FIELD: machine building. ^ SUBSTANCE: proposed air refrigerator comprises turbo compressor, turbo expander and combustion chamber. Turbo compressor outlet communicates, via first air cooler, with turbo expander compressor inlet. Turbo compressor turbine inlet communicates with combustion chamber outlet. Turbo expander compressor outlet communicates, via second air cooler, with the inlet of turbo expander turbine, while outlet of the latter communicates with cold consumer. Turbo compressor outlet communicates with the inlet of air control valve that serves to divide the flow into two flows. Second outlet of air control valve communicates, via first air cooler, with turbo expander compressor inlet. Combustion chamber communicates with fuel feed assembly, air control valve first outlet and steam source outlet. Combustion chamber outlet communicates with turbo compressor turbine inlet. Turbo compressor turbine inlet accommodates steam source. Turbo compressor and turbo expander incorporate air-lubed bearings. ^ EFFECT: increased refrigeration factor. ^ 4 cl, 1 dwg |
