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
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.
19 sie 2020 · Sensible Heat is the heat you see on the thermometer or thermostat. Latent Heat is the heat available in the air for phase changing. A phase change is considered to be the moment the ‘liquid in the air’ gets transformed, also known as vapor.
In cooling calculations, the common practice is to obtain the total rate of heat removal using Eq. 6.1, calculate the rate of sensible heat removal using Eq. 6.7 or SI equivalent and then obtain the sensible heat ratio (SHR), which is a useful parameter in cooling load calculations.
29 lip 2017 · When air is cooled or heated, the heating or cooling of the air is called sensible heating, and heating or cooling of water vapor in the air is called latent heating. The cooling process takes place at the evaporator (cooling coil), which is inside the air
