Refrigeration control system capable of intelligent scheduling and method thereof

Abstract

A refrigeration control method capable of intelligent scheduling is used for realizing steady operation of a compressor in a refrigeration control system which is composed of a plurality of evaporators, comprising the following steps: current temperature of each evaporator and inlet pressure of the compressor are collected by a temperature sensor and a pressure sensor; according to the collected variation tendency of the inlet pressure, the relationship between overall refrigerating effect Q of the current evaporator and refrigerating effect M according to the output power of the compressor can be obtained; in different conditions of 'when Q>M, Q<M and Q=M', the running state of every evaporator is scheduled by the temperature of the evaporators to adjust the overall refrigerating output of the evaporators or the output power of the compressor, thereby realizing the steady operation of the compressor and achieving optimal energy conversation effect.

Description

technical field [0001] The invention relates to the field of refrigeration, in particular to an intelligently dispatched energy-saving refrigeration control system and method. Background technique [0002] Refrigeration systems are widely used in various fields, such as cold storage, refrigerators, air conditioners, etc. The existing refrigeration systems mainly include condensers, liquid storage tanks, evaporators and compressors. Most fields use a refrigeration control system consisting of multiple evaporators and a set of compressors or compressor units. The refrigerant passes through each evaporator and then aggregates into the same refrigeration pipeline. The compressor and each evaporator are directly connected through the suction pipe. However, the existing control system takes each individual evaporator as the optimal control target, without considering the optimal condition at the compressor end. As the working conditions and the system reach After setting the temp...
