Intelligent management and control equipment for cold and hot joint supply of heating ventilating and air conditioning system and control method thereof

Abstract

The invention discloses intelligent management and control equipment for the cold and hot joint supply of a heating ventilating and air conditioning system and a control method thereof. The intelligent management and control equipment comprises a user side environment data collection system, a user side monitoring system and a heat source side monitoring system. The intelligent management and control equipment realizes the maximum using of clean energy through a modified terminal temperature load prediction algorithm and the lowest energy loss cold and hot quantity equilibrium assignment algorithm, thoroughly solves the problem that the existing system only taking the environment temperature as a basis is inaccurate in load prediction to realize the equilibrium of cold and hot supply and demand, and meanwhile solves the problem of the cold and hot real-time maximum energy efficiency ratio tracking; meanwhile, the equipment can effectively protect external sensors and cold and heat source equipment, and images which are very visual on a touch screen and used for displaying the system, environment and equipment parameters in real time ensure that a user masters the whole joint supply system.

Description

technical field [0001] The invention relates to building energy-saving technology, in particular to an intelligent management and control device for combined cooling and heating supply of an HVAC system and a control method thereof. Background technique [0002] Energy is an important material basis for human survival and development. At present, my country's energy utilization rate is relatively low, and cooling and heating in HVAC are the main energy consumption points of buildings. Achieve energy saving points in HVAC systems. Nowadays, many energy-consuming units choose solar water heating systems, water-based ground-source heat pump systems, etc. to reduce energy consumption, but they face problems such as system instability, excessive manpower investment, and mismatching of cold and hot supplies, which lead to more energy-saving equipment. Energy-consuming equipment. [0003] The cooling and heating control system in the existing market only predicts the deviation val...
