Energy efficiency cooperative regulation system for air energy extraction process

Abstract

The invention relates to the technical field of energy-saving air conditioners, and discloses an energy efficiency collaborative regulation system for an air energy extraction process, which comprises the following steps: a working condition parameter monitoring module obtains an electronic expansion valve opening instruction sequence and a compressor exhaust pressure sequence; the dynamic response extraction module is used for calculating first-order derivatives of the opening instruction and the exhaust pressure relative to the sampling time and determining an adjusting gradient vector and a response gradient vector; the circulation time delay decoupling module locks the refrigerant circulation lag amount by using a discrete cross-correlation function; according to the energy efficiency cooperative adjustment system and method, thermodynamic response dislocation caused by refrigerant mass flow transfer time lag is eliminated, air suction superheat degree oscillation is restrained, the energy extraction efficiency is improved, the energy efficiency is improved, and the energy efficiency is improved. And hardware-free defrosting identification is realized in cooperation with a virtual perception mechanism.
