WebThe CLF is the cooling load at a given time compared to the heat gain from earlier in the day. The SC, or shading coefficient, is used widely in the evaluation of heat gain through glass and windows. Finally, the SCL, or solar cooling load factor, accounts for the variables associated with solar heat load. WebChlorine monofluoride is a volatile interhalogen compound with the chemical formula ClF. It is a colourless gas at room temperature and is stable even at high temperatures. When cooled to −100 °C, ClF condenses as a pale yellow liquid. Many of its properties are intermediate between its parent halogens, Cl 2 and F 2.
