Sensible Heat Load Calculator
The Sensible Heat Load Calculator is a valuable tool used in various industries to determine the amount of heat that needs to be added or removed from a space to achieve a desired temperature. It’s especially crucial in HVAC (Heating, Ventilation, and Air Conditioning) systems, aiding in designing efficient cooling or heating solutions.
Formula of Sensible Heat Load Calculator
Formula
Qs=m˙×Cp×ΔT
Where:
- Qs = Sensible heat load (in Watts or BTU/hr)
- ˙m˙ = Mass flow rate of the refrigerant (in kg/s or lb/hr)
- Cp = Specific heat capacity of the refrigerant (in J/kg°C or BTU/lb°F)
- ΔT = Temperature difference (in °C or °F)
This calculation assists in determining the necessary heating or cooling capacity required for a given space based on specific environmental conditions.

Example of Sensible Heat Load Calculator
Consider a scenario where an HVAC technician needs to determine the heat load for an office space. Given a mass flow rate of 1000 kg/hr, a specific heat capacity of 1.5 J/kg°C, and a temperature difference of 20°C, the sensible heat load can be calculated as follows:
Qs = 1000×1.5×20 = 30,000 Watts
This implies that a cooling or heating system with a capacity of 30,000 Watts would be require to maintain the desired temperature in the office space.
