Abstract: New Peltier semiconductor heat transfer systems are presented herein. In particular, Peltier heat transfer systems of Peltier semiconductor elements of highly unique shapes are arranged to bias the cooling side with respect to its size and consequently performance. In effect, a Peltier heat transfer system is created whereby the Peltier called side is greatly reduced in size and the Peltier hot side is greatly expanded in size.

The entire cooling fact of the Peltier device is brought to the small space approximated by a point. Thus a ‘point’ heat source such as a semiconductor laser are high-performance light emitting diode is more effectively cooled by these systems.

Abstract: The present disclosure adjusts an air conditioner (A/C) compressor load responsive to the available torque to provide a compromise between A/C system and vehicle performance. The maximum available torque is monitored in real-time, and it is determined if there is enough torque to keep the A/C on for a fixed displacement compressor or how much the compressor displacement can be destroked through a current control for a variable displacement compressor.

Accordingly, this broadcast enables a determination of whether there is enough torque available to maintain the A/C system in a controlled manner. Advantageously, the present disclosure avoids an abrupt turn-off or turn-on of the A/C system. Rather, the present disclosure maintains the A/C system in a controlled manner providing improved vehicle driveability.
