1，Reasons for system configuration. Plate heat exchangers only play a role in heat conversion and follow the law of energy conduction, that is, the heat released by the hot side is equal to the heat absorbed by the cold side. In many cases, the heat from the heating system on the hot side does not have enough cooling water on the cold side. Take it away, such as insufficient water and insufficient water temperature, resulting in the hot side temperature not coming down. If this is the reason, no matter how big the heat exchanger is, it is useless.
2. The reason of the plate heat exchanger itself. Many users only provide the heat exchange area when purchasing heat exchangers, without specific data such as heat exchange amount, medium flow rate, inlet and outlet temperature, etc. As a result, although the model area of the plate heat exchanger is correct, the process combination is unreasonable. It also fails to achieve the desired effect, even if the area is increased on this basis, it is useless.
Therefore, when selecting the plate heat exchanger, you must find a professional manufacturer to verify the working conditions.
