Are you also think that the heat goes up and ceiling heating can’t work?
Minimum ceiling construction thickness could be 60mm but usually you should count with 120-150mm including insulation.
The advantage of this heating system is the option of ceiling cooling. In this case the water at the temperature of 17°C flows to the pipes. Warm air goes up, cold water absorbs heat and sends it through the heat pump in reverse mode to the outside. The room is cooled down by approx. 6°C and a pleasant environment is created without thorough airflow as with air conditioning. Another important advantage is the humidity stability of the environment which does not change during cooling.
Ceiling cooling works like ceiling heating. You do not have to cool rooms to a low temperature. It is enough to reduce the temperature only about a few degrees and a large cool ceiling area will provide the rest. The flow of energy is turning and all subjects including persons are cooled.
The higher the humidity in the room, the higher the dew point temperature. At a room temperature of 26 ° C and a humidity of 80%, the dew point is 22 ° C. So we set a water temperature of 23 ° C or more.
|Room temperature °C|
|Rel. humidity %||25 °C||26 °C||27 °C||28 °C|
|50 %||13,8 °C||14,7 °C||15,6 °C||16,5 °C|
|60 %||16,6 °C||17,6 °C||18,5 °C||19,5 °C|
|70 %||19 °C||20 °C||21 °C||22 °C|
|80 %||21,3 °C||22,2 °C||23,2 °C||24,2 °C|
|90 %||23,2 °C||24,2 °C||25 °C||26,2 °C|
The term Thermal Comfort we encounter has no unit, it is actually feeling. Achieving thermal comfort means that one ceases to perceive the surroundings; that he is neither hot nor cold, does not feel unpleasant draft or fast air flow, breathes well, does not dry his mucous membranes and does not perceive the influence of hot or cold objects or walls..
