Abstract

Vehicle thermal loads in sunny climates are strongly influenced by the absorption of solar thermal energy. Reduction of the absorptivity in the near infrared spectrum would decrease vehicle soak temperatures, reduce air conditioning power consumption and not affect the vehicle color (visible spectrum radiation properties). The literature [1] indicates that paint formulations with carbon-black pigment removed can be made to be reflective to the near infrared. Figure 1 demonstrates the spectral absorptivity changes attainable with this technique with Solar Reflective Black (SRB) paint free of carbon-black pigment
