Abstract

With respect to the critical circumstances of watering resources in Mashhad and other cities of Iran and also the importance of reasonable consumption of fresh water which is used in large amount in watering cooler in warm periods, we intended to examine the rate of water usage by watering cooler in iwo condition of sunshine and shadow. Two watering cooler were fixed in the same environmental and physical condition. The first cooler was under the shadow of light roof the second one was in free access to the sunshine. Temperature and the moisture levels measured before and after examination in both condition and the water usage was evaluated too. The result showed that water usage of the cooler in the shadow was more than 10 percent lower the other one. Although the temperature and the moisture levels was the same in both conditions but these parameters’ levels were a little more in the cooler which was in shadow.
