Usually expressed in Total BTU/hr or Tons of refrigeration. Total Heating Load: Expressed in BTU/hr.

Input exact wattage multiplied by 3.412 to convert Watts to BTU/hr. Step 4: Calculate Ventilation and Infiltration hvac calculation excel sheet 2021

For hydronic systems like chilled water, hot water, and condenser water loops, precise pipe sizing is critical to minimize pumping power and ensure proper flow. Usually expressed in Total BTU/hr or Tons of refrigeration

Misidentifying a West-facing window as an East-facing window shifts the peak cooling load hour, causing sizing errors. Step 4: Calculate Ventilation and Infiltration For hydronic

While an is incredibly powerful, users must keep certain limitations in mind to avoid errors:

Changing a single variable—such as upgrading from single-pane to double-pane windows—instantly updates the entire cooling and heating load requirements.
