• Refrigerant (R134a) is compressed to approximately 15.0 kg/cm
compressor.
• The compressed refrigerant flows into the condenser at high temperature (approximately 80°C
(176°F)).
• The refrigerant in the condenser is cooled to approximately 60° by the condenser fan. At this
time the refrigerant changes from the gas to the liquid state, even though the temperature has
only been reduced 20°C (68°F). (From 80° - 60°C (176° - 140°F)).
• The refrigerant in its liquid form is injected into the evaporator through the expansion valve. At
this time the pressure is reduced by approximately 2.0 kg/cm
also reduced. As a result, the refrigerant absorbs the heat from the air surrounding the
evaporator creating a cooling effect and changes from the gas to the liquid state.
• The refrigerant once again flows into the compressor in the gaseous state and the process is
repeated.
Refrigerant gas is pressurized and sealed in the air conditioning system. Special
precautions are required for the proper recharging or release of refrigerant. Release of
refrigerant into the atmosphere is strictly regulated by law. Make sure that you are in
compliance with all mandated federal, state and municipality requirements, before starting
any service or repair of the air conditioner. Refrigerant gas used in the system must meet or
exceed specifications for R134a refrigerant, or any subsequently issued environmentally-
mandated standard.
