The material combines Group I and II halides with silica gel. This is then placed around a finned heat exchanger, housed in a porous drainage pipe. The device permits the heat pump to extract and store heat from ground and air via the dynamic exchange of water between soil solution, water vapor, and phase change material. The design reduces inefficiencies in the heat pump, enables load shifting, and saves electricity.The phase change materials are made from halides, compounds of a halogen such as fluorine, chlorine, bromine and iodine. This is the only group in the periodic table that contains elements in all three states of matter (solid, liquid, and gas) at standard temperature and pressure. When such materials change from solid to liquid and back again, they are capable of storing and releasing large amounts of energy.
