The reason of shortage for heat supply of plate heat exchanger:

1.Weak flow on hot side, large temperature difference and low pressure drop.

2.Low temperature on cold side, and low temperature on the end of hot and cold side

3.Unequal flow distribution in combinated parallel running plate heat exchanger

4.Severe scaling inside of heat exchanger

The solution of shortage for heat supply of plate heat exchanger:

1.Increase the flow of heat source and tube diameter of heat medium

2.Balance the flow distribution in combinated parallel running plate heat exchanger

3.Clean the plates
