---|
| 53 | !> Module for Indoor Climate Model (ICM) |
---|
| 54 | !> The module is based on the DIN EN ISO 13790 with simplified hour-based procedure. |
---|
| 55 | !> This model is a equivalent circuit diagram of a three-point RC-model (5R1C). |
---|
| 56 | !> This module differ between indoor-air temperature an average temperature of indoor surfaces which make it prossible to determine thermal comfort |
---|
| 57 | !> the heat transfer between indoor and outdoor is simplified |
---|
| 58 | |
---|
| 59 | !> @todo Replace window_area_per_facade by %frac(1,m) for window |
---|
| 60 | !> @todo emissivity change for window blinds if solar_protection_on=1 |
---|
| 61 | !> @todo write datas in netcdf file as output data |
---|
| 62 | !> @todo reduce the building volume with netto ground surface to take respect costruction areas like walls and ceilings. Have effect on factor_a, factor_c, airchange and lambda_at |
---|
| 63 | !> |
---|
| 64 | !> @note Do we allow use of integer flags, or only logical flags? (concerns e.g. cooling_on, heating_on) |
---|
| 65 | !> @note How to write indoor temperature output to pt array? |
