Control circuit of compressor

Abstract

The invention discloses a control circuit of a compressor. The control circuit comprises a main control chip, a wireless connection circuit, a reset circuit, a burning circuit, a driving main controller, a main control drive-by-wire, a compressor connection circuit, a storage module, a display, a control key, a control circuit and a voltage stabilizing module. The compressor is connected with a wireless device through the wireless connection circuit, so that the compressor can be remotely controlled and adjusted, the storage module is arranged so that the compressor can record the operation process, and the reset circuit is arranged so that the compressor can be controlled and adjusted. Therefore, the compressor can be reset and adjusted during operation, and instability of the compressorduring operation is prevented.

Description

technical field [0001] The invention belongs to the technical field of compressors, and in particular relates to a control circuit of a compressor. Background technique [0002] A compressor is a driven fluid machine that elevates low-pressure gas to high-pressure gas, and is the heart of the refrigeration system. It inhales low-temperature and low-pressure refrigerant gas from the suction pipe, drives the piston to compress it through the operation of the motor, and discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle. In this way, the refrigeration cycle of compression→condensation (heat release)→expansion→evaporation (heat absorption) is realized. Compressors are divided into piston compressors, screw compressors, centrifugal compressors, linear compressors, etc. The compressor is regarded as the heart of the refrigeration system, and the special term that best expresses the characteristics of the...

Problems solved by technology

[0003] For example, the control circuit of a DC on-board compressor disclosed by the authorized announcement number CN107181432A, although it realizes the motor commutation without high-frequency switching loss, the loss is minimized, and the voltage added to the three-phase motor line is DC The bus voltage and motor efficiency are maximized, but it does not solve the problem that the existing compressors cannot be remotely controlled and adjusted when they are in use, and it is impossible to record the operation of the compressor and reset the compressor. regulation, etc., for which we propose a compressor control circuit
