Design of condenser 1. Introduction. A condenser is a type of heat exchanger in which vapors are transferred into liquid state by removing the latent heat with the help of a coolant such as water. Condensers may be classified into two main types: 1.

A surface condenser is required to deal with 15 000 kg/h wet steam. Wet steamtemperature is 37 C and enters the condenser with 0.95 quality (dryness fractionis 0.95). The water used for cooling has the following data:
- Inlet pressure 1.20 bar, inlet temperature 7 C
- Outlet pressure 1.013 bar, outlet temperature 22 C
Calculate the flow rate of cooling water and tube surface of the condenser.Assume that the cooling water velocity through tubes is 1.5 m/s

I want to learn to design surface condenser base on HEI standard, I would be very grateful if someone can tell me how I should start learning it?
Is there any software for designing surface condenser based on HEI standard (Like HTRI or Aspen EDR that are based on TEMA Standard)? ( I googled it but I could not find anything)
Does the HEI standard is enough for design calculation or I need another reference (book or handbook) ?( if another reference is necessary please let me know)
It would be very helpful if you could send me an example of designing surface condenser because I really don't know what I should do or what book or Handbook I should read.
Best regard,
