Title:
HEAT SOURCE MACHINE AND OPERATIONAL METHOD THEREOF
Document Type and Number:
Japanese Patent JP2017141372
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a heat source machine capable of keeping environmental load low and outputting high temperature hot heat, and an operational method thereof.SOLUTION: A heat source machine 1 is provided that has a centrifugal compressor 2 for compressing a coolant, condensers 3 and 4 for condensing the compressed coolant, expansion valves 5 and 11 for expanding the condensed coolant and a vaporizer 7 for vaporizing the expanded coolant. The coolant encapsulated in a coolant circulation circuit 8 constituted by sequentially connecting the centrifugal compressor 2, the condensers 3 and 4, the expansion valves 5 and 11 and the vaporizer 7 contains a composition A, a composition B and a composition C, the composition A has 4 or 5 carbon atoms, 6 or more fluorine atoms and one or more oxygen atom, the composition B has 4 or 5 carbon atoms and 6 or more fluorine atoms, the composition C has 3 carbon atoms, 2 chlorine atoms, 3 fluorine atoms and an intramolecular double bond, the composition A, the composition B or the composition C have a boiling point of 20°C or more and a critical temperature of 180°C or more.SELECTED DRAWING: Figure 1
