Abstract

In recent years, radiation refrigeration materials have developed rapidly, and a lot of research has been carried out from simulation and experimental testing. In this paper, the radiation refrigeration coating is applied to a small residential container building in Chengdu area. The experimental results show that the radiation refrigeration coating can reduce the indoor temperature and improve the indoor thermal environment. Combined with the numerical simulation analysis, it is found that the radiation refrigeration coating is suitable for the roof of the building, which can reduce the energy consumption of 2.47 kWh/ m2 per unit area per year.
