The specific embodiment
For going out the architectural feature and the effect of the chemical formula dehumidifier of mouth cooling device to attached regeneration air described in the utility model, further understanding and understanding can be arranged, for an embodiment and conjunction with figs., be described in detail as follows:
At first see also (wherein same member) shown in Figure 2 with the symbolic animal of the birth year of the identical numbering of Fig. 1, the chemical formula dehumidifier that the attached regeneration air of the utility model goes out mouth cooling device consists predominantly of a dehumidification system 10 and a regeneration system 20 forms, wherein, dehumidification system 10 enters room air through filter screen 12 and desuperheating coil 13 coolings by dehumidified air inlet 11, and the air after will being dehumidified by air exhauster 15 by 14 backs, dehumidifying district of desiccant wheel is again discharged by dehumidified air outlet 16; Regenerative system 20 makes regeneration air be entered by regeneration air inlet 21, and through a filter screen 22 and a heat(ing) coil 23,24 backs, renewing zone by desiccant wheel make regeneration air be discharged by regeneration air outlet 26 by another air exhauster 25 again; It is characterized in that:
The regeneration air of regenerative system 20 exports 26 places and is provided with a cooling device 30, this cooling device 30 is included between the screen pack 22 of regenerative system and the heat(ing) coil 23 and is provided with an air-to-air heat exchanger 31, by the regeneration air of regeneration air exhauster 25 sucking-offs after blast pipe 32 is directed at this air-to-air heat exchanger 31, again by just discharging after a cooler 33 coolings; Must be provided with a sensor 34 in the air outlet slit of this cooler 33 in addition, this sensor 34 and a controller 35 electrically connect the control valve 37 on the cooling tube 36 of these controller 35 controlled system coolers 33.
During according to above-mentioned tectonic association, its electric power in the cooling device 30 required consumption of regeneration air outlet 26 is compared as follows with the required consumption electric power of known structure:
When the temperature of air conditioner surroundings is 25 ℃, when relative humidity was 50%RH, atmospheric density was 0.8581M
3/ kg, 13.7 ℃ of dew-point temperatures, enthalpy 50.31KJ/kg, water content 9.9g/kg.
The temperature of outdoor environment is 30 ℃, and when relative humidity was 80%RH, atmospheric density was 0.8886M
3/ kg, enthalpy 85.30KJ/kg, water content 21.6g/kg.
If the processing air quantity of chemical formula dehumidifier is 6000CMH, the air quantity of then regenerating is 2000CMH.
So, general chemical formula dehumidifier is discharged regeneration air and is put when outdoor with airduct, and the cold air load when introducing the equivalent fresh air and entering air conditioner surroundings, be 13.7 ℃ of the dew-point temperatures that earlier fresh air are cooled to air conditioner surroundings, heat temperature raising to 25 ℃ again, the gross energy of its required cooling and heating is:
Cooling capacity, 2000M
3/ HR ÷ 0.8886M
3The KJ/kg=105962KJ/HR=24774Kcal/HR=8.2 ton of refrigeration 11KW of/kg * (85.3-38.221).
Add heat, 2000M
3/ HR ÷ 0.8886M
3The KJ/kg=27209KJ/HR=6361Kcal/HR=7.4KW of/kg * (50.31-38.221).Because
1KJ/HR＝0.2338Kcal/HR
The about 1.34KW of 1 ton of refrigeration power consumption
1KW＝860Kcal/HR
Wastage in bulk or weight electric power is 11+7.4=18.4KW.
When the utility model is set up a cooling device in the regeneration air exit, the cold air of must know load as follows:
For improving the dehumidification rate of chemical formula dehumidifier, one desuperheating coil is set in the humid air porch air that enters desiccant wheel is cooled to 15 ℃, learn that by desiccant wheel performance diagram (as Fig. 3) outlet temperature of then regenerating is 46 ℃, the heat exchanger that one air-air is set in the regeneration air exit can be reduced to outlet temperature 36 ℃, learn that by the desiccant wheel performance diagram desiccant wheel hygroscopic capacity is 7g/kg again, the dehumidifying air quantity is 3 times of the regeneration air quantity, so the air moisture content of regeneration air outlet is 7g/kg * 3+9.9g/kg=30.9g/kg, learn that by air characteristics curve map (as Fig. 4) enthalpy is 115.5KJ/HR, required cooling capacity is
2000M
3/ HR ÷ 0.8581M
3KJ/kg=151940KJ/HR=35524Kcal/HR=11.7 ton of refrigeration=the 15.7KW of/kg * (115.5-50.31).
Can save the general chemical formula dehumidifier (18.4-15.7 ÷ 18.4=14.6%) of electric power and reduce by 14.6% cooling capacity.
Secondly, the regeneration air quantity of general chemical formula dehumidifier is for guaranteeing its dehumidification rate, its regeneration air quantity is all adopted fixedly air quantity, when moist changing load, its exhaust air quantity still remains unchanged, so the required fresh air make up of the blast pipe of this chemical formula dehumidifier can not reduce the magnitude of recruitment of fresh air because of the change of moist load.Yet, the cooling device 30 that the utility model is set up is provided with the size of a control valve 37 with the control amount of cooling water in the cooling tube 36 of its system, when the moist changing load of chemical formula dehumidifier, its regeneration air the air of cooler 33 outlet can with change, the sensor 34 of being located at cooler 33 exits can will detect signal input controller 35, this controller 35 is connected with above-mentioned control valve 37, then control valve 37 can be done the cooling adjustment of appropriateness with the air conditions in cooler 33 exits, can reduce the improper consumption of cooling capacity, reduce electric power required when cooling off, can reach and save the more electric power that consumes.
In sum, the chemical formula dehumidifier that a kind of attached regeneration air provided by the utility model goes out mouth cooling device can not only reach outside the load that reduces air conditioner energy source, and this cooling device can be done the cooling adjustment of appropriateness with the air conditions at cooler outlet place, can reduce the improper consumption of cooling capacity, reach the effect that to save more consumption electric power.
