Abstract
A system for desuperheating hot gaseous refrigerant using both a heat exchanger and a dispersed Venturi-driven injection of liquid refrigerant is disclosed. Further, a system, relating to cooling at least one compressed superheated refrigerant fluid prior to condensing, relating to extending the life of at least one condenser is disclosed.
Claims42
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;
- and
- e) wherein said at least one suction creator assists injection by said at least one injector.

A method, relating to cooling at least one superheated refrigerant fluid during at least one heat cycle, the method comprising the steps of:
- a) exchanging heat, in at least one heat exchanger, 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) injecting, using at least one injector, the at least one cooling fluid into the at least one superheated refrigerant fluid after the step of exchanging heat;
- c) mixing 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;
- and
- d) creating suction to draw the at least one cooling fluid into the at least one heat exchanger by decreasing localized pressure near the at least one injector;
- e) wherein the suction assists injection by such at least one injector.

- c) fluid mixer means for mixing 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 heat exchanger means comprises suction creator means for creating suction to draw the at least one cooling fluid into said heat exchanger means by decreasing localized pressure near said injector means;
- and
- e) wherein said suction creator means assists injection by said injector means.

A method, relating to cooling at least one superheated refrigerant batch during at least one heat cycle, such method comprising the steps of:
- a) creating suction to draw at least one cooler refrigerant batch into heat exchange relationship with such at least one superheated refrigerant batch;
- b) exchanging heat between the at least one superheated refrigerant batch and at least one cooler refrigerant batch to decrease temperature differential between the at least one superheated refrigerant batch and the at least one cooler refrigerant batch and form at least one cooler superheated refrigerant batch;
- c) injecting the at least one cooler refrigerant batch into the at least one cooler superheated refrigerant batch after the step of exchanging heat;
- and
- d) mixing the at least one cooler refrigerant batch and such at least one cooler superheated refrigerant batch to produce at least one desuperheated refrigerant batch having at least one portion substantially near at least one saturated state.
