Extends from Buildings.ThermalZones.ISO13790.Validation.BESTEST.Cases6xx.Case600 (Case 600FF, but with dual-setpoint for heating and cooling).

Information

This model is used for the test case 650 of the BESTEST validation suite. Case650 is the same as Case600, but with the following modifications:

  • From 18h00 hours to 07h00 hours, vent fan = on
  • From 07h00 hours to 18h00 hours, vent fan = off
  • Heating is always off
  • From 07h00 hours to 18h00 hours, cooling is on if zone temperature > 27°C, otherwise cool = off.
  • From 18h00 hours to 07h00 hours, cooling is always off.
  • Ventilation fan capacity is 1700 standard m3/h (in addition to specified infiltration rate). After adjustment for the altitude, the capacity is 1409 m3/h.
  • No waste heat from fan.
