Machine de réfrigération

摘要

The two stage compressor has its motor and shaft between the elongated horizontal condenser and evaporator, parallel to each other and with the former above the latter, the shaft being perpendicular to a vertical plane crossing the evaporator parallel to its longitudinal axis. The compressor 1st stage intake is connected to the evaporator via an annular channel with adjustable guide vanes. The first stage of the compressor has two collector volutes and these are connected via internal pipes to the intake port of the second stage which has a single collector volute. The cooler for the compressor motor is fed with a bleed fraction of re-evaporated condensate from an intermediate evaporator chamber to which that bleed is fed. Compact, high thermal efficiency plant.
