Embodiment approach 1
[0025] Such as figure 1 As shown, the dual-compressor air conditioning system mainly includes an indoor fan 108, a first-stage compressor 106, and a second-stage compressor 107. The first-stage compressor 106, the second-stage compressor 107, and the indoor fan 108 are respectively It is connected to the first relay 103 , the second relay 104 and the third relay 105 through power lines 111 , 114 , 116 . The first relay 103, the second relay 104, and the third relay 105 can respectively control the start and stop of the first-stage compressor 106, the second-stage compressor 107, and the indoor fan 108 according to instructions.
[0026] The optimizer includes a speed adjustment device 102, a supply air temperature sensor 109, and a controller 110; the speed adjustment device 102 is connected to the power lines 101, 111, 114, 116 of the dual-compressor air conditioning system, and communicated with the controller 110 , the first relay 103, the second relay 104 and the third re...
Embodiment approach 2
[0053] The difference from Embodiment 1 is that the existing thermostat in the dual-compressor air-conditioning system communicates with the first relay 103, the second relay 104, and the third relay 105; the controller 110 communicates with the thermostat; The controller 110 controls the thermostat, and the thermostat is provided with a control program to control the first relay 103, the second relay 104, and the third relay 105, so that the indoor fan 108, the first The stage compressor 106 and the second stage compressor 107 are turned on or off.
