Приведено технико-экономическое обоснование использования гравитационного накопителя для филиала «Гомельский комбинат хлебопродуктов». A feasibility study is presented for the use of a gravitational storage device for the Gomel Bread Products Plant branch. Methods of intensification of heat exchange by modification of a two-phase thermosiphon are considered. The design of a periodical thermosiphon with an organized circulation of the coolant has been developed and patented. An experimental installation has been created to study the efficiency of closed two-phase heat transfer devices. The process of temperature exchange in closed heat-transmitting devices filled with distilled water, ethyl alcohol and ozone-safe refrigerants was experimentally investigated.
