REfrigant cycle

The is the heart of the vapor-compression refrigeration cycle,

Low-pressure, low-temperature, superheated refrigerant enters the compressor and is compressor

changing it to a high-pressure, high-temperature, superheated

It then moves to the condenser where some of the heat is removed, de-superheating and condensing it into a

It then flows to the metering or expansion device as a high-pressure, subcooled liquid.

Before it leaves the condenser as a high-pressure liquid, the liquid refrigerant is to a point below the liquid saturation temperature

As the refrigerant flows through the metering device, the pressure of the liquid is , causing a small percentage of the liquid to flash to a vapor (flash-gas), lowering the temperature of the remaining refrigerant to its saturation temperature.

causing a small percentage of the liquid to flash to a (flash-gas), lowering the temperature of the remaining refrigerant to its saturation temperature.

The low-pressure, low-temperature refrigerant flows into the as a low-temperature saturated refrigerant.

As the refrigerant absorbs heat, it evaporates into a low-temperature
