| description | The invention discloses a system for realizing high-precision control of a low-temperature and low-humidity environment, which belongs to the technical field of heating ventilation air conditioner temperature and humidity energy-saving control, and comprises an air conditioning unit consisting of an AHU front section, a rotating wheel dehumidification section and an AHU rear section, a PLC (Programmable Logic Controller) in signal connection with the air conditioning unit, and a human-computer interface in signal connection with the PLC, the invention further discloses a method for achieving high-precision control of the low-temperature and low-humidity environment. According to the method, the regeneration heat set temperature of the rotary dehumidifier is dynamically adjusted, loading and unloading of surface cooling/heating/humidifying are pre-judged in advance, and on-off time is controlled through switching value electric heating according to the pulse width modulation (PWM) principle; the hysteresis qua |
