Abstract:
염료감응 태양전지(Dye-sensitized solar cell, DSSC)를 이용한 가스충진형(Gas filled) 태양광열 복합 시스템(DSSC/Thermal, DSCT)은 상부로부터 유리커버, 가스층(Ar Kr, Xe 등), 염료감응 태양전지, 접착층, 태양열 집열판, 흡수관, 단열층, 프레임 순으로 구성되며, 작동유체는 저장탱크(Storage tank)로부터 펌프에 의해 흡수관 내부로 유입, 집열된 후 다시 저장탱크로 돌아오는 구조를 가지고 있다. 이는 기존 태양에너지 단일 이용 시스템(PV 모듈, 태양열 집열기) 대비 단위면적당 태양에너지 이용률이 향상되며, 태양광열 복합(Photovoltaic/Thermal, PVT) 시스템의 내부 온도 상승에 따른 전기효율 감소라는 문제점을 해결할 수 있는 복합 응용 기술로 판단된다. 더불어, 유리커버와 DSSC 사이에 충진되는 가스를 온도에 따라 유동적 특성을 갖는 공기 대신 비활성기체인 Ar, Kr, Xe을 포함하는 가스를 적용하여 외부로의 열손실을 최소화할 수 있을 것으로 판단된다.
Abstract:
PURPOSE: A gas-filled photovoltaic thermal composite system using a dye-sensitized solar cell is provided to minimize a heat loss from the outside by applying a gas with Ar, Kr, and Xe between a glass cover and the dye-sensitized solar cell. CONSTITUTION: A glass cover (304) blocks a convection heat loss by a dye-sensitized solar cell (301) and external air. A gas layer (307) is formed between the glass cover and the dye-sensitized solar cell. One or more among a group of Ar, Kr, and Xe are selected to be filled in the gas layer. The dye-sensitized solar cell is bonded to a collection plate (305) by an adhesive. An installation space between the glass cover and the collection plate is 10 to 12 mm.
Abstract:
The present invention provides a dehumidification apparatus using an aqueous solution of lithium bromide comprising a dehumidification pad drenched in the aqueous solution of lithium bromide; a spray nozzle installed on the top of the dehumidification pad to supply the aqueous solution (concentrated solution) of lithium bromide; and a support tank installed below the dehumidification pad to collect the aqueous solution (dilute solution) of lithium bromide which has absorbed moisture. The dehumidification apparatus can further comprise a pump for transferring the dilute solution contained in the support tank to a regeneration system; a storage tank for collecting the dilute solution; a heating part for regenerating the concentrated solution by evaporating moisture from the dilute solution; and a pump for supplying the concentrated solution to the spray nozzle of the dehumidification apparatus again.
