Title:
ICE MAKING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/138780
Kind Code:
A1
Abstract:
An ice making system is provided with: a refrigerant circuit which executes a vapor compression type refrigeration cycle and which includes a compressor (2), a condenser (3) for condensing a refrigerant discharged from the compressor (2), a first expansion valve (5) having an adjustable degree of opening, for reducing the pressure of the refrigerant from the condenser (3), a flooded evaporator (1A) which causes the refrigerant of which the pressure has been reduced by the first expansion valve (5) to evaporate, and a superheater (6) which imparts a degree of superheat to the refrigerant expelled from the flooded evaporator (1A); a recirculating circuit for causing a cooled medium cooled by the flooded evaporator (1A) to be recirculated; and a control device (50) which controls the degree of opening of the first expansion valve (5) in such a way that the superheater (6) imparts to the refrigerant a degree of superheat (SH) which enables a dryness (x) of the refrigerant expelled from the flooded evaporator (1A) to be kept within a prescribed range less than 1.
