An ice storage central air-conditioning energy-saving management system

Abstract

The invention discloses an ice-storage central air-conditioning energy-saving control system, which relates to the field of central air-conditioning; the system includes a workstation, a machine room system control cabinet and an end area control cabinet, and collects field and air-conditioning internal data in real time through centralized control of the end of the air-conditioning area And feedback to the DDC controller in time, the DDC controller changes synchronously with the demand of the terminal load to realize the optimal management of the terminal; the high-efficiency energy-saving management system of the ice storage central air conditioner has four working modes, namely: direct cooling, storage Ice, ice-melting refrigeration and combined cooling, this invention utilizes the peak and valley electricity prices at night to store the cooling capacity in the form of ice, use up the stored ice cooling capacity during the peak period of electricity consumption, and reduce or less start-up of the host as much as possible , can achieve the effect of saving resources; through intelligent control, optimize program selection, optimize program selection, ensure the balanced operation of each equipment, and greatly improve the service life of the equipment.

Description

technical field [0001] The invention relates to the field of central air-conditioning, in particular to an ice-storage central air-conditioning energy-saving control system. 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] Ice-storage central air-conditioning is to transfer the electricity consumption of air-conditioning from the daytime peak period to the night-time trough period, balance the load of the urban power grid, and use the excess off-peak power of the night power grid to continue to operate the refrigerator for cooling, store it in the form of ice, and use it during the daytime peak power consumption When the ice ...

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
