Total heat due to both temperature that is sensible heat and moisture that is latent heat. In a chilled-water system the air conditioner cools water down to 4 – 7oC. The chilled water is distributed throughout the building in a piping system and connected to air condition cooling units wherever needed. Read more linktext

SEER is the abbreviation of Seasonal Energy Efficiency Rating. That is given to air conditioners as an efficiency rating. So what is air conditioner SEER ratings and what they mean in terms of energy efficiency? In order to reduce wasted energy, the U.S. Department of Energy has established SEER ratings for air conditioners.The higher the number, the more efficient the unit and the less it will cost to provide cooling.

The term “size” to air conditioners is its ability to produce cooled air rather than the air conditioners’s physical dimensions. How room-size and whole-house air conditioners are measured? Both of them are manufactured in a variety of capacities, through these capacities we can measure their size. Read more linktext

In HVAC systems the efficient of heat exchangers is crucial .If the he efficient of heat exchangers is low the whole system will work at a low efficient. The heat exchangers will transferr lower – less heat than excepted if there is air in the steam.Today lat us discuss daltons law of partial Pressure and partial pressure in a mixture.
