Total Cooling Load Formula:
Definition: This calculator estimates the total cooling load required for equipment by considering both sensible and latent heat components.
Purpose: It helps HVAC professionals and engineers determine the cooling capacity needed for equipment spaces.
The calculator uses the formula:
Where:
Explanation: The sensible cooling load is multiplied by a latent factor to account for moisture removal requirements.
Details: Accurate cooling load estimation ensures proper equipment sizing, energy efficiency, and reliable operation of cooling systems.
Tips: Enter the sensible cooling load in Watts and the latent factor (default 1.25). All values must be > 0.
Q1: What is sensible cooling load?
A: Sensible cooling load is the heat added or removed from conditioned space through surfaces and by equipment operation.
Q2: Why is there a ±5% on the latent factor?
A: The ±5% accounts for variations in humidity levels and equipment efficiency.
Q3: When would I change the latent factor?
A: Adjust for different humidity conditions (higher for humid climates, lower for dry climates).
Q4: How do I find the sensible cooling load?
A: Use equipment specifications or calculate from heat generation rates and surface areas.
Q5: Does this include safety factors?
A: No, consider adding 10-20% to the calculated load for design safety margins.
