The application discloses a
dew point
temperature control system of a light composite environment
simulation test box, and belongs to the technical field of
extreme climate light composite environment
simulation test. In view of the problem that the existing light environment
simulation test box cannot be compatible with low-temperature and high-temperature and high-
humidity extreme climate environment
simulation test due to condensation of light glass, the
dew point
temperature control system of the light composite environment
simulation test box is automatically controlled by using light-transmitting double-layer glass devices and
software, the temperature of the interlayer glass is automatically adjusted by the
control system according to a
test program, the temperature of the interlayer glass is always higher than the
dew point temperature corresponding to the temperature and
humidity in the
test chamber, the condensation phenomenon of the light glass is fundamentally avoided, the composite light environment
simulation test of the test box under the
extreme climate of low temperature-50 DEG C, high temperature 125 DEG C and
humidity 20%-95% is realized, the accuracy of test results is ensured, and the test standard requirements are met.
