Abstract
In a gas-liquid separator for an ejector cycle, a tank body is constructed such that a refrigerant sprayed from a refrigerant inlet forms a spiral stream in the tank body. The tank body has a horizontal longitudinal axis greater than a vertical axis. The refrigerant inlet is located at a distance from the horizontal longitudinal axis of the tank body such that the refrigerant sprayed from the refrigerant inlet generates a turning force and spirally flows. With this, a gas-liquid separation distance of the refrigerant increases.
Claims25
A gas-liquid separator for an ejector cycle that includes an ejector for drawing gas refrigerant from an evaporator by decompressing refrigerant then increasing pressure of refrigerant to be sucked into a compressor, the gas-liquid separator comprising:
- a tank body for separating refrigerant into gas refrigerant and liquid refrigerant, the tank body defining a refrigerant inlet through which the refrigerant is discharged into the tank body from the ejector, a gas refrigerant outlet through which the gas refrigerant is discharged toward the compressor and a liquid refrigerant outlet through which the liquid refrigerant is discharged toward the evaporator, wherein:
- the tank body has a horizontal axis longer than a vertical axis;
- and
- the tank body is constructed such that the refrigerant flows spirally about the horizontal axis throughout the tank body.
A gas-liquid separator for an ejector cycle including an ejector, the gas-liquid separator comprising:
- a tank body for separating refrigerant into gas refrigerant and liquid refrigerant, the tank body including a substantially cylindrical wall portion having a horizontal longitudinal axis and first and second end surfaces, and the tank body defining a gas refrigerant outlet through which the gas refrigerant flows out of the tank body and a liquid refrigerant outlet through which the liquid refrigerant flows out of the tank body;
- and
- a refrigerant inlet pipe communicating the tank body with the ejector,
- wherein the refrigerant inlet pipe defines a refrigerant opening at its end, the refrigerant opening being opened inside the tank body such that refrigerant discharged from the opening is sprayed to form a spiral stream about the horizontal longitudinal axis throughout the tank body.
A gas-liquid separator for an ejector cycle that includes an ejector for drawing gas refrigerant from an evaporator by decompressing refrigerant, the gas-liquid separator comprising:
- a tank body for separating refrigerant into gas refrigerant and liquid refrigerant, the tank body defining a refrigerant inlet through which the gas refrigerant and the liquid refrigerant are discharged into the tank body from the ejector, a gas refrigerant outlet through which the gas refrigerant is discharged toward the compressor and a liquid refrigerant outlet through which the liquid refrigerant is discharged toward the evaporator,
- wherein the tank body is constructed such that the gas refrigerant and the liquid refrigerant flow throughout the tank body.
