The heating device is to control the key link of the temperature and humidity test machine; The output voltage will be output to the relay, about 3-12 volt DC electricity adds on the solid state relay; its AC end is equivalent to the wire connection; Bring the heat into the box to heat the constant temperature and humidity machine, the temperature is about to reach your setting value; the controller is adjusted by adding it to the solid -state relay; Heat; this is temperature control above 89 degrees, how to control the temperature stability of temperature below 89 degrees? The constant temperature and humidity machine is how much the heat of heating through the solid relay; the cooling circulation of the compressor is also achieved by dynamic balance; the temperature is constant.

Treatment is an important part of the constant temperature constant humidity test machine, and it is important to determine the performance of a constant temperature and humidity test machine. Parameters include: compressor, condenser, running device, and evaporator. The compressor is the heart Cold system heart. It inhale low temperature and low pressure gas and turns into high temperature and high -pressure gases. It is used to release heat through condensation into liquid and take away heat through a fan. Therefore To the low -voltage liquid, the evaporator is second, and it becomes a low -temperature and low pressure gas, and returns to the compressor; the refrigerant absorbs the heat in the evaporator to complete the heavy gasification process and absorb heat, achieve the purposes of refrigeration, and complete the cooling process of the constant temperature and humidity machine.

The humidification system is also completed by the refrigeration system, the evaporator is placed in the constant temperature and humidity test machine; High moisture gases in the constant temperature and humidity machine are condensed into liquids with cold wet gases; such repeated high -humidity of the box will be very small, achieving the purpose of moisture reduction
