Specifically, in one embodiment, the air conditioning apparatus 100 includes a controller for obtaining an operation mode of the air conditioning apparatus 100 and electrically connecting the compressor 20, the first opening/closing door 41 and the second opening/closing door 4. In the embodiment, the condenser 21 is disposed in the first heat exchange air duct 11, the evaporator 22 is disposed in the second heat exchange air duct 12, and when the air conditioning apparatus 100 is in the cooling mode, the controller controls the compressor 20 to operate and controls the first opening/closing door 41 and the second opening/closing door 42 to open; when the air conditioning apparatus 100 is in the heating mode, the controller controls the compressor 20 to operate, and controls the first switching door 41 and the second switching door 42 to be closed; when the air conditioning apparatus 100 is in the dehumidification mode, the controller controls the compressor 20 to operate, and controls the first opening and closing door 41 to be closed and the second opening and closing door 42 to be opened; when the air conditioning apparatus 100 is in the discharge mode, the controller controls the compressor 20 to stop operating, and controls the first opening and closing door 41 to be opened and the second opening and closing door 42 to be closed.
Referring to fig. 1, when the switch device is in the first operating state, the first switch door 41 and the second switch door 42 are both opened, and since the wind resistances of the first ventilation pipeline 53 and the second ventilation pipeline 54 are greater than the wind resistances of the first air outlet pipeline 51 and the second air outlet pipeline 52, most of the indoor airflow flowing out of the first air outlet 33 flows out from the outdoor air outlet 511 through the first air outlet pipeline 51, only a small amount of the airflow will cross the second air outlet pipeline 52, and most of the indoor airflow flowing out of the second air outlet 34 flows into the room through the second air outlet pipeline 52 from the indoor air outlet 521, and only a small amount of the airflow will cross the first air outlet pipeline 51, so that the indoor temperature is reduced under the heat exchange effect of the condenser 21 and the evaporator 22. Referring to fig. 2, when the switch device is in the second working state, the first switch door 41 and the second switch door 42 are both closed, and since the middle portions of the first air outlet pipeline 51 and the second air outlet pipeline 52 are blocked, the indoor air flow flowing out of the first air outlet 33 flows to the indoor air outlet 521 through the first ventilation pipeline 53, and the indoor air flow flowing out of the second air outlet 34 flows to the outdoor air outlet 511 through the second ventilation pipeline 54, and the indoor temperature rises under the heat exchange effect of the condenser 21 and the evaporator 22. Referring to fig. 3, when the switch device is in the third working state, the first switch door 41 is closed, the second switch door 42 is opened, a portion of the indoor airflow flows to the first ventilation pipeline 53 through the first air outlet 33 and flows to the indoor, and another portion of the indoor airflow flows to the indoor through the second air outlet 34 and the second air outlet pipeline 52, so that the constant temperature dehumidification effect is achieved under the action of the evaporator 22 and the condenser 21. Referring to fig. 4, when the switch device is in the fourth operating state, the first switch door 41 is opened, the second switch door 42 is closed, the compressor 20 does not operate, a portion of the indoor airflow flows to the first air outlet pipeline 51 through the first air outlet 33 and is discharged to the outside, and another portion of the indoor airflow flows to the outside through the second air outlet pipeline 54 through the second air outlet 34, so as to achieve the air exhaust effect.
In this embodiment, the wind resistances of the first ventilation pipeline 53 and the second ventilation pipeline 54 are larger than the wind resistances of the first ventilation pipeline 51 and the second ventilation pipeline 52 by the difference setting of the wind resistances of the ventilation pipelines. It is clear in the field that the smaller the pipe diameter of the pipeline, the longer the total length of the pipeline, the more the pipe bends, and the larger the wind resistance, so that the adjustment of the wind resistance of the pipeline can be realized by changing the shape and the material of the pipeline. Since the air flow is selectively directed according to the wind resistance, even if the first and second ventilation openings 61 and 62 are not blocked, most of the air flow flows along the first air outlet duct 51 when the first switching door 41 is opened. The same applies to the second outlet duct 52. Therefore, the switching of the door opening and closing device under four working states can be realized only by arranging the first door opening and closing 41 and the second door opening and closing 42, and the door opening and closing device has better air volume and simple and reliable structure.
Specifically, referring to fig. 1 to 4, the first air outlet pipe 51 and the second air outlet pipe 52 are rigid pipes, such as pipes made of ABS or PC, and the first ventilation pipe 53 and the second ventilation pipe 54 are flexible pipes, such as pipes made of tin foil or aluminum. It is clear to a person skilled in the art that the wind resistance of a rigid pipe is generally smaller than that of a hose, so that the wind resistance of the first vent pipe 53 and the second vent pipe 54 is larger than that of the first vent pipe 51 and the second vent pipe 52 by a simple arrangement.
It can be understood that the air outlet assembly can be disposed inside the casing 10, or outside the casing 10, in an embodiment, the air outlet assembly is detachably disposed outside the casing 10, on one hand, the assembly is convenient, and on the other hand, the casing 10 properly adjusts the installation position of the casing 10 in the room by adjusting the shape and size of the air outlet assembly. This is particularly advantageous for mounting the air conditioning device 100 on the upper side of the ceiling.
It can be understood that when the air conditioning system is in the heating mode, the problems of poor heating effect and slow temperature rise exist. In the dehumidification mode, the evaporator 22 absorbs heat to the air flowing therethrough while dehumidifying, which results in a decrease in the indoor temperature. For this reason, the air conditioning system provided in this embodiment preferably further includes an electric heating device, where the electric heating device is disposed at the air outlet end of the second air outlet pipeline 52, or the second heat exchange air duct 12 is close to the second air outlet 34. When air conditioning system is in heating mode, the air current in indoor side heat transfer wind channel is blowing to indoor, can also heat through electric heater unit, plays quick heating, promotes the effect that heats. When the air conditioning system is in a dehumidification mode, the electric heater heats the cold airflow after moisture absorption and blows the cold airflow into a room, and the constant-temperature dehumidification effect is achieved.
The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structure changes made by the contents of the specification and the drawings under the inventive concept of the present invention, or the direct/indirect application in other related technical fields are included in the patent protection scope of the present invention.
