태양열을 받는 경사진 육면체의 날씨에 따른 응축특성에 관한연구

Abstract

The cubes tilted angle of 15˚, 30˚, 45˚, 60˚, the base area 1000 mm×1000 mm had been fabricated to get the data for solar condensed water system and were studied the optimum size and tilted angle of cube for distillation and condensation and concluded as follow:

In case of the clear day 1. In case of clear day, the cube of tilted angle 45˚was the best for condensation water produced by 1207㎖ and required base area of water for a man needed 2000ml for one day was 1.6㎡. 2. After three hours from sunset, the amount of condensation water was the largest. 3. When the tilted angle is the bigger, the gap rate is bigger, it takes long time to get the saturation temperature and condensation. In case of the cloudy day 1. In case of cloudy day, the cube of tilted angle 45˚was the best for condensation water produced by 900 ㎖ and required base area of water for a man needed 2000 ㎖ for one day was 2.2 ㎡.

In case of the rainy day 1. In case of rainy day, the cube of tilted angle 45˚was the best for condensation water produced by 1047 ㎖ and required base area of water for a man needed 2000 ㎖ for one day was 1.9 ㎡.

In case of the snowy day 1. In case of rainy day, the cube of tilted angle 45˚was the best for condensation water produced by 392 ㎖ and required base area of water for a man needed 2000 ㎖ for one day was 6.1 ㎡. 2. The evaporation wasn't occur because the temperature was low and solar radiation was less measured in a heavy snow day, so the condensation water was produced a little such as, 60˚was 343 ㎖, 45˚was 330 ㎖, 30˚was 265 ㎖, and 15˚was 248 ㎖.

In case of the irregular day 1. When the shower day after clear tilted angle of 60˚produced the largest than that of 45˚because of big gap rate.

Required base area of water 1. The required the area per one man in clear day for one year was 1.66 ㎡ for the tilted angle 45˚. 2. The required base area per one people needed 2000 ㎖ for one day on May, June July, August and September was 2.22 ㎡ for June produced minimum of 1047 ㎖.
