MODEL THERMAL ENERGY STORAGE

A research was done in stages The model Thermal Storage of Solar Energy Polytechnic Kupang District. Special purpose research include: 1). To determine magnitude the temperature and pressure can be stored within 5 hours and 15 hours. 2). To determine the temperature of heat transfer the wall and beyond wall the heat the storage the container, and 3). To determine changes in the temperature and pressure each addition weights of the type collectors. From the research results first year show an increase in temperature, pressure reaches the highest point of 106 º C and 1043.5 mbar in case of addition of the collector in the storage the container with a 2:1 ratio of the weights of the collectors.
Weight gain of each type collectors is very influential on the rise in the temperature and a pressure. Coral receiving more heat stable when compared with other collectors materials, for brass and iron collectors material reception conditions are more stable heat energy and pelepasannyapun faster. As for coral receiving heat energy more slowly and release heat more quickly as well.
Indicated that at 1:30 p.m. hours the hot wall reaches 44 ° -45 ° C. This means that warm up in that area due to direct solar radiation is concentrated in the north and west wall. The walls absorb heat from direct sunlight
