[TRNSYS-users] Air cooled heat exchanger that considers sensible and latent heat

[Jeff Thornton]

Young-Il,

To be clear,  are you cooling the liquid with air, or cooling the air with liquid? 

1 - If you are cooling the liquid with air, the air temperature will rise and there will be no latent impact on the air stream if the two fluids are not in direct contact with each other and there is no water injected into the air.  This is found in the library as a heating coil or a dry fluid cooler.

2 - If everything is the same as 1 but the liquid is undergoing a phase change, look for an air cooled condenser model.  

3 - if everything is the same as 1 but you’re injecting water into the air stream then look at the cooling tower models as my esteemed colleague Dr David suggests.

4 - if everything is the same as 1 but some of the water is evaporated in the process, look for an adiabatic saturation model or a “swamp cooler” model.

5 - if you are cooling the air with the liquid then look for a cooling coil model or an evaporator model (phase change on the non-air side).

We can help you choose if you give us more information as to what you are trying to do.
