Title: Cooling device
Inventor: KOBAYASHI MAKOTO
IPC: F25B9/00
Filed: 2002-05-16
Abstract: <P>PROBLEM TO BE SOLVED: To provide a cooling device capable of continuing cooling operation without discharging a carbon dioxide refrigerant even when a refrigerant in a secondary side refrigerating circuit exceeds a specified pressure or a specified temperature.  <P>SOLUTION: When the refrigerant pressure in the secondary refrigerating circuit 2 exceeds a specified upper limit pressure (when a refrigerating capacity is short due to an increase in load of the secondary refrigerating circuit 2), an open/close valve is closed. Thus, though the supply of the refrigerant to an evaporator 23 is stopped, the refrigerant remaining in the evaporator 23 performs heat exchange to continue to cool a load. Then, the amount of the remaining refrigerant is gradually reduced to lower the refrigerant pressure in the secondary refrigerating circuit 2. When the refrigerant pressure becomes a lower limit pressure during the lowering of the pressure, the open/close valve 2 is opened. Thus, the refrigerant is circulated in the secondary refrigerating circuit 2 to cool the load. Thus opening and closing of the open/close valve 22 is repeated to cope with the high load on the secondary refrigerating circuit 2.  <P>COPYRIGHT: (C)2004,JPO
