Abstract
A cooling circuit through which coolant flows, for use with a refrigerated cabinet. The cooling circuit includes a compressor and a condenser with a flow path extending there between. The cooling circuit also includes an evaporator and a second flow path that extends between the evaporator and the condenser. The cooling circuit additionally includes a suction accumulator and a flow path extending between the evaporator and the suction accumulator, while a fourth flow path extends between the suction accumulator and the compressor. The cooling circuit also includes a coolant bypass and a switch that switches the cooling circuit between a cycling mode and a non-cycling mode.
Claims11
A cooling circuit through which coolant flows, for use with a refrigerated cabinet, comprising:
- a compressor;
- a condenser, wherein a first flow path extends between said compressor and said condenser;
- an evaporator, wherein a second flow path extends between said condenser and said evaporator;
- a suction accumulator, wherein a third flow path extends between said evaporator and said suction accumulator and wherein a fourth flow path extends between said suction accumulator and said compressor;
- a coolant bypass that extends between said first flow path and said second flow path, wherein said coolant bypass comprises a fifth flow path and a flow control valve;
- and
- a switch that switches the cooling circuit between a cycling mode and a non-cycling mode.
A cooling circuit through which coolant flows, for use with a refrigerated cabinet, comprising:
- means for providing a cooling circuit through which coolant flows, comprising:
- a compressor;
- a condenser, wherein a first flow path extends between a said compressor and said condenser;
- an evaporator, wherein a second flow path extends between said condenser and said evaporator;
- a suction accumulator, wherein a third flow path extends between said evaporator and said suction accumulator and wherein a fourth flow path extends between said suction accumulator and said compressor;
- a coolant bypass that extends between said second flow path and said first flow path, wherein said coolant bypass comprises a fifth flow path and a flow control valve;
- and a switch that switches the cooling circuit between a cycling mode and a non-cycling mode;
- means for selecting a desired air temperature for the refrigerated cabinet;
- and
- means for selecting an operating mode from the cycling mode and the continuous mode using the switch.
