A water-cooled storage central air-conditioning energy-saving management system

Abstract

The invention discloses a water-cooled central air-conditioning energy-saving control system, which relates to the field of central air-conditioning; the system workstation, a machine room system control cabinet and a terminal area control cabinet, the terminal area controller is connected to the machine room system control cabinet through the RS485 bus BACNET protocol, and the machine room The system control cabinet is connected to the workstation through the network. Through the centralized control of the end of the air-conditioning area, real-time collection of on-site and air-conditioning internal data and timely feedback to the DDC controller, combined with empirical calculations and end-load requirements and synchronous changes to achieve optimal management of the system The high-efficiency energy-saving management system of the water storage central air conditioner has four working modes, namely: direct cooling, water storage, low-temperature water cooling and combined cooling. It can be stored in the form of storage, use up the stored water cooling capacity during the peak period of electricity consumption, and reduce or less start-up of the main engine as much as possible, so as to achieve the effect of saving resources.

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
