Title:
AIR CYCLE REFRIGERATION AND COOLING SYSTEM, AND TURBINE UNIT FOR THE AIR CYCLE REFRIGERATION AND COOLING
Document Type and Number:
WIPO Patent Application WO/2007/023835
Kind Code:
A1
Abstract:
An air cycle refrigeration and cooling system for sequentially performing compression
by a precompression means (2), cooling by a heat exchanger (3), compression by
a compressor (6) of a turbine unit (5), cooling by other heat exchangers (8, 9),
and adiabatic expansion by an expansion turbine (7) of the turbine unit (5). The
turbine unit (5) has a compressor wheel (6a) and a turbine wheel (7a) that are installed
on a common main shaft (13) and drives the compressor wheel (6a) by power generated
at the turbine wheel (7a). The main shaft (13) is rotatably supported by rolling
bearings (15, 16), and thrust force applied to the main shaft (13) is received
by an elerctromagnet (17). A pressure uniformizing means (81) for uniformizing
gas pressure at both ends of the rolling bearings (15, 16) is provided.
