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.

Abstract

The invention discloses an optimizer of a dual-compressor air-conditioning system, which is used for regulating the speed of a first-stage compressor, a second-stage compressor and an indoor fan in the dual-compressor air-conditioning system. The optimizer comprises a speed regulation device, an air supply temperature sensor and a controller. The speed regulation device is arranged near a power supply and is used for collecting related information of current and power from the system and sending the information to the controller. The air supply temperature sensor is connected with the indoor fan so as to collect air supply temperature values. The controller is respectively connected and communicated with the speed regulation device and the air supply temperature sensor. The controller judges an operating mode of the system according to information such as the power and current values, the air supply temperature values and the like, and sends a speed command to the speed regulation device so as to regulate the speed. The invention also discloses the dual-compressor air-conditioning system with the optimizer.

Description

technical field [0001] The present invention relates to an air conditioning system, in particular to a dual compressor air conditioning system, especially for but not limited to the following systems: residential air conditioning systems, roof air conditioning systems, residential and commercial air source heat pump systems and water source heat pump systems. Background technique [0002] Dual compressor air conditioning systems are widely used in residential and commercial buildings. A typical dual compressor air conditioning system consists of a compressor, a thermostat, a condenser (evaporator) and an indoor fan. A typical dual-compressor air-conditioning system can maintain a stable room temperature by turning on and off one or more compressors in the two stages. When the system is under low load or the room temperature is lower than the preset temperature value, only the first-stage compressor is turned on. ; When the system load is high or the room temperature is high...
