Robinson Helicopter now offers air conditioning in the R44 Raven II. It is a simple, lightweight system designed to reduce humidity and provide airconditioned comfort throughout the cabin.
Each seat is equipped with individual overhead vents providing 250 CFM total airflow. The 33 lb system uses the latest automotive refrigerant and has 12,000 BTU/hr cooling capacity. The evaporator and fan are mounted to the aft cabin bulkhead, preserving all four baggage compartments.
During operation the system uses approximately three horsepower and is controlled by a toggle switch with off, low, and high fan settings. The compressor is engaged when the fan is switched on and automatically disengages when the engine is near full throttle to ensure maximum aircraft performance.
RHC has spent two years on the design, working to maximize its efficiency and reduce its weight. While the system is considered light at 33 lbs, the added weight is still a factor that should be considered. The goal is to provide relief in areas where the climate is very hot and the use of the helicopter would be seriously limited without air conditioning.
The system is priced at US $18,000 and will be sold as optional equipment in the R44 Raven II only. It is not yet an option for the Clipper II and is not available for retrofit. Deliveries of new air conditioned ships will begin in 2006.
