Energy-saving control method and energy-saving control system for energy consumption track of central air conditioner

Abstract

The invention provides an energy-saving control method for the energy-saving track of a central air conditioner. The energy-saving control method comprises the following steps of step A: determining the refrigerating quantity output outputted by a refrigerating host; step B: determining the load demanded quantity of each tail-end device in the use environment and setting preset output refrigerating capacity of refrigerating host equipment according to the load demanded quantity of each tail-end device; step C: starting the tail-end devices and determining actual output refrigerating capacities of the tail-end devices; step D: adjusting the actual output refrigerating capacities of the refrigerating host according to the load quantities of the tail-end devices and enabling the load quantities of the tail-end devices to tend to be consistent with the preset output refrigerating capacity of the refrigerating host; step E: ending the period and closing the tail-end devices. According to the energy-saving control method provided by the invention, the deviation of refrigerating capacity supply of chilled water is mended and adjusted by the computer according to the change track of the tail-end load, and the output refrigerating capacities in the system are accurately adjusted under various load conditions of the tail end, and the effects of saving energy and reducing emission are achieved. The invention also discloses an energy-saving control system for the energy consumption track of the central air conditioner.

Description

technical field [0001] The invention relates to an energy-saving control method and system for central air-conditioning energy consumption trajectory. Background technique [0002] With the development of science and technology and the improvement of people's living standards, central air-conditioning has been more and more widely used. In all kinds of buildings, the central air-conditioning system has become one of the important symbols of modern building technology, and it is an indispensable and important infrastructure for modern buildings to create a comfortable and efficient working and living environment. But central air-conditioning is the equipment with the largest energy consumption in buildings. While it brings us a comfortable air-conditioning environment, it also brings huge energy consumption. [0003] For a long time, especially the equipment put into use from the 1990s to the beginning of this century, due to the lack of advanced control technology and equip...

But central air-conditioning is the equipment with the largest energy consumption in buildings. While it brings us a comfortable air-conditioning environment, it also brings huge energy consumption.

[0003] For a long time, especially the equipment put into use from the 1990s to the beginning of this century, due to the lack of advanced control technology and equipment, most central air-conditioning systems still use traditional manual management and simple switch control equipment, which cannot achieve air-conditioning and cooling effects. Timely and accurate follow-up adjustments follow the changes in the end load, which will cause a lot of energy waste during partial load operation, resulting in low building energy efficiency
