超臨界圧での熱除去を用いる冷凍またはヒートポンプシステム
Document Type and Number:
Japanese Patent JP2004514868
Kind Code:
A
Abstract:
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.
