power overnight stnadby while in motion? (van)

[knighty]

bit of an odd one

freezer van... (Mercedes sprinter)

can the overnight (240v) standby be powered up while the van is in motion to provide cooling (without engine compressor - no space for one, already has aircon and extra alternator) ?

or will the bumps/vibration kill the 240v compressor?

electric 12v systems are priced really high

could buy a 12v compressor, but might as well use the mains one when it's there

Sure, with very long cables...

Some trailer units have a three phase vertical scroll compressor they run on road and standby (Carrier Vector), not sure if there a special model or just an ordinary comp though.

Are 12VDC to 240VAC invertors not an option here? a couple of decent batteries and a couple of extra alternators should keep a big ole invertor going

may not be the most efficient solution

if you have any doubts about the ability of the compressors ability to cope with travel while running the additional vibration compensation shouldn.t be difficult to achieve

[knighty]

an extra battery and an inverter are exactly what I'm thinking

a lot of shop delivery vans around here use electric systems... but they have a 12v motor belt driving a standard engine mount compressor... seams a bit noisy to me

not sure if it's the same in the rest of the world?

EDIT: just googled it to check... the supermarkets use a "Carrier Neos 100" system...
1.2kw of cooling at 0'C and 470watts of cooling at -20'C (no idea on ambient temp for those)


electric motor is 1420watts.... so 118amps at 12v :-o
