Title:
GAS REFRIGERANT SEPARATOR, GAS REFRIGERANT SEPARATOR-CUM-REFRIGERANT FLOW DIVIDER, EXPANSION VALVE, AND REFRIGERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/040286
Kind Code:
A1
Abstract:
A gas refrigerant separator-cum-refrigerant flow divider (DR) is provided with: an introduction chamber (10) having a circular cross-section; a speed increase chamber (20) having a circular cross-section; and a delivery chamber (30) having a circular cross-section, and the chambers (10, 20, 30) are disposed serially and coaxially. The delivery chamber (30) introduces therein a refrigerant from a refrigerant introduction opening (14) along the inner wall surface of the chamber and swirls the refrigerant. The speed increase chamber (20) increases the speed of the swirl flow of the refrigerant flowing into the speed increase chamber (20) from the introduction chamber (10), and discharges the refrigerant from a communication opening (21), which is located at the front end of the speed increase chamber (20), to the delivery chamber (30). The delivery chamber (30) has a diameter greater than the diameter of the communication opening (21) at the front end of the speed increase chamber (20). Also, the gas refrigerant separator-cum-refrigerant flow divider (DR) is provided with a gas refrigerant extraction pipe (Pg) for extracting a gas refrigerant from the center of the swirling refrigerant flow, and a refrigerant delivery pipe (Pd) for delivering the refrigerant from which the gas refrigerant has been extracted.
