“…8 Facing with the pressure of environmental degradation and energy and environmental policy, glazing windows have become a vital argument for building conservation. 9 Many methods including film and coating, [10][11][12] shutter, 13,14 and glass structures [15][16][17] have been developed to improve the thermal resistance of window units. Some practical examples of these techniques have been evaluated for different climatic conditions of Mexico.…”

“…Some practical examples of these techniques have been evaluated for different climatic conditions of Mexico. [15][16][17] Solar energy, as a kind of pollution-free and renewable clean energy, is one of the important energy sources for buildings. 18,19 Therefore, it is a feasible way to reduce energy consumption and improve indoor thermal comfort if the solar energy can be exploited by the window unit.…”

Summary A two‐dimensional heat transfer model was proposed to numerically investigate the effect of enriching phase change material (PCM) with different kinds of nanoparticles on thermal performance of glazing windows in different seasons of the year. The results were presented in terms of liquid fraction of PCM, inner surface temperature and temperature difference between interior and exterior surfaces of glass window, and their occurrence times. The results showed that adding nanoparticles into PCM can promote the melting and solidification processes, extend the total time of PCM being in the liquid state, and raise the internal surface temperature of glass. However, in summer season, the internal surface temperature decreases and the total melting time respectively reduces by 7 and 1.5 minutes by introducing TiO2 and ZnO nanoparticles into PCM. Furthermore, the introduced nanoparticles do not have the same effect on the thermal performance of the window unit. While the inner surface temperature decreases by 0.82 K in summer by addition of TiO2 to PCM, it increases by 0.84 K in transition season and 0.89 K in winter season by utilizing ZnO nanoparticles. Although the nano‐PCM remains in the solid state in winter, the existence of nanoparticles can still increase the inner surface temperature.

“…Xamán et al. 27 extended their aforementioned steady-state simulations to a pseudo-transient simulation of the closed DGU to appraise the thermal performance of the glazing for a warm day in Mexico. Numerical results showed that during the whole diurnal period, the solar control coating in a double pane window reduces the amount of energy to the indoors by almost 55%.…”

“…Also, a few of those studies are related to transient or pseudo-transient computational fluid dynamics (CFD) simulations to assess the annual thermal behaviour of a DGU in a variety of climatic conditions. 22,27 This work is focused on evaluating the thermal performance of an energy-efficient open double-glazing system regarding to a conventional double clear glazing configuration proposed by building energy standards in Mexico. Therefore, the aim of this study is to develop a pseudo-transient numerical model to predict the thermal performance of an open double-glazing unit (ODGU) in four different climatic conditions in Mexico (Mexicali; extreme warm dry, Monterrey; semi-arid, Puebla; temperate and Merida; tropical wet and dry).…”

The annual thermal evaluation of an open double-glazing unit (ODGU) is presented. The ODGU was modelled using two double-glazing configurations: DCC (clear glass + air + clear glass) and DCA (clear glass + air + absorbent glass). Numerical simulations were performed for the warmest design-day on each month of 2016 in four different climatic conditions in Mexico. The pseudo-transient simulations were carried out using an in-house code based on the finite volume method. To obtain the results, 5856 computational runs were necessary. From the results, the DCA configuration was observed to show the best thermal performance to reduce heat flux that passes through the inside space in the extreme warm dry climate with average reductions of 97 W/m2, followed by the semi-arid climate with 84 W/m2 and the tropical wet and dry climate with 82 W/m2 on a yearly basis. On an annual average, the DCA configuration in the extreme warm dry climate reached almost twice the mass flow rates than those observed in the temperate climate. From the numerical simulations, we have concluded that the use of the low-cost DCA configuration in warm climates was the best solar passive strategy for saving energy in buildings throughout the year.

“…Using the glazing material available in the Mexican market, researchers have also investigated the thermal performance of a room with a double-glazed window [10,11]. A thermal evaluation of a room with a double-glazed window both with/without a solar-control film made in Mexico was also presented [12][13][14]. Based on the results, we know that a room with a double-pane window with a solar-control coating is associated with a smaller heat flux than one with a window without a solar-control coating.…”

In this paper, we present a two-dimensional numerical analysis of the conjugate natural convection and radiation heat transfer in a double-space enclosure with two semitransparent walls. Two kinds of boundary conditions are considered, the first being the isothermal process of the opaque wall, and the other the incidence of a constant radiation flux in the left semitransparent wall. The renormalization group k-ε model is adopted to simulate the turbulent flow in the enclosure. To compute the radiation heat transfer in a semitransparent medium, the discrete ordinates model is used. We compare the behaviors of enclosures with single and double semitransparent walls and determine the difference in the results obtained for semitransparent and opaque partitions. The results indicate that a semitransparent partition facilitates a reduction in the heat loss or obtains a higher temperature distribution. The transmittance of a semitransparent wall has a great effect on the thermal and flow characteristics in an enclosure. The change of wall temperature is found to be significant when the thermal conductivity values range from 0.05 to 0.5 W/(m•K), and to be small when ranging from 0.5 to 10 W/(m•K). These conclusions are helpful for green design and energy saving in solar buildings.
