The following embodiments of the present invention
Embodiment 1, the indoor unit controller 8 of the present invention is set in the summer sleeping mode;
the electric air valve 4 at the air return inlet is closed, the fan 1 stops running, the electronic expansion valve 9 is opened, liquid low-temperature refrigerant enters the fin heat exchanger 7 from the VRV outdoor unit 20 through the refrigerant copper pipe 13 to condense and dehumidify the entering fresh air, and the superheated gaseous refrigerant after heat absorption returns to the VRV outdoor unit 20. The fresh air blower 14 sends out outdoor fresh air from a fresh air supply port 15, the fresh air is sent to a fresh air inlet 3 of an indoor unit through a fresh air supply pipe 16 and enters the air return box 2, the fresh air is condensed and dehumidified through the fin heat exchanger 7 under the residual pressure action of the fresh air blower, and the dehumidified fresh air is sent to the indoor through an air supply port 6. Therefore, the dehumidifying device can dehumidify the outdoor fresh air and send the dehumidified fresh air to the indoor, reduce the humidity of the indoor air and improve the freshness and cleanliness of the indoor air. The indoor unit controller 8 can set a required humidity interval, for example, 60-65%, when the indoor humidity is higher than the upper limit of the set humidity interval, the indoor unit controller 8 opens the electronic expansion valve 9, so that the low-temperature refrigerant enters the fin heat exchanger 7 to dehumidify the fresh air entering the room, and the purpose of reducing the indoor humidity is achieved; when the humidity is lower than the lower limit of the set humidity interval, the electronic expansion valve 9 can reduce the opening degree, so that the dehumidification degree of fresh air entering the room is weakened, the indoor humidity can be gradually increased to a set value, and the indoor humidity is kept in the set humidity interval. The fresh air volume is generally used for ventilating indoor air once in an hour, so when fresh air is dehumidified, the indoor relative humidity can be kept in a certain humidity range, such as 60% -65%, the fresh air volume is small, the indoor temperature cannot be reduced too much, the indoor temperature can be maintained at about 28 ℃ in summer, the VRV indoor unit fan does not operate, noise is avoided, and the indoor environment with the relative humidity of 60% -65% and the room temperature of about 28 ℃ is particularly suitable for sleeping.

The indoor unit controller 8 incorporates a humidity sensor and a temperature sensor, and optionally, a PM2.5 sensor and a VOC sensor. Embodiment 2, when the indoor unit controller 8 is set in the cooling mode;
when the indoor unit controller 8 is set in a refrigeration mode, the air return port electric air valve 4 is opened, the fan 1 runs, the electronic expansion valve 9 is opened, outdoor fresh air enters the air return box 2 and is mixed with indoor return air and then passes through the finned heat exchanger 7, and low-temperature refrigerant enters the finned heat exchanger 7 to freeze the entering mixed air and then is sent into a room, so that refrigeration is realized, the outdoor fresh air is sent into the room, and the freshness and cleanliness of the indoor air are improved.
Embodiment 3, when indoor set controller 8 sets for the mode of heating, return air inlet electric air valve 4 is opened, and fan 1 operates, and electronic expansion valve 9 is opened, and outdoor new trend gets into return air case 2 and indoor return air and mixes the back and passes through finned heat exchanger 7, and the high temperature refrigerant gets into finned heat exchanger 7 and sends into indoor after heating the mixed wind that gets into to realized heating, sent outdoor new trend indoor simultaneously, improved the new freshness and the cleanliness factor of room air.
In embodiment 4, when the indoor unit controller 8 is set in the winter sleep mode, the electric air valve 4 at the air return port is closed, the fan 1 does not operate, the electronic expansion valve 9 is opened, a high-temperature refrigerant enters the finned heat exchanger 7, and outdoor fresh air enters the air return box 2 under the action of residual air pressure supplied by the fresh air fan 14, is heated by the finned heat exchanger 7, and is then sent into the room. Optionally, if the indoor unit controller 8 detects that the room temperature is lower than 18 degrees (the temperature can be flexibly set), the return air inlet electric air valve 4 is opened, the fan 1 is automatically set to operate at ultra-low air speed and ultra-low noise until the room temperature is lower than 18 degrees, the fan stops operating, and the return air inlet electric air valve 4 is closed.
Embodiment 5, set up in new trend ventilation mode when indoor set controller 8, return air inlet electric air valve 4 closes, fan 1 stops, and electronic expansion valve 9 closes, and the refrigerant can't get into finned heat exchanger 7 so does not heat or refrigerate or dehumidify the new trend, and outdoor new trend gets into return air case 2, and the new trend is sent into indoorly under new fan residual pressure effect to realized ventilation to indoorly, improved the new freshness and the cleanliness factor of room air.
In a preferred but nonlimiting embodiment of the present invention, the fresh air inlet 3 has an electric air valve to supply and close fresh air. The electric damper is controlled by the indoor unit controller 8.
In a preferred but non-limiting embodiment of the present invention, the indoor unit controller 8 is connected to the indoor unit electric control board 10 through the indoor unit communication line 11 to control the operation of the indoor unit, and the indoor unit electric control board 10 controls the operation of the VRV outdoor unit 20 through the outdoor unit communication line 12.
In the present invention, referring to fig. 1, a reference numeral 11 is an indoor unit communication line; the label 12 is an outdoor unit communication line; reference numeral 5 is a condensate pan.
The above description is directed to the preferred embodiment of the present invention.
