Photo-thermal dynamic balance regulation and control method for building skin variable component

Abstract

The invention discloses a photo-thermal dynamic balance regulation and control method for a building skin variable component, and belongs to the field of buildings. A photo-thermal dynamic balance regulation and control method for building skin variable components comprises the steps: determining description indexes and comfort threshold values of a photo-thermal environment; conducting parametric modeling on the building skin variable components; importing outdoor simulation meteorological parameters; conducting annual hourly effect simulation calculation analysis on the opening states of all the variable components; calculating the distance between the indoor photo-thermal environment and a preset comfort range threshold value under the opening state of each variable component at the moment i; processing the distance data between the photo-thermal environment and the preset comfort range; comparing to obtain the opening state of the variable component with the optimal comprehensive effect at the moment i; summarizing to obtain a year-round hour-by-hour comprehensive optimal variable component opening state set and automatically controlling opening of the variable component by using the set. By means of the method, the light environment and the heat environment of the building outer skin variable component are jointly optimized, and balance regulation and control between solar heat radiation and natural lighting are achieved.

Description

technical field [0001] The invention belongs to the field of construction, and in particular relates to a method for regulating and controlling the dynamic balance of light and heat of a variable member of the building skin. Background technique [0002] Solar thermal radiation and natural daylighting are a group of closely related variables. However, for the southern region, this group of variables presents contradictory effects of one body and two sides. How to deal with the contradiction between natural lighting and solar heat radiation has become an important issue for the realization of comfort, energy saving and high efficiency of green buildings in the southern region (referred to as the light and heat problem); [0003] The current way to deal with the problem of light and heat has the following defects: 1) The design of building natural lighting and building shading design are carried out separately, ignoring the duality of solar thermal radiation and natural lighti...

Problems solved by technology

[0003] The current way to deal with the problem of light and heat has the following defects: 1) The design of building natural lighting and building shading design are carried out separately, ignoring the duality of solar thermal radiation and natural lighting, which is easy to lose sight of the other, which is not conducive to the overall comprehensive judgment; 2) Fixed 3) At present, the variable components of the building skin are mostly sunshade components, and the adjustment method is to block the excessive solar radiation entering the room as the control target, which is easy to weaken the natural lighting. Cause indoor illumination is too low;
