Estimating the term…
A refrigerating or heat pump system includes an evaporator (23), a compressor (20), an air-cooled heat rejecting heat exchanger (21) and an expansion device (22) being connected in a closed circuit and operating in a trans critical vapor compression cycle. The heat rejecting heat exchanger (21) is cooled by natural upwards circulation/convention of air. In a preferred embodiment the heat rejecting exchanger (21) is built into an air flow conduit or shell (11) to improve the natural air circulation by obtaining a chimney effect.
A refrigerating or heat pump system including at least one of each following components, an evaporator (23), a compressor (20), an air-cooled heat rejecting heat exchanger (21) and an expansion device (22), connected in a closed circuit operating in a vapor compression cycle, characterized in that the refrigerant rejects heat at a supercritical pressure with gliding temperature through the heat rejecting heat exchanger (21) which is cooled by natural upwards circulation/convection of air.
