Thermacool is the name for the air conditioning system developed at the request of aircraft owners who have always wanted an electric air conditioning system capable of being run on the ground with a GPU and, at low RPM. Until now such systems were only available for twin engine aircraft with 28 VDC and 100 amp alternators. With the development of Thermacool came the ability to run all electric air conditioning systems on less power.

Air conditioning for general aviation aircraft use automobile compressors to move the refrigerant through the system. Some compressors are belt driven off the engine, some are hydraulically driven and some driven with electric motors and belts. The later has always been a favorite so the aircraft could be cooled on the ground. However the single engine market was exempt from this type of system due to the high electric loads and weight.

Thermacool air conditioning has addressed many of the mentioned problems and is introducing an aircraft system that will make it possible for most general aviation aircraft to fly with electric powered AC.

The heart of the system is Kelly Aerospace's compressor, and brushless DC powered technology. The new compressor is a hermetically sealed unit utilizing a rotary pump design, driven by a brushless DC motor. The compressor weighs only 14 pounds and runs on 24VDC or 48VDC. The total system draws only 50 amps.

Working with this design, the system is virtually maintenance free. Location of the Thermacool compressor can be accomplished just about anywhere in the aircraft. Small in size, the compressor can optimize space requirement and not jeopardize performance. Lighter weight connective components and brushless DC fan motors are also used because of the higher efficiency and judicial use of power. Cooling comfort can be enjoyed even before the engine starts.
