Freezer Question

[Fintray]

Yes it is.

Would it be possible to send me some of the data and a description of what type of charts you were hoping to get?

Sure, PM me your email I'll send you the file over.

No chance! The next generation of freezers will probably sense the mains frequency and switch on when demand on the grid is low, ie when the frequency rises slightly. This coupled with a Very Smart meter will give the consumer a variable tariff.

So far this freezer has taken nearly 17 hours to freeze 3 litres of water, and the outside panels feel quite cold, so unless I can add extra insulation I doubt whether my Cunning Plan will work.

Are you able to see how far down on the inside of cabinet the tubes are freezing up, is it just a couple of turns by any chance. and put a thermometer in it instead of bottles of water. bottles of water aren't very good at telling you the temperature

They seem to cover the sides pretty well, the outside panels cool down evenly.

Thermocouples don't make good coffee either.

I've set the thermostat to switch between -14 and -9 degC. My counter-top freezer registered -10 and I've had no problems with that, and ice cream came out rock hard. I'm keeping the ice cream at the top of this one, and putting new stuff at the bottom.

Ice cream are normally quite soft at those temps as ice cream is one of the first things that will give you an indication that your freezer might be on the blink. You do have a thermometer then ?.

 

[rtbcomp]

Ice cream is easy to spoon out direct from the shop, but after an overnight stay in my old freezer it was rock solid, this spoils the taste too.

I've got a freezer thermometer and a thermocouple on my multimeter.

Just left the fast freeze switch on overnight. Temperature was down to -17 from -12 in the morning with condensation streaming down the outside of the cabinet.

If it was in good condition I would have expected it nearer -27 than 17 if left to run overnight.

 

[rtbcomp]

Me too, especially as it's only 12 months old. It didn't switch on until about lunchtime, so 7 hours on at half-price and 4 hours off gives a slight saving.

There's a lot of condensation on the outside, personally I think it's an el-cheapo. The firm have gone bust recently, they blame the demise of Comet, but they didn't get very good reviews.

I'm going to put an extra layer of insulation on the outside to see if that helps. On my other freezer I fitted a fan to cool the motor down, I'm sure that helped too.

Has it got a condenser on the back, if it has you will be ok to pin on more insulation, plus put some over your food under the hatch.

I said to our lass I was going to get rid of the freezer and keep a pig. We'd just have to cut one leg off at a time

There's a lot of condensation on the outside,.

I think that means that the barrier around the space containing the insulation has failed and it's become waterlogged internally. Insulation no longer doing its job to an acceptable degree hence the condensation on the external surfaces.

Not sure on that one, what does it look like and why is it significant?

It does in the instructions that it's normal for the outside to feel cool.

Apparently the insulation is injected foam rather than rockwool type.

The condenser is the black radiator you see on the back of fridges, its where the compressed gas condenses back to a liquid and gives off the heat its extracted from the inside space. if it has one then you can add insulation to the sides if not then the condenser tubes will be stuck to the inside of the outer cabinet skin and gives off its heat through that outer skin, if you cover it up with insulation then it can not condense, which basically means if it cant give up the heat it cant take it away, so no heat transfer.

 

[rtbcomp]

Ah yes it has the radiator on the back. I dismantled a large chest freezer which had the hot coils attached to the outer casing.
