Indoor model parameters ¶

Overview ¶

Since r31xx an indoor climate and energy demand model is available in PALM.
The indoor climate and energy demand model based on the DIN EN ISO 13790:2008 with simplfified dynamic hour-based procedure.
This model is a equivalent circuit diagram of a three-point RC-model (5R1C). It take account to following parts:

• different zoned building physical properties (material, building year...)
• transmission and solar heat gains (with reduction by sunprotection)
• different ventilating properties (for scheduled empty and occupancies rooms)
• different internal heat gains (for scheduled empty and occupancies rooms)
• thermal comfort requirements (air change, target temperature)
• heat recovery factors (effiency of heat recovery)
• plant irreversibilities

This module differ between indoor-air temperature an average temperature of indoor surfaces which make it possible to determine thermal comfort.

Working in progress:

• output of heatfluxes and indoor temperature in netcdf data
• reduce the building volume to netto ground surface to take respect costruction areas like walls and ceilings.
• emmisivity change through window blinds because of sunprotection
• make spinup run possible
