Heat pump energy storage system
Phase Change Materials (PCM) store and release thermal energy during the process of melting & freezing and the latest range of PCM solutions between -100°C and +885°C offer new application opportunities.
For example, using +8°C and +46°C PCM materials on both cold and hot side of the heat pump would spread the loads over 24 hours and reduce the machine size as much as by 50%. By also storing both hot and cold sides the overall COP nearly doubles not only reducing the running cost but also offers reliable and stand-by capacity system.
