Total Solar Energy Rejected Definition

The shgc or its counterpart the total solar energy rejected tser reflects the true performance of solar heat gain or rejection through a window int o a building and its calculation includes ir rejection.

Total solar energy rejected definition.

The total amount of visible light that is transmitted through the window film glass. When a number is presented to describe tser the higher the number is the greater the amount of total solar energy i e. Total solar absorbance the amount of heat and light absorbed by the window film. Visible light transmission.

All film products indeed all glazing systems have improved total solar energy rejection as the sun climbs higher in the sky and sunlight strikes a vertical glass window less directly. However because of the technologies that we currently use to consume fuels a lot of it gets tossed out by turning it into heat in the environment which is totally useless. The higher the number the more visible light is being. The total solar energy tser specification along with another specification that is commonly used in the glass.

Clearly then when we read the specification called total solar energy rejection we can now see that it is not referring to temperature reduction percentage but rather it is the percentage of incident solar energy rejected. Total solar energy rejected tser on angle is not recognized by them as a measure of performance. Rejected energy is part of the energy of a fuel such as gas or petrol that could be used for a purposeful activity like making electricity or transport. The lower the number the less visible light is being transmitted darker.

Therefore total solar energy rejected is a factor that is used to determine the total amount of solar energy that is not able to pass through the glass. Total solar energy rejected. Heat that is rejected. When the sun is directly overhead all vertical windows.

The ir rejection rate is a number that lets customer understand that the film can reject majority of the heat from infrared it does not mean that if a large portion of the ir is blocked. Total solar reflectance the amount of heat and light absorbed by the window film. Separating the ir rejection for purposes of reporting heat gain is misleading. Let us help you understand some of these common terms better.

55 lets go through these few specifications that are most common in all window film one by one so that consumers can understand better. Total solar reflectance the ratio of total solar energy which is reflected outward. Total solar transmittance the ratio of the amount of total solar energy in the full solar wavelength range 300 2 100 nanometers that is allowed to pass through a glazing system to the amount of total solar energy falling on that glazing system value is usually expressed as a percent. Total solar energy rejected the amount of heat and light rejected by the window film.
