In a heat exchanger, how much better will copper tubing work than pvc?
Answer:
*PVC comes under insulating material.
*In a heat exchanger, we have to exchange the heat w.r.t. different temperature,pressures,velociti... and fluids.
Pvc will not survive.
So, there is no question of using PVC in a heat exchangers.
Read following:
Copper has a thermal conductivity value of 390 W / mK. PVC is only 0.16 W / mK.
A whole lot better,copper will transfer the heat.
Copper will work many times better than PVC. PVC will melt at elevated temps. So durability is a consideration also the copper will last much longer.
MUCH better.
You're looking to exchange heat, so you need the best thermal conducting material possible.
Copper has a thermal conductivity value of 390 W / mK. PVC is only 0.16 W / mK.

The PVC will contaminate eventually so you can't compare the two... I never heard that copper was related to illnesses as PVC is. And copper of course will endure much longer! And so much safer for the environment in general!
Copper, having a large conductivity factor will, by far, be better than PVC which has little conductivity value.
