Abstract
A transcritical vapor compression system that includes a fluid circuit circulating a refrigerant in a closed loop. The fluid circuit has operably disposed therein, in serial order, a compressor, a first heat exchanger, a first capillary tube and a second heat exchanger. The compressor compresses the refrigerant from a low pressure to a supercritical pressure. The first heat exchanger is positioned in a high pressure side of the fluid circuit and the second heat exchanger is positioned in a low pressure side of the fluid circuit. The first capillary tube reduces the pressure of the refrigerant from a supercritical pressure to a relatively lower pressure. The refrigerant flows through the first capillary tube at its critical velocity and means for controlling the temperature of the refrigerant in the first capillary tube are provided.
