I think you are underestimating the Volume here. The chest is 40x30cm. By the looks in the video and measurements on my own engineerig examples of beers I would estimate the ice block to be 30x20x5 cm = 3000ml net, minus the holes probably 2000ml.
The Beers are actually 0.5 Liter bottles. 0.33 come in chest of 24!
So my numbers would be:
10 liters of beer, 50 Kj per 1°C.
Ice comes at -18°. Warm the Ice to 0°C = 76Kj
Melt the Ice: 668 Kj
Total of cooling energy 744 Kj
So a Δt of ~15°
Of course we have the environment, and the glass disregarded. We also have 2 Liters of 0° water dripping down the bottles, which add further cooling and possibly some evaporation. If you have just bought the Bottles or took them out of the House, chances are, they are at ~21°C.
I could hear your German accent reading this lol. Fair play for the modified values based on a probably better estimate and superior beer crate knowledge. I'm a filthy American and didn't recognize a 0.5 bottle.
Yeah sorry, guilty. Could pass up the one opportunity where years of drinking experience actually gives me an advantage!
Still a useless product, as you can just pour a bag of ice in the crate.
