Lubricants for HFC Refrigerant Compressors.

Status Report on Polyalkylene Glycol Lubricants For Use With HFC-134A In Refrigeration Compressors

The objective of this work is to assess the sensibility of a computer simulation program, employed to analyse the transient behaviour of· domestic refrigerators, to the adopted capillary tube and condenser mathematical modelling approach. Although all the comparisons, presented in this work, are related to a specific computer program, it is believed that, at least in a qualitative way, they are...

Refrigerant Dependent Optimum Clearance For Rotary Compressors

The clearance between the cylinder wall and the rotating piston is critical to the efficiency of a rotary compressor. A large clearance causes internal gas leaks and capacity and efficiency losses. A tight tolerance increases the manufacturing cost. For a given clearance between the cylinder and the rolling piston one can determine a radial and angular offset of the cylinder with respect to the...
