Title:
REFRIGERATION DEVICE
Document Type and Number:
Japanese Patent JP2014129942
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a refrigeration device in which a refrigeration circuit is filled with changed refrigerant of an appropriate filling amount in a case of the type of the refrigerant of the refrigeration device changes.SOLUTION: A refrigeration device 10 performs a vapor compression refrigeration cycle by circulating refrigerant R32 of a first filling amount in a refrigeration circuit 20 that includes a compressor 31, an outdoor heat exchanger 33, and an indoor heat exchanger 41. The refrigeration circuit 20 is configured to be filled with refrigerant R410A of a second filling amount if the refrigeration circuit 20 operates while the refrigerant R410A different from the refrigerant R32 circulates in the refrigeration circuit 20. In this case, the first filling amount of the refrigerant R32 filled into the refrigeration circuit 10 is adjusted to a converted amount converted from the second filling amount on the basis of a density ratio of the refrigerant R32 to the refrigerant R410A.
