You can easily calculate the SHR by dividing the sensible capacity by the total capacity and the latent is simply the sensible subtracted from the total.

“SHR” stands for “Sensible Heat Ratio” and it is a way to determine how much of the total capacity of an HVAC unit is used for sensible cooling versus latent cooling. meaning only 20% or 30% of the capacity of the unit is available for controlling latent heat.

Sensible heat is what registers on your thermostat. It reflects a temperature change. Technically speaking, sensible heat refers to the amount of energy needed to increase or decrease the temperature of some substance, independent of phase changes (like a gas-to-liquid phase change).

Sensible Heat Factor is the ratio of sensible heat to total heat and is represented as SHF = 1/(1+(LH/Qsensible)) or sensible_heat_factor = 1/(1+(Latent Heat/Sensible Heat)).

The inability of a coil to cool or heat the air to its temperature is indicated by a factor called by-pass factor (BPF) or Coil Bypass Factor. BPF can also be defined as the ratio of air which is unaffected by the coil to the total quantity of air passing over the coil. …

This line represents the psychrometric process of the supply air within the conditioned space and is called the room sensible heat factor line. The slope of the RSHF line illustrates the ratio of sensible to latent heat loads within the space and is illustrated in Fig. 37 by Δhs (sensible heat) and Δhl (latent heat).

The Sensible Heat Ratio (SHR) is the total sensible heat flow divided by the total heat flow (sensible + latent). Sensible heat flow causes temperature change in a substance, in this case air, without changing the moisture content of the air.

In sensible heating process the temperature of air is increased without changing its moisture content. During this process the sensible heat, DB and WB temperature of the air increases while latent of air, and the DP point temperature of the air remains constant.

Psychrometric charts are complex graphs that can be used to assess the physical and thermodynamic properties of gas-vapour mixtures at a constant pressure. They are often used to assess the properties of moist air.

The initial and final points on the psychrometric chart give all the properties of the air.  Sensible Heating of the Air Sensible heating process is opposite to sensible cooling process. In sensible heating process the temperature of air is increased without changing its moisture content.

A Psychrometric Chart is an important tool for HVAC engineers to carry out heat load or cooling load calculations and find solutions to various air condition related problems. Psychrometric charts are graphic representations of the psychrometric properties of air.

The process in which the moisture or water vapor or humidity is added to the air without changing its dry bulb (DB) temperature is called as humidification process. Humidification process along with cooling or heating is used in number of air conditioning applications.

Atomise: break a liquid up into many very fine droplets so as to increase the contact surface with the air, thus assisting evaporation. Condensation: change from the gaseous state of water (vapour) to the liquid state. Condensation occurs when hot and humid air is cooled, losing its capacity to hold water vapour.

The dehumidification process is the inverse of adding water to the room with an evaporative cooler, and instead releases heat. Therefore, an in-room dehumidifier will always warm the room and reduce the relative humidity indirectly, as well as reducing the humidity more directly, by condensing and removing water.

If you dehumidify air with a refrigeration type dehumidifier within the space, there will be a temperature rise from the condenser side of the dehumidifier.

Here are the best dehumidifiers currently on the market.

1. Meaco 20l low energy refrigerant dehumidifier.
2. EcoAir DD322 classic desiccant dehumidifier.
3. Duronic DH05 mini dehumidifier.
4. EcoAir DD1 MK5 classic desiccant dehumidifier.
5. Ebac 3850e 21 litre refrigerant dehumidifier.

Dehumidifiers remove moisture from the air. This curbs the growth of mold and dust mites. They are particularly useful in parts of the house where humidity collects like damp basements. Dehumidifiers draw air over cold coils, condensing out its moisture, before passing the air over warm coils and back into the room.

Dehumidifiers work to remove moisture from the air, creating a dryer environment which is more difficult for creepy-crawlies to survive in. No bugs are nice to see, but the ones that crave moisture are the ones you really hope to avoid on your way to the bathroom.

Can I leave the dehumidifier running at night? Yes, we recommend using a dehumidifier 24hrs, however be aware that there will always be a noise generated from the machine when it is operating. Otherwise we suggest using the dehumidifier from early morning until late evening and then turn the machine off.
