Refrigeration Heat of Respiration Load (\( Q_r = \frac{W_p \cdot HR_p}{86400} \)):

Where:

• \( Q_r \) is the heat of respiration load, in watts (W).
• \( W_p \) is the weight of the product, in kilograms (kg).
• \( HR_p \) is the product heat of respiration, in joules per kilogram per day (J/kg-day).
