Summary
An ice pond system with a 200 m3 ice pond was operated to refrigerate a storage warehouse, and heat transfer through the surfaces of the ice pond and the heat gain by storage cooling were measured and calculated by heat transfer analysis. The calculated values of heat transfer agreed with the measured ons. During the ice storage, the heat gain through the top surface of ice mass was about three fourths that of the total, and too large in comparison with the heat from the side slopes and bottom. It showed that the improvement of insulation on this surface is the most important and effective to control ice melting. The heat gain through the aboveground part of side slopes was relatively greater than both of the underground part and the bottom of the ice pond. The cooling with the ice pond was feasible until the end of August. Though a small percentage of the total energy of produced ice was used effectively for storage cooling in the experimental facilities, the a11alysis proved that the energy extraction efficiency increases in proportion with cooling capacity per top surface area of ice.HomePageKeywords: ice pond, ice, heat load, heat transfer, refrigeration, storage
