Heat activation building system equivalent outdoor temperature prediction control method

Abstract

The invention discloses a heat activation building system equivalent outdoor temperature prediction control method. The method comprises the following steps of calculating heat dynamic characteristics, energy consumption and comfort of a building; measuring the indoor air temperature and average radiation temperature; measuring heat transfer quantity of the enclosure structure, indoor personnel heat dissipation, lamp light heat dissipation, indoor equipment heat dissipation and air infiltration heat quantity; predicting the equivalent outdoor temperature according to the predicted outdoor temperature value and the solar radiation value; comprehensively predicting the water supply temperature of the heat activation building system; and adjusting the predicted water supply temperature according to the heat transfer delay time of the heat activation building system. According to the method, the equivalent outdoor temperature is predicted by comprehensively considering the influence on theheat dynamic characteristics of the enclosure structure and integrating calculation in multiple aspects, the delay effect of heat transfer of the heat activation building system is considered, the delay of heat transfer of the heat activation building system is taken as a factor of equivalent outdoor temperature prediction control, and the accuracy of equivalent outdoor temperature prediction control is improved.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a method for predicting and controlling the equivalent outdoor temperature of a heat-activated building system. Background technique [0002] Due to its own structural characteristics, the heat-activated building system and the physical structure of the pipe embedded in the wall make the heat transfer to the wall first, and then the wall exchanges heat with the indoor air. The delay in heating time cannot maintain indoor comfort well; [0003] In the existing heating / cooling system, when considering the influence of solar radiation on the indoor environment, it is considered from the perspective of converting solar radiation into indoor load. As people's requirements for comfort are getting higher and higher, the indoor temperature caused by solar radiation The change must be considered in the overall operation planning of the building. Therefore, the present invention pr...
