Systems and methods of using phase change material in power plants
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.
1. A cooling system for cooling a fluid comprising: a heat exchanger comprising a recirculating mesh including a plurality of encapsulated phase change material meshes each including a plurality of encapsulated phase change material particles, and a cable driven by a device for moving the recirculating mesh between the fluid and an airflow chamber in a manner whereby some of said modules are positioned for heat exchange with said fluid and some of said modules are positioned for heat exchange with an air flow in said cooling system, wherein heat is transferred from the fluid to the encapsulated phase change material particles to melt at least some of the encapsulated phase change material particles to provide encapsulated liquid phase change material.
2. The cooling system of claim 1 , comprising a plurality of recirculating meshes.
3. The cooling system of claim 2 , wherein the plurality of recirculating meshes radiate from a central location within a cooling tower.
4. A cooling system for cooling a fluid comprising:
a heat exchanger including a plurality of encapsulated phase change material modules each including a plurality of encapsulated phase change material particles;
a rotating structure that rotates about a vertical axis for moving said modules in a manner whereby some of said modules are positioned for heat exchange with said fluid and some of said modules are positioned for heat exchange with an air flow in said cooling system,
wherein heat is transferred from the fluid to the encapsulated phase change material particles to melt at least some of the encapsulated phase change material particles to provide encapsulated liquid phase change material.
