This coefficient accounts for the time lag between the outdoor and indoor temperature peaks. Depending on the properties of the building envelope, a delay is present when observing the amount of heat being transferred inside from the outdoors. The CLF is the cooling load at a given time compared to the heat gain from earlier in the day. [1] [5]
Chlorine trifluoride is an interhalogen compound with the formula ClF 3.It is a colorless, poisonous, corrosive, and extremely reactive gas that condenses to a pale-greenish yellow liquid, the form in which it is most often sold (pressurized at room temperature).

Rocket fuel chemist John Drury Clark reported in his book Ignition! that chloryl fluoride "is indecently reactive, and the hardest to keep of all the CI-O-F compounds, since it apparently dissolves the protective metal fluoride coatings that make the storage of ClF 3 comparatively simple."
Carbonyl fluoride is usually produced as a decomposition product of fluorinated hydrocarbons in the thermal decomposition thereof, for example from trifluoromethanol or tetrafluoromethane in the presence of water:
