Heat exchange to room air D, that is, flow through third air heat exchanger 5 refrigerant cooling be used for the first air heat exchanger 10
The cooling and dehumidifying of (at this time as evaporator) acts on, and is then heated up by the room air D of third air heat exchanger 5, then rises
Room air D after temperature is conveyed by exhaust blower 9 again, and the room air D after finally heating up send as air draft E from air draft air outlet 19
Go out to outdoor environment, completes the condensing heat-exchange process of third air heat exchanger 5.In the refrigeration mode, the first electric expansion valve 7
Play throttling action；First solenoid valve 3 and second solenoid valve 8 are additionally operable to adjust the refrigerant stream for flowing through the second air heat exchanger 12
Amount, to which the second air heat exchanger 12 of regulation and control is to the heating amount of mixing wind.
Working method two：When needing heating, such as in cold winter, the present invention starts heating mode, and compressor 1 opens
Dynamic, the first solenoid valve 3 and second solenoid valve 8 are closed, and a interfaces of four-way reversing valve 2 are communicated with c interfaces, b interfaces and d interface phases
It is logical, at this point, the first air heat exchanger 10 is used as condenser, the second air heat exchanger 12 not to work, 5 conduct of third air heat exchanger
The heating circulation process of evaporator, refrigerant is：1 → four-way reversing valve of compressor 2 (a is interfaced to c interfaces) → first air changes
10 → the first electric expansion valve of hot device, 7 → the second electric expansion valve 6 → third air heat exchanger 5 → third, 4 → four-way of solenoid valve
Reversal valve 2 (b is interfaced to d interfaces) → compressor 1.
The course of work of heating mode of the present invention：Outdoor fresh air A enters through fresh air air inlet 18 in air-conditioner set cabinet 14,
After the filtering of first filter 24, mixed with the room air C from return air inlet 16, mixed air is first through the first air
Heat exchanger 10 (being used as condenser at this time) heat temperature raising, is then conveyed by centrifugal blower 11, then filter, connect through the second filter 25
It and flows through the second air heat exchanger 12 (not working at this time), then humidified device 26 humidifies, and last mixing wind B is sent from air outlet 19
Go out, it is ensured that be sent into indoor air and meet fresh air and thermal comfort requirement；Meanwhile room air D enters through air draft air inlet 15
In air exhaust heat exchange babinet 13, third air heat exchanger 5 (being used as evaporator at this time) is first passed around so that the heat of room air D
The refrigerant for flowing through third air heat exchanger 5 is exchanged to, that is, the refrigerant heating for flowing through third air heat exchanger 5 is empty for first
The heat temperature raising of gas heat exchanger 10 (at this time as condenser) acts on, and is then dropped by the room air D of third air heat exchanger 5
Temperature, the room air D after then cooling down are conveyed by exhaust blower 9 again, and the room air D after finally cooling down becomes air draft E from air draft
Air outlet 19 passes out to outdoor environment, completes the evaporation and heat-exchange process of third air heat exchanger 5.In the heating mode, second
Electric expansion valve 6 plays throttling action.
Working method three：When needing dehumidifying, such as " going back to Nan Tian " season in southern area, the present invention start dehumidifying mould
Formula, compressor 1 start, and humidifier 26 is closed, and a interfaces of four-way reversing valve 2 are communicated with b interfaces, and c interfaces are communicated with d interfaces, this
When, the first air heat exchanger 10 is used as evaporator, the second air heat exchanger 12 to be used as heater, 5 conduct of third air heat exchanger
Condenser, the same refrigeration mode of dehumidifying circulation process and the course of work of refrigerant, it is only necessary to by controlling the first air heat exchanger
10 evaporating temperature and refrigerating capacity and the heating amount of the second air heat exchanger 12 are realized.
Working method four：When all-fresh air is run, such as in other periods in addition to above-mentioned season, without refrigeration, heating
And dehumidifying, therefore, close compressor 1 and motorized adjustment air-valve 21.
The course of work of all-fresh air operation of the present invention：Outdoor fresh air A enters air-conditioner set cabinet 14 through fresh air air inlet 18
It is interior, it is filtered first through first filter 24, the first air heat exchanger 10 (not working at this time) is then flowed through, then by centrifugal blower
11 convey, then are filtered through the second filter 25, then flow through the second air heat exchanger 12 (not working at this time) and humidifier 26, most
It is sent out afterwards from air outlet 19, obtains clean fresh air B, it is ensured that be sent into indoor fresh air and meet the requirements；Meanwhile room air D warps
Air draft air inlet 15 enters in air exhaust heat exchange babinet 13, passes through third air heat exchanger 5 (not working at this time) successively, four-way commutates
Valve 2 and compressor 1, are then conveyed by exhaust blower 9, and last air draft E is sent out from air draft air outlet 19.
Wherein, the second air heat exchanger 12 is connected in parallel with the formation of third air heat exchanger 5, makes the present invention in refrigeration mode
When, the second air heat exchanger 12 can rationally utilize the condensation heat of included low-temperature receiver to heat air, the second air heat exchanger 12 and third
Air heat exchanger 5 is connected in series with the formation of the first air heat exchanger 10, makes refrigeration and heating loop reasonable combination.
It should be noted that above-mentioned third solenoid valve 4 is for adjusting the refrigerant stream for flowing through third air heat exchanger 5
Amount, to regulate and control the heating of the heat dissipation capacity and the second air heat exchanger of assistant regulating and controlling 12 of third air heat exchanger 5 to mixing wind
