For heat recovery ventilators(HRV)and energy <br /> recovery ventilators(ERV)the average hourly ventilation capacity must be determined in consideration of any reduction of <br /> exhaust or out outdoor air intake,or both,for defrost or other equipment cycling. <br /> Continuous ventilation-A minimum of 50 percent of the total ventilation rate,but not less than 40 cfm,shall be provided, <br /> on a continuous rate average for each one-hour period. The portion of the mechanical ventilation system intended to be <br /> continuous may have automatic cycling controls providing the average flow rate for each hour is met. <br /> l:\Building\SafetyPoliciesinformation\Current\2016\VentMakupCombAirCa ls2016.docx <br />
