Dual Zone A/C System Description

The electronic A/C system consists of the following 4 major Systems:
^ The refrigeration system
^ The heater system
^ The air distribution system
^ The mode/temperature control system

The driver may select the following functions from the system control panel:
^ The desired interior temperature (the SET temperature)
^ The fan speed
^ The mode of operation

One of these modes is a fully automatic mode in which the system determines the following conditions:
^ The appropriate air intake location
^ The appropriate air discharge location
^ The fan speed
^ The discharge air temperature according to the driver-selected temperature

The system's network of sensors also provides this information.
The Oldsmobile electronic A/C system uses a Cycling Clutch Orifice Tube (CCOT) type refrigeration system. A Variable Displacement Orifice Tube (VDOT) type refrigeration system is used with the Buick.
