<p><P>PROBLEM TO BE SOLVED: To provide an air conditioning system with a plurality of working units, suppressing a cost increase of parts constituting a refrigerant circuit when the refrigerant circuit has high maximum working pressure. <P>SOLUTION: The air conditioning system 1 comprises the plurality of working units 5, the vapor compression type refrigerant circuit 10, and an accumulator 25. The refrigerant circuit 10 has a high pressure part 10a formed with a component connected thereto in which high pressure refrigerant having a maximum working pressure of 3.3 MPa or higher can flow and a low pressure part 10b formed with a component connected thereto in which only low pressure refrigerant having a maximum working pressure of less than 3.3 MPa can flow. The accumulator 25 is one of the components forming the low pressure part 10b, which can reserve the refrigerant circulating in the refrigerant circuit 10, as liquid refrigerant. The refrigerant flowing in the low pressure part 10b and the high pressure part 10a is R410A. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
