GEOGRAPHICAL VARIATION IN PERFORMANCE OF AN UNGLAZED SOLAR SYSTEM MEETING WATER HEATING AND SPACE CONDITIONING LOADS

摘要

This paper presents simulated performance across the continental U.S. of an unglazed collector system supplying domestic hot water, space heating, and space cooling loads. The collector model is based upon an ISO test for unglazed collectors that explicitly includes affects of wind and sky infrared. To provide realistic loads as location varies, building envelope characteristics vary according to code specifications. Maps of savings for heating and cooling are presented. The U.S. southwest region shows largest savings for both heating and cooling. Average heating efficiency varies from 13% to 28% for collector sizes from 24 m{sup}2 to 6 m{sup}2, respectively. Monetary savings and system cost goals are given for an all-electric and a (natural gas + electric) scenario.
