Abstract: Cooling systems and methods for cooling in a power plant using a phase change material. In one embodiment, a phase change material container includes at least one phase change material which may be in the form of a slurry; and at least one conduit for transporting the fluid through the phase change material when located in the phase change material container. The system may also comprise an air flow chamber; and a phase change material flow system including a pump for pumping phase change material from an outlet of phase change material container, to at least one phase change material spray nozzle. The phase change material flow system is configured to ensure that solidified phase change material is returned to the phase change material container.

Abstract: An energy efficient heat pump system capable of operating in extreme low and high temperature environments. The heat pump system includes an evaporator, a heater operatively associated with the evaporator, compressor and condenser. In an exemplary embodiment, the heat pump system may further include a plasma pulse-spark system to facilitate removal of scale deposits. The heater heats an environmental medium prior to the environmental medium exchanging energy with a refrigerant located in an evaporator coil of the evaporator in order to maintain a predetermined minimum temperature differential between the environmental medium when it contacts the evaporator coil and the refrigerant when located in the evaporator coil. The system allows efficient operation at low temperatures.
