Document Type and Number:
WIPO Patent Application WO/2019/242507
Kind Code:
A1
Abstract:
Provided in the present invention is a heat and cold energy separation method for separating a sensible heat of water from a latent heat of ice employing sublimation and evaporation in a vacuum. The method comprises: establishing a vacuum environment in an artificial environment, evaporating a portion of liquid entering therein, and solidifying a portion of liquid, wherein a portion of the solid can further be sublimated; separating the vapor from the solid, wherein the solid or solid-liquid mixture becomes cold energy for output, and the vapor becomes heat energy for output. The process continues to proceed, realizing the separation of cold and heat energies. The present invention makes use of the vacuum technology and the physical properties of water to realize the heat and cold energy separation and further realize the storage and usage thereof, which can greatly improve the system efficiency and COP value on the basis of the existing refrigerating and heating technologies. Further provided in the present invention is an apparatus for implementing said method. In addition, the present invention further provides equipment for applying said apparatus in seawater desalination, low-temperature power generation, heating, and refrigeration.
