COMPRESSION REFRIGERATING PLANT Russian patent published in 1995 - IPC

FIELD: refrigerating engineering. SUBSTANCE: compression refrigerating plant has housing 1 with inlet and outlet ports for atmospheric air, and heat exchanger 5, fan 6 located inside the housing in the line of atmospheric air, and compressor 8 installed in soundproofing enclosure 7. Compressor inlet connection 9 is connected to the atmospheric air line, and outlet connection 10 is connected to to heat exchanger 5 through receiver 11 positioned between them. The heat exchanger is connected to the cold air consumer through moisture separator 12. To reduce the sound level and intensification of compressed air cooling, two horizontal partitions 13 and 14 are additionally installed in the upper part of the housing. Upper partition 13 together with one of the housing walls forms air gap 15 in the atmospheric air line, and lower partition 14 has central port 16 in the same line, in which fan 6 is located. Cooled coil 17 and receiver 11 secured in partition 14 against air gap 15 are additionally installed between the compressor and heat exchanger. Installed past heat exchanger 5 is moisture separator 12 secured in the same partition 14 against the same gap 15. Filter 18 is additionally positioned in inlet port 2, and the coil is installed in the atmospheric air line between fan 6 and compressor 8. Additionally installed at inlet 19 in sound-proofing enclosure 7 is air reservoir 20 with fine filter 21 at the inlet, connected to inlet connection 9 of the compressor through bellows 22, and enclosure 7 proper is installed on shock-absorbers 23. EFFECT: improved design. 1 dwg
