Air con system size

[Harrja79]

I am doing a custom air con system in my defender build. I am going for an overhead evaporator and am trying to make it as small as possible but also effective. I can do a 22,000btu evaporator which is smaller or a 32,000btu which will effect head room for the rear passengers. Just seeing if anyone has experience of a 22,000btu size system with 390cfm blower? Would it be sufficient? I want aircon that would be effective up north. Thanks

The google search function at the bottom left of the page will help you here. I put in 'defender air conditioning' and this page (https://www.aulro.com/afvb/technical-chatter/58456-defender-air-con-cost-avalbility.html)came up as well as others . Have a look, there's plenty of fodder.
Looks like this: Search AULRO.com ONLY!
