Need some help you L29 guru's Especially from Bill
Looking at a concept to get Freon air in the L29 cockpit. Now , I need to
see what I have left for generator amperage after running all necessary
components. We know gen is 100 amp 28 volt permissible 30 amps for 30
min per manual
In theory the electric compressor will not cycle on until after engine
start. So, 100 amp gen. What's available for the new a/c
Lets discuss what's running.
1. Invertors for attitude indicator_____ amps
2. low pressure fuel pump electric_____ amps
3. day switch lights etc______ amps
4. igniters cycle off
5. avionics ________amps depends on aircraft but an average say
6. I need about 50 to 60 amps max in cruise . Do we have it??

Get a 24V samarium cobalt motor (Like they use on scooters) and connect it to a Sanden 505 compressor, then buy an aftermarket condensing unit. Startup current draw is about 70 amps, will then settel to about 40 amps. You still need to get rid of condensation. I've been working this problem on and off for several years. This is the best bet. Another idea was to buy these teeny little window units that they sell in SAMs club for about $80. Seperate the condensing unit from the evaporator and then use a 24V 2500 watt inverter.

Bob,
If you want A/C buy a L-39! Works great, lasts long time!
