For heat recovery ventilators(HRV)and energy recovery ventila- <br /> tors{ERV)the average hourly ventilation capacity must be determined in consideration of any reduction of exhaust or out outdoor <br /> air intake,or both,for defrost or other equipment cycling. <br /> Cootinuous ventilation-A minimum of 50 percent of the total ventilation rate, but not less than 40 ctm,shall be provided,on a�on- <br /> tinuous rate average for each one-hour period. The portion of the mechanical ventilation system intended to be continuous may <br /> have automatic cycling controls providing the average flow rate for each hour is met. <br /> G:\SAFETY�JK1Vent-makeup-comb air submittal(2).docx Page 1 of 6 <br />
