    Telecoms Equipment room Cooling

    I should add heat from people who are working there and I think it is a good idea to do calculations with peak temperatures (during summer and winter). Yes, you should add a safety margin to final result and also a correction factor for the evaporator.

    TO: Quark Yes, You are right, I've made mistake in calcs about the output temp of air at coil exit. The real values are: 15C/97%RH or 19.3217 BTU/lb. So the calcs are: 100% fresh air: 4.5*(47.1503-19.3217)*370.8=46434.802 90% recirc air: 4.5*(22.1977-19.3217)*529.72=6855.636 This means...
