The invention relates to a device for measuring and controlling a
dew point temperature and an implementation method thereof. The device comprises a
master controller, a sensor module, a touch screen, a humidification module, a refrigerating
control circuit, a compressor, a heater and a
control circuit of the heater. The sensor module comprises a temperature and
humidity sensor and an A / D converter. The implementation method for measuring and controlling the
dew point temperature includes a method for measuring the
dew point temperature and an implementation method with the
dew point temperature as a control target. The implementation method for measuring and controlling the
dew point temperature includes the following steps of acquisition, calculation of the
dew point temperature, calculation of errors of the dew point temperature, calculation of output of a PI controller and calculation the action time of a
humidity execution mechanism. The device for measuring and controlling the dew point temperature and the implementation method thereof have the advantages that dew point
temperature measurement precision is high, and the problem that when a
humidity set value is the dew point temperature,
relative humidity needs to be converted into the dew point temperature, and accordingly
measurement precision is affected is solved.
