The invention provides a compressor starting device and method and a variable frequency air conditioning system. The device comprises a driver and a heating belt; the driver comprises a power module,a temperature sampling module and a control module; the temperature sampling module is connected with the control module; the control module is connected with the power module; the power module is connected with a first relay and a second relay; one end of the heating belt is connected with the second contact end of the second relay, and the other end of the heating belt is connected with the second contact end of the first relay, and the both ends are jointly connected to a motor of a compressor; the first relay and the second relay are both connected with the control module; according to thedevice, a shell and the motor of the compressor can be heated at the same time, so that the heating efficiency is higher, and the low-temperature starting capacity of the compressor is effectively improved; the system complexity is reduced, so that the control is simpler and safer; and the heating process of the compressor is optimized, and the overall operation reliability and efficiency are improved, so that the power consumption is reduced.
Description
technical field [0001] The invention belongs to the technical field of compressors, and in particular relates to a compressor starting device, a method and an inverter air conditioning system. Background technique [0002] When the compressor is exposed to the low temperature environment for a long time, all the refrigerant in the system may return to the cavity of the compressor, and in the low temperature environment, due to the solidification of the lubricating oil, the starting resistance of the compressor increases, which may cause the compressor to fail to start. stand up. [0003] Existing low-temperature start-up of compressors usually adopts the following two schemes: [0004] (1) Compressor shell heating and temperature monitoring system controlled by the control board (main control board); [0005] (2) The compressor driver preheats the compressor by injecting a controlled current into the compressor stator according to the control command of the main control. ...
