Compressor 1, four-way reversing valve 2, second solenoid valve 4, second condenser 5, filter 10, throttling element 11, evaporator 8, four-way reversing valve 2, compressor 1 connected in series through copper pipes Connect to form a refrigeration cycle; compressor 1, four-way reversing valve 2, first solenoid valve 3, first condenser 7, filter 10, throttling element 11, evaporator 8, four-way reversing valve 2, The compressors 1 are connected in series through copper tubes to form a dehumidification cycle. The first solenoid valve and the first condenser and the second solenoid valve and the second condenser are connected in parallel between the four-way reversing valve 2 and the filter 10 . The air outlet 12 and the first air return port 16 are provided at the bottom of the indoor air chamber of the air conditioner body, the fresh air port 15 is provided on the side wall of the fresh air chamber of the body, the air exhaust port 14 is provided at the top, and the second air return port 21 is provided at the bottom. The air conditioner bottom is also provided with a base plate 26, and the base plate is provided with the base plate air return port 23, and the return air cavity 22 is formed between the base plate 26 and the air return port of the indoor air chamber and the fresh air chamber. . Wherein the first air return port 16 is connected with the second air return port 21 through the return air cavity 22 and the bottom plate return air port 23 . The fresh air outlet 15 and the second return air outlet 21 are connected through three ventilation pipes 20, and there is an electric valve 19 in the three ventilation pipes. Through the position switching control of the electric air valve 19, the shared second blower fan 6 can be connected from the new air outlet 15 and the second air outlet respectively. The air return port 21 leads air to the fresh air chamber of the body. An energy-saving lighting lamp 24 is housed at the bottom center of the air conditioner.

As shown in Figure 2 for cooling operation, the indoor air enters the air conditioner through the first air return port 16 after passing through the air return port 23 and the return air cavity 22 of the bottom plate, and is cooled by the evaporator 8, and the cooled air passes through the first condenser 7 Without any change, run through the first fan 9 again, and send it into the room through the air outlet 12 and the base plate air outlet 25. The electric air valve in the fresh air room is turned to the dotted line position (parallel to the second air return port), so that the second air return port is closed, and the outdoor air enters from the fresh air port 15, passes through the second condenser 5 and cools it, and then passes through the second fan 6 , discharged into the room through the air outlet 14. In Fig. 1, when the second electromagnetic valve 4 is opened and the first electromagnetic valve 3 is closed; the AB end of the four-way reversing valve 2 is turned on, and the CD end is turned on. The refrigerant exits the compressor 1 and enters the second condenser 5, where it is cooled by the outdoor air. After being filtered by the filter 10, it is throttled by the throttling element 11, and the throttled liquid refrigerant enters the evaporator 8 to absorb indoor air. The heat returns to the compressor 1, thus completing a refrigeration cycle.

Perform heating operation as shown in Figure 2, after the indoor air passes through the air return port 23 of the bottom plate and the return air cavity 22, it enters the air conditioner through the first return air port 16, is heated by the evaporator 8, and the heated air passes through the first condenser 7 Without any change in the back, run by the first blower fan 9 again, send into indoor through air outlet 12, bottom plate air outlet 25. The electric air valve in the fresh air room is turned to the dotted line position (parallel to the second air return port), so that the second air return port is closed, and the outdoor air enters from the fresh air port 15, passes through the second condenser 5 and heats it, and then passes through the second fan 6 , discharged into the room through the air outlet 14. In Fig. 1, the second solenoid valve 4 is turned on, and the first solenoid valve 3 is turned off; the AD end of the four-way reversing valve 2 is turned on, and the BC end is turned on. The refrigerant exits the compressor and enters the evaporator 8 to heat the indoor air and is throttled by the throttling element 11. After being filtered by the filter 10, the liquid refrigerant enters the second condenser 5 to absorb the heat of the outdoor fresh air and then returns to compression Machine 1, thus completing a heating cycle.

Carry out the dehumidification operation as shown in Figure 2, the air enters the air conditioner from the air return port 16 on the bottom plate, and is cooled by the evaporator 8, the moisture in the air condenses on the evaporator 8, flows into the water accumulation tray 18, and is discharged through the drain hole 17. The cooled air is heated by the first condenser 7, then runs through the first fan 9, and is sent into the room through the air outlet 12 and the bottom plate air outlet 25. The second fan 6 does not start. In Fig. 1, the first solenoid valve 3 is turned on, and the second solenoid valve 4 is turned off; the AB end of the four-way reversing valve 2 is turned on, and the CD end is turned on. The refrigerant goes out of the compressor and enters the first condenser 7 to heat the dehumidified low-temperature indoor air. After being filtered by the filter 10, it is throttled by the throttling element 11, and the liquid refrigerant enters the evaporator 8 to absorb the heat of the indoor air. Then return to compressor 1, thus completing a dehumidification cycle. Therefore, the air conditioner can be used alone as a dehumidifier.

Exhaust air is performed as shown in Figure 2. The electric air valve in the fresh air room is turned to the solid line position (parallel to the fresh air outlet), so that the fresh air outlet is closed. The tuyere 21 enters, then passes through the second blower fan 6, and is exhausted into the room by the air outlet 14, and all the other parts do not operate.
