Abstract
An improvement in a refrigeration circuit comprising a hermetic chamber (10), which is maintained in fluid communication with the refrigeration circuit, immediately downstream at least one of the parts defined by a condenser (5) and by a hermetic compressor (1), and which is dimensioned to store, in conditions of long stops of the hermetic compressor (1) and of a start thereof, a substantial volume of refrigerant fluid, said hermetic chamber (10) returning to the refrigeration circuit substantially all the refrigerant fluid stored therein, after said conditions have ended.
Claims15
An improvement in a refrigeration circuit, including:
- a hermetic compressor (1) having a shell (2);
- and a condenser (5) having an inlet (6) connected to a discharge outlet of the hermetic compressor (1) and an outlet (7), characterized in that it comprises a hermetic chamber (10), which is maintained in fluid communication with the refrigeration circuit, immediately downstream at least one of the parts defined by the condenser (5) and by the hermetic compressor (1), and which is dimensioned to store, in conditions of long stops of the hermetic compressor (1) and of a start thereof, a substantial volume of refrigerant fluid, said hermetic chamber (10) returning to the refrigeration circuit substantially all the refrigerant fluid stored therein, after said conditions have ended.
An improvement in a refrigeration circuit, comprising:
- a hermetic compressor having a shell;
- a condenser comprising:
- an inlet connected to a discharge outlet of the hermetic compressor;
- and
- an outlet comprising a hermetic chamber, which is maintained in fluid communication with the refrigeration circuit, immediately downstream at least one of the parts defined by the condenser and by the hermetic compressor, and which is dimensioned to store, in conditions of long stops of the hermetic compressor and of a start thereof, a substantial volume of refrigerant fluid;
- the hermetic chamber returning to the refrigeration circuit substantially all the refrigerant fluid stored therein, after the conditions have ended, wherein the hermetic chamber is dimensioned to receive all the refrigerant fluid in the liquid state;
- the hermetic chamber having a tubular body in which is provided an inlet and an outlet of refrigerant fluid, the inlet being provided in an upper portion of the tubular body;
- the hermetic chamber is provided downstream of the hermetic compressor, through a respective supply duct provided in a circuit parallel to said refrigeration circuit and which defines, simultaneously, the inlet and the outlet of the hermetic chamber;
- and
- the inlet of the hermetic chamber is provided above a maximum filling limit of the hermetic chamber with the refrigerant fluid in the liquid state.
