The specific embodiment
As shown in Figure 1, the present invention includes air conditioner 1, have fresh wind port 3, return air inlet 2 and air outlet 4 on air conditioner 1, fresh wind port 3, return air inlet 2, air outlet 4 connect respectively fresh air pipeline 6, return air duct 5 and air supply duct 7; Return air duct 5 is provided with air returning valve 8 and humiture receptor 10, fresh air pipeline 6 is provided with new air-valve 9, air conditioner 1 bottom is provided with hot and cold water return pipe 11, humidifier 12 and reheater 13, hot and cold water return pipe 11, humidifier 12 and reheater 13 are from left to right located at the rear of return air inlet 2 and fresh wind port 3 wind direction intersections successively, hot and cold water return pipe 11 is provided with Cold-hot water valve 14, and humidifier 12 is provided with humidifier valve 15, and reheater 16 is provided with thermal valve 13 again; Air outlet 4 rears are provided with pressure fan 18, and return air inlet 2 rears are provided with return fan 17, and pressure fan 18 is provided with frequency converter 20 and differential pressure sensor 22, and return fan 17 is provided with frequency converter 19 and differential pressure sensor 21; Air conditioner 1 outside is provided with PID controller, and described air returning valve 8, humiture receptor 10, new air-valve 9, Cold-hot water valve 14, humidifier valve 15, thermal valve 16, frequency converter 19,20, differential pressure sensor 21,22 are all connected with PID controller again.
The course of work of this example:
The temperature that humiture receptor in return air duct 5 10 is measured is decided to be return air temperature; The pressure that pressure fan 18 upward pressure receptors 22 are measured is decided to be blast pressure, and the pressure that return fan 17 upward pressure receptors 21 are measured is decided to be return air pressure:
(1) summer operation pattern:
According to the comparison of return air temperature and design temperature, by PID controller, regulate Cold-hot water valve 14 apertures to guarantee the infinite approach of return air temperature and design temperature.According to the comparison of return air temperature and design temperature, by PID controller, regulate again thermal valve 16 apertures to guarantee the infinite approach of return air temperature and design temperature.According to return air humidity and the comparison of setting humidity, by PID controller, regulate humidifier valve 15 apertures, to guarantee return air humidity and the infinite approach of setting humidity.
