«n»:High temperature.«t»:Ambient air temperature.
«p»:Under-cooling (SR).«u»:Blown air temperature.

Under-cooling.
The under-cooling represents the difference between the condensation temperature and the aircon
fluid temperature at the aircon condenser outlet.
The under-cooling gives the quantity of aircon fluid
(in the liquid state)in the air conditioning circuit.
