Document Type and Number:
Japanese Patent JP2011038729
Kind Code:
A
Abstract:
To obtain intended refrigerating capacity, while obeying the filling amount regulation of a combustible refrigerant demanded for a refrigeration circuit.
A refrigeration apparatus 30 includes the refrigeration circuit 34 which is constituted by interconnecting a compressor CM, a capacitor CD, an expansion valve EV and an evaporator EP by refrigerant piping 32 and where the combustible refrigerant is made to flow. In the refrigerant circuit 34, the volume per circuit is set to 2,200×10-6m3 or less, and the volume of the capacitor CD is set to 750×10-6m3 or less. As a result, the filling amount of the combustible refrigerant required for one refrigerant circuit 34 can be restrained to a predetermined value or less.
