Abstract:
1. An air-refrigerant cooling apparatus comprising: a compressor compressing refrigerant air; a water-cooled heat exchanger cooling said refrigerant air discharged from said compressor through heat exchange with water; an exhaust heat recovery heat exchanger cooling said refrigerant air discharged from said water-cooled heat exchanger; an expansion turbine expanding said refrigerant air discharged from said exhaust heat recovery heat exchanger; a defroster removing moisture from said refrigerant air discharged from said expansion turbine; a cooled chamber supplied with said refrigerant air from said defroster, said refrigerant air discharged from said cooled chamber being supplied to said compressor through said exhaust heat recovery heat exchanger to provide heat exchange between said refrigerant air discharged from said water-cooled heat exchanger and said refrigerant air discharged from said cooled chamber; a cooled chamber bypass pipe allowing said refrigerant air discharged from said defroster to bypass said cooled chamber and to enter a pipe connected to an outlet of said cooled chamber; and a defrosting bypass pipe branched from a pipe connected between said water-cooled heat exchanger and said exhaust heat recovery heat exchanger to supply said defroster with said refrigerant air discharged from said water-cooled heat exchanger.
