Based on the damper assemblies of above-mentioned aspect embodiment, air door group according to an embodiment of the present invention is described below according to attached drawing The control method of part.In an embodiment of the present invention, damper assemblies include shell, air door and electromagnetic driver, wherein in shell Air duct is defined, shell is equipped with air outlet and air inlet, and air door is for be turned on or off air inlet and air outlet, electromagnetic drive Part connection air door simultaneously drives air door to switch between opening state and closed state position.

Fig. 4 is the flow chart of the control method of damper assemblies according to an embodiment of the present invention, as shown in figure 4, the present invention is real The control method for applying the damper assemblies of example includes:

S1 acquires the Current Temperatures of target position.

In embodiment, target position may include the air outlet of air door or the compartment of air outlet connection, pass through setting Temperature sensor in target position carries out temperature acquisition, and the Current Temperatures of target position are transmitted to control device.

S2 obtains the current state of air door.

Specifically, it can determine that air door is presently at opening state or closed state according to the switching signal of air door, And the current state of air door is transmitted to control device.

S3 controls electromagnetic driver according to the Current Temperatures of target position, the current state of air door and switch temperature threshold value Movement is to drive air door to dbjective state.Wherein, switch temperature threshold value can be set as the case may be.

In embodiment, electromagnetic driver, which can execute, starts work, pass movement or stopping movement, wherein starting work can To be interpreted as the movement that driving air door is opened, such as shown in Fig. 2, control electromagnetic coil forward direction is powered to generate positive magnetic field, just Repulsive force is generated to magnetic field and magnetic part to drive air door to open；Pass movement can be understood as the movement that driving air door is closed, example As shown in Fig. 2, control electromagnetic coil is reversely powered to generate opposing magnetic field, opposing magnetic field generates attraction with magnetic part to drive Air door is closed.

Specifically, when air door is in close state, if Current Temperatures are more than opening temperature threshold value, then it is assumed that air side Temperature is higher, needs to open air door and provides cold wind, then controls electromagnetic driver driving air door and open；It is beaten conversely, being in air door When open state, if Current Temperatures are lower than closing temperature threshold value, then it is assumed that air side temperature is lower, then controls electromagnetic driver drive Dynamic air door is closed, to reduce cooling capacity offer.For example, can be realized by controlling the energization direction of the electromagnetic coil of electromagnetic driver The driving that air door is opened or closed.

S4, according to the dbjective state of air door every the control electromagnetic driver movement of the first preset time to drive air door at least It makes a round trip.In other words, after driving air door to target position, per driving air door Reciprocative switch primary again at regular intervals or Repeatedly, and finally dbjective state is still returned back to, to meet current air-supply demand.

The electromagnetism part of electromagnetic driver has heating effect when driving and being powered, and controls air door every the first preset time It moves back and forth, the temperature difference of air door two sides can be made to reduce by frequent repeatedly movement, can effectively evade icing, even if having Faint ice sheet can also guarantee that system operation is normal.

By taking air door makes a round trip as an example, specifically, if air door is in the open state, controlled every the first preset time Electromagnetic driver executes pass movement and starts work to drive air door to close and control electromagnetic driver execution after the second preset time To drive air door to open, wherein the second preset time is less than the first preset time；Alternatively, if air door is in close state, Work is started every the control electromagnetic driver execution of the first preset time to drive air door to open and control after the second preset time Electromagnetic driver processed executes pass movement to drive air door to close, and the primary reciprocal driving of air door can be realized.It is of course also possible to drive Dynamic air door carries out the repeatedly above reciprocating motion, and type frequently reciprocating can reduce air door temperature difference, and meet air side Cold wind demand.

As an example, electromagnetic driver includes electromagnetic coil and magnetic part such as permanent magnet, electromagnetism referring to shown in Fig. 2 and 3 Coil energization direction is different, and then the effect between permanent magnet is attraction or repulsive force to the direction difference in the magnetic field of generation, from And it pulls or air door is pushed to close or open.Fig. 5 is the first preset time of air door interval according to an embodiment of the invention The flow chart of a reciprocating action is carried out, as shown in figure 5, specifically including:
