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

- Sensible Heat Ratio
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. SHR = sensible heat ratio (ratio of sensible heat load to total heat load) q s = sensible heat load (kW, Btu/hr)
What is sensible heat? Sensible heat refers to heat you can feel, or sense. This is any heat which can be measured on a thermometer, whether it’s heat from the sun shining on a sunny day, or the flame from a candle. When an object is heated, the object’s increase in temperature is sensible heat.
14 paź 2017 · The main difference between latent heat and sensible heat is that latent heat is defined for a system that undergoes a phase change of matter whereas the sensible heat is defined for a system that has no change in the phase of matter.
26 mar 2024 · Sensible heat ratio (SHR) is the ratio between the sensible heat and the total heat. SHR is expressed in percentage and it is calculated by dividing the sensible heat by the total heat. SHR 80% means the sensible heat is 80% of the total heat while the other 20% is latent heat.

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
