6 FAQs about [Energy storage heat dissipation and refrigeration calculation]

How do you calculate latent and sensible cooling and heating equations?

The sensible heat in a heating or cooling process of air (heating or cooling capacity) can be calculated using the following equation: h s = cp ρ q dt (1) where h s = sensible heat (kW), cp = specific heat of air (1.006 kJ/kg°C), ρ = density of air (1.202 kg/m3), and q = air volume flow (m3/s).

How do you calculate sensible heat in a heating or cooling process?

The sensible heat in a heating or cooling process of air (heating or cooling capacity) can be calculated as h s = cp ρ q dt, where h s = sensible heat (kW), cp = specific heat of air (1.006 kJ/kg oC), ρ = density of air (1.202 kg/m3), q = air volume flow (m3/s), and dt = temperature difference (oC).

What is heat load in refrigerated space?

The intent of this course is to provide the background knowledge required to calculate the heat load of a refrigerated space (typically between 400F to -400F). It will break the heat load into four components: Transmission Load –sensible heat gain through the floor, walls and roof from the temperature difference across these surfaces.

What is the difference between space cooling load and space heat extraction rate?

Space Cooling Load – is the rate at which energy must be removed from a space to maintain a constant space air temperature. Space Heat Extraction Rate - the rate at which heat is removed from the conditioned space and is equal to the space cooling load if the room temperature remains constant.

How is energy stored as sensible heat in a material?
