Abstract:

This object presents anew analysis of peak load shifting for air conditioning system using PCM (phase changematerial) in a room. The gentle range of the used PCM is from 20 to 25°C. The amount of the PCM is resoluteaccording to the cooling load of the room during the peak time. The hourly cooling load is considered. A low-power fanis used to drive air over the PCM capsules, which are decided in a chamber above the room. Auxiliary cooling unit isused to suspension the PCM when the night temperature is higher than 18°C. The temperatures of the PCM are restrained by9 thermocouples inserted inside a capsule. The different degrees of temperature of the air at the inlet, at the middle, and atthe outlet of the air-passing chamber as well as at the room are dignified during day and night. In addition to that, theclimate conditions are measured. As a result, during the peak load shifting time, which is within 2 hours, the decrease ofthe room temperature is between 7-10 °C by using PCM ceiling system. Accordingly, it can be concluded that the PCMsystem is effective for the peak load shifting.

Keywords:
