Pieter_Proot's profile - activity

We evaluate the ​impact of future climate scenarios on the performance (cooling potential & thermal comfort) of a floor cooling system coupled to a (fluid to fluid) heat exchanger that is connected to a heat pump (compressor is not active during summer = passive cooling). This whole system is connected to ​a vertical ground source heat exchanger (2 boreholes​).

Our supervisor developed typical weather files for the future climate scenario's. (parameters: outdoor temperature, solar radiation, wind ...) But no specific parameter for the ground temperature ( in future) has made and put into those epw files. We filled in a ground temperature of 13°C (for the vertical ground heat exchanger) for the current climate and validation of our model.

So our question is whether OpenStudio takes into consideration the weather files ( incl. outside temperature, solar radiation, wind ...) to adapt the ground temperature (to 100m deep) of the simulation/model or not? Or do we have to enter a new ground (probably higher) temperature for the future scenarios.

Kind regards, Pieter

I have some struggles with implementing infiltration in my OpenStudio model. If I understand it well, is infiltration the flow of air from the outdoor environment directly into a thermal zone? So this can be caused by opening and closing doors, some cracks around windows, .. ? Does the airflow caused by opening the windows also belong to the infiltration input parameter? During the summer period here in Belgium, a lot of residents open some of their windows at night or during the evening to enhance the effect of free (night)cooling. I was also wondering if there are any default values that represents a good estimate of the airflow caused by infiltration that I can use for the design flow rate ?

In my model I have implemented a mechanical ventilation, but I got the advice to also implement infiltration. I found two ways to implement infiltration into my model. Is there a difference between the two and which one I use best?

First one: space types < General < space infiltration design flow rates

Second one: Spaces < Airflow < space infiltration design flow rates
