[Equest-users] Evaporative cooler modelling

[Prasad Wani via Equest-users]

Dear All,

I am modelling Indirect-Direct Evaporating cooling system with *constant
volume *and *continuous *setting. The minimum and maximum supply flow ratio
is *1. *The OA fraction is also 1.

The pump & secondary kW value is *0.00015 kW / cfm. *This parameter is used
for space cooling.

With the above settings, energy consumption for *ventilation fan* is
constant. However, the *space cooling energy consumption *is *different *for
each month. The screenshot is as follows:

Why the space cooling energy consumption is *not same for all months *even
when constant value of 0.00015 kW / cfm is given as input?

Kindly guide about this.

Thank you

Regards,


Prasad S Wani
