Abstract

The invention discloses an energy-saving management system for a central air conditioner, and relates to the field of central air conditioning. The system comprises a work station, a machine room system control cabinet and an end area control cabinet; the end area control cabinet is connected to the machine room system control cabinet through a BACNET (Building Automation Control Network) protocol of an RS485(recommend standard) bus; the machine room system control cabinet is connected to the work station through a network; data in the field or in the air conditioner are acquired in real time and are fed back to a DDC (Direct Digital Control) controller by performing centralized control on the end of an air conditioning area; the optimal management of the end is realized by synchronous change of the DDC controller along with the requirement of an end load. According to the energy-saving management system for the central air conditioner, the energy consumption of the air conditioner is reduced to the great extent, and the effects of saving energy and reducing emission are achieved by adopting system energy saving; the balanced operating of each piece of equipment is guaranteed and the service life of each piece of the equipment is greatly prolonged by intelligent control and optimizing program selection.

Description

technical field [0001] The invention relates to the field of central air-conditioning, in particular to a central air-conditioning energy-saving management 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] 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. Contents of the invention [0004] The invention provides a central air-conditioning energy-saving...
