Embodiment Construction

[0046] Hereinafter, details of embodiments of the present disclosure will be described with reference to the drawings.

[0047] [Overall structure of the ice making system]

[0048] figure 1 It is a schematic configuration diagram of ice making system 50 according to the embodiment of the present disclosure.

[0049] The ice making system 50 of the present embodiment uses seawater stored in the seawater container 8 as a raw material to continuously generate ice slurry by the ice making machines 1U and 1L, and stores the generated ice slurry in the seawater container 8 .

[0050] Ice makers (hereinafter, also referred to as "ice generators") 1U and 1L of the present embodiment are composed of, for example, a double-pipe ice maker.

[0051] In the present embodiment, the reference sign "1" is used to collectively refer to a plurality of (two in the illustration) ice makers (ice generators), and the reference sign "1U" is used to distinguish them. " and "1L". The same applies...

Abstract

This invention relates to an ice making system (50) provided with a refrigerant circuit (60) which runs a vapor compression refrigeration cycle, a circulation circuit (70) of a solution which is to becooled by the refrigerant circuit (60), and a control device (80) which controls the evaporation temperature of the refrigerant in the refrigerant circuit (60). The circulating circuit (70) includesa solution flow path (12A) of an ice generator 1, a solution tank (8) for storing the solution, and a pump (9) for feeding the solution into the solution flow path (12A). The refrigerant circuit (60)includes an evaporator (20) of the ice generator 1, a compressor (2), a condenser (3), and an expansion valve (5). The control device (80) has a control unit (81), and the higher the solute concentration of the solvent, the lower the control unit (81) reduces the evaporation temperature of the evaporator (20).

Description

technical field [0001] The present disclosure relates to an ice making system suitable for making ice slurry and a method for controlling the evaporation temperature of the ice making system. Background technique [0002] In the ice making system that generates ice slurry, if the evaporating temperature of the refrigerant is excessively lowered during the ice making operation, the amount of ice produced becomes too large, and the inside of the ice maker freezes, which may cause damage to the equipment. Therefore, it is important not to lower the evaporation temperature of the refrigerant too much during the ice making operation. [0003] Patent Document 1 discloses an evaporating pressure control device for an ice maker capable of continuous ice making for a long period of time without performing a defrosting operation by preventing ice clogging of the ice maker. [0004] In the evaporation pressure control device of Patent Document 1, the refrigerant evaporation temperatur...
