Frequently asked questions

What is the purpose of ventilation?

Ventilating your buildings is important because it removes the stale, moist air from inside the building with fresh clean air from outside, providing a comfortable environment at work or even at home.

Why is ventilation necessary?

Ventilation is necessary to control a room’s temperature, oxygen supply, deodorization, and dehumidification. It is said that in an unventilated room, CO₂ levels rise, making it difficult to concentrate and making people sleepy.

How often should I ventilate a room?

Aim for twice an hour, between a few minutes to 10 minutes per time.

How important is ventilating while sleeping?

Don't forget this one. Ventilate when you sleep. It is said that CO₂ levels increase in a closed bedroom, which affects one’s quality of sleep. Even just opening the bedroom door a little bit can help, however for a full solution, our domestic range of Lossnay units can provide an optimised environment for sleep.

What is the difference between HVAC and ventilation?

HVAC stands for Heating, Ventilation and Air Conditioning, therefore there isn't a 'difference' between ventilation and HVAC. Ventilation is an important part of any HVAC system that ensures a supply of fresh, clean air.

Why Indoor Air Quality?

It is a sobering fact that around 92% of our day is now spent indoors, so it’s vitality important that we recognise that indoor air quality (IAQ) has a major effect on our overall welfare.

At Mitsubishi Electric we’ve been working with the Building Engineering Services Association (BESA) to provide the general public with an informative guide to improving IAQ in all different types of buildings. It’s great to be able to say that our joint work on what is now a subject of unprecedented public interest has recently been endorsed by high profile child health campaigner and World Health Organisation advocate Rosamund-Adoo Kissi-Debrah.

Feel free to download the guide and please pass it on to your customers or keep for reference, we hope you find it useful.
