There is no heating in winter in Guangdong. In the humid south, in addition to heat radiation that can take away the heat from the pipes, more heat is lost through heat conduction. Moist air is an excellent conductor of heat, and they transfer heat away from pipes at a much faster rate than dry air. In addition, moist air has a much larger heat capacity than dry air, and the heat they absorb cannot be significantly reflected in raising their own temperature. Therefore, heating cannot be installed in the southern region where Guangdong is located, which not only consumes a lot of energy, but also has high renovation costs, and its effect is not as good as in the north.

Then, it is best to add a box that can control temperature changes~
3. Environmental reliability test: HD-E702 constant temperature and humidity test chamber
