Climate simulation in the three-chamber climate simulator
Hygrothermics
| Measurement | Stationary and transient processes of thermal conductibility and humidity penetration, U-value, storage properties of building components, alternating climate loads, thermal bridges, condensation, cavity convection, vapor diffusion processes, day/night simulation |
| Measurement object | Large façade and roof elements, prefabricated house elements, door and window elements, thermal insulation by means of external shutters, roller blinds, etc., composite constructions with thermal bridges, multi-layer building components with cavities, charging and discharging cycles of heat storage facilities, equipment for ventilation, heat recovery installations, absorber elements |
Technical data
| Internal size (L × W × H) | Chamber 1 and 2 2.0 × 4.0 × 2.7 m Chamber 3 2.4 × 4.0 × 2.9 m |
| Temperature range (chamber 1 and 2/chamber 3) |
−30 up to +80 °C |
| Humidity range (chamber 1 and 2/chamber 3) |
