Modeling, Simulation and Testing of Atomization Temperature Change Point of Thermochromic Glass for Building Energy Saving
Abstract
Thermochromic glass possesses great potential for reducing the energy demand and providing indoor comfort in buildings. Suitable atomization temperature change points have a great influence on the application of thermochromic glass. Based on energy consumption simulations and theoretical calculations by introducing solar radiation in a transparent envelope, this paper investigates the atomization temperature change point of thermochromic glass in hot summer and cold winter zones in Chongqing, showing that the suitable temperature change point of the thermochromic glass is 39°C with air conditioning and 42.9°C without air conditioning. Furthermore, the results of simulations and theoretical calculations are applied to a test model, revealing that thermochromic glass with the temperature change point of 42.9°C compared with Low-E glass can reduce the temperature of a sunlight room by up to 5°C in the summer and displays a certain thermal insulation effect in winter.
