Abstract

An expansion device for refrigeration system having a piston which reciprocates to either open or close ports to increase or decrease the volume of atomized refrigerant liquid received from the condenser. Atomization may be enhanced by use of auxiliary ultrasonic or electrostatic atomization devices.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

The above and other objects of the present invention will be more fully understood from the following description, claims and drawings in which:

FIG. 1 is schematic showing a representative of refrigeration circuit with the valve of the present invention installed therein;

FIG. 2 is a cross-sectional view showing the expansion device of the present invention;

FIG. 3 is a detail view showing an alternate valve configuration for the orifices;

FIG. 4 is a schematic view of an alternate embodiment in which the expansion device incorporates an electrostatic atomizing device;

FIG. 4A is a section along line

4A—

4A of FIG. 4; and

FIG. 5 shows a schematic view of yet another embodiment in which the expansion device incorporates an ultrasonic atomizing device.

Claims

1. A device for expanding and vaporizing refrigerant in a compression refrigeration system of the type having a compressor, condenser and evaporator, said device comprising:

2. The device of claim 1 wherein said drive means comprises a stepper motor.

3. The device of claim 1 wherein said stepper motor is operated by a temperature sensor sensing pressure at a location in the system.

4. The device of claim 1 wherein said orifices comprise a plurality of removable nozzles.

5. The device of claim 1 further including ultrasonic atomization means communicating with said valve chamber.

6. The device of claim 1 further including electrostatic atomization means communicating with said valve chamber.

7. A device for expanding and vaporizing refrigerant in a compression refrigerator system of the type having a compressor, condenser and evaporation in closed communication, said device comprising an electrostatic atomization device interposed between said condenser and evaporator.
