Heating and cooling load calculations are carried out to estimate the required capacity of heating and cooling systems, which can maintain the required conditions in the conditioned space. To estimate the required cooling or heating capacities, one has to have information regarding the design indoor and outdoor conditions, specifications of the building, specifications of the conditioned space (such as the occupancy, activity level, various appliances and equipment used etc.) and any special requirements of the particular application.

HVAC Cooling Load Estimation Excel Sheets:

When we talk about sizing an air conditioning appliance (tons of cooling, BTU/h or KW), we are specifying the cooling capacity (power) that needs to be moved by the appliance (air conditioner) from the indoor space to outdoors. The actual electrical power used to operate the appliance is considerably less than the cooling power it needs to move.


In these excel file you will find a collection of calculation excel sheets for HVAC Design, cooling and heating load estimation, it facilitates the process of calculation and saves time and efforts.
