진공관형 집열기를 이용한 태양열 흡수식 냉방 시스템 실증연구

This paper presents demonstration study results derived through field testing of a part load solar energized cooling system for the library of a cultural center building located in Gwangju, Korea. The area of demanded cooling for building was about 350㎡. Solar hot water was delivered by means of a 200㎡ array of evacuated tubular solar collector (ETSC) to drive a single-effect (LiBr/H2O) absorption chiller of 35kW nominal cooling capacity. During the demonstration tests, operating conditions of the solar cooling system are established through modifications of the various control parameters. Operation data for 10stable hours at a clear sky day during the summer season are achieved and analyzed for the verification of the availability, stability, and reliability of the present system.
