The specific embodiment
As shown in Figure 1, the present invention relates to a kind of new blower fan unit automatic control system, comprise new blower fan group, DDC controller, central control computer and alarm.Wherein, new blower fan group is connected with DDC controller, and DDC controller is connected 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, after screen pack 5, be provided with water coil 6, 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, at air supply port 4 places, be also provided with a humiture receptor 16, this humiture receptor 16 is responsible for gathering air-supply humiture.Humiture receptor 10 is all connected with 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 are all connected with DDC controller.
The air enthalpy that DDC controller calculates according to outdoor temperature humidity receptor 10, thus by the valve actuator 11 of controlling on new air door 2, regulate resh air requirement, realize the energy-saving run of the annual operating mode of annual air-conditioning box.DDC controller is also according to air supply port 4 humiture receptors 16 and setting value, by controlling the valve actuator 13 on the electronic two-way control valve 9 of water coil 6 and humidification valve 4, regulate the aperture of electronic two-way control valve 9 and the switch of humidification valve 4, maintain air-supply humiture in setting range.
