Powerful ventilation from fresh air, with the windows closed.
The amount of air a person breathes in an hour is about 600 L*3.
When the whole family is gathered in the living room, you want to make sure there is plenty of fresh air.
Ururu Sarara's fresh air supply ventilation function is powerful enough to completely replace the air in a room*1 measuring approximately 26 m2 in two hours. It can quickly ventilate spaces like a living room, where the whole family gathers, by pumping in plenty of fresh air. You can use Ururu Sarara as a replacement for a conventional ventilation fan.
During fresh air supply ventilation operation, outdoor air is taken in by the outdoor unit, warmed by the indoor unit during heating operation and cooled during cooling operation, and supplied to the room. Unlike conventional ventilation fans, this system prevents hot or cold air from entering through gaps under doors and the like.
*1. Ceiling height of 2.4 m
*2. Measuring conditions as specified in Japan Refrigeration and Air Conditioning Industry Association standards (JIS B 8330 compliant). Measuring conditions: Standard ducts, hose length of 5 metres with 5 bends (including indoor connection cuffs) and open to the outdoor air. Airflow volume drops under certain installation conditions and usage conditions.
*3. Assuming that an adult at rest takes into the lungs 0.5 L of air per breath (10 mL/kg and body weight of 50 kg) and takes 20 breaths per minute (0.5 L x 20 breaths x 60 minutes = 600 L). These figures are calculated based on normal food intake and maximum lung activity and number of breaths. Actual results may differ due to factors such as type of activity and temperature.
