Field Measurement and Evaluation of the Passive and Active Solar Heating Systems for Residential Building Based on the Qinghai-Tibetan Plateau Case

Abstract

Passive and active solar heating systems have drawn much attention and are widely used in residence buildings in the Qinghai-Tibetan plateau due to its high radiation intensity. In fact, there is still lack of quantitative evaluation of the passive and active heating effect, especially for residential building in the Qinghai-Tibetan plateau areas. In this study, three kinds of heating strategies, including reference condition, passive solar heating condition and active solar heating condition, were tested in one demonstration residential building. The hourly air temperatures of each room under different conditions were obtained and analyzed. The results show the indoor air temperature in the living room and bedrooms (core zones) was much higher than that of other rooms under both passive and active solar heating conditions. In addition, the heating effect with different strategies for core zones of the building was evaluated by the ratio of indoor and outdoor degree hour, which indicates that solar heating could effectively reduce the traditional energy consumption and improve the indoor thermal environment. The passive solar heating could contribute 49.8% degree hours for heating under an evaluation criterion of 14 • C and the active solar heating could contribute 75% degree hours for heating under evaluation criterion of 18 • C, which indicated that solar heating could effectively reduce the traditional energy consumption and improve the indoor thermal environment in this area. These findings could provide reference for the design and application of solar heating in similar climate areas.

Analysis and use of building heating and thermal energy management system

“…In terms of residential equipment and control devices, it has also achieved the most advanced level at present. At present, the mode of urban heat supply in China mainly includes the mode of common operation of thermal power and boiler, and the mode of air conditioning, electric gas heating and heating [14].…”

Analyzing the Interactions among Barriers to the Use of Solar Energy for Heating in Residential Buildings in Van, Türkiye

“…Since the world energy crisis in the 1970s, the importance of using renewable energy sources has been recognized, and publications on the use of solar energy have been produced worldwide and in Türkiye [5][6][7][8][9][10][11][12][13][14][15].…”

“…The most important reason for conducting the study locally in the City of Van is that the barriers to energy-efficient construction in the context of sustainability and the use of solar energy in the heating of houses via active and passive methods have location-specific physical, social, and economic reasons [19,20,29,32,33]. Since the world energy crisis in the 1970s, the importance of using renewable energy sources has been recognized, and publications on the use of solar energy have been produced worldwide and in Türkiye [5][6][7][8][9][10][11][12][13][14][15].…”

Numerical Simulation of Thermal Storage Performance of Different Concrete Floors

“…Accordingly, [3,4] the thermal physical properties of the internal materials of a floor have an important influence on the heat storage ability of the floor. The change to a modern life style has increased [5] the heating demands of households at night, with intermittent heating becoming an inevitable trend [6,7]. According to the periodicity of sunshine, solar energy is used in the winter for heating purposes and meets the heating demand of households while saving energy.…”
