SEALED TYPE COMPRESSOR AND REFRIGERATION CYCLE

摘要

PROBLEM TO BE SOLVED: To improve safety of a sealed type compressor and a refrigeration cycle using a combustible saturated hydrocarbon as a refrigerant by reducing the leaking amount thereof. SOLUTION: The sealed type compressor 401 comprises in a well-closed container 2 pre-cooler outlet and inlet side valves 102 and 104 respectively for closing pre-cooler outlet and inlet pipes 12 and 16 when it stops operation to shut off a pre-cooler therefrom, so that it is possible to prevent a refrigerant in the well-closed container 2 from leaking out of the pre-cooler and reaching in density the explosion limit.
