Determining method of optimal intermittent cooling adjusting and controlling scheme for embedded pipe type enclosing structure

Abstract

The invention discloses a determining method of an optimal intermittent cooling adjusting and controlling scheme for an embedded pipe type enclosing structure. The method comprises the following stepsthat firstly, physical models of a dwelling building and the embedded pipe type enclosing structure are built; secondly, the structures and thermal parameters of the dwelling building model and the embedded pipe type enclosing structure are set, and internal and external disturbances of the dwelling building model are set; thirdly, cooling duration schemes and cooling duration evaluation indexesof an embedded cold water supply pipe are determined, and weights of the cooling duration evaluation indexes are obtained; fourthly, the optimal cooling duration scheme in the dwelling building modelis obtained; and fifthly, the optimal cooling time distribution scheme in the dwelling building model is obtained. The steps of the method are simple, subjective factors and objective factors are effectively combined to optimize the cooling duration schemes and the cooling time distribution scheme, the determined optimal intermittent scheme can better meet the actual cooling requirements without losing scientific and objective properties, and the optimal design problem of balancing comfort, energy saving and economical efficiency is effectively solved.

Description

technical field [0001] The invention belongs to the field of embedded tubular enclosure structures, and in particular relates to a method for determining an optimal intermittent control scheme for cooling of an embedded tubular enclosure structure. Background technique [0002] The embedded pipe enclosure structure is to embed fluid pipes in the building body such as floors, floors or walls in the early stage of building construction, and transfer heat through the flow of water in the cooling pipes to achieve the cooling effect. The cooling component of the embedded tube enclosure structure can be regarded as a cold source and a large cold storage body at the same time. Its heat storage and release characteristics make intermittent regulation superior, and its cold delay characteristics can make the enclosure structure of intermittent operation The cooling system exerts its energy-saving characteristics on the basis of maintaining indoor temperature stability. Although many...

Problems solved by technology

Although many projects in China have realized the advantages of intermittent cooling and tried to use it in practice, most of the existing projects set the intermittent scheme subjectively, and it is easy to fall into a situation where a single performance index is optimal and other performance indexes are poor. Disadvantages, unable to achieve multi-objective comprehensive optimization of comfort, energy saving and economy
