Only 2–3% of the total air volume is induced (“pulled along”) in the product, which leaves enough space for the extracted air to remove heat and pollutants.
No, not really. We tend to say: “As long as you aren’t hitting your head on the ceiling, you have an advantage over a mixing system!”
It depends entirely on conditions such as air volume, air pressure, temperature, choice of product, etc. Generally, a product with isothermal air (with low air pressure and flow) reaches approximately 2–3 times the ceiling height into the room. With sub-temperate air and heat sources in the room, this figure will be higher.
Yes, that is correct. In particular, from the person in the room, if the volume of air and temperature supplied to the room remain the same. If you want to reduce the temperature of an object/person/room you must allow heat to be given off.
In Sweden, the Work Environment Authority has issued regulations entitled “Workplace design: Provisions of the Swedish Work Environment Authority on workplace design and general recommendations on the implementation of the provisions (AFS 2009:2)” These advise that 7 l/s of airflow should be supplied per workplace, with 0.35 l/s of airflow per square metre in an office environment.
