Description

Cooling control, called peak shift (PS) and peak cut (PC), for a beverage vending machine is carried out to reduce the electricity consumption around noon on summer weekdays. It helps reduce the electricity demand on power generation systems. In conventional PS/PC control methods, complex algorithms are needed to control PC start temperature inside the vending machine, or the temperature depends on the driving frequency of the cooling device. In this paper, a highly practical PS/PC control algorithm is proposed for a beverage vending machine. The algorithm extends PC time and proposes an optimum PS start time. The effectiveness is confirmed by a field-test.
