HOLD-OVER SYSTEMS WITH BINARY ICE UTILIZATION

This paper reviews different types of cold accumulation systems. The utilization of such systems due to the need of compensation of peak cooling loads by air conditioning of the large buildings or the technology requirements is considered. According to the type of storage media and the way a storage medium is used water (the aqueous solution) and ice. When using standard systems of cold accumulation to the consumer single phase coolant is served. System with binary ice can bring to the consumer a two-phase coolant. Application of two-phase coolant when cooling improves energy and performance characteristics of the refrigeration system with accumulation of cold. It justifies the reasons for using binary ice as a coolant. Examples of large industrial facilities using cold accumulation with binary ice are given.
