internal gains in a computer lab

[Ciaran M]

very basic question, however, im trying to simulate the thermal gains from plug loads in 2 computer labs in Apachesim, ive inputted all relevant data into internal gains with regard to occupancy levels and number of computers. my issue arises in that im unable to find my results in Vista. Can anyone give me some direction on where i should be looking

Hi,

Couple of basics to start off

- did you assign the gains to the rooms (either directly or via thermal templates)?
- in simulation settings >> output options there is an option to switch on the internal gains breakdown, without this you will only have a generic internal gain variable to review
- what results are you looking at? If you are looking at a sim results file and the above is done then choose a room and in the room variables you will find your different gains all listed out as separate variables, you can type gain into the filter to see these

Thanks Phil, I think ive sorted it now, I ended up simulating the rooms separately, as I couldn't work out how to assign the separate internal gains to 2 individual rooms. I was only setting up one thermal template for the 2 rooms.

Thank you Phil.
I have one further question, the building also contains a heat redistibution system. this system consists of Daikin wall mounted AC units set to cooling only in the computer labs where the heating is supplied by a single pipe heating system, therefore it is always on. in addition to the internal gains of the room, this results in a massive over supply of heat. there is an external condenser on the roof, connected to floor mounted AC fan heaters in colder rooms in the building. Im having difficulty modelling this in Apache HVAC, any suggestions would be appreciated.
