“…It can be seen from Figures 5-7 that the changing trend of ventilation rate is similar to that of the air temperature 4 International Journal of Photoenergy difference between inlet and outlet. Higher phase change temperature leads to poor chargeability of the chimney and has the shorter ventilation time.…”

Thermal storage capacity and airflow rate of a solar chimney combined with different PCMs are numerically studied during nighttime. PCMs with phase change temperatures of 38°C, 44°C, 50°C, and 63°C are selected in this numerical study. Results show that the maximum average ventilation rate of 610 kg/m 2 and maximum thermal storage of 4750 kJ/m 2 are achieved at the phase change temperature of 38°C. However, for phase change temperature of 63°C, night ventilation does not occur under the identical conditions. The findings reveal that a lower phase change temperature can increase the chargeability (and therefore the dischargeability) of a solar chimney, since a higher phase change temperature demands higher solar radiation intensity and longer charging time for a solar chimney. For PCM with a phase change temperature of 44°C, most of the heat stored in PCM is lost to ambient through glass cover by radiation and only a small portion is used for heating the air within air channel.

“…They carried out a theoretical analyses to study the cooling and ventilation of a house employing a solar chimney together with earth to air heat exchanger. Susanti et al [24] developed a mathematical model to simulate air velocity and temperature of a roof cavity, which was utilized to improve the thermal environment and reduce the cooling load of a factory building. DeBlois et al [25] used zonal building modeling to study the ventilation performance and energy savings of a house with roof solar chimney in four US climates.…”

Abstract. As a special form of architecture, the internal thermal environment of tents is very poor because of the simple envelop. This paper summarized the research status of thermal environment of tents based on the foreign and domestic research results in this field and pointed out the research direction. This work can provide the reference and instruction for further study on improving thermal environment of tents.
