Operation principle：
Precooling：Control module 22 sends out instruction, and Electric air valve 1, Electric air valve 2 18 act, and open indoor air-supply and outdoor
Air exhaust passage, exhaust blower 7, new wind turbine 8 are run in succession；Compressor 1 starts, and four-way valve 1, four-way valve 23 are all failure to actuate, compression
The high temperature and high pressure gas that machine 1 is discharged flows through four-way valve 1 and enters outdoor heat exchanger 4, outdoor to discharge under the action of exhaust blower 7
Air setting heat release；Entered after liquid storage device 9 by check valve 5 15 by connecting copper pipe again and become room temperature into restricting element 10
Low pressure damp steam gets in heat exchanger 5, and be absorbed into indoor fresh air under the action of new wind turbine 8 by check valve 1
Heat after, through four-way valve 1 enter compressor 1；So cycle, and fresh air then realizes cooling due to temperature difference heat release.
Heating：Control module 22 sends out instruction, and Electric air valve 1, Electric air valve 2 18 act, open indoor air inlet and
Outdoor air exhaust passage, exhaust blower 7, new wind turbine 8 are run in succession；Compressor 1 starts, the action commutation of four-way valve 1, four-way valve 23
It is failure to actuate, the high temperature and high pressure gas that compressor 1 is discharged flows through four-way valve 1 and gets in heat exchanger 5, in the effect of new wind turbine 8
It is lower to the fresh air air setting heat release got in；Enter section after entering liquid storage device 9 by check valve 4 14 by connecting copper pipe again
Fluid element 10 becomes Room-temperature low-pressure damp steam, then enters outdoor heat exchanger 4 and under the action of exhaust blower 7 by check valve 2 12
It absorbs after discharging the heat of air outside window, enters compressor 1 through four-way valve 1；So cycle, and fresh air is then due to the temperature difference is absorbed heat
Realize heating.
Dehumidifying：Control module 22 sends out instruction, and Electric air valve 1, Electric air valve 2 18 act, open indoor air inlet and
Outdoor air exhaust passage, exhaust blower 7, new wind turbine 8 are run in succession；Compressor 1 starts, and four-way valve 1 is failure to actuate, four-way valve 23 is dynamic
Make, the high temperature and high pressure gas stream that compressor 1 is discharged is divided into two parts；Most of gas enters outdoor heat exchanger through four-way valve 1
4, to the air setting heat release that discharge is outdoor under the action of outdoor circulating wind machine 7, then check valve 5 15 passed through by connecting copper pipe
Become Room-temperature low-pressure damp steam, then heat exchanger 5 is got in by check valve 1 into restricting element 10 after into liquid storage device 9
And it is absorbed under the action of new wind turbine 8 after the heat of indoor fresh air air and enters compressor 1 through four-way valve 1；
And the small part of gas that compressor 1 is discharged enters dehumidifying reheater 6 after flowing through four-way valve 23, equally in the new wind turbine 8 in room
Under the action of, to have been subjected to 5 processed Cryogenic air of indoor heat exchanger condensation heat release promoted wind pushing temperature to and return air temperature
It is close, it is unlikely to allow people to pass through after not feeling well by connecting pipe and after passing through check valve 3 13 into liquid storage device 9, with being changed from outdoor
Enter restricting element 10 after the liquid refrigerant mixing that hot device 4 flows into；So cycle, removing get in wet in fresh air air
It spends and air blow and return excessive temperature differentials is avoided to cause human body uncomfortable, unit enters standby mode after reaching sets requirement.
Fresh air：Control module 22 sends out instruction, and Electric air valve 1, Electric air valve 2 18 act, and opens new, air draft disengaging
Channel starts new wind turbine 8, exhaust blower 7, and full air exchange pellet 16 is entered after the indoor turbid filtered device 2 20 of wind, outdoor new
After harmful substance of the wind under the action of new wind turbine 8 via Electric air valve 3 18 and in the case where filter device 2 19 acts in removal fresh air
Into full air exchange pellet 16, after carrying out hot and humid area with indoor turbid wind, indoor turbid wind discharges room under the action of exhaust blower 7
Outside, outdoor processed fresh air is then converged after rear and filtered device 3 21 is further processed with indoor circulation wind by new wind turbine
8 are sent into interior, and so cycle is out of service after fresh air reaches setting value.
