Abstract (en)
A refrigerator (10) has a compressor (12), a gas cooler (14), an expansion valve (16), and an evaporator (18) connected in this order by a refrigerant pipe (20) and opens and closes an electromagnetic valve (26) provided in a bypass pipe (22) serving as a bypass section that connects the outlet side and the inlet side of the compressor (12). An electromagnetic-valve control device (30) opens the electromagnetic valve (26) if the pressure of a refrigerant at the outlet of the evaporator (18) during operation of the compressor (12) becomes lower than or equal to an ON threshold value set with reference to the triple point of the refrigerant. Accordingly, the electromagnetic-valve control device (30) can allow the refrigerator (10) to continue operating without having to stop the compressor (12) even when a physical quantity of the refrigerant approaches the triple point.
