How E+ calculate the ventilation loads ? And What is the output ?
I am working with the hvac templates : dedicated outdoor air. I am using this templates like an AHU with heat recovery. Supply air : 20m3/h/pers. Efficiency of my heat exchanger : 0.75
I would like to know what is my ventilation heat gain, in watt. I would like to see the effect of the heat recovery on the cooling capacity of my room compared to outdoor air.
What output do I need to ask in E+ ?
Zone mechanical and air system, its only energy so in J, not really what I want.
I tried "Zone Air Heat Balance System Air Transfer Rate", I dont know what is included inside but I dont think its the good output.
I also tried "Zone Air Heat Balance Outdoor Air Transfer Rate" but it is for infiltration.
Outside of E+, I am used to calculate the ventilation heat gain with this formula :
- Sensible : airflow * difference of T * 0.34 * efficiency of my exchanger
- Latent : airflow * difference of humidity * 0.84 * efficiency of my exchanger
Does Energy+ calculate the ventilation heat gain in the same way ?
Link of my inputs, perhaps it could help to understand :
