Hello,
I was asked to replace a cabinet cooler in a small machine. The installed one is an air vortex cooler, and they want to change to standard electric refrigerating unit. The problem is that the cooling power of the vortex is rather big, so the electric unit would be too big for the cabinet.
Because of this, they want to recalculate the cooling power, taking into account the use of the machine, that is not continuous, to see if it is viable to install a new air conditioner.
I was thinking to graph the temperature versus time of the machine before and after cutting the air to the vortex, so i can take the temperature difference and the time to steady state.
then with Q=m.c.dt and watts=joule/seconds get the required cooling capacity.
The volume of air of the cabinet is approximately 0,5 cubic meter, so it will be mass 1,229kg/m3 and the air specific heat of air is 1,005.
Is that procedure more or less accurate for me to buy an air conditioner and try? Is there any other "practical" procedure? anyone have any experience installing cabinet coolers?
Thank you very much!
