Cooling water volume, temperature (inlet and outlet temperatures)； Heat source quality and heat recovery temperature?
How is it calculated exactly? For example, just one condition can be set
For example, with a water flow rate of 300 m3/h, inlet and outlet water temperatures of 60/80°C, steam at 0.5 MPa as saturated steam, and a required condensate temperature of 95°C, these parameters can be used for selection; if the water flow rate is not known, the total heat exchange capacity can be specified instead
On the water side, sensible heat is primarily considered, while on the steam side, attention is paid to the calculation of latent heat.
Could you provide the calculation process? If the total heat exchange amount is given, how should it be calculated?
Could you provide the calculation process? What is the difference between calculating sensible heat and latent heat? Explain it to me
Simply put, sensible heat is the heat released or absorbed due to a change in temperature of an object while it remains in the same state of matter. Latent heat is due to a change in the state of matter (for example, the heat released when hot water vapor condenses is the latent heat of that vapor). Latent heat is much greater than sensible heat.
Shell-and-tube heat exchangers are the most reliable, while spiral plate heat exchangers take up less space and offer excellent heat transfer performance.
Flow rate and temperature are required; for example, in the case of a condenser, it is necessary to know the pressure and temperature of the steam. It is also important to determine whether supercooling is needed by the customer. Additionally, the inlet and outlet temperatures on the condensate side are required, and the flow rate can be calculated based on these inlet and outlet temperatures
