Problems solved by technology
[0007] Since the air is discharged through the same discharge port, for a small-capacity compressor, the discharged air volume is too much to exceed the required air volume, so the temperature of the discharged air rises and the cooling effect does not reach the user's comfortable body temperature and reduces the dehumidification effect.
[0008] Moreover, the operation mode of the compressor can only be controlled into two stages, and the cooling effect can only be utilized by 100% or 40%, so it cannot adapt to the change of the indoor load or the cooling effect actively selected by the user, and when the cooling effect of 100% is not required Also running two compressors at the same time, the increase in power consumption is a problem

Embodiment Construction
[0041] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0042] Such as image 3 As shown, the three-side discharge type air conditioner according to the embodiment of the present invention includes: a box-shaped main unit 10; a heat exchanger 11 for heat exchange arranged inside the main unit 10; fan12.
[0043] The lower parts of the two sides of the host computer 10 respectively form side suction ports 13 for sucking indoor air.
[0044] Two side upper parts of the main engine 10 and the front of the main engine 10 are respectively formed with side discharge ports 14a and 14b and a front discharge port 15 for discharging conditioned air indoors by the exhaust fan 12 .
[0045]The side discharge ports 14a and 14b are provided with side blades 16a and 16b for opening and closing the side discharge ports 14a and 14b, and stepping motors 18a and 18b for rotating the side blades 16a and 16b. The stepping motors 18a...

The present invention relates to an air-conditioner and its controlling method, especially three-stage operation for controlling two compressors, so as to improve application scope of refrigerating capacity and reduce power consumption. The present invention makes refrigerating capacity clear according to the operation method of compressor to opening air outlet separately. The present invention can prevent discharged air temperature from increasing by decreasing air discharge rate when decreasing refrigerating capacity caused by changing compressor operation method. In addition, the present invention changes the compressor operation method in order to increase and decrease refrigerating capacity to decrease air discharge rate, and open and close air outlet with a certain time difference, thus can decrease air discharged noise of air outlet. Therefore, the present invention provides an air-conditioner controlling method, the air-conditioner comprises at least a compressor capable of changing refrigerant capacity and multiple outlets and indoor fan, its controlling method is based on changeable refrigerant capacity to process multiple operation methods, in operation to judge whetherinputting operation method transform information, if inputting operation method transform information, then decreasing the speed of the said indoor fan, and opening or closing stipulated beforehand atleast a outlet according to operation method transformation.
Description
technical field [0001] The invention relates to an air conditioner, in particular to an air conditioner which has two compressors and combines the functions of the two compressors to perform cooling operation suitable for indoor environments and a control method thereof. Background technique [0002] Usually, such as figure 1 As shown, the indoor unit of the air conditioner includes: an air outlet 2 formed on the upper end of the indoor unit, used to discharge the air cooled by heat exchange in the evaporator (not shown); 3. It is used to display the running status of the air conditioner. [0003] Recently, by using a plurality of compressors with different capacities, it is possible to change the refrigerant compression capacity according to the cooling and heating load, thereby achieving optimum cooling and heating efficiency. [0004] Typically, systems using such multiple compressors employ two fixed-speed compressors designed to have different capacities. That is, wh...
