Water-cooling-storage energy-saving central air-conditioning management system

Abstract

The invention discloses a water-cooling-storage energy-saving central air-conditioning management system and relates to the field of central air conditioners. The water-cooling-storage energy-saving central air-conditioning management system comprises a workstation, a machine room system control cabinet and a tail-end area control cabinet, wherein the tail-end area control cabinet is connected with the machine room system control cabinet through a BACNET protocol of an RS485 bus, and the machine room system control cabinet is connected to the workstation through the network. Via central control of the tail end of an air-conditioner area, data of the site and inside the air conditioners can be acquired in real time and fed back to a DDC direct-digital controller in time, and optimal management of the system is realized by synchronous changing as requirements of empirical calculation and tail-end load. The water-cooling-storage energy-saving central air-conditioning management system is provided with four operating modes including direct cooling, water storage cooling, low-temperature water cooling and combined cooling. By means of peak-valley prices, cooling capacity is stored in a low-temperature water manner, stored-water cooling capacity is used during peak power consumption hours, and starting times of a main unit can be reduced as far as possible or less starting is realized, so that resources are saved.

Description

technical field [0001] The invention relates to the field of central air-conditioning, in particular to an energy-saving control system for water-cooled central air-conditioning. Background technique [0002] With the outbreak of the energy crisis, more and more attention has been paid to low-carbon energy conservation. As a vital part of modern building systems, central air-conditioning also accounts for a large proportion of energy consumption. How to improve the power utilization rate of central air-conditioning systems is Problems that need to be solved urgently. [0003] Water-storage central air-conditioning is to transfer the electricity consumption of air-conditioning from the peak period of the day to the trough period at night, balance the load of the urban power grid, and use the excess off-peak power of the power grid at night to continue to run the refrigerator for cooling, store it in the form of low-temperature water, and use it during the day During peak hou...

AI Technical Summary

Problems solved by technology

[0004] Most of the central air conditioners in the prior art achieve the purpose of energy saving through equipment energy saving, which cannot minimize energy consumption, and the running time of the equipment in the central air conditioner is uneven, which will shorten the life of the equipment and cause unnecessary waste
