Abstract: A portable air conditioning unit for cars, campers, vans, tents and other enclosures. The unit is substantially noiseless and free from vibration. It comprises an insulated housing, internal cooling heat exchanger, a blower fan, and inlet and outlet ports. The coolant used is natural ice to which anti-freeze or salt may be added to increase cooling capacity. The air conditioner can cool for as long as 4 days on one change of coolant and has a very low drain on the battery supply, which may be conserved by electronic power control.

A pool leg may also be provided with a flattened end to drain water closely to the pool floor. After filling the fill cap is closed and siphoning commences upon the removal of the closure caps.
