Output-power-self-adapting refrigeration compressor control system

Abstract

An output-power-self-adapting refrigeration compressor control system which comprises a refrigeration compressor and a control system body. The refrigeration compressor is provided with a sealed shell. A machine core assembly is arranged in the shell. A motor is arranged on the machine core assembly and is provided with a stator, a rotor and a wire holder. A connection terminal I, a connection terminal VI and a connection terminal VII are arranged on the wire holder. The output-power-self-adapting refrigeration compressor control system is characterized in that the control system body comprises a PLC, a current collection module, a temperature collection module and a low-voltage control circuit; the wire holder is further provided with a connection terminal II, a connection terminal III, a connection terminal IV and a connection terminal V, the PLC is connected with the current collection module, the temperature collection module and the low-voltage control circuit in a communication mode, and the low-voltage control circuit is connected with the refrigeration compressor in a driving mode. The output-power-self-adapting refrigeration compressor control system is low in cost and convenient to operate, intelligent conversion of the three working states of the refrigeration compressor is achieved, the working efficiency of the refrigeration compressor is improved, the overall energy consumption of the refrigeration compressor is reduced, the refrigeration time is shortened, and the refrigeration efficiency is improved.

Description

technical field [0001] The invention relates to a control system of refrigeration equipment, in particular to a refrigeration compressor control system with self-adaptive output power. Background technique [0002] With the continuous advancement of energy conservation and emission reduction, the energy consumption requirements for refrigeration equipment are also continuously increasing. In daily life, as a widely used refrigeration equipment, the reduction of the operating energy consumption of the refrigerator is particularly important for energy saving. In the refrigeration equipment (refrigerator), the small hermetic refrigeration compressor is the heart of the refrigeration work of the whole system, and the working performance of the refrigeration compressor directly affects the refrigeration energy consumption. The existing refrigerating compressor has a closed casing, and a core assembly is housed in the closed casing. On the shell, there are three terminals on the...
