System and method for optimizing operation of cooling and heating devices in area

Abstract

The invention provides a system and method for optimizing the operation of cooling and heating devices in an area. The method comprises the following steps that: S1, an upper computer queries historical load records, conforming to a current environmental temperature and humidity trend, in a historical database according to the according to a current environment temperature and humidity trend; a heating and ventilation load calculation model is invoked to calculate a typical design standard load; and weighted summation is carried out based on the historical load and the standard load, and a predicted load of a next cycle is calculated; S2, devices that meet the load need, have the matched host rated cooling capacities, and having the longest / shortest operation time are screened and serial numbers of the devices are obtained; S3, operation target parameters of the corresponding systems of the devices are calculated; and a field controller acquires a serial number of a device needing to be added or removed as well as the operation target parameters through a data channel and controls device increasing / decreasing and device operation states in the area; and S4, the S1 is performed again and closed loop control is formed. Therefore, the equipment operation efficiency is improved; the cost is lowered; and the energy consumption is reduced.

Description

technical field [0001] The invention belongs to the field of the air-conditioning industry, and in particular relates to a system and method for optimizing the operation of district cooling and heating equipment. Background technique [0002] From the perspective of protecting the environment and improving energy utilization efficiency, for cities with dense population and tight space, it is the development direction of urban central air-conditioning to adopt regional centralized supply (DHC) for the cold and heat required by building air-conditioning. [0003] Due to the many types, quantities and wide distribution of equipment in the district cooling and heating system, it is often operated with the maximum number of equipment configurations in actual operation. It is difficult for individuals to dynamically screen out various places and various high-efficiency equipment in real time according to the external cooling / heating load and adjust them. The running quantity and r...
