You are calculating the rate of Heat Loss for Ventilation in a residence using the formula: qvent = 1.08 * VR * Delta T You are installing a Heat Recovering Ventilator. The unit's Efficiency Rating is 90%. Your calculation resulted in: qvent = 280 Btuh (.28 kBtuh) Respond: A. What will be the rate of Sensible Heat Loss with this Ventilation System? B. Over the course of a Heating Season (Nov. through April), how much Sensible Heating Energy will be recovered? Note: Assume 730 hrs. of operation for each of the six winter months. C. If Space Heating is done with Natural Gas (100 kBtu/Therm) and Natural Gas costs $23.02/therm, what will be the savings effected by the HRV over the November to April Heating Season
