Adjustable load device used for air-conditioning compressor frequency conversion driving module

Abstract

The invention discloses an adjustable load device used for an air-conditioning compressor frequency conversion driving module. The adjustable load device comprises an installation plate. A compressor motor and a power generator are respectively installed on two sides of the installation plate. A first belt pulley is installed on a first output shaft of the compressor motor, a second belt pulley is installed on a second output shaft of the compressor motor, the first belt pulley and the second belt pulley are connected through a triangular belt, and the triangular belt is kept tight. The compressor motor is electrically connected with the air-conditioning compressor frequency conversion driving module. The power generator is electrically connected with a power load network. According to the invention, an adjustable load can be rapidly provided to the air-conditioning compressor frequency conversion driving module, and the problem in the prior art that output power is restricted by indoor and outdoor temperatures in an air-conditioning compressor frequency conversion driving module experiment is solved.

Description

technical field [0001] The invention relates to the technical field of air conditioner reliability test, in particular to an adjustable load device used for an air conditioner compressor variable frequency drive module. Background technique [0002] During the test of the drive module of the air conditioner inverter compressor (the drive module of the air conditioner inverter compressor is realized in the initial prototype stage of the research and development and design of the drive module of the air conditioner inverter compressor, by applying a series of conditions such as high temperature, low temperature, vibration, etc., to observe whether it will work under these conditions A test in which a failure occurs), the evaporator and condenser inside and outside the air conditioner need to be used as loads, when the test is carried out in this way, the output power of the drive module of the air conditioner inverter compressor is restricted by the indoor and outdoor temperatu...

[0002] During the test of the drive module of the air conditioner inverter compressor (the drive module of the air conditioner inverter compressor is realized in the initial prototype stage of the research and development and design of the drive module of the air conditioner inverter compressor, by applying a series of conditions such as high temperature, low temperature, vibration, etc., to observe whether it will work under these conditions A test in which a failure occurs), the evaporator and condenser inside and outside the air conditioner need to be used as loads, when the test is carried out in this way, the output power of the drive module of the air conditioner inverter compressor is restricted by the indoor and outdoor temperature, and cannot be continuously changed and reached The maximum output power cannot test whether the load capacity of the drive module of the air conditioner inverter compressor is the design index, and before each experiment, it is necessary to vacuumize the internal and external units of the air conditioner and add fluorine, which is inefficient and increases additional workload.
