<P>PROBLEM TO BE SOLVED: To enable a flammable refrigerant to be used within in a regulated refrigerant amount range in a refrigerating air conditioning apparatus. <P>SOLUTION: The refrigerating air conditioning apparatus 1000 exchanges heat between a heat source side refrigerant cycle 500 and a usage side transferring medium cycle 505 by an auxiliary heat exchanger 504, and a compressor 300 of the heat source side refrigerant cycle 500 is an in-container low pressure type hermetic compressor 300a, and the heat source side refrigerant 503 uses the flammable refrigerant, and the total amount of the refrigerant is reduced so that the construction can be achieved in the regulated refrigerant amount range. <P>COPYRIGHT: (C)2013,JPO&INPIT |
