INTRODUCTION
Besides emphasizing vapour compression cycle, this trainer can be used to describe all the problems due to the insertion of this cycle in the car since it has to adapt to a hostile, very hot, moving, vibrating environment that generates variable power mechanical energy.
TRAINING PROGRAM
• Plant starting and safety devices intervention checking
• Studying the operation of an automotive air conditioner
• Studying the operation of an expansion valve
• ON-OFF control: condenser fan automatic control
• Examining the system behaviour versus the variation of:
- engine r.p.m.
- air flow
