The two-stage residual heat recovery type fresh air conditioner-mechanical of the utility model combination indirect evaporative cooling technology, its course of work tool
Body is as follows：
1. the wind system course of work is divided into three summer of extreme sweltering heat, conditioning in Transition Season and winter operating modes, specific works
Process difference is as follows：
(a) extreme hot summer, its course of work are as follows：
Outdoor fresh air forms the fresh air of cleaning after filter A1 filterings；Clean fresh air is steamed indirectly into the first plate-fin
Send out in cooler, flowed in an air passage of plate-fin heat exchanger A2, while indoor low temperature return air is in secondary air duct and water
Temperature reduces after carrying out hot and humid area, the fresh air for precooling cleaning；Fresh air after precooling enters the second plate fin type indirect evaporative
In cooler, temperature is more in secondary air duct of the air passage of plate-fin heat exchanger B5 with moistening and after direct evaporating-cooling
Heat exchange occurs again for low indoor return air, forms the lower fresh air of temperature；The lower fresh air of temperature enters direct evaporating-cooling
It is interior, equal-enthalpy humidifying cooling treatment is carried out at filler 7, if within the summer extremely hot time, when in direct evaporative cooler
Filler 7 when cannot meet that cooling requires, to cold water is led in cold and hot coil pipe 8, for further cooling fresh air, fresh air after cooling
Under the action of pressure fan 9 interior is sent into through air outlet 23.
(b) transition season：
At general hot season, outdoor fresh air forms the fresh air of cleaning after filter A1 filterings；Clean fresh air enters
In first plate fin type indirect evaporative cooler, flowed in an air passage of plate-fin heat exchanger A2, while indoor low temperature return air
In secondary air duct and water carries out temperature reduction after hot and humid area, the fresh air for precooling cleaning；Fresh air after precooling enters the
In two plate fin type indirect evaporative coolers, in secondary air duct of the air passage of plate-fin heat exchanger B5 with moistening and through direct
Heat exchange occurs again for the lower indoor return air of temperature after evaporation cooling, forms the lower fresh air of temperature；The lower fresh air of temperature
Into in direct evaporating-cooling, equal-enthalpy humidifying cooling treatment is carried out at filler 7, forms the cold wind for meeting air-supply condition, cold wind
Under the action of pressure fan 9 interior is sent into through air outlet 23；
In the above process, cold and hot coil pipe 8 is closed, and the air after the processing of filler 7 is under the action of pressure fan 9 through air outlet
23 are sent directly into interior, and indoor return air by plate-fin heat exchanger A2, plate-fin heat exchanger B5 secondary air duct after, in air draft
Under the action of machine 19 outdoor is discharged through exhaust outlet 22.
(c) winter：
Outdoor fresh air forms the fresh air of cleaning after filter A1 filterings；Clean fresh air is steamed indirectly into the first plate-fin
Send out in cooler, flowing and the indoor high temperature return air progress flowed in secondary air duct in an air passage of plate-fin heat exchanger A2
Heat exchange, preheats fresh air, and the secondary air duct of plate-fin heat exchanger B5 keeps drying at this time；Fresh air after preheating enters the second plate-fin
In indirect evaporation cooler, returned in an air passage of plate-fin heat exchanger B5 with the Indoor Thermal flowed in dry secondary air duct
Heat exchange, new air temperature rise, direct evaporative cooler unlatching at this time, for the outdoor fresh air of winter relatively dry occur again for wind
Humidify, the outdoor fresh air after humidification is raised by temperature after cold and hot coil pipe 8, forms the hot-air for meeting air-supply condition, hot-air
It is sent under the action of pressure fan 9 indoor.
2. the water system course of work is divided into three summer of extreme sweltering heat, conditioning in Transition Season and winter operating modes, specific works
Process difference is as follows：
(a) during summer：Periodically clean water is passed through in header tank A17 and header tank B13, and respectively with water pump A16, water
Pump B15 is pulled water out and sent to intermittent water distributor A3, intermittent water distributor B4, by intermittent water distributor A3 by water spray to plate wing
Formula heat exchanger A2, the secondary air duct by intermittent water distributor B4 by water spray to plate-fin heat exchanger B5, in secondary air duct
Form uniform moisture film；Indoor return air enters in the secondary air duct of plate-fin heat exchanger B5 carries out direct evaporating-cooling mistake with moisture film
Journey, the secondary air duct of return air into plate-fin heat exchanger A2 after temperature reduction are interior to carry out direct evaporating-cooling process with moisture film,
Unevaporated water is separately flowed into header tank A17 and header tank B13 along secondary air duct and recycled；During summer sweltering heat weather
Water flowing in direct evaporative cooler and cold and hot coil pipe 8.
(b) transition season：When general hot gas needs cooling, clean water is periodically passed through header tank A17 and is catchmented
In case B13, and pulled water out sent to intermittent water distributor A3, intermittent water distributor B4 with water pump A16, water pump B15 respectively, by
Formula of having a rest water distributor A3 is by water spray to plate-fin heat exchanger A2, by intermittent water distributor B4 by water spray to plate-fin heat exchanger B5
Secondary air duct, uniform moisture film is respectively formed in secondary air duct；Indoor return air enters the secondary air duct of plate-fin heat exchanger B5
It is interior to carry out direct evaporating-cooling process with moisture film, temperature reduce after return air into the secondary air duct of plate-fin heat exchanger A2 with
Moisture film carries out direct evaporating-cooling process, and unevaporated water is separately flowed into header tank A17 and header tank B13 along secondary air duct
Recycle；To water flowing in direct evaporative cooler, cold and hot coil pipe 8 is closed without water flowing at this time.
(c) during winter：Intermittent water distributor A3 and intermittent water distributor B4 are closed, i.e., does not give plate-fin heat exchanger A2 and plate
The secondary air duct water drenching of fin heat exchanger B5, keeps secondary air duct drying, supplies water for direct evaporative cooler, by intermittent water distribution
Device C6 is sprayed, and is to lead to hot water in cold and hot coil pipe 8 to be used to further heat outdoor fresh air for air wetting.
The two-stage residual heat recovery type fresh air conditioner-mechanical of the utility model combination indirect evaporative cooling technology, can meet whole year
Requirement, and indoor section refrigeration duty is undertaken, the consumption of energy can be not only reduced in the process of running, moreover it is possible to make Interior Space
Gas quality is maintained at gratifying level.
