Given the inlet and outlet temperatures and flow rates of water and hot water, how can the heat exchange area of a plate heat exchanger be calculated?
This is the same as the area calculation formula for other types of heat exchangers. First, calculate the total heat transfer amount and the temperature difference. Assume a heat transfer coefficient; for plate exchangers, a value of around 1500 is typically used. Once the heat transfer area is determined, the exchanger can be designed. For the designed heat exchanger, the heat transfer coefficient can be calculated again.
Each manufacturer has different models, and the overall heat transfer coefficient also varies; it should be calculated by the manufacturer.
