Introduction
Non-condensable gases such as air, hydrogen, nitrogen and
hydrocarbons reduce the overall eciency of refrigeration
systems. e eects of non-condensable gases, in a refrigeration
system, increase the system operating pressures. ese in turn
negatively aect system performance. Increased compressor
discharge temperature, higher energy costs, reduced system
eciency, leaks due to higher pressures, and increased wear on
mechanical components are all negative consequences of non-
condensable gases in refrigeration systems.
e build-up of non-condensable gases in the system can be
attributed to several factors. ese 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. is 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.
