[esp-r] Re: Infiltration/ventilaton temperature

[Georgios KOKOGIANNAKIS]

Simon,

if I understand correctly:
1) You have 2 zones: one for the ground heat exchanger plus another one for your living zone.
2) For the ground heat exchanger zone you know the "internal" zone temperature.
3) You also know the outside air temperature or you have a climate file (to provide the 0.3 ach)
4) You want to control the air flow from the ground heat exchanger and from the outside into the living zone based on the sensed temperature of the living zone.

please correct me if I did not understand your problem correctly. For what I just describe you need to:
1) Use the "Impose measured data" to impose the pre-calculated temperature into the ground heat exchanger zone (use SETPTTT item).
2) Use the same facility (but different item) for your outside climate if you do not have a climate file and you instead have measured data.
3) Create an air flow network between your heat exchanger, the living zone and the outside environment.
4) Apply the appropriate air flow network controls

Best regards,
Georgios

Subject: [esp-r]  Infiltration/ventilaton temperature

Dear all,

I would like to simulate use of ground heat exchanger for air for ventilation of my thermal zone. So I have time dependent temperature for 8760 hours, for flow which could enter into simulated zone from ground heat exchanger, which was calculated in other software (txt file). I have also 0,3 ACH of infiltration into the thermal zone with outside ambient temperature. So Idea is to have ON/OFF flow control with temperature sensor in zone.

I can’t figure out how to setup the model to run such case. I tried with “Impose measured data” facility without success. Any hint or idea will be appreciated.

Thank you in advance.

Simon Muhic
