    3 ways and ice creams

    I went up to Ophir just north of Orange for the weekend and took my Jayco campervan for its first run. When getting the camper set up I noticed the inbuild 3 way seemed to work much better than you would think reading all the reports - even on 12v mine seems to work well - in testing the freezer section was often over -20 degrees even on hot days.

    So I thought I would test it and bought 4 Weis Macadamia and Mango bars as the sacrificial ice creams ( they are in their own little sealed packets in case they melded). I ran the fridge on 24v for the 12 hours prior to leaving and the freezer was showing -20 when I put the ice creams in.

    I switched to 12v on hooking up, outside temp was 28 degrees and when I unhooked at Ophir about five hours later - I had a nice frozen Weis bar - temp on arrival was -16 but during the trip it had dropped to -10.

    The next day the van was running on gas and temp got down to -28 at night (10 outside) and -20 during the day (up to 30). Another frozen Weis for dessert that night.

    Got back home last night after about 7 hours running the fridge on 12v and ate the two remaining Weis bars.

    So contrary to a lot of comments on 3 ways - my experience has been extremely positive with - 20 being held on 30 degree days so maybe -10 on a 40 degree day when on gas. On hot days 12v would maintain freezing but maybe not for ice cream.

    I also had my ebay special (what not an Engel ) 55l compressor fridge with me in case all else failed. I put a lot of the drinks in it - my 45A/h van battery was up to running it for the weekend but was getting a bit low when I had to switch to 12v on the 3 way just before hitching up to come home - voltage was down to 11.7.

    Firstly, being pedantic, the temp had risen from -16 to -10.

    No argument, the 3 way fridges work, the main problem is that they are very subject to level. On a fridge used in a van on the highway, provided the roads are the modern flat ones not the older cambered roads the fridge will work while traveling. The Electrolux manual says when stopping for more than 20 minutes the fridge should be leveled (both ways), if the fridge is built-in this means leveling the van. A real hassel when maybe stopping for half an hour to 45 minutes for lunch.

    When you have an off road van or using one in a 4WD you may be climbing a steep grade or on a severe sideways slope for more than 20 minutes and this is where the problems with the 3 ways come in. It is why compressor fridges are the ones recommended for off road vehicles and vans.

    Being an older technology the 3 way are also less efficient than compressor fridges.

    Hello from Brisbane.

    Don't know much about fridges, but I genuinely endorse your test agent. Great stuff.

    But, you can do better than a Weis bar by going down the DIY route.

    Years ago when Singleton was still a cow town rather than a mere mine.... the cafe opposite the old Dunolly Bridge - probably called the Bridge Cafe - made their own frozen fruit salad bars. Basically, a can of Golden Circle fruit salad topped with home made ice cream, frozen in trays and cut into blocks, wrapped in grease proof paper. If there were kids on board, my Dad and uncles used to pull up in the truck and buy a bag full on the way home from the saleyards.

    Apologies to anyone who got sprayed by the cattle........

    Cheers,

    Cheers,
    Been there, at least when loading our own cows. Always makes me laugh when someone in a convertable car with the top down or off will drive up beside a cattle truck at the stop lights. I don't always get a laugh at the unfortunates in the car, but it's enough that it's occasional!

    As for the Bridge Cafe, our nanny state health inspectors would probably rule the home made items unsanitary these days!

    I have never had a problem with the 3 way fridges in my caravans. I run 12v for transit and gas for when we stop for long breaks. Our fridge mostly runs on gas except for the rare times we spend in caravan parks.

    And so did I until it exploded.

    If you don't level, it is not a case of "if" it is a case of "when".

    The coils develop a high spot which stops the thermal cycle flow and the refrigerant boils at that point. This creates an overpressure event and ruptures the sealed coil system. Not unlike an explosion, but not something that blows the fridge apart, only the business end of the fridge explodes/ruptures and fills the fridge and van with stinking ammonia.
