[Equest-users] Heating and Cooling Loads per Hours for a thermal zone

[Sharad Kumar]

Hi Konstantina,


I would like to suggest the theory behind the scene.
The sensible load comes in eQUEST by the following super-headed things:

1. Occupancy
2. Space lighting
3. Equipment loads
4. Outside area space heat gain.
5. Infiltration

Latent heat in my sense comes from:

1. Occupancy
2. Infiltration.

Now the sensible heat gain is the real temperature value to be going high.
Now the 5 cases are like the occupancy heat gain from the person is the
real cause for the sensible load to be parting up in the temperature going
up.
Space lighting and equipment load has some part as the fraction of input
LPD , EPD part to behave as the sensible load which is drawn from the real
input with sensible heat gain fraction to the space.
Outside area gain and the infiltration gets involved with the outside heat
to get transferred in the space and make the temperature higher.


Latent heat is the heat from occupants and the outside heat infiltrated air
to come inside the room with moisture to let the wet bulb temperature to be
going higher,
The heated moisture is the cause to behave the wet bulb temperature to go
higher as the WBT is dependent upon the moisture temperature of the room.

Now as per your query if the sensible heat load is greater than 0 than the
inside air will have higher temperature to get cooled and hence there will
be sense of cooling load.
If the sensible load is smaller than 0 than there is requirement of heating.
Others input might also help.

Subject: [Equest-users] Heating and Cooling Loads per Hours for a thermal
zone
Hello to all equest users,

I am searching the Loads (Total Losses and Gains) of a thermal zone per
hour.
I did following step (see screenshot)
[image: image.png]
If the Sensible Load is >0 then It is a cooling load,
if it is <0 it is a heating load.

For all the building I can see all the information per hour  concerning
loads for the thermal zone I can't find more information.

Do you have a suggestion or comment?

Thank you very much.
I appreciate all the help I get from this forum

Best Regards
