Abstract
Systems and methods for regenerative ejector-based cooling cycles that utilize an ejector as the motivating force in a cooling loop to regeneratively sub-cool a refrigerant in a single-stage cooling cycle.
Claims17
A system for use with a refrigerant in a regenerative cooling cycle, which comprises:
- an ejector for mixing a condensed liquid form of the refrigerant and a first vaporized form of the refrigerant to form a two-phase form of the refrigerant;
- a flash economizer in fluid communication with the ejector for separating the two-phase form of the refrigerant from the ejector into a second vaporized form of the refrigerant and a liquid form of the refrigerant;
- a sub-cooler connected to the ejector by a vaporized refrigerant line for cooling a portion of the liquid form of the refrigerant from a liquid refrigerant line fluidly connected to the flash economizer and vaporizing another two-phase form of the refrigerant;
- and
- an evaporator in fluid communication with the sub-cooler for heating a separate sub-cooled liquid form of the refrigerant by transferring heat from an external source to the separate sub-cooled liquid form of the refrigerant and producing a third vaporized form of the refrigerant, wherein the flash economizer is connected to the evaporator for receiving the third vaporized form of the refrigerant.
