In the present work the performance of a cold room with a novel air heat exchanger containing PCM (Phase Change Material) was experimentally investigated. Specifically, an air heat exchanger consisting of aluminium containers with finned surface filled with PCM (5 °C melting temperature), was located near the evaporator of a cold room. The aims are to reduce cooling energy consumption and improving the maintenance thermal conditions of stored products. For this purpose, an experimental campaign was carried out and a monitoring system was developed. The cold room thermal behaviour, with and without PCM, was studied under steady state operating conditions. As expected a reduced number of on/off compressor cycles (6 cycles instead 13 cycles) in the PCM added cold room was observed. Test results showed that by storing PCM in the air heat exchanger, up to 16% of energy saving can be achieved.

Abstract
In the present work the performance of a cold room with a novel air heat exchanger containing PCM (Phase Change Material) was experimentally investigated. Specifically, an air heat exchanger consisting of aluminium containers with finned surface filled with PCM (5 °C melting temperature), was located near the evaporator of a cold room. The aims are to reduce cooling energy consumption and improving the maintenance thermal conditions of stored products. For this purpose, an experimental campaign was carried out and a monitoring system was developed. The cold room thermal behaviour, with and without PCM, was studied under steady state operating conditions. As expected a reduced number of on/off compressor cycles (6 cycles instead 13 cycles) in the PCM added cold room was observed. Test results showed that by storing PCM in the air heat exchanger, up to 16% of energy saving can be achieved.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
