Abstract

Passive solar house can improve indoor thermal comfort, but produce the problems of overheating in summer and inconvenient for operation. To solve the existing problems, solar wall with color changed was proposed and a full-scale experimental house with color changed was built in Dalian. Thermal response characteristics of this passive solar house were studied by two years experiments. After analyzing experimental data, the correlation function of indoor thermal environment parameters (indoor air temperature and south wall inner surface temperature) and outdoor air temperature under different operation conditions were presented. Analysis of the humidity level in the indoor environment of the passive solar house indicated that passive heating could restrain condensation on the walls. However, condensation occurred on the thermal bridges at the inlets and outlets of solar walls after the fans were turned off. Therefore, thermal bridges should be avoided during design phase. Taking λρc values of building envelope as the characterization parameter, results of heat flux direction and values of building envelope were obtained, which showed that thermal storage effect of floor was blindingly obvious. Building envelope stored heat during the day and released heat at night, and the average heat flux density at night was between 1 W/m2 and 10 W/m2.
