Refrigeration help

[katwrzes]

Hey, I am new here.

I am looking for help and hints on how to solve my refrigeration assignment.

Probably it isn't complicated for you, but my course is more building services orientated and that is the first that I came up with sizing of evaporators for coolers. Any help much appreciated.


Size the evaporator for a drink cooler designed to hold 144 cans of a drink which has a specific heat capacity of 3.2 kJ/kgK. The density of this drink is 1kg/litre. The unit is to be constructed using glass fibre insulation (k = 0.036W/mK) with x= 25mm. This task must take freshly delivered product at 32.2°C to the temperature of 3.3°C .


Many Thanks ,
