9, compression will certainly be improved
The condensation temperature of system, it is not energy-efficient.So higher time liquid of temperature in wet film heat exchanger 1 is introduced preheating titanium tube using pipeline
Aluminum fin type heat exchanger 1, utilizes again, on the one hand solution temperature is further decreased, to reduce the cold of compressibility
Solidifying temperature, more energy saving, another aspect return air temperature enters back into wet film heat exchanger 1 after being heated up, and it is more preferable to be conducive to solution
Regeneration, kill two birds with one stone.Pumping 1 and weak solution in solution tank 9 is pumped into heat exchanger 1 becomes high with refrigerant heat exchanger
The weak solution of temperature carries out caloic with the indoor return air after preheating by Pipeline transport to one 3 top spray of wet film heat exchanger and exchanges
Preheating titanium tube aluminum fin type heat exchanger 1 is introduced by pipeline again afterwards, preheats that drop back into solution tank 9 after return air mixed using waste heat
It closes, so completes a regenerative process circulation.
Outdoor high temperature high humidity fresh air is detached by breeze fan 8, after first exchanging heat with pre-cooling titanium tube aluminum fin type heat exchanger 26 again
It is sent to interior after exchanging 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, obtains fresh air
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 after being returned directly to solution tank 9 by pump 2 12
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.
So the concentrated solution of low temperature is first introduced pre-cooling titanium tube aluminum fin type heat exchanger 26 using pipeline, fresh air is precooled, new wind-warm syndrome is made
Degree reduces, and 26 surface temperature of finned heat exchanger is less than fresh air dew-point temperature at this time, and the moisture in fresh air can also be with
First condensation a part comes out, and achievees the purpose that in advance to cool down fresh air and pre-dehumidified.The solution that finned heat exchanger 26 exports at this time
Temperature is still lower, and concentration is still very high, still can continue to dehumidify, and recycles pipeline that solution is introduced wet film heat exchanger 27,
It utilizes again, caloic on the one hand occurs again with pretreated fresh air and exchanges, the lower concentrated solution of temperature is in wet film heat exchanger
Continue to absorb the moisture and impurity in fresh air in 27, so that fresh air further dehumidified, cooled down and purify, after reaching ventilation state point
It is sent into interior, on the other hand, solution is further warmed and dilutes in wet film heat exchanger 27, returns the friendship of compressibility heat
Parallel operation 2 13, so that the evaporating temperature of compressibility is improved, it is more energy saving, it kills two birds with one stone.2 12 are pumped dense molten in solution tank 8
Liquid pump is sent in heat exchanger 2 13 concentrated solution for becoming low temperature with refrigerant heat exchanger, and pre-cooling titanium tube aluminium is first delivered to by pipeline
Finned heat exchanger 26, then be transported to 27 top spray of wet film heat exchanger and carry out dropping back into solution after caloic exchanges with outdoor fresh air
Slot 9 mixes, and so completes a dehumidification process circulation.
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 supply air 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.
Specific as follows: as shown in Figure 2, Figure 4 shows, winter room temperature is higher, and the higher return air of humidity is taken out by exhaust fan 4
From, first with pre-cooling 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 the exchange of liquid caloic.Due to winter indoor return air temperature compared with
Height, humidity is higher, if solution moisture absorption can be very poor, and wet film at this time with the direct moisture absorption of the higher indoor return air of temperature
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 pre-cooling titanium tube aluminum fin type heat exchanger 1 with pipeline, is utilized again,
On the one hand solution temperature is further increased, so that the evaporating temperature of compressibility is improved, more energy saving, another aspect return air
Wet film heat exchanger 1 is entered back into after being cooled down, and is conducive to the better moisture absorption of solution, is killed two birds with one stone.1 are pumped in solution tank 9
Concentrated solution is pumped into heat exchanger 1 concentrated solution for becoming low temperature with refrigerant heat exchanger, is exchanged heat by Pipeline transport to wet film
One 3 top spray of device change by pipeline introducing pre-cooling titanium tube aluminum fin type again after caloic exchanges with the indoor return air after pre-cooling
Hot device 1 drops back into the mixing of solution tank 9 after precooling return air using waste cold, so completes a moisture absorption process circulation.
Outdoor low temperature and low humidity fresh air is detached by breeze fan 8, after first exchanging heat with preheating titanium tube aluminum fin type heat exchanger 26 again
It is sent to interior after exchanging 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 filtering, 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, preheat fresh air, improve new air temperature, but at this time air be still it is dry, be 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 occurs with pretreated fresh air and 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, so that the condensation temperature of compressibility is reduced, it is more energy saving, it kills two birds with one stone.
It pumps 2 12 and weak solution in solution tank is pumped into heat exchanger 2 13 weak solution for becoming high temperature with refrigerant heat exchanger, pass through pipe
Road is first delivered to preheating 26 pairs of fresh airs of titanium tube aluminum fin type 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 circulation.

After sub- expansion valve 16 throttles, the refrigerant liquid of low-temp low-pressure is formed, into molten with high temperature in heat exchanger 2 13 (evaporator)
Liquid exchanges heat, and the refrigerant gas for forming low-temp low-pressure enters compressor 14, so completes a compressibility circulation.Into
Solution before condenser is cooled down using the preheating technology of this patent, into condenser after condensing pressure can be made to reduce, together
The solution that sample enters before evaporator is heated up using the pre- refrigeration technique of this patent, into evaporator after evaporating pressure can be made to mention
