We talked to Edward Creedy from Mainfreight about water storage and reticulation at their Railway Lane site.

⚙️ HVAC in the time of covid

Wondering what to do with your HVAC system to prevent covid transmission?

Well - REHVA, the Federation of European Heating, Ventilation and Air Conditioning Associations - has just published some key information on the subject.

“The coronavirus particle is 80-160 nanometres (1 micron = 1,000 nanometres) and remains active in common indoor air conditions for up to three hours and two to three days on room surfaces.”

Key points include:

  1. Increase air supply and exhaust ventilation

  2. Use more window-driven natural ventilation

  3. Humidification has no practical effect

  4. Safe use of heat-recovery devices e.g. Based on current evidence, REHVA recommends turning off rotary heat exchangers temporarily during SARS-CoV-2 episodes.

  5. No use of recirculation e.g. The guidance document says virus particles in return ducts can re-enter a building if centralised air handling units have recirculation. 

  6. Duct cleaning has no practical effect

  7. Change of outdoor air filters not necessary

  8. Room-air cleaners can be useful
