RE2020 data sheets – Samarat ceiling fans
Edibatec integration with regulatory thermal calculation software
Integration with Edibatec is already in place for Perrenoud, Climawin and Pleiades-Comfie.
It is underway for the other RE2020 software.

Characterisation of ceiling fans in RE2020
Ceiling fans are modelled taking into account the following elements:
- A ceiling fan component is created for each type of ceiling fan.
- Only one type of fan is permitted for a single partitioned room
- The air speed in an area covered by fans of a certain model is proportional to the mixing ratio in that area.
- The calculation applies to ceiling heights of less than 3m.
- For ceiling fans of the same model, the same management/regulation is applied, without knowing the exact location of the occupant.
- The maximum surface area served by an air blower is 15 m².
- Ceiling fans can only be operated during cooling periods.
Entries are made at group level.
Ceiling fans can only be used in non-air-conditioned units.
Data to be entered in RE2020 software
The input data is as follows:
- number of ceiling fans: depending on the number you specify for the zone in question[i]
- type :
- for regular Samarat, manual management
- For versions of Samarat fitted with a thermostat, select “automatic management with thermostat”, and enter the values below:
- Δθop1 : 0°C
- Δθop2 : 2°C
- Δθop3 : 0°C
- type of use : day/night/day and night
In the current state of our information, the type of use is based on the actual use of the given room. For example, an office is used during the day, a bedroom at night. A room that is also used as an office (e.g. a studio used for teleworking during the day) could benefit from day and night mode.
Only residential buildings can have night-time or mixed uses
- % of usable floor space occupied by rooms of a given type of use: the value is capped at 15 m² per fan maximum
- of usable surface area covered by identical fans : 100 %
- Maximum fan electrical power : 42.42 W – justified value
- Maximum fan speed : 11 882 m3/h – justified value
