Abstract

The world is facing environmental problems such as global warming due to the excessive use of fossil energy and energy issues, expanding the use and development of alternative energy is urgent. Energy source that can be used easily in most alternative energy source is the sun exactly. The utilization technology of solar hot water system, is a technique to be used in such hot water supply and heating and cooling of buildings absorption of the sun in the field of thermodynamic use of solar energy to use the nature of the wave of light of the sun, storage, such as through thermal conversion . However, solar hot water system, because the system energy density is very low, using the fierce energy season, changes in hourly, home heat storage technology is great importance. Heat collecting efficiency is low, flat-plate heat collector may be obtained by hot water 80 ℃ below. However, since not only hot water is used in heating of the building in winter in order to maximize the utilization of solar energy, it is insufficient to obtain the hot water in a high temperature over 100 ℃. The heat pipe is a low thermal element heat transfer capacity superior by using the latent heat of the working fluid and vacuum technology for isolating the heat loss of the external heat energy converted by the solar heat absorption plate to complement this vacuum tube solar heat collector which is applied has been developed. Integrated building and ensure the optimization technology of vacuum tube solar thermal system through analysis of various materials, evaluation, quantification, the results of the performance test of the product on the results of long-term monitoring and demonstration of Sundakorea Co., Ltd. product that stands through demonstration experiments by grasping the system right front optimum conditions through pilots solar power system to reflect the product, by increasing the reliability of products Sundakorea Co. standing attempts to spread and increase the added value of products it is believed that reduction of the electrical energy used concomitantly in that it can, to promote high performance photovoltaic systems these can, and to reduce the economic burden on consumers conveniently in a / S . In this study, the system performance of evacuated tubular solar collector was analyzed with a variable condition to compare experiment results. Through this study, the performance data and optimal control method of system performance in solar system can be provided and it will contribute to developing high efficiency solar system in solar collector.
