| Popis: | A compact solar air heating unit for space heating is developed and tested using four types of Jordanian rocks in their natural forms as the heat storage medium. The collector efficiency equation, hence the system design parameters, and the heat capacities of the rocks in the storage space environment are determined. The results are used in an application: heating a 220 m 2 floor area house in the Amman area. It is found that, by using a collector area of 50 m 2 , the annual heating load supplied by solar energy amounts to about 52% of the total load; if the collector area increases to 100 m 2 , the percentage of the load supplied by the solar source increases to 81%. The storage volume required for 50 m 2 of collector area, if tarsand is used as the storage medium, is about 8.9 m 3 , if zeolite is used for storage instead, the storage volume drops to about 3.5 m 3 . The results reported in this paper adequately support the tested solar heating unit as an alternative to the classical packed bed systems. |
