Abstract

The invention discloses a refrigerant oil heating method and device of a compressor and the compressor. The method comprises the steps that historic data for operation of the compressor are stored, specifically, the historic data comprise the start records of the compressor and the environment temperatures, corresponding to the start records, of the compressor; the current environment temperature of the compressor is obtained, and whether to start the compressor or not is determined according to the start record corresponding to the environment temperature, identical with the current environment temperature, in the historic data; and according to the start records, if the compressor is in a starting state at the environment temperature identical with the current environment temperature, it is determined that the compressor is started, and refrigerant oil is heated before the compressor is started. Through the scheme, the defects of long preheating time, low reliability, energy waste and the like in the prior art can be overcome, and the beneficial effects of short preheating time, high reliability and energy conservation are achieved.

Description

technical field

[0001] The invention belongs to the technical field of compressors, in particular to a compressor refrigeration oil heating method, device and compressor, in particular to a screw compressor refrigeration oil heating method based on fuzzy learning or fuzzy control, and a device corresponding to the method , and a compressor having the device. Background technique

[0002] Compressor is a driven fluid machine that raises low-pressure gas to high-pressure gas, and is the heart of the refrigeration system. Refrigeration oil is an important lubricant for the operation of screw refrigeration compressors (that is, screw compressors), which can play the role of lubrication, gap sealing, cooling, taking away particulate impurities, and ensuring the reliable operation of the unit.

[0003] Existing screw chillers all start preheating when the unit is powered on. Regardless of whether the unit is ready to start, it is always on. This process causes useless preheating ...
