Webinar Poll:  Which Topics Related to Air Quality Interest You the Most?

On December 9th, 2020 at 11 AM CT //  4 PM GMT: Honeywell will Discuss Air Quality:

 

Honeywell will be giving away 2 HAQ Air Quality monitors for asking the best questions during this webinar.   Furthermore, they are interested in which topics related to HVAC interest the community the most.  Don't see a topic that interests you? Let us know in the comments below!

  • A couple of thoughts on this.  I did attend the Honeywell webinar, and learned some things.  On climate change, my first thought is about how much electricity it takes to compress refrigerant gases in the air conditioning cycle.  But as they pointed out, the old refrigerants have a much higher warming factor that CO2.  Even newer R-134a has a high GWP of 1400 (1400 times equivalent CO2).  So the industry trend is toward hydrocarbons, which work well but are flammable, so therefore the manufacturers have to take flammability into account when designing their sensors.

     

    I like the idea of cycling the systems to beat back viruses by making the environment less favorable.  One of the reasons Covid-19 came up is because the webinar talked about HEPA filters and whether that could reduce virus particles in circulation.
