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
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 ...
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.
3 cze 2019 · Heat rises and so the air conditioning unit inside the room is either ceiling-suspended or wall mounted. However, this unit will only ‘push’ cool air into the room. Inside a server rack, there could be a build-up of heat referred to as ‘hot-spots’.
How to Calculate Heat Load in Electrical/Electronic Panel Enclosure. by Editorial Staff. Total heat load consists of the heat transfer from outside your panel and from the heat dissipated inside the control unit. Useful terms & Conversions:
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.
