CONDITIONING
Interpretation of the measurements.
«m»: High pressure. «s»: Over-heating (SC).
«n»: High temperature. «t»: Ambient air temperature.
«p»: Under-cooling (SR). «u»: Blown air temperature.
«q»: Low pressure. «v»: Humidity.
«r»: Low temperature. «w»: Temperature T3.
Over-heating (SC).
The over-heating represents the difference between the aircon fluid temperature at the evaporator outlet and the
evaporation temperature.
The over-heating gives the quantity of aircon fluid (in the liquid state) in the air conditioning circuit
Values for over-heating (SC).
