Is it possible to simulate outdoor thermal comfort using the tools to also account for spot cooling, or jet diffusers in an open outdoor?
You can definitely assess outdoor comfort with ladybug. In particular, the Universal Thermal Climate Index (UTCI) model used by the Outdoor Comfort Calculator is probably one of the best models for outdoor comfort.
The UTCI model has the following inputs:
- Air temperature
- Radiant temperature
- Relative humidity
- Wind speed
If you know the impact that your just diffusers have on the air speed and temperature that the human subject experiences, then you can use the UTCI model to assess how much more comfortable people are in those conditions.
thanks for the reply chris. i was hoping to assess the range of spot cooling to be able to place the diffusers better, instead of applying an overall temperature on the open space since its quiet large
Modeling how spot cooling works is a totally different question. For that, you would need to describe how your spot cooling apparatus is intended to work in the first place. For example does it only use radiant cooling? In that case, how do you control the humidity and prevent condensation on the radiant surface? Does it try to cool the air? In that case, how do you contain the cold air and prevent it from blowing away? Does it use a fan? In that case what flow rate or speed is the fan designed to?
