태양열 온수기 이용 냉난방시스템의 운전특성에 관한 연구

Abstract

Recently, according to the superior quality of building facility environment with the elevation of living standard, the use of air-conditioner for improvement of dwelling place is increasing. So, a phenomenon of electric power peak impose burden on policy on the demand and supply of energy. In the winter, hot water gained from the solar collector installed on the roof could have a wide usage for replacing a conventional air conditioner. The aim is to adopt a new device into a all-terrian system enable to perform heating and cooling effect. First of all, several different experiments were conducted for investigating the possibility of actual heating system mainly being operated by solar collector and regenerator. The experimental apparatus was fabricated and tested practically in connection with solar heating system during daytime. As a result, it was clear that this system has many advantages of heating and humidifying of room without a huge heater and humidifier, especially in winter and can save a lot of electricities compared to a conventional air conditioner. And in the summer, hot water gained from the solar collector installed on the roof could have a wide use as a heat source for replacing a conventional air-conditioner by combining some devices. One of those is to adopt it into a solar desiccant cooling/heating system enable to generate the heating and cooling effect through the two processes. One is for regenerating and the other for dehumidifying process. In this experiment, two devices for each process purpose were fabricated and installed in the mechanical room. The experiments were conducted with 4 sheets solar collectors and both processes of regenerating and dehumidifying were operated outside simultaneously under fine weather. The results of its performance were described.
