12v Air conditioner - Viesa

Barriesimpson said:
Well I have decided against the Viesa and have gone for the Bergstrom OpenAir which is the latest invention it seems. Runs on 12V and has some very good reviews out there. €1.850 fitted - only €100 more than the Viesa and it is a proper air conditioner.

At least its a proper condensing Air con unit rather than a "swamp" cooler evaporative, so should work better`

This is what I am expecting, the reviews out there are promising. I will post my thoughts once I have the van and tested it. Should be soon - in time for the summer heat waves......
 
Ok, as you all know we finally picked up the van and are now travelling around the islands before going up through Europe. Today we have 31C outside, so a perfect opportunity to test the Bergstrom air conditioner. I just switched it on, have all the windows and doors closed and am waiting to see how it does.

Don't keep us in suspense :giggle:
 
I strongly suspect that this is an evaporating air cooler and not an "airconditioner" with a compressor (and refridgerant)...

Couldn't find the power consumption on the Web page I looked at.

I do so hope it cools you satisfactorily.

It says it has a compressor and runs at up to 2kw. It sounds like a proper heat exchanger AC to me.

No JJ, it's a fully fledged air conditioner with compressor and refrigerant. Runs on 12V and works great, in one hour I had the temperature down to 26C while being 31C outside. I'm happy with that.

Ok, sorry for the wait, it works very well. Dropped the temperature from 31 to 26 in one hour and all on 12V. Battery consumption was minimal as the solar panel (235W) kept everything under control. At the end, when I switched it off, I still had 82% battery power (2x 95ah). So I am very happy with the purchase and can recommend this kit to anyone.
 
Today we are at 32C outside so I switched on the air conditioning again. In one hour the temperature inside the van has dropped to 25C and battery power is at 87%. The sun is blazing out there so am expecting a full battery recover before the sun sets. Happy days 😁

one more solar panel maybe and you can forget the % of battery on a decent day

thanks for taking the time to test/review it
 
Would you mind telling me the model number of the Unit Barriesimpson ?

2.795 sterling seems an awful lot of money. I paid 1.850 Euros, fitted, for the Bergstrom (I ordered it at the time of buying, so probably no labour charge).

Bloody hell, bit over the top I would say.
 
Today we are plugged in for the first time. So no battery worries and after lunch I switched on the air conditioning to auto 16c. It's been on for about 2 hours now and I'm thinking I may have gone over the top. I no longer need to keep the beer in the fridge.....

Yes, will do. I hope to have the van in my possession at the end of the month - there is a waiting list in the workshop for the installation of the air, plus the solar panel and the inverter. You are in Spain, me too, the Canaries.

How have you got on with the Bergstrom aircon. I'm looking at 12v aircon and it would be helpful to get an actual point of view.

During July and August, in the Canary Islands (35ºC or more), it worked perfectly. There is a caveat, due to only having 2x 95ah agm batteries, I could only run it for around 2 hours max 3 before having to turn it off if not plugged into EHU. But this was mostly quite enough time to cool down the van to around 25ºC, a drop of 10º. Running it all night would not be possible with my current set up, but next year I will change the batteries for lithium and hope to get better performance. There are settings for lead/acid or lithium batteries on first setup. If you need to change the settings the apparatus needs to be completely disconnected from the power supply, same if you change the power setting (1.200 or 2.000 I seem to remember are the options). I have mine on the ECO setting to preserve battery power. Since September we are in the mainland of Spain and have not needed to use it, next summer in the Canaries I will continue testing. Hope that helps.

Thanks Barry. That's very encouraging. I've got 2x150 lithium and 95 AGM and 2 95w solar panels. Sounds like that will be enough to keep us cool.

The 2x 95w solar might not be enough. I have a 235w panel in my setup now, but thinking of adding another one the same when I go lithium. Please note that my name is spelt Barrie 😀

Oops sorry Barrie. Thanks for the updates. I might be stuck with the 2x95 until the warranty expires. They seem to keep the batteries well topped up.
