I was able to successfully create a simple working component using g95. If
anyone else requires assistance with this, I can help out as much as I am
able. My email address is urbanej at appstate.edu

> Sebastian,
> I would think that all you would need would be Type56 and Type109 (plus
> Type33 and Type69 I think). You can just set the cooling temperature in your
> zones to 24.2C and allow the cooling equipment to have unlimited power, then
> take a look at the maximum cooling load that was required. That should give
> you the required system size. Keep in mind three things:
>
> 1. Type109 reads a typical (average) weather year file - not an extreme one
> and typically (right or wrong) system sizing is done based on a worst-case
> scenario, not on an average year.
>
> 2. If you plan for your lab to have temperature setups and setbacks, your
> max cooling load will be enormous because technically the load is infinite
> when your set point temperature comes back from its set up condition. I
> would recommend using a constant setpoint in order to find your system size.
>
> 3. The Type56 output QSENS is sensible cooling only! In order to get a
> latent component, you must also impose an RH setpoint on the zone and look
> at the QLAT output from Type56. This isn't ideal because often the latent
> cooling is an effect of the sensible cooling (not something that can be
> controlled separately). We wrote a component based on some curve fits that
> calculate the amount of latent cooling that a "cooling coil type" of cooling
> device can do based on zone temperature and ambient wet bulb (If I am
> remembering correctly). Its latent cooling ability turns into a negative
> moisture gain on the space, which is fed back to Type56. The component will
> be part of the TESSLibs 3.0 but for the moment is an individual component.
