A non-azeotropic mixed refrigerant containing carbon dioxide is used as the refrigerant.

The refrigerant distribution assembly (20, 420) receives a refrigerant that enters the shell ( 10) and discharges the refrigerant.

A receiver (50) is provided for collecting a refrigerant flowing through a refrigerant flow circuit.

Disclosed is an evaporator wherein a refrigerant introduced from a refrigerant inlet (14) is guided to a refrigerant outlet (15) while being evaporated.

A refrigerant circulates in an evaporation stage in a refrigeration circuit.

The used refrigerante R12 is known as a safety refrigerant.

The reservoir separates the liquid phase and gas phase of said refrigerant.

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 system also includes a reservoir with an inner cavity, a refrigerant supply conduit, and a refrigerant return conduit.

An air conditioner where, in refrigerant charging performed by using a refrigerant container, the fact that the refrigerant container is empty can be known without using a weigher etc.

Instead of the given refrigerant for which the pressure-relief valve (2) is adjusted, a refrigerant with a low evaporation temperature is used.

A refrigerator has a pressure-relief valve (2) which is adjusted for a given refrigerant.

Refrigerant circulates though the closed circuit vapor compression system.

  A refrigerant is sucked into the cylinder chamber from the suction hole.

A refrigeration cycle device (1) has a refrigeration circuit in which refrigerant circulates.
