This project aims 1) to study the efficiency of the panels evaporation to reduce the temperature inside the attic and 2) to compare the flow rate of water evaporation on the panel that affect the temperature inside the house attic. The work air conditioning system approach to water evaporation. The panel evaporate the water used in this experiment measures 15 cm. × 53 cm. × 25 cm., And mounting water evaporates the attic of the house model with a house model 120 cm. × 120 cm. ×. 220 cm., then take it home as a model to test 23 Science Building. Lampang Rajabhat University The house faces north. And the line thermostat, cut apples type k at various positions, including six positions on the roof, attic above the ceiling, loft, home and environment. Data recorded by the Data Logger records data every 30 minutes from 9.00 am - 16.00 pm. The study panel performance evaporation to reduce the temperature of the attic apartment. Found that the average temperature of the attic before mounting evaporation of 36.9 ° C and after installation, with an average temperature of 30.9 ° C, which is the difference between the average temperature before and after was 6.0 ° C, compared to the flow rate. of water on the panel, evaporation, affecting the attic temperature that water pressure at 8 liters per minute resulted attic temperatures decreased the most with an average temperature of 30.9 ° C, followed by the class. The water pressure at 6 liters per minute and 4 liters per minute, with an average temperature of 31.3 ° C and 35.8 ° C respectively, bringing the volatility panel applied to the house attic. Another alternative is to lower the temperature inside the home and is one of the ways to save energy.
