The gaseous refrigerant is returned to the compressor for further compression to continue the cycle for refrigeration. During heating, the gaseous refrigerant is pressurized by the compressor to become high-temperature high-pressure gas, the high-temperature high-pressure gas enters the second heat exchanger, the gas is liquefied and released heat through condensation to become liquid, and meanwhile, indoor air is heated, so that the purpose of increasing the indoor temperature is achieved. The liquefied liquid refrigerant enters the first heat exchanger, evaporates, vaporizes and absorbs heat to become gas. The refrigerant that has become gas enters the compressor again and starts the next cycle to continue the cycle for heating.

The first valve 122 may be, for example, a solenoid valve.
Here, the gas-liquid separating device 121 may be, for example, in communication with the water jacket 113 in the outdoor unit 110 through the second pipeline 130, and the gas-liquid mixed liquid to be separated by the gas-liquid separating device 121 may be the liquid in the water jacket 113 that absorbs the waste heat of the compressor 112. In order to facilitate that the liquid in the liquid receiving tray 111 can flow into the water jacket 113 first and then into the gas-liquid separating device 121, a liquid pump 140 for pumping the liquid in the liquid receiving tray 111 can be arranged in the second pipeline 130, for example.
The air duct 123 may include an air outlet and an air return outlet, for example, cold air or hot air flows into the indoor unit through the air outlet, and air in the indoor unit flows into the air duct through the air return outlet and is discharged out of the indoor unit through a capillary tube between the indoor unit and the outdoor unit. In order to facilitate determining whether the steam in the gas-liquid separation device needs to flow into the room to increase the humidity of the indoor environment, the inner unit 120 may further include, for example, a first sensor 124, where the first sensor 124 may be, for example, a humidity sensor, and is disposed at a return air inlet of the air duct 123, and is used for detecting the humidity of the indoor environment by detecting the humidity of the return air. Accordingly, the first valve 122 may be configured to, for example: when the humidity of the return air detected by the first sensor 124 is lower than a predetermined humidity, the first valve 122 is opened to communicate the air-liquid separator 121 with the air duct 123, so that the steam in the air-liquid separator 121 flows into the room to increase the indoor humidity. The predetermined humidity may be, for example, any value of 20% to 40%. According to an embodiment of the present disclosure, the predetermined humidity may also be set according to actual requirements, for example. For example, the air conditioning system 100 may be provided with a humidity setting function, and a predetermined humidity is set by a user setting the air conditioning system 100.

Then, it is determined whether the indoor relative humidity is less than 40%, and if the indoor relative humidity is less than 40%, it indicates that the indoor humidity is within an angle, and the indoor environment needs to be humidified, so that the first water level of the condensed water received in the liquid receiving tray 11 is measured by the first water level sensor (i.e., the liquid level in the liquid receiving tray 111 is measured by the third sensor 116). And then judging whether the first water level is greater than a preset water level (namely a preset liquid level), and if the first water level is not greater than the preset water level, periodically measuring the first water level until the first water level is greater than the preset water level. If the first water level is higher than the preset water level, the water pump (liquid pump 140) is turned on to pump the condensed water in the liquid receiving tray 111 into the gas-liquid separation device 121. Then, a second water level (the liquid level in the gas-liquid separation device 121) is measured by using a second water level sensor (i.e., the second sensor 126), and whether the second water level is higher than a low threshold (for example, a water level corresponding to the position of the electric heating device 129) is determined. And if the second water level is not greater than the low threshold, returning to detect the second water level again until the second water level is greater than the low threshold. If the second water level is not lower than the low threshold, it is determined whether the second water level is greater than the high threshold (e.g., may be a water level corresponding to the location of the disinfection device 125). If the second water level is higher than the high threshold, the solenoid valve 1 (the second valve 127) is opened to drain the excessive condensed water through the drain pipe 128, and if the second water level is not higher than the high threshold, the solenoid valve 1 is closed, and the battery valve 2 (the first valve 122) is opened to allow the steam to flow into the room through the air duct to humidify the indoor environment.
After the cell valve 2 is opened for a certain period of time (for example, 10min), the relative humidity in the room is obtained again from the humidity of the return air detected by the humidity sensor, and if the relative humidity in the room reaches 40%, the humidification is terminated, and the cell valve 2 is closed. If the indoor relative humidity is still less than 40%, the detection is performed again after a certain period of time, and if the indoor relative humidity obtained by three consecutive detections does not reach 40%, the electric heating device 129 is turned on to increase the steam content in the gas-liquid separation device 121. And after a certain time after turning on the electric heating device 129, the relative humidity in the room is measured again until the relative humidity in the room reaches 40%.
In summary, according to the air conditioning system and the control method of the air conditioning system in the embodiments of the present invention, the automatic improvement of the indoor humidity can be achieved by using the condensed water, so that the comfort level of the environment where the air conditioner is located when the air conditioner is used is improved, and the user experience is improved. Through utilizing the comdenstion water, not only can solve when opening the air conditioner winter, the problem that outer quick-witted department condensate water freezes or the random flow, can also reduce the frosting volume of outer machine to a certain extent, the water economy resource. Moreover, because the water jacket suction gas-liquid separation equipment of compressor is located through the cover to the comdenstion water, consequently can use this comdenstion water to cool off the compressor to can reduce the operating temperature of compressor under abominable operating mode to a certain extent, reduce the risk that the compressor damaged.
Although the present invention has been disclosed above, the scope of the present invention is not limited thereto. Various changes and modifications may be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
