For heat recovery ventilators (ii RV) 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 />019 <br />REVIEWED FOR CODE <br />COMPLIANCE CITY OF ORONO <br />24 <br />
