Abstract

A novel control logic for an individual cube spray type ice machine. The duration of the 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 the 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 water circulating over the evaporator has reached approximately 00C (32'F), and a freeze time period value that is a function of the refrigerant temperature leaving the condenser at the time where the water reaches approximately 00C (32'F). 530 Start Freeze Sequence 502 Monitor Water Sump Temperature within 504 Yes Measure Refrigerant 506 Temp Leaving Condenser Determine Remaining Freeze 508 Time from Stored Table of Time vs. Refrigerant Temp 510 Start Freeze Countdown Timer Monitor Freeze T imer Value No 514 Timer Value = 0? Yes 516- Start Harvest Sequence
