Patent ID: 7958739

Claim:
A system, relating to cooling at least one superheated refrigerant fluid during at least one heat cycle, the system comprising: a) at least one heat exchanger structured and arranged to exchange heat between at least one cooling fluid and the at least one superheated refrigerant fluid to decrease temperature differential between the at least one cooling fluid and the at least one superheated refrigerant fluid; b) at least one injector, structured and arranged to inject the at least one cooling fluid into the at least one superheated refrigerant fluid after exchange of heat in said at least one heat exchanger; and c) at least one fluid mixer structured and arranged to mix the injected cooling fluid and the at least one superheated refrigerant fluid to produce at least one desuperheated refrigerant fluid having at least one state substantially near at least one saturated state; d) wherein said at least one heat exchanger comprises at least one suction creator structured and arranged to create suction to draw the at least one cooling fluid into said at least one heat exchanger by decreasing localized pressure near said at least one injector; e) wherein said at least one suction creator comprises at least one draw regulator structured and arranged to regulate the draw to prevent overcooling of the at least one superheated refrigerant fluid, when flow rate of the at least one superheated refrigerant fluid changes; and f) wherein said at least one suction creator assists injection by said at least one injector.
