NC-2009 EAp2:Minimum Energy Performance

Humidification Plant load

Dear All:-

We have large manufacturing facility with Humidification plant & Chiller

The Electrical load of this Humidification plant is about 3000 kW (supply, return fan, Water supply pump) and it is work with a help of 3000 TR VAM Chiller

Now we have doubts in Model this Humidification plant in both case

1.How can we model this humidification plant Load of 3000 kw either identically or not

2.The Humidification plant is working like a AHU with Humidifier with help of Chilled water so can we model this Humidification plant as AHU with Humidifier in both cases

3. Additionally we have multiple building with single chiller plant with 8 chillers there is no dedicated chiller or chiller plant for each building in this case how we prove the minimum energy saving of 18% for each building

4. The entire project have CHP and it is serving to LEED scope buildings so can we use this CHP to prove the minimum energy saving of 18% for each building

1. How you model it is software specific. Keep in mind that you model the system identically. Sometimes the energy use for such a system will vary depending on other factors. This variability is acceptable. 2. OK 3. You will need to follow the guidance in the District Energy Systems v2 to determine how you are allocating the chilled water energy use. 4. The CHP would contribute depending on how you model the plant.
