vic008 17 Posted January 26, 2019 Share Posted January 26, 2019 Put in as many bags of ice as will fit? Remove the plastic bags? Keep the ice melt drained? Any other thoughts? Quote Link to post Share on other sites

Guest 000 Posted January 27, 2019 Share Posted January 27, 2019 Minimising air space is the key. A few blocks of polystyrene of differing sizes is good. Alternatively,as my wife was prone to do, fill void spaces with rolls of toilet paper. Has the additional benefit of adding to your comfort on a hot day when nature calls.

Fish 0 Posted January 27, 2019 Share Posted January 27, 2019 An interesting fact on polystyrene, relevant to keeping fridges cold. It has a very low heat capacity, i.e. it takes very little energy to heat it up or cool it down (low joules per kg of polystyrene per deg of temp change) Steel is the opposite, in that it requires a lot of energy to heat a kg up by a degree. This can be counter intuitive for people because it is used for insulation. The short story is if you fill your ice box with it, it will adsorb very little 'cold energy' in cooling down to the icebox temp, and displaces all the air, which conducts heat by mixing and convection.

marinheiro 352 Posted January 27, 2019 Share Posted January 27, 2019 Solid ice rather than cubes. Make your own using ice cream containers or similar Quote Link to post Share on other sites
Vorpal Blade 89 Posted January 27, 2019 Share Posted January 27, 2019 We make a single 150mm deep ice berg in the bottom of the large iceytek chilly bin by putting the whole thing in the freezer. A mini glacier like that usually lasts us 4 days solid form in the bottom of the drinks bin. Drinks and loose ice go on top and drain the slouch off daily, Quote Link to post Share on other sites
vic008 17 Posted January 28, 2019 Author Share Posted January 28, 2019 Well, 2 bags of ice in the 25L Willow on Sunday afternoon and this morning all melted. Hardly worth bothering with. Quote Link to post Share on other sites
harrytom 646 Posted January 28, 2019 Share Posted January 28, 2019 salt ice is way better than normal,do not open constantly and it last, Quote Link to post Share on other sites
Crazyhorse 47 Posted January 29, 2019 Share Posted January 29, 2019 salt ice is way better than normal,do not open constantly and it last, I second that. The salt has it freezing at a lower temperature and seems to last longer, the beer it keeps cool doesn't though... Quote Link to post Share on other sites
Sail Rock 28 Posted January 29, 2019 Share Posted January 29, 2019 I fill 2-3 empty milk bottles with water, freeze them at home then put them in boat’s freezer (which never actually freezes). These ice bricks help bring the temperature down and provide some thermal inertia within the compartment. Also place a foam sheet over the contents and eutectic plate to insulate them from the air gap above. Quote Link to post Share on other sites

vic008 17 Posted January 29, 2019 Author Share Posted January 29, 2019 So the chillybin a total disappointment, but will try salt ice. Looking at gasmate 3 way 35L for $500 ; or gasmate 2 way 40L $600. Apparently bit of an issue with gas burning down below being fatal, and would need to be level for the gas. What are the thoughts on the electric model? (dont understand the sudden desire for cooling) So any thoughts please? (Poor old pensioner and also not much space) Quote Link to post Share on other sites
Island Time 1,235 Posted January 29, 2019 Share Posted January 29, 2019 A really good quality chilly bin can keep ice for a week. That and salt ice work well. Quote Link to post Share on other sites
vic008 17 Posted January 30, 2019 Author Share Posted January 30, 2019 Well what am I doing wrong? 2 bags of ice barely did for 2 nights Quote Link to post Share on other sites
Crazyhorse 47 Posted January 30, 2019 Share Posted January 30, 2019 What was the OUTSIDE temperature? Been 26 here! Got an old sleeping bag and a roll of a foil? Helps. Quote Link to post Share on other sites
Marshy 30 Posted January 30, 2019 Share Posted January 30, 2019 the 3 way fridges are really only 2 way - 240v or Gas. running the small 30litre one i had on Mercenary on 12volt made luke warm beer and drew about 5 amps. If you are thinking of using battery / 12v then go a proper compressor 12volt fridge / waeco unit not an LPG / Thermotropic unit? Quote Link to post Share on other sites
Ex Babe 5 Posted January 30, 2019 Share Posted January 30, 2019 Well what am I doing wrong? 2 bags of ice barely did for 2 nights Was everything cold, and where, possible frozen before it was put in the cool box? If not you are wasting all the ice just bringing the temp down Quote Link to post Share on other sites
harrytom 646 Posted January 30, 2019 Share Posted January 30, 2019 Waeco well worth the price,I have cfx 40 and ran on temp zone 4 for 5 days away camping at thames and 120amh deep cycle battery lasted just with no charge.(need to invest in a panel)forget about the crappy old warehouse chilly bins,find an iceytek bin,near freeze or hard chill items before use.Salt ice!!

Battgirl 23 Posted January 30, 2019 Share Posted January 30, 2019 Dometic 68l bin completely surrounded by woolly R2.4 insulation and filled with 3l bottles of frozen water on top of food etc and air gaps filled with a wet bath towel and polystyrene. Food keeps cold and water stays frozen at least 5 days Quote Link to post Share on other sites
