Select the best response. Consider: You have calculated the Ventilation Rate of Heat Loss based on ASHRAE 2013 recommendations. You used the formula: qvent = 1.08 * VR * Delta T This resulted in: qvent = 3800 Btuh The HRV you are planning to install is rated at 90% efficiency. What will be the rate of Sensible Heat Recovered with this system? Select one: a. 3420 Btu b. 380 Btu c. 380 Btuh d. More information is needed. e. 3420 Btuh
