초록
It will be desirable things that if cooling and heating can be obtained simultaneously with one device without using power. This study was tried to investigate the feasibility for combined device of unpowered cooling and heating. The absorption device of solar heat was contrived to perform natural cooling in case of summer and natural heating in case of winter, respectively. For these purposes, experimental structure (house) and absorption device of solar heat, which was performed surface treatment, were manufactured and tested over summer and winter. As the results, in summer, inlet flow rates of air in case of installing absorption device of solar heat were increased about 12 to 20 times compared with those of no installing. In winter, the case of installing absorption device of solar heat showed maximun 6℃ high temperature in day time and 1～3℃ high temperature in night time compared with those of no installing. Furthermore, inside temperature of experimental structure showed maximun 14℃ higher than outside temperature in day time.
