Air Conditioning and Ventilation during the COVID-19 outbreak

Advice has been published by HSE with regard to Air Conditioning within buildings.

HSE say that the risk of air conditioning spreading coronavirus (COVID-19) in the workplace is extremely low.

It is advised that you can continue using most types of air conditioning system as normal. But, if you use a centralised ventilations system that removes and circulates air to different rooms it is recommended that you turn off recirculation and use a fresh air supply.

You do not need to adjust air conditioning systems that mix some of the extracted air with fresh air and return it to the room as this increases the fresh air ventilation rate. Also, you do not need to adjust systems in individual rooms or portable units as these operate on 100% recirculation.
