Store Master, our control system to optimize temperature and humidity changes in store showcases, won the 2004 Excellent Energy-Saving Device Award from the chairman of the Japan Machinery Federation.
Store Master is a system that instantaneously computes the optimum methods for operating showcases through transmission, and controls and operates inverter refrigerators installed outside for optimum energy savings. It is able to reduce motive energy of refrigerators by computing the temperature and humidity information of a store showcase, and to uniformly control all related machinery. Store Master is effective in the summer and in winter, and during periods when it is difficult to save energy, and achieves an annual average of 20-percent energy savings.
