Those of ordinary skill in the art should understand the specific meaning of the above terms in the present invention according to specific situations.
The air conditioner effectively cooperates with the air conditioner outdoor unit to run through the air conditioner indoor unit and the air conditioner outdoor unit, so that the refrigeration and heating circulation of the air conditioner is completed, and the cold and heat regulation of the indoor temperature is realized.
An air conditioner indoor unit may generally include a casing, an indoor unit heat exchanger, an air supply fan, and a fresh air device. The air conditioner indoor unit may be a floor air conditioner indoor unit. The casing comprises a framework for supporting the fan of the indoor unit and the heat exchanger of the indoor unit, and a housing which is covered on the framework and is provided with an air inlet and an air outlet. Generally, the front side of the casing forms the front panel of the indoor unit and has an air outlet on the front side. Since the structure of the housing of the indoor unit of the air conditioner is well known to those skilled in the art, it will not be described herein.
The indoor unit heat exchanger exchanges heat with air flowing through the indoor unit heat exchanger to change the temperature of the air flowing through the indoor unit heat exchanger. The air supply fan is used for promoting the ambient air entering from the air inlet to flow to the indoor unit heat exchanger and promoting the heat exchange air after the heat exchange of the indoor unit heat exchanger to flow towards the air outlet, so that the heat exchange air is discharged to the working environment of the indoor unit.
The indoor unit heat exchanger is used as a part of a refrigeration system. The refrigeration system can be realized by using a compression refrigeration cycle, and the compression refrigeration cycle realizes heat transfer by using a compression phase change cycle of a refrigerant in a compressor, a condenser, an evaporator and a throttling device. In the air conditioner, the refrigerating system can also be provided with a four-way valve to change the flow direction of the refrigerant, so that the heat exchanger of the indoor unit is used as an evaporator or a condenser to realize the refrigerating or heating function. Since the compression refrigeration cycle of the air conditioner is well known to those skilled in the art, the operation principle and structure thereof will not be described herein.
