[ausev] !12-Volt Ice cooling with a Icester by Swampy.

Wed Aug 23 21:40:50 GMT 2006

An idea I was researching but have not gone far with is using an electronic multivibrator running off the main pack to supply 120VAC (or a close approximation) and driving a conventional window unit compressor tied to the donor vehicle condensor/evaporator systems. It would not be as efficient as the variable orifice direct drive system the Prious uses but for a low buck alternative that is better matched to the backyard EV 96-144 VDC systems it sounds feasible. 

Picture it as a typical 12VDC - 110VAC inverter without needing the step-up. 

A second idea was running an auxillary pulley off the main motor and keeping the existing vehicle compressor. Since most conversions are retaining the existing manual transmission, you have the option of setting up an "idle" setting for use when the vehicle is stationary or just put up with only having AC when moving..

>> You need (basically):
>> Ice chest
>> Smallest 12V bilge pump from Wal Mart
>> Some 1/2" through-wall barb connectors
>> 1/2" water hose

>> Large and small pieces of ice
>> About 3" of water in the bottom of the ice chest
