Abstract
A refrigeration device is provided that has a compressor, a heat source side heat exchanger, and a user side heat exchanger. The refrigeration device also has a condenser arranged between the compressor and the user side heat exchanger. The condenser is arranged to condense a portion of the refrigerant that is compressed in the compressor and that is sent to the user side heat exchanger.
Claims18
A refrigeration device comprising:
- a refrigerant circuit having a compressor, a heat source side heat exchanger arranged to supply refrigerant passing through the heat source side heat exchanger to the compressor, and a user side heat exchanger arranged to receive the refrigerant that is compressed in the compressor;
- and
- a condenser arranged between the compressor and the user side heat exchanger, the condenser being configured to condense a portion of the refrigerant that is compressed in the compressor and that is sent to the user side heat exchanger,
- the refrigerant having saturation pressure characteristics that are higher than those of R407C.

A refrigeration device comprising:
- a refrigerant circuit having a compressor, a heat source side heat exchanger arranged to supply refrigerant passing through the heat source side heat exchanger to the compressor, and a user side heat exchanger arranged to receive the refrigerant that is compressed in the compressor;
- a condenser arranged between the compressor and the user side heat exchanger, the condenser being configured to condense a portion of the refrigerant that is compressed in the compressor and that is sent to the user side heat exchanger;
- and
- a check mechanism connected between the compressor and the user side heat exchanger to allow only the refrigerant to flow from the user side heat exchanger to the compressor,
- the condenser being connected to the refrigerant circuit via a branching circuit that propagates the flow of the refrigerant cut-off by the check mechanism from the compressor to the user side heat exchanger, and a junction circuit that sends the refrigerant condensed in the condenser to the user side heat exchanger.
