ICE MAKING SYSTEM AND REFRIGERANT CIRCUIT USED IN THE SAME
Document Type and Number:
Japanese Patent JP2019124382
Kind Code:
A
Abstract:
To suppress equipment costs of an ice making system.SOLUTION: An ice making system 50 includes a refrigerant circuit 60 performing a vapor compression type refrigeration cycle, and a circulation circuit 70 for a solution as a cooled object of the refrigerant circuit 60. The circulation circuit 70 includes a solution flow channel 12A of an ice generator 1, a solution tank 8 for storing the solution, and a pump 9 for pressure-feeding the solution to the solution flow channel 12A. The refrigerant circuit 60 includes a flooded evaporator 20A of the ice generator 1, a compressor 2, a condenser 3, and an expansion valve 5 of which an opening is adjustable. The refrigerant of the refrigerant circuit 60 is composed of a refrigerant which keeps a discharge superheat degree of the compressor 2 to be 10 deg or more even when it is sucked to the compressor 2 with a degree of dryness allowing oil return from the flooded evaporator 20A.SELECTED DRAWING: Figure 1
