Re: [EnergyPlus_Support] evaporative cooling

Exactly.  Some evap systems have a pump, others do not.  The system I'm most familiar with doesn't use a pump, so I forgot about that.  Thanks for the reminder.

Including the electric energy consumed by the water circulation pump.

Best,

Eduardo,

There is NO cooling energy for an evaporative cooling system.  The only energy for HVAC is the fan.  That's the beauty of the system. 

Evap cooling does not work for all climates; only those that are fairly dry.  Even for a dry climate, sometimes there are weeks or months which are fairly humid and during which you may have a large number of unmet cooling loads.  Nonetheless, it can be an excellent system; lots of fresh air and very good comfort for many locations.

Dear Jim

I would like to know energy comsumption in order to compare the comsumption with VRF System and a evaporative cooling. For VRF system I will have HVAC power (cooling and Heating). For evaporative cooling I will have only comsumption for Heating (if I have a eletric resistence). I did'nt find fan energy comsumption.
How could I compare the energy comsumption for the both situations?

Best regards,
Eduardo.
