Summary

THE DOUBLE SKIN, WHICH IS A GLASS-COVERED SPACE SIMILAR TO A GREENHOUSE, REFLECTS THE SUN AND RELEASES HEATED AIR BY NATURAL VENTILATION IN SUMMER, AND WORKS AS A SOLAR COLLECTOR IN WINTER. THIS PAPER DESCRIBES THE EVALUATION OF THE PERFORMANCE OF THE DOUBLE SKIN IN THE SUMMER MODE WHERE THE AIR TEMPERATURE IN THE SKIN IS ONLY 3-4 K HIGHER THAN THE OUTSIDE TEMPERATURE AND IN THE WINTER MODE WHERE THE FRESH AIR TAKEN INTO THE AIR HANDLING UNITS IS HEATED. EFFICIENCY OF SOLAR COLLECTION TO THE INSOLATION IS ABOUT 16% AND THE OUTLET AIR TEMPERATURE IS BETWEEN 300 AND 305 K (27 AND 32 DEG C). THE DOUBLE SKIN COLLECTS SOLAR ENERGY OF 500 KILOCAL/M2.DAY ON A FINE DAY IN THE WINTER. ENERGY SAVING PERFORMANCE IS 22% IN THE SUMMER MODE AND 24% IN THE WINTER MODE.
