The FCU in each individual home is made of an air filter, a admirer, a warm-h2o heating coil, a chilled-water cooling coil, and two Management valves. Each and every device has 3 supporter speeds plus a rated capability of 1600 W for each heating and cooling at nominal values (Desk 2). It recirculates place air but is also continually provided with refreshing air with the central mechanical ventilation system at a move charge of 60 m3/h at style temperature and humidity. A similar quantity of air is extracted from the toilet. The h2o provide temperature in heating mode is determined by the outdoor air temperature (weather compensation perform below Regulate via the central constructing automation and Command system) and is also 70 °C under nominal working ailments at −fifteen °C outdoor, while the water source temperature in cooling manner is 9 °C.
