I have an order from consumen to made design for spiral evaporator.
I didn't know the formula for calculated that evaporator.
So i would like to ask to the forum what is the formula to calculated the spiral evaporator?

the data is :
- Cooling capacity : 36,3 kW
- Evaporating Temperatur : 0 C
- Condensing Temperatur : 45 C

the question is :
- Size for cooper tube (diameter and long) ?
- Diameter of the spiral ?
- Height of the spiral ?
- Give the dimension of the spiral evaporator ?
