Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a cold air circulation showcase that can implement improved cold insulation performance by reducing frost formation on cold air circulation fans and an evaporator in the showcase and clogging by frost formation. SOLUTION: The showcase cools a compartment by circulating by the circulation fans 4 cold air cooled by the evaporator 5 disposed in an internal circuit. Two series expansion valves 9 and 12 and bypass lines having on/off-valves 10 and 13 connected in parallel with the respective expansion valves are interposed in high pressure refrigerant piping from a condenser of a refrigerating machine to the evaporator. The refrigerant piping between the two expansion valves is arranged upstream of the evaporator in the internal circuit. COPYRIGHT: (C)2010,JPO&INPIT
