Introduction
Non-condensable gases such as air, hydrogen, nitrogen and
hydrocarbons reduce the overall efficiency of refrigeration
systems . The effects of non-condensable gases, in a refrigeration
system, increase the system operating pressures . These in turn
negatively affect system performance . Increased compressor
discharge temperature, higher energy costs, reduced system
efficiency, leaks due to higher pressures, and increased wear on
mechanical components are all negative consequences of non-
condensable gases in refrigeration systems .
The build-up of non-condensable gases in the system can be
attributed to several factors . These include inadequate system
evacuation during service of system equipment, additions of
refrigerant, leaks through external seals on equipment as well as
refrigerant, and oil decomposition .
Common indicators of non-condensable gases in the system
are excessively high condensing pressure or temperature and
deviations in the pressure and temperature relationship at
saturation conditions . This can be determined by checking the
temperature and pressure relationship at a known point in the
system where the refrigerant is saturated, such as the condenser
drain legs or high pressure receiver, as illustrated in Figure 1 .
