REFRIGERATING DEVICE
Document Type and Number:
Japanese Patent JP2008275195
Kind Code:
A
Abstract:
To surely prevent flowing of a refrigerant to use-side heat exchangers 51a, 51b, 51c in thermo-off, and to prevent increase in dimension of electronic expansion valves 52a, 52b, 52c, in a refrigerating device comprising the plurality of use-side heat exchangers 51a, 51b, 51c and the electronic expansion valves 52a, 52b, 52c of variable openings corresponding to the use-side heat exchangers.
Opening and closing valves 53a, 53b, 53c settable at two positions of an open position and a fully-closed position, are disposed on one side of an upstream side and a downstream side of the electronic expansion valves 52a, 52b, 52c in a refrigerant pipe.
