Refrigerated dolav...mini air con unit.

[Stuart J]

I'd like to make a dolav or two into small cold stores. Secure lid on top, bolt air con unit to the side and bobs your uncle.

Can anyone see an issue with this? My biggest problem seems to be finding a air con unit small enough to cool a 1m3 space!

What's wrong with a big old chest freezer?

What's wrong with a big old chest freezer?

Looking for a temperature of around 3 degrees. Could I do that with a freezer?

I take it you want to store a whole carcass rather than cut up pieces? Otherwise just get on the facebook sell/swap sites and pick up a couple of old refrigerators. We always have two or three old ones in the shed to store lambs in for a week or two

Most air con units won't have a low enough setting. You need a fridge unit

Looking for a temperature of about 3 degrees. Would a chest freezer do that?

I would think you could put a thermostat on it to make it do that.

Put the probe in the freezer and plug the freezer into the cooling control socket. Set the temp range and the freezer comes on when it gets too warm and off again at 3°C, how much a freezer would like that I don't know. Giving it some extra insulation might help.

Very simple units, I used one to control an extractor fan on my shed trying to keep some apples cool. Set it to turn the fan on every time the temp got below 10°C. The system worked but the warmest autumn I can remember meant the fan wasn't on much!

"you ideally want to have hysteresis in the controller – i.e. it turns on chest freezer when its internal temperature goes over say 4 degrees, and turns it off again when it has fallen back down to 3 degrees. This greatly reduces the number of times the freezer compressor will be turned on/off per hour which reduces electricity consumption and wear on the freezer."

That controller I posted the link to enables you to set the hysteresis at what you want.

I've done just that with a chest freezer before, so yes it does work quite well
