Refrigeration machine for transportation

Abstract

A refrigeration machine (10) for transportation comprises: a compressor (11) that compresses a refrigerant; an external heat exchanger (12) that performs heat exchange between the refrigerant and external air; a first internal heat exchanger (13) that performs heat exchange between the refrigerant and internal air; a second internal heat exchanger (14) that performs heat exchange between the refrigerant and the internal air; a sixth refrigerant pipe (L6) that guides the refrigerant discharged from the compressor (11) to the first internal heat exchanger (13) in a drying operation mode; a drying operation expansion valve (16) that expands the refrigerant discharged from the first internal heat exchanger (13) in the drying operation mode; a seventh refrigerant pipe (L7) that guides the refrigerant expanded by the drying operation expansion valve (16) to the second internal heat exchanger (14) in the drying operation mode; an eighth refrigerant pipe (L8) that guides the refrigerant expanded by the drying operation expansion valve (16) to the external heat exchanger (12) in the drying operation mode; and a ninth refrigerant pipe (L9) that guides the refrigerant discharged from the external heat exchanger (12) to the compressor (11) in the drying operation mode.
