Abstract

The invention relates to a control device and method of a frequency converter of an air conditioner system. According to the control device of the frequency converter of the air conditioner system, the frequency converter is suitable for providing electricity for a motor of a compressor of the air conditioner system to enable the motor to rotate, the control device comprises a determination unit and a control unit, the determination unit is configured to determine the current value range corresponding to the current rotation speed of the motor of the compressor based on the corresponding relationship between the rotation speed of the motor of the compressor and the valve range of the parameter representing the input or output of the motor, the control unit is configured to control the frequency converter to provide electricity for the motor based on the position of the current value of the parameter relative to the current value range so as to protect the compressor. The control device and method can protect the compressor, and it is guaranteed that the compressor operates within a safe range.

Description

technical field [0001] The present disclosure generally relates to a housing system, and in particular, relates to a control device and method for a frequency converter of an air conditioning system. Background technique [0002] The air conditioning system is a common temperature regulation and temperature control system. Compressors, such as scroll compressors, are an essential component of air conditioning systems. The scroll compressor has the characteristics of high efficiency, low noise and stable operation. The compressor sucks low-temperature and low-pressure refrigerant gas from the suction port, compresses the sucked refrigerant gas through the motor, and discharges high-temperature and high-pressure refrigerant gas to the exhaust port. [0003] In situations such as motor running overload, damaged motor, refrigerant leakage, excess refrigerant, contamination of system loops by foreign matter, etc., the compressor will be in failure mode. [0004] Additionally, ...
