Problems solved by technology

Existing EC glass window control usually adopts a single-parameter feedback control method or a simple schedule control method, which cannot solve the optimal control problem of multiple control targets in the solar and thermal environment, which is not conducive to building energy saving
These problems affect the control performance of EC glass windows and restrict their efficient application in buildings

Abstract

The invention, which relates to the field of smart windows, provides an energy-saving type intelligent external window optimization control method. An EC casement window regulation strategy is determined according to different regions, different building types, and different orientations; the solar radiant heat can be utilized effectively, the natural lighting is increased, and glaring is avoided;and the optimized control problem of the multiple control targets in a photo-thermal environment is solved and the building energy consumption is reduced. According to the invention, on the basis ofarchitectural design parameters of the electrochromic casement window, control logics of the electrochromic casement window are set in an EnergyManagement System module of the EnergyPlus; with Genoptsoftware, an outdoor horizontal illumination control threshold of a control parameter of the electrochromic casement window state in the established EnergyPlus simulation model is optimized, so that the sum of the illumination energy consumption and the air conditioning energy consumption of the building simulation is minimized. Therefore, the building energy consumption is reduced effectively; and incorrect usage of the electrochromic casement window due to different regions, different orientations, different building types and different seasons is reduced effectively.

Description

technical field [0001] The invention relates to the field of smart windows, in particular to an energy-saving-based optimization and control method for smart outer windows. Background technique [0002] Glass windows are an essential part of the building envelope. Visible light and radiant heat entering the room through the glass have an important impact on the building's photothermal environment and energy consumption. The optical properties of traditional glass are "static" during use, and the amount of solar heat transmission can only be "passively accepted", and cannot be "actively adjusted" according to changes in outdoor weather conditions and building requirements. This problem is the bottleneck restricting the energy saving of glass windows, and it is also the main source of high building energy consumption and poor environmental comfort when large-area glass windows are used in modern buildings. [0003] The emergence of electrochromic (EC) glass energy-saving tech...
