Type of article: Article

Summary

The authors consider various systems: 1) conventional system without ice accumulation; 2) conventional ice accumulation, with a temperature difference of 5 deg C on ice water distribution (difference between inlet and outlet); 3) "low temperature" ice accumulation, with a temperature difference of 10 deg C on ice water distribution, and a night temperature of -7.5 deg C on primary circuit (instead of -5 deg C in the case of conventional ice accumulation). They compare the main elements of the plant in those various cases: refrigerating plant (power, COP), accumulation tanks (energy consumption, energy balance), heat exchangers, pumps, control valves, ice water distribution, air-conditioning systems (water-air and all-air). The results are summarized in a table and an economic analysis of each system type is given. J.G.
