Background
When the air conditioning system is operated to heat, the evaporation temperature of the refrigerant is reduced with the reduction of the outdoor environment temperature, and when the evaporation temperature of the refrigerant is lower than 0 ℃, the surface of the outdoor heat exchanger is liable to frost. With the aggravation of frosting degree, the heating effect of the air conditioning system is also continuously reduced, and when the frosting of the air conditioning system is serious, the heating is required to be stopped, and the air conditioning system enters a comprehensive frosting working state. The conventional air conditioning system generally judges whether the chassis of the air conditioning system frosts or not through the temperature fed back by the temperature sensing components arranged around the chassis.
However, the applicant found that the problem of inaccurate judgment exists in judging whether the chassis of the air conditioning system is frosted or not through the temperature fed back by the temperature sensing assembly. Specifically, as a certain time is needed for frosting, when the temperature sensing assembly starts to monitor that the temperature is lower than 0 ℃, the air conditioning system starts to start the defrosting process, but the chassis may not have frosting at this time, and the defrosting process is started too early, so that energy waste is caused; similarly, as defrosting also needs a certain time, the defrosting process is started, the surface temperature of the outdoor heat exchanger is increased, when the temperature sensing assembly starts to monitor that the temperature is higher than 0 ℃, the air conditioning system stops the defrosting process, but at the moment, the chassis may still have unfused frost, and the defrosting process is stopped too early, so that the problem of incomplete defrosting is caused.

Preferably, the wind-driven sensing device 11 is slidably and rotatably arranged on the guide rail 12, and the wind-driven sensing device 11 reciprocates on the guide rail 12 under the driving of wind power. The reciprocating motion in this embodiment means that the wind-driven sensor 11 is driven by wind force to move from the first end 121 of the guide rail 12 to the second end 122 of the guide rail 12, then turn back, and move from the second end 122 of the guide rail 12 to the first end 121 of the guide rail 12, thus circulating as shown in fig. 1.
When the pneumatic induction mechanism of the embodiment is applied to an air conditioning system, a unit is started, the fan 70 rotates, the pneumatic induction device 11 can reciprocate on the guide rail 12 by wind power provided by the fan 70, and when the chassis 80 of the air conditioning system frosts, the pneumatic induction device 11 is frosted and cannot reciprocate on the guide rail 12, so that whether the chassis 80 frosts or not can be judged by judging the motion state of the pneumatic induction device 11. The pneumatic sensing mechanism of the embodiment is utilized to judge whether the chassis 80 frosts or not, so that the pneumatic sensing mechanism has the advantage of accurate judgment, and therefore, the start and stop of the defrosting mechanism 20 can be accurately controlled, the energy waste caused by the early start of the defrosting mechanism 20 can be avoided, and the incomplete defrosting caused by the early stop of the defrosting mechanism 20 can also be avoided.

The monitoring module monitors the position of the wind-driven sensing device 11, so that the movement state of the wind-driven sensing device 11 can be judged. Without being limited thereto, the movement state of the wind-driven induction device 11 may also be judged by whether the wind-driven induction device 11 is in contact with the first reversing device 13 and the second reversing device 14 for a preset period of time. Specifically, the monitoring module monitors the position of the pneumatic sensor 11 to change continuously, so as to indicate that the pneumatic sensor 11 is in a motion state; the monitoring module monitors that the position of the wind-driven sensing device 11 is unchanged, and indicates that the wind-driven sensing device 11 is in a static state.

Preferably, the upper surface of the bottom case 111 has a square structure, and the wind guard 112 is located at a diagonal line of the upper surface of the bottom case 111, as shown in fig. 2. The wind deflector 112 is not limited to this, and may be provided obliquely so as to intersect with the symmetry axis of the upper surface of the bottom case 111 (i.e., the wind deflector 112 is not parallel to the symmetry axis of the upper surface of the bottom case 111). In the wind-driven induction mechanism of the preferred technical scheme of the embodiment, the wind-driven induction device 11 comprises a bottom box 111, a wind shield 112 and a roller 113, and wind force acts on the wind shield 112, so that the wind shield 112 can be driven by wind force to drive the bottom box 111 and the roller 113 to move; in the second aspect, the wind acting direction intersects with the normal line of the wind guard 112, so that after the wind-driven sensing device 11 rotates, the wind acting direction on the wind guard 112 is opposite, and the wind-driven sensing device 11 can be driven to move in opposite directions; in the third aspect, the roller 113 is further rotatably disposed on the guide rail 12, so that when the wind-driven sensor 11 moves to contact with the first direction-changing device 13 or the second direction-changing device 14, the wind-driven sensor 11 can be rotated by the toggling action of the first direction-changing device 13 and the second direction-changing device 14.

The back and forth movement process of the wind-driven induction mechanism is described with reference to fig. 1 and 2: in the state of fig. 2, the arrow direction is the wind acting direction, and at this time, the back surface of the wind deflector 112 (the back surface refers to the back surface as shown in fig. 2) is acted on by wind force, so that the wind driven sensor 11 moves from the first end 121 to the second end 122 (i.e. from right to left) of the guide rail 12; when the wind-driven sensing device 11 moves to be in contact with the second reversing device 14, the poking rod of the second reversing device 14 is inserted into the opening 1111 on the left side of the bottom box 111, and the poking rod is rotated to enable the wind-driven sensing device 11 to rotate 90 degrees, at this time, the direction of the wind screen 112 changes, but the front surface (the front surface refers to the front surface as shown in fig. 2) of the wind screen 112 is subjected to the action of wind force due to the fact that the wind force direction is unchanged, namely, the wind force direction of the wind screen 112 is opposite, so that the wind force drives the wind-driven sensing device 11 to move from the second end 122 of the guide rail 12 to the first end 121 (namely, from left to right); likewise, when the wind-driven sensing device 11 moves to contact with the first reversing device 13, the wind-driven sensing device 11 can be rotated, and the wind direction of the wind-driven sensing device 11 is opposite; by this circulation, the reciprocating movement of the wind-driven sensor 11 on the guide rail 12 can be realized.
