Summary

In this study, we focused on the way of waste heat utilization to supercooling in refrigerated cabinet(s) by cold heat of PCM (Phase change material) in the case of supermarket fields. In this experiment, we installed a heat exchanger after the condenser of the refrigerated cabinet to control the supercooling degree using the PCM cold storage tank. We changed supercooling water flow rate
throughout the year to measure and compare the supercooling degree and power consumption of each season. We measured the energy conservation effect of supercooling by PCM in the refrigerated cabinet(s). As the result of this experiment, the exhaust heat utilization to supercooling by PCM was effective for energy conservation in the summer and the intermediate seasons. On the other hand, we confirmed that the effect of supercooling by PCM could be lost when the outside temperature was 16 Celsius and below.
