This video depicts my window-mounted air conditioner, Soleus Air Window Mounted, 5,000 BTU air conditioner, mounted inside of my 1989 Ford Econoline Van, E150 Club Wagon van. Air conditioner does not stick out of the windows, or does it protrude out of the van. Air conditioner operates in an enclosed space, and built discreetly inside of the van. Air conditioner is built in the rear area of the van, into a partitioner wall made of plywood. A duct ventilation system is built to assist in efficient air conditioner operation. 8 Inch duct captures the expelling air from the air conditioner, and expels through a 6 inch whole that was cut at the bottom of the van. This creates a stealth-approach to mounting a Window-Mounted air conditioner inside of such enclosed space. A 750 Cubic foot per minute rated duct fan assists in air conditioner exhaust/expelled air through the bottom of the van. Air conditioner is powered by three solar panels, 325 Watts each (975 Watts total). A 2,000 watt, pure sign wave inverter powers system.
