Abstract

It was studied on the condensation system using solar distillation in the cubes tilted with 60˚, 45˚, 30˚, 15˚of glass. The temperatures in the cube and solar radiation, weather condition and the amount of condensed water were measured for two years and The amopunt of condensed water was analysed with the season and weather condition, and concluded as follows:

Spring 1. When sunshine wasn't measured from 17 to 20 o'clock, lots of condensed water was produced. 2. The condensed water was produced more 15˚and 30˚than 60˚and 45˚on clear day. 3. The condensed water was produced more clear day than yellow dust day. 4. When the upper part of inner temperature was lower than the lower part of inner temperature, lots of condensed water was produced.

Summer 1. Lots of the condensed water was produced in case of 15˚, same as clear day of spring. 2. The Sunshine wasn't measured little, but outside temperature was higher than other season on rainy day. 3. Lots of the condensed water was produced in case of 60˚on rainy day. 4. The condensed water was produced irregularly and the most condensed water was produced in case of 60˚on shower day.

Autumn 1. The condensed water was produced more 45˚and 60˚than 30˚and 15˚on clear day. 2. Lots of condensed water was produced in case of 15˚, 30˚on clear day of spring and summer, but It was produced in case of 45˚and 60˚.

Winter 1. The sunshine was measured more than summer, but outside temperature was lower than other season on clear day. 2. Lots of the condensed water was produced in case of 45˚and 60˚, same as clear day of autumn.

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 2000 ㎖ 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 ㎖.
