RESEARCH ON THE ENERGY-SAVING EFFECT OF COMPOSITE FILM MATERIALS ON SMART WINDOWS BASED ON OPTICAL PROPERTIES

ABSTRACT
As the industrial and economic level continues to develop, the urban heat island effect is then serious. In order to control the indoor temperature in life and production and improve the indoor environment in summer, the study was conducted on composite film materials for smart windows for buildings. An optical analysis of the cooling requirement was conducted first, and then the material was modified based on this, and a composite film material based on polydimethylsiloxane (PDMS) and Ag coating was made. The test results show that the composite film can change the spectral absorption of the object and reduce the temperature of the object by 16.7 °C under the same light scenario. Tests on commonly used low-e glass show that the composite film material can reduce room temperature with increased sunlight transmission. Finally, a cooling test on PV panels used for building energy efficiency effectively reduced the operating temperature of the units, although it could not directly affect the power generation efficiency. This shows that the PDMS composite film based on optical properties can reduce the indoor temperature, thus reducing the power of electric cooling. The energy saving effect has positive significance for building windows.
