Plate heat exchanger calculation
Thread Content
1. Cooling plate heat exchanger: Plate type, water-to-water, 1.0/1.0 Mpa. Supply water temperature on the primary side: 3.8°C; return water temperature on the primary side: 11°C. Outlet water temperature on the secondary side: 6°C; inlet water temperature on the secondary side: 13°C. Heat transfer capacity: 2000 kW.2. Heating plate heat exchanger: Plate type, water-to-water, 1.0/1.0 Mpa. Supply water temperature on the primary side: 90°C; return water temperature on the primary side: 70°C. Outlet water temperature on the secondary side: 55°C; inlet water temperature on the secondary side: 45°C. Heat transfer capacity: 2800 kW. Please help calculate the heat exchange area
First, it should be the heat balance in terms of processing. This heat exchange area is the effective heat exchange area, and the design and size of the heat exchange equipment should ensure such an effective heat exchange area. There should be standards regarding the heat exchange area of plate heat exchangers.

For a capacity of 2000KW with a cross-sectional area of 238 square units, the BR10K model from XX Company’s plate heat exchangers can be used; for 2800KW with a cross-sectional area of 37.6 square units, the flow rates on both sides differ by a factor of two, so it is important to choose heat exchangers with different diameter sizes. Such as the BBR04K model used in the plate exchanger of XX Company.
1. Heat transfer coefficient: 3753, heat exchange area: 253.9㎡ 2. Heat transfer coefficient: 3355, heat exchange area: 28.08㎡
