How to calculate the heat transfer area of these two heat exchangers? Thank you
Thread Content
1. Stainless steel steam (170°C) jacketed heater, used to heat 1 m3 of cold water at 15°C to 50°C; pump flow rate: 3.7 m3/h, heating power: 88.4 kW, initial heating time: 30 minutes. What is the heat exchange area of this heater? ? 2. Stainless steel shell-and-tube cooler: cooling hot water from 55°C to 50°C, with a hot water flow rate of 355 kg/h; the initial and final temperatures of the cold water in the cooler are 15°C/30°C, and the pressure is 0.30 MPA. What is the heat exchange area of this heat exchanger? Or are there any heat exchanger manufacturers who can provide their product specifications? We need several sets of heat exchangers currently.

Can these two media be mixed? If possible, it’s simple: introduce steam into the water to mix and heat them together, and install a control valve on the steam pipeline. There is no need for a heat exchanger; a control valve is also added to the cooling water pipeline of the cooler.
