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.
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
21 kwi 2022 · How to Calculate the Sensible Heat Transfer of Water. Example: 200 GPM water enters a coil at 120°F and leaves at 80°F. Step #1 – Determine the ∆T (120°F – 80°F = 40°F) Step #2 – Enter all values into equation. q = GPM x 500 x ∆T. q = 200 x 500 x 40 = 4,000,000 Btu/hour.
Sensible heat load and required air volume to keep the temperature constant at various temperature differences between make up air and room air: Sensible Heat Load and Required Air Volume Chart (pdf) . Latent Heat. Latent heat due to the moisture in air can be calculated in SI-units as: h l = ρ h we q dw kg (2) . where . h l = latent heat (kW) .
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.
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.
Sensible heat ratio (SHR) describes the ratio of sensible heat load to total heat load and is applied for cooling and air conditioning applications in buildings.
