An Experimental Study on the Thermal Performance of the Night Insulation Devices in Passive Solar System |
| Abstract |
The research has been conducted to develop guidelines in designing night insulation devices for passive solar system in order to maximize thermal efficiency. After an extensive literature search being conducted to investigate the state-of-art of night insulation development, three scale models were constructed representing Dircet Gain, Trombe Wall and Attached Sunspace. Each Model contained two identical thermal rooms;one installed with a night insulation devece for expreiment, and the other without night insulation for control. The thermal performance of the models was monitored with various various night insulation devices during the heating seasons between 1988 and 1990.At the same time, a simple dynamic thermal analysis program was developed to model thermal performance of passive solar system and especially that of night insulation devices. The result of the computer simulation was found to be consistent with the result of physical model tests, and therefore, diversified analyses were made possible. |
