Экспериментальное исследование работы термосифонов, заправленных хладагентами R404A, R407C, R410A

Abstract

Currently, thermosyphons are rarely used in industry. This phenomenon can be explained by the fact that the physics of the processes occurring in thermosyphons (jointly occurring processes of heat conduction, convection and phase transitions in the zones of evaporation and condensation) has not yet been sufficiently studied. In addition, the accumulated knowledge in this area is, as a rule, the conclusions obtained for specific versions of thermosyphons and coolants, design schemes and technical solutions. Analysis of the most significant results of studies of heat transfer in closed two-phase thermosyphons shows that the most significant characteristic of their work is thermal resistance.The established experimental data will further allow the development of efficient heat exchangers with two-phase heat transfer elements for their use in power engineering, refrigeration engineering, ventilation and air conditioning systems, and industry, in order to reduce energy consumption, material consumption, and improve the quality of products.
