The aim of this article is to identify opportunities of energy saving during the production of cold. Analysis of the cold
accumulation in refrigeration units with variable refrigeration load was carried out in order to reduce energy consumption.
Schemes of ice-water and air conditioning installations, which use ice accumulators, are presented. Varieties of ice
accumulator cycles and calculation results are provided. Reduced cooling efficiency of the two-stage versus single-stage
cooling is confirmed. The possibility of replacing ice accumulator with seasonal cold accumulator is considered. A onedimensional
mathematical model of ice buildup in ice accumulator is offered. The calculation results are compared with
the characteristics of actual products. Energy saving by replacing ice accumulators with seasonal cold accumulators is
confirmed by the results of calculations.
