23' Sceptre Air Conditioner (Cheap!)

[77SceptreOB]

The remainder of 3 medium sizes blocks of ice (12 lbs each ~ 2 gallons*) after 6 hours of cooling. Two blocks can sit on the elevated Teak ice tray. The tray was made to house crushed/bag ice but can work for the Block ice too. Basically the more ice the better! In "supercharged" mode I used 2 blocks and 20 pounds of bag ice to achieve the lowest air flow temp of -33 degrees lower than ambient cabin temp.

* the 12lb Block Ice was home made using a new plastic bathroom trash can as the form and freezing it in my garage chest freezer.
