A METHOD AND SYSTEM FOR CONTROLLING THE INITIATION OF A FREEZE CYCLE PRE-SET TIME IN AN ICE MAKER

Abstract

A novel control logic for an individual cube spray type ice machine. The duration of thc freeze cycle is able to adapt to changes in inlet water temperature, changes in ambient air temperature, and the impact of warm temperatures of internal ice making parts within thc ice machine due to off cycle periods. This is accomplished through a combination of starting a freeze time period only after the water temperature for the volume of watcr circulating over the evaporator has reached approximately 32'F, and a freeze time pcriod value that is a function of the refrigerant temperature leaving the condenser at thc timc where the water reaches approximately 32°F.
