The design cooling load (or heat gain) is the amount of heat energy to be removed from a house by the HVAC equipment to maintain the house at indoor design temperature when worst case outdoor design temperature is being experienced. There are two types of cooling loads: sensible cooling load; latent cooling load
The Sensible Heat Ratio - SHR - is used to describe the ratio of sensible heat load to total heat load and can be expressed as: SHR = q s / q t. = q s / (q s + q l ) (1) where.
Multiply the panel surface area times the BTU/hr. per square foot (or watts per square meter) to get the external heat transfer in BTU/hr or in watts. Sum the internal and external heat loads calculated.
Sensible Heat Gain – is the energy added to the space by conduction, convection and/or radiation. Latent Heat Gain – is the energy added to the space when moisture is added to the space by means of vapor emitted by the occupants, generated by a process or through air infiltration from outside or adjacent areas. Radiant Heat Gain
Sensible Heat. The sensible heat in a heating or cooling process of air (heating or cooling capacity) can be calculated in SI-units as. h s = c p ρ q dt (1) where . h s = sensible heat (kW) c p = specific heat of air (1.006 kJ/kg o C) ρ = density of air (1.202 kg/m 3) q = air volume flow (m 3 /s) dt = temperature difference (o C) Or in ...
10 kwi 2024 · For People, the “Sensible Radiant” is the fraction of heat released as long wave radiation that is absorbed by our surroundings and is radiated back out after a time delay as sensible load. The amount of Time Delay Sensible load for spaces is not able to be hand calculated.
26 gru 2017 · If you’re just cooling the products then you only need to consider the sensible heat load. If you’re freezing the product then you need to account for the latent heat also as a phase change occurs.
