Thread: Heat build up in cabin

Hi All

Wasn't there some work done a few years back about using the exhaust heat as a energy source for airconditioning ?
Silent Knight fridges worked that way, both electric and the kerosene types.
They were simple tough old fridges that took up a heap of room in the kitchen, when they played up, the fix was to bowl them around the backyard, they worked well after that.

Cheers Arthur

I have had a look under today, and have a few ideas about redirecting some of the airflow from the radiator and exhaust air, which travels back at highway speeds creating a low pressure area under the seat box etc, drawing a kind of vortices which just 'whirlpools' the hot air. At least that is my theory so i'm going to try and redirect the air rather than try and prevent the transfer through the seatbox and insulation, which is only effective if you are doing short runs. After 30 minutes or more of high speed driving, the heat will travel through into the cab anyway as it will conduct itself, albeit slowly, through the layers of metal and rubber matting. My feeling is to try and reduce the heat in these areas, rather than manage it after it has already appeared.

Well I'd subscribe to that theory.

I was thinking along those lines yesterday as mine also gets very hot and just in the centre section between the boxes under the seats.

There is a "pocket" of space above the transfer case that appears as though it could be a good place for an eddy of air to sit. Some aerodynamic disturbance via a scoop might do the trick.

Watching with interest

I had a chat to our A/C fellows today about the 110's system, he reckons I should be fitting a second evaporator in the rear and run a twin system due to alll the windows etc. I have a small rear evaporator from a HJ61 Sahara that will fit nicely in the rear corner...

JC I was just kidding

The A/C units from the rear of the D2 would also be excellent as they are pretty well stand alone. Problem is they are quite scarce.

My 08 svx heats up the underseat boxes very well ( i might put a raw chook and some veggies in the battery box), on a hot day the footwell gets nice and toastie.......i don't notice it because usually my head is melting because of the oh soooo cool glass sunroof inches above my nut......ye great idea , black defender with a glass sunroof and they gave me heated seats.....somebody in India has a sick sense of humour

I have a 08 130 mine also heats up around the handbrake area
spoke to the dealer when it went in for a service they know about
the problem and said so do Landrover but will not do anything about

On the 08 defender it's not the gearbox getting especially hot under strain is it ?

Thanks for the advice. I actually did do something about it (original was posted in 08) finally - it starts here

Solve the heat and noise problem in one go install the noise killer noise insulation kit and it does a pretty good job of reducing the heat. Can now put bare feet on the floor. Does a superb job of reducing noise as well.

yep ,,i got it ..............5 day plod thru high country few weeks back,saw me with a permanent left calf ,,cooked medium to well done ,,i kid you not.
