Cold Accumulators as a Way to Increase Lifetime and Cryosystem Temperature Range

An approach for reducing the air conditioning costs in office buildings in Vietnam

“…According to the research of D. Shlichkov [2], a chilling system with a storage tank, in which the ice freezes on the outer surface of the heat exchange tubes of the evaporator, leads to a significant reduction in electricity costs for air conditioning systems. The combined method between cold accumulators and cryocoolers has been considered by Arkhipov et al [3] in order to increase the life of the cryogenic cooling system. According to R. Sekret et al [4], the cold accumulator is applied by using the latent heat of a phase-change material in a layer of capsules with diameters of 80 mm, 70 mm, and 60 mm, the optimal working conditions according to the study are when using capsules with a diameter of 70 mm and a mass flow rate of 0.084 kg/s.…”
