| description | Unique elements of the working processes of a low-speed piston compressor, not typical for high-speed
piston machines, are considered. It has been experimentally proven that under operating modes with an
elevated gas temperature at the inlet of a low-speed compressor (above the temperature of the cooling
medium), a noticeable decrease in the gas temperature is observed during the suction process. That is,
the first part of the cycle in the stage, the gas is cooled, and the beginning of the compression process
will occur at a lower temperature than the gas temperature at the standard suction point. In addition, the
assumption that when a low-speed compressor operates on refrigerants, operating modes in the wet steam
region are possible, in which condensation of the working fluid is observed at the end of the compression
process, has been experimentally confirmed. Such operating modes can be used in compact low-capacity
refrigeration machines with a decrease in the weight and size parameters of the condenser unit. The conducted studies have shown the need to verify the calculation methodology for the types of
piston compressors considered in the article and to refine the latter taking into account the features of the
working processes of low-speed piston machines. |
