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 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 in a heating or cooling process of air (heating or cooling capacity) can be calculated in SI-units as. h s = cpρ q dt (1) where. h s = sensible heat (kW) cp= specific heat of air (1.006 kJ/kg oC) ρ = density of air (1.202 kg/m3) q = air volume flow (m3/s) dt = temperature difference (oC)
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.
A sensible heat ratio around 0.70 is commonly used in air-conditioning systems [2, 3]. This means that 70% capacity of the cooling coil is used in handling the sensible load and the remaining 30% cooling capacity takes care of the latent load.
15 mar 2022 · Abstract. Conventional air conditioning (AC) systems provide simultaneous sensible and latent cooling. This requires air to be cooled below its dew point temperature resulting in low energy efficiency, particularly at low sensible heat ratios where supply air might be reheated.
Sensible heat storage (SHS) is a method of storing thermal energy by heating a substance with a high heat capacity, such as water or rock, and holding it at an elevated temperature for later use.
