Thermal evaluation of a Room coupled with a Double Glazing Window with/without a solar control film for Mexico

Abstract

The thermal evaluation of a Room (R) coupled with a Double Glazing Window (DGW) with/without solar control film (SCF) under warm and cold climate conditions of an extreme weather of Mexico is presented. The right vertical wall of the room is partially adiabatic and contains the DGW. The DGW consists of two vertical semitransparent walls: glazing-1 facing the room, and glazing-2 facing the external environment. The SCF is attached to glazing-1 for cold climate condition, or attached to glazing-2 for warm climate condition. During one day, hourly simulations of the R-DGW were done using an in-house code based on the finite volume method. Three cases were defined to analyze the R-DGW system: Case C1 corresponds to the R-DGW without SCF; Case C2 and C3 correspond to the R-DGW with SCF for warm and cold climate conditions, respectively. For warm climate condition the use of a SCF is highly recommended, since the Case C2 was able to reduce ≈62% of the energy gains with respect to Case C1. When the solar control coating in double glass window is used for cold climate condition (case C3), the average temperature inside of the room is similar to the case C1.
