System Independent Refrigerant Control System

摘要

The present invention provides a system independent valve used in a refrigeration cycle in place of a typical pressure reducing expansion valve or capillary tube. The system independent valve will regulate saturated liquid flow enroute to the evaporator by introducing a controlled ultrasonic crystal pulse within the valve. The controlled excitation will form pressure waves and vapor pockets that result in vapor sonic velocity at the valve which is variable.

主权项

1) A valve assembly for use in a refrigerant control system, comprising
a) a capillary tube having a first end and a second end; b) a wave propagating casing encapsulating a portion of said capillary tube between said first and second ends; c) a resonant piezo assembly operable at a predetermined frequency attached to said wave propagating casing; and d) a conductive wire for transmitting electrical energy to said resonant piezo assembly, whereby said resonant piezo assembly induces vibration in said wave propagating casing and said capillary tube.
