COMPRESSOR PLANT OF TRANSPORT REFRIGERATOR Russian patent published in 1997 - IPC

FIELD: refrigerating engineering; transportation and storage of perishables. SUBSTANCE: compressor plant includes isothermal body, compressor driven by engine of truck, piping system, shut-off adjusting fittings, atomizers, vortex tube which is connected in series with storage batteries and inner volume of truck body provided with perforated envelope mounted at spaced relation to body. To create oxygen-free atmosphere in refrigerated truck body, gas medium separator is provided which is connected in parallel with vortex tube. When engine is operating, compressor delivers compressed air to vortex tube inlet where it is divided into hot and cold air which is then delivered to storage batteries and inner volume of truck, cooling or heating it as required. Air is bled-off to compressor inlet. EFFECT: intensification of cooling process; reduced losses of products; smooth temperature field. 4 cl, 1 dwg
