The specific embodiment
As shown in Figure 1, the utility model relates to a kind of new blower fan unit automatic control system, comprises new blower fan group, DDC controller, central control computer and alarm.Wherein, new blower fan group links to each other with the DDC controller, and the DDC controller links to each other with alarm with central control computer.
As shown in Figure 2, new blower fan group comprises rack 1, rack 1 bottom rear is provided with new air door 2, two bottom sides is provided with return air door 3, and the place ahead, top is provided with air supply port 4, and new air door 2, return air door 3 wind direction intersections are provided with screen pack 5, be provided with water coil 6 behind the screen pack 5, water coil 6 tops are provided with humidification system, and humidification system top is provided with pressure fan 8, and pressure fan 8 air ports are towards air supply port 4; Water coil 6 is provided with electronic two-way control valve 9, and humidification system is provided with humidification valve 7.
In order to realize the monitoring to outdoor air conditions, outside new blower fan group air conditioning chamber, be provided with a humiture receptor 10, this humiture receptor 10 gathers the humiture of outdoor air, can calculate according to Hygrothermograph the enthalpy of air simultaneously.In order to realize the monitoring to wind pushing temperature, also be provided with a humiture receptor 16 at air supply port 4 places, this humiture receptor 16 is responsible for gathering the air-supply humiture.Humiture receptor 10 all links to each other with the DDC controller with humiture receptor 16.
In addition, corresponding valve actuator 11, valve actuator 15, the valve actuator 13 of being provided with on new air door 2, electronic two-way control valve 9 and humidification valve 4, valve actuator 11, valve actuator 15, valve actuator 13 all link to each other with the DDC controller.
