Heat exchanger calculation
Thread Content
Heat exchanger design: Heat transfer medium: Synthetic conversion gas (various mixtures, with percentages). ) Inlet temperature: 380°C, outlet temperature: 60°C. Inlet pressure: 2.8 MPa. Refrigerant: deionized water; inlet temperature: 40°C, outlet temperature: saturated state. Inlet pressure: 1.0 MPa. Is there something wrong with this question? I used to calculate it for flow rate~ I’ve never done it for pressure. This is an assessment question; please give me some guidance and list the calculation formulas.

There is indeed a problem: you can’t get it to cool down, as the temperatures at the inlets for the hot and cold fluids are the same.
I agree with the person in floor 2 – why are the temperatures of the refrigerant and the heating medium the same?
Hey, OP, do you have any news? How is it going?
There is still a problem: Q = KFΔt. The value of K can be estimated, and the logarithmic mean temperature difference can be calculated. But without knowing the flow rate, how can the heat transfer amount be calculated? How to calculate area?
Without traffic and without heat load, it’s impossible to calculate
Indeed, without flow rate, it’s impossible to calculate the heat load
