The invention relates to the field of air conditioners, in particular to a detection device for a frequency conversion air-conditioner controller The detection device comprises a detection device body and a load supplying unit, the load supplying unit comprises a compressor, a check valve, a four-way valve, a four-way valve piping component and a heat exchanger shunt, the heat exchanger shunt comprises a condensing unit and an evaporating unit, and the components in the load supplying unit form a complete refrigerating circuit When the controller is detected, loading on the compressor changes constantly according to related operation conditions, so that operation conditions of the frequency conversion controller under different working conditions of the compressor can be truly fed back by the controller connected with the compressor, detection blind spots are greatly reduced, detection effect and efficiency are improved, and risk of returning to factory maintenance due to customer complaint in later period is lowered

Detection device for frequency conversion air-conditioner controller

The utility model discloses a testing tool for an air conditioner controller, which comprises a case, a control circuit board, a display screen, a simulation load, an input regulating switch and a power source switch. The case comprises a case body, a case cover and a panel, wherein a partition board is arranged in the box body and divides the box body into a first lower and a second layer above the first layer. The control circuit board is arranged in the first layer or the second layer, the panel is arranged on the front side of the case body, the display screen, the simulation load, the input regulating switch and the power source switch are arranged on the panel, and the display screen, the simulation load, the input regulating switch and the power source switch are electrically connected with the control circuit board through connection lines. By means of the testing tool for the air conditioner controller, a controller to be tested and a control circuit board to be tested are both arranged in the testing tool. When the testing tool for the air conditioner controller performs the testing, testing personnel and the testing tool are isolated, so that safety of the testing personnel and cleanliness and neatness of a work table top are effectively guaranteed. Additionally, the testing tool for the air conditioner controller has the advantages of high testing efficiency and low testing cost.
