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 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) .
6 maj 2024 · To understand why the cooling capacity of air conditioners is made of two different types of cooling capacities, we need to understand what are sensible heat and latent heat. Sensible Heat. As the name suggests, sensible heat is the heat that we can feel or able to sense (sense-able). Conventionally, it is measured as temperature. The greater ...
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
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.
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 sensible heat is defined for a system that has no change in the phase of matter.
