ABSTRACT:
A PCM system and method of shifting peak electrical load is provided with a PCM system including a heat exchanger, a storage tank coupled to the heat exchanger for storing PCM slurry, a pump coupled to the heat exchanger, an air conditioning unit coupled to the heat exchanger, and a heat rejection unit coupled to the storage tank. The PCM slurry is pumped from the storage tank to the heat exchanger. The energy at the heat exchanger is absorbed by the PCM slurry, and the PCM slurry is then returned to the storage tank. The energy absorbed by the PCM is rejected from the storage tank to a ground loop or by an air conditioning unit during a non-peak or less load demand period.
