The goal of the present paper is to show the optimum design and operation conditions on 6 kW solar water heating system by using computer simulation with verified modelling. As the object functions, we took not only the amount of acquired and auxiliary heat but LCC, which has a relative importance and decisive role in economy. As expected, the maximum heat is acquired at the slope of collector with the equal degree to the latitude, facing the south. The capacity increase of the circulation pump and the storage tank lead to the increase of acquired heat and the decrease of auxiliary heat, but do not necessarily give economical advantages owing to additional electrical power consumption. In the present system, the minimum LCC can be obtained at the storage tank volume of 450 L and the mass flow rate of 0.344 kg/s.

This paper presents demonstration study results derived through field testing of a solar assisted cooling and heating system for the library of a cultural center building located in Gwangju, Korea. The area of demanded cooling and heating for building was about 350m2. Solar hot water was delivered by means of a 200m2 array of evacuated tubular solar collector (ETSC) to drive a single-effect (LiBr/H2O) absorption chiller of 10RT nominal cooling capacity. From March in 2008 to February in 2009, demonstration test were performed for solar cooling and heating system. After experiments and analysis, this study found that solar thermal system was 84% for the solar hot water supply and 12% for space heating and 4% for space cooling.

CES(Community Energy System)란 구역형의 소규모 지역냉난방시스템으로 세계에서 일본이 가장 발달된바, 일본의 도입 실태분석이 향후 국내 CES 도입에 중요한 자료가 될 것으로 판단되므로 일본에서의 소규모 지역냉난방시스템 도입사례에 대한 조사분석한 내용을 소개하고자 한다. 일본에서의 지역열공급사업의 개념은 1개소 또는 수개소의 열공급플랜트로부터 복수의 건물에 지역배관을 통하여 냉수ㆍ증기ㆍ온수 등을 보내어 냉난방ㆍ급탕을 행하는 것이다.(중략)

This paper reviews the current status of R&D work on selective absorber materials. For the efficient utilization of solar energy, various types of selective absorber materials are being used for solar hot water heaters. Many selective absorbers which have been proposed and designed up to data are classified according to the absorption mechanisms. Temperature-time cycle method is often recommended for the measurement of solar absorptance. In addition, conversion efficiency of the solar collector with selective surface is compared with one with black paint surface.

1973년과 1978년의 1,2차 Oil Shock로 인하여 정부는 대체에너지 개발을 입법화하여 태양열의 이용을 촉진시켜왔다. 그 후 약 20년간 태양열 이용에 대한 효과적인 집열과 축열기술의 개발에 연구가 추진되었으며, 집열판(Flat-plate collector)의 개발과 열교환기, 축열장치의 설계 등 효율향상을 통하여 건축의 난방, 온수급탕 등이 주종을 이루었다. (중략)
