It recirculates place air but is usually consistently provided with refreshing air within the central mechanical air flow system in a circulation charge of sixty m3/h at structure temperature and humidity. The exact same amount of air is extracted from the lavatory. The water offer temperature in heating manner depends upon the out of doors air temperature (climate payment perform underneath Handle from the central building automation and Management system) and is particularly 70 °C underneath nominal working circumstances at −fifteen °C outside, whilst the h2o provide temperature in cooling manner is 9 °C.
