Ventilation heat loss

Estimate the heating load associated with outdoor-air ventilation and heat recovery.

Outdoor airflowm³/hUse the design or measured outdoor-air rate.

Indoor temperature°CThe indoor heating setpoint.

Outdoor temperature°CThe outdoor design condition for this estimate.

Sensible heat recovery%Use a tested value appropriate to the operating condition.

Load without heat recovery

1.25 kW

Load after heat recovery

0.31 kW

Constant dry-air properties, balanced airflow and sensible heat only. Fan electricity, infiltration, defrost, leakage, humidity and equipment performance changes are excluded.
