This advanced technology can not only achieve efficient energy saving and environmental protection of central air-conditioning, but also improve the comfort and safety of buildings.

[0029] Wherein: it also includes an impeller 8, a chiller 11 and an air cooler 12, the impeller 8 is arranged in the middle of the ventilation duct 7, the chiller 11 is placed on the right side of the rear end of the shell 1, the liquid inlet of the coil is connected with the liquid outlet of the chiller 11, the liquid outlet of the coil is connected with the liquid inlet of the chiller 11, the air cooler 12 is placed on the left side of the rear end of the shell 1, the chiller 11 is connected with the air cooler 12 through a conveying pipe, the input ends of the impeller 8, the chiller 11 and the air cooler 12 are electrically connected to the output end of the controller in the external control room, the surface cooler 9, the chiller 11 and the air cooler 12 are installed in coordination, the air outlet can quickly and evenly perform exhaust work, and can make the room temperature reach a suitable state in the shortest time, the sensor will work with the operation of the central air conditioner, avoiding the waste of electricity caused by the idle operation of the sensor.

[0030] The working principle of the energy-saving building cooling and heating control system provided by the utility model is as follows: when the building cooling and heating control system is used to assist the central air conditioner, the operator controls the chiller 11 to work through the controller in the external control room. The chiller 11 compresses the refrigerant, cools the refrigerant through the capillary tube, and then sends it to the criss-crossed coils in the surface cooler 9 through the connecting pipe. The controller in the external control room controls the impeller 8 to work, and the impeller 8 sucks the indoor hot air from the air inlet grille 10. When the hot air passes through the surface cooler 9, the refrigerant in the coil absorbs heat and cools the hot air. At this time, the refrigerant absorbs heat and the temperature becomes high, and returns to the inside of the chiller 11 again, and then is sent to the inside of the air cooler 12 through the delivery pipe. The air cooler 1 2 The refrigerant temperature is lowered and then sent back to the chiller 11 for recirculation. At the same time, the air cooled by the surface cooler 9 is sent into the shell 1 along the ventilation duct 7 by the impeller 8. At this time, the controller in the external control room controls the motor 593 to operate, and the output shaft of the motor 593 drives the bidirectional screw 591 to rotate, and the two sliders 592 move outward synchronously, forcing the connecting plate 54 to move outward, driving the rack plate 1 53 to move outward synchronously. Because the gear 1 52 is meshed and connected with the vertically corresponding rack plate 1 53, the angle of the upper blade 51 is deflected as the rack plate 1 53 moves, and the deflection angles of the front and rear upper blades 51 are opposite, so that the front and rear sides are exhausted synchronously. At the same time, as the rack As the plate 1 53 moves outward, the limiting plate 56 also moves outward synchronously. When the limiting notch 57 passes the outer end of the rack plate 2 583, the outer end of the rack plate 2 583 is not subjected to force, and the spring 1 586 expands without force, driving the rack plate 2 583 to move outward. Because the gear 2 582 is meshed and connected with the vertically adjacent rack plate 2 583, the angle of the lower blade 581 is deflected as the rack plate 2 583 moves, and the deflection angles of the left and right lower blades 581 are opposite. At this time, the front, back, left and right are all exhausted synchronously, and the exhaust is more uniform, which can quickly reduce the room temperature to a suitable temperature. At the same time, when the impeller 8 sends air into the interior of the housing 1, the air first passes through the wind blocking plate 61, and the air flow is large. Part of the air passes through the ventilation holes, while part of the air cannot pass through the ventilation holes in time, which continuously presses the air blocking plate 61, causing the air blocking plate 61 to move downward, and the spring 2 63 is compressed by the force, and the contact 65 moves downward synchronously until the contact 65 is close to the contact sheet 64. At this time, the temperature sensor 66 is energized to collect indoor data, and the indoor data is converted into an electrical signal and sent to the external controller. The external controller adjusts the equipment according to the data. When the air conditioner stops running, the impeller 8 stops delivering air, the air blocking plate 61 is not compressed by the airflow, and the spring 2 63 is not expanded by the force, driving the air blocking plate 61 back to its original position, and the contact 65 leaves the contact sheet 64, and the temperature sensor 66 is powered off, thereby avoiding the waste of electricity caused by the idle operation of the sensor.

[0031] It is worth noting that the motor 593 disclosed in the above embodiment is a DC4GN25-24 motor, the temperature sensor 66 is a QAA2061 temperature sensor, the impeller 8 is a WDF impeller, the surface cooler 9 is an HM-9377 surface cooler, the chiller 11 is a BSL-200WSE chiller, and the air cooler 12 is a KEF-470 air cooler. The controller in the external control room controls the operation of the motor 593, the temperature sensor 66, the impeller 8, the chiller 11 and the air cooler 12 using methods commonly used in the prior art.
