Description

[Brief explanation of the drawing]

FIG. 1 is a power consumption characteristic diagram showing the relationship between steam temperature, condensation temperature, and power consumption. FIG. 2 is a sectional view of the plate ice maker. FIG. 3 is a diagram showing a cooling system and a condensing system. FIG. 4 is a control circuit diagram. FIG. 5 is a condensing pressure characteristic diagram showing changes in condensing pressure as the ice making and ice removal cycles progress. In the figure, 1 is a cooler, 2 is a compressor, 3 is a condenser, 6 is an automatic ice-making valve, 7 is a solenoid valve, 12 is an ice-making timer, and 15 is a first
16 is a second switch.

Claims (1)

[Scope of utility model registration request] A refrigerant compressor, a refrigerant pipe of a water-cooled condenser for condensing refrigerant from the compressor, an expansion valve, and a cooler are connected in an annular manner, and a hot gas is connected in parallel to the condenser and the expansion valve. An ice maker comprising a cooling system of the ice maker equipped with a valve, and a condensing system equipped with a cooling water pipe of the water-cooled condenser and an automatic water control valve that automatically controls the amount of cooling water passing through the cooling water pipe. In this case, a solenoid valve is installed in parallel with the automatic water control valve to lower the condensing temperature and condensing pressure from the early stage of the ice-making cycle until the temperature or pressure of the cooler drops to a predetermined value, and thereafter until the end of the ice-making cycle. An ice maker comprising a control circuit that senses the temperature or pressure of the cooler and controls opening and closing of the solenoid valve so as to increase the condensing temperature and pressure.
