ERV/HRV Fan Efficacy cfm/watt
I am trying to help a client fulfill the New York 2020 Energy Conservation Construction Code ERV/HRV fan efficacy requirement of 1.2 cfm / watt.
The HVAC company has spec’ed out a Fantech ERV, but none of their units that I can see will meet the requirement. I suggested a Mitsubishi LGH-F300RVX-E which handily meets the requirements, but they are balking at the extra cost.
Any suggestions for an ERV/HRV that may meet these requirements? Looking for something that at 100 cfm, uses less than 83 watts. My guess is that only ECM motors will do the trick.
Thanks in advance.
