This article examines the areas of use of water with near-zero temperature. It proposes a vacuum water-cooling technology where water acts simultaneously as a coolant and a cold carrier. In order to reduce the temperature differential in the water layers during vacuuming, a composite is created from alternating layers of ice and water, where the upper water layers remain free from ice. Such a method helps reduce energy consumption for implementation of the process. The cited experimental data on the temperature field across the evaporation vessel depth suggest uniformity of the field with a near-zero temperature index. Besides the possibility of getting near-zero temperature in the alternating water and ice layers, there occurs a significant rise in the cooling capacity of such a composite, which produces a salutary effect on the economic factors of the unit.
