Benefits of technology
This patent describes a system that uses a special nozzle to decrease the pressure of refrigerant in a refrigeration system. This helps the refrigerant to flow more easily through the system, which makes it work more efficiently. The nozzle helps to minimize energy loss during the process.
Problems solved by technology
One problem with the throttling process involving the expansion valve is that mechanical energy is wasted in reducing the refrigerant pressure.

A refrigeration system is provided that comprises a compressor, condenser, a thermal expansion valve, an isentropic expansion nozzle, and an evaporator. An isentropic expansion nozzle includes an inlet and an outlet with the isentropic expansion nozzle inlet fluidly coupled to a thermal expansion valve outlet. The evaporator includes an inlet and an outlet, wherein the evaporator inlet is fluidly coupled to the isentropic expansion nozzle outlet and the evaporator outlet is fluidly coupled to the compressor inlet. Using the system, a fluid can be modified prior to evaporation. The fluid is passed through the thermal expansion valve to decrease a pressure and decrease a temperature of the fluid. The fluid is then passed through the isentropic expansion nozzle to increase a velocity of the fluid without substantially changing the temperature of the fluid. The fluid is thereafter passed into the evaporator.
Description
FIELD OF THE INVENTION[0001]The present technology relates to using a thermal expansion valve coupled to an isentropic expansion nozzle to drop the pressure of a refrigerant and increase its flow velocity.BACKGROUND OF THE INVENTION[0002]This section provides background information related to the present disclosure which is not necessarily prior art.[0003]Heat transfer is useful for many purposes. For example, it is employed in refrigerators, air conditioning systems, vehicle HVAC systems, and the like, and can be used to liquefy gases for repeated distillation or rectification, or for storage in the liquified state. Heat transfer is further used in various devices that operate more efficiently at low temperatures. Such devices include, for example, superconductive electrical cables, cryogenic comminuting devices which embrittle a material before the milling thereof, among others. In addition, various heat transfer machines are employed to maintain materials at low temperatures to p...
