A Study on the Application Method of Photovoltaic in Building
Lee, E.J. ; Kim, H.S. ;
Journal of the Korean Solar Energy Society, volume 22, issue 2, 2002, Pages 1~10
This study is a study on the building integrated method of Photovoltaic. It was analyzed into a basic installation condition and an integrated form in this study. And it was confirmed through the 3D simulation & drawing work of an integrated situation to the real domestic building. The Photovoltaic installation of the country to an optimal efficiency for the year must be installed to the due south with an angle of thirty degrees. And also a module spacing must be more than doubled from the bottom to the top of module to prevent from efficiency falling by a shadow of photovoltaic module in a roof setting of flat roof. If Photovoltaic module is an adequate material that is a basic requirement as a building's finishing material, it's not only an efficiency of alternation with an existing finishing material but also a building's design element.
Experiment on the Charge and Discharge of Thermal Energy for Under-Water Harvest-Type Ice Storage System
Kim, J.D. ;
Journal of the Korean Solar Energy Society, volume 22, issue 2, 2002, Pages 11~17
This paper is concerned with the development of a new method for making, separating ice and storage floated ice by installing an evaporation plate at under-water within a storage tank. In a conventional harvest-type ice storage system, a tank saves ice by separating an ice from an installed evaporation plate, which is located above an ice storage tank as an ice storage system. Developed new harvest-type method shows good heat transfer efficiency than a convectional method. It is because the evaporation panel is directly contacted with water in a storage tank. Also, at a conventional system a circulating pump, a circulating water distributor and a piping are installed, however these components are not necessary in a new method. In this study ice storage systems are experimentally investigated to study the charge and discharge of thermal energy. The results show the applicable possibility and performance enhancement of a new type.

Journal of the Korean Solar Energy Society, volume 22, issue 2, 2002, Pages 19~26
This study aims at numerically analyzing on heat transfer the characteristics and pressure drop of plate heat exchanger(PHE) using the Phoenics 3.1 VR Editor for the standard k-
model. Computations have been carried out for a range of chevron angle from
, inlet velocity from 0.03m/s to 0.63m/s and the height of corrugation from 0.0045m to 0.0060m. The results show that both of heat transfer performance and pressure drop increase as chevron angle increases. This is because higher troughs produce higher turbulence and a higher heat transfer coefficient in the liquids flowing between the plates. As inlet velocity from 0.03m/s to 0.63m/s increases, heat transfer performance and pressure drop increase parabolically. As the height of corrugation increases, both of heat transfer performance and pressure drop decrease with the decrease of velocity. And the pressure drop decreases and the friction factor increases as the height of corrugation increases.

The Characteristics of heat transport in the heat pipe with a double vapor path and different kinds of the working fluid were investigated experimentally. The Experiment was carried out with acetone/ethanol. ethanol/ethanol. and in the aluminium container of the double vapor path. Performance measurements can be operated at the high level by 24000 w/m2 heat flux in the 1000mm evaporator. They are each estimated at the high temperature and experimentally reviewed the characteric of the heat rejection. The results shew that they are stably operated under each condition and the fluid was complemented each other at the fluid's experiment and brought about the extention of operating temperature. In this study, The reliable basic data obtained by the teste in the heat pipe with a double vapor path can be used for thermal design, manufacture, and production etc.

Journal of the Korean Solar Energy Society, volume 22, issue 2, 2002, Pages 33~38
In order to find out whether solar air conditioning system could be applied to building or not, the performance and evaluation on thermal environment of the system suggested was done during summer. A solar model house was constructed to find out the performance and thermal environment evaluation when it actually operated outside. As a result, regeneration rate increased rapidly when LiCl solution temperature was over
and the regeneration rate was
during 9 hours operation. Furthermore the dehumidification rate was 12kg at maximum during 10 hours operating of a dehumidifier and indoor temperature and relative humidity was
and 39.1% in average respectively. On evaluation of thermal environment during summer, PMV value was slightly high, but thermal sensation vote was 71% within the comfort zone.

Journal of the Korean Solar Energy Society, volume 22, issue 2, 2002, Pages 39~47
The thermosyphon SDHWS and the loop type thermosyphon systems are widely used for domestic hot water system. The loop type thermosyphon is a circulation device for transferring the heat produced at the evaporator to the condenser area in the loop. In this study, the operating characteristics of various working fluids being used have been identified. The working fluids employed in the study were ethanol. water, and a binary mixture of ethanol and water. The volume of working fluid used in this study were 30%, 40%, 50%, 60% and 70% of evaporator volume. It is observed that, in the thermosyphon with low volume of working fluid, such as 30% or 40%, the fluid was dried out. The flow pattern and mechanism of the heat transfer were identified through this study. Flow patterns of the binary mixture working fluid were also investigated, and the patterns were recorded in the camera. The system parameters were calculated using the thermal performance data. Modelling of the system was carried out using PSTAR method and TRNSYS program.

Journal of the Korean Solar Energy Society, volume 22, issue 2, 2002, Pages 49~59
Recently, due to high rise building by rapid urbanization, the spaces incapable of being penetrated by sunlight into interior is increasing. So, sunlighting systems are important means to be able to get sunlight into indoors and to make sure of sunshine awareness. This study aims to evaluate lighting performance of sunlighting mirror systems. As results. these are very useful for the increase of an average illuminance of indoors and the penetration of sunlight. Especially, the second reflecting mirrors can be applied to spaces lack of sunlight. And these sunlighting systems developed in the present study is validated physical and psychological performance to both building and people.

Daylighting is a powerful vehicle of architectural expression and provides buildings a living quality due to constantly changing properties in intensity and color. As an environmental system, daylighting should be subjected to the same level of rigorous analysis and review that any environmental system receives. For example, increasing cooling loads and causing visual displeasure are easily occurred owing to the excessive sunlight through windows. Therefore, daylighting performance attributes and physical characteristics must be described qualitatively and quantitatively in early design process. In various architectural daylighting performance evaluation methods, the scale model experiment can be applied due to it's simplicity and usefulness. So, this study aims to evaluate the validation of scale model experiments in architectural daylighting performance. For the purpose, two scale model experiments under clear sky are conducted. And, the validation of the experiments are evaluated by computer simulations.
