[0026] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0030] In existing technology, the notice regarding strict implementation of air conditioning temperature control standards for public buildings clearly stipulates the start-up temperature, set temperature, and energy conservation and consumption reduction for central air conditioning. Currently, in settings such as hospitals and rehabilitation centers, after turning on central air conditioning, each department relies on manual education and personal energy-saving awareness to close doors and windows and adjust the temperature. This is ineffective and still leads to significant energy waste. New technical means are needed to reduce the impact of human factors. To address these issues, the following solutions are proposed.

[0031] Reference Figure 1 As shown in FIG, a central air conditioning energy-saving controller 100 of the present technical solution is used to be connected in series between the central air conditioning control module 200 and the switch box 300. This means that even if the switch box 300 is operated alone, the switch signal cannot be directly output to the central air conditioning control module 200. Figure 2 As shown, the central air conditioning energy-saving controller 100 includes a switch control board 110, a door and window sensor 120 and a temperature sensor 130. The switch control board 110 is connected in series between the central air conditioning control module 200 and the switch box 300 to control the on and off of the two. The signal output ends of the door and window sensor 120 and the temperature sensor 130 are electrically connected to the switch control board 110 to control the closing and opening of the output ends of the switch control board 110.

[0032] By connecting the central air-conditioning energy-saving controller 100 in series between the central air-conditioning control module 200 and the switch box 300, and using the door and window sensor 120 and the temperature sensor 130 to collect the indoor temperature and whether the doors and windows are closed, when the indoor temperature reaches the set temperature and the doors and windows are closed, the switch control board 110 controls the closure between the central air-conditioning control module 200 and the switch box 300. Only then can the user operate the switch box 300, thereby meeting the national requirements for air-conditioning temperature control standards for public buildings and satisfying the hospital's goal of energy saving and consumption reduction.

[0033] Furthermore, the door and window sensors 120 include at least one group of door magnetic control sensors and at least one group of window magnetic control sensors. The corresponding door and window sensors 120 can be set according to the specific number of doors and windows in the room. The door magnetic control sensors and window magnetic control sensors are both magnetic sensors, and only when the doors and windows are completely closed will they output a closing signal to the switch control board 110.

[0034] like Figure 3 As shown, the magnetic sensor includes a magnet 121 and a magneto-electric induction device 122. The magnet 121 and the magneto-electric induction device 122 of the door magnetic control sensor are respectively arranged on the door frame side and the door leaf side. When the door frame side and the door leaf side are completely closed, the magnet 121 and the magneto-electric induction device 122 are attracted, and the magneto-electric induction device 122 outputs a closing signal to the switch control board 110; the magnet 121 and the magneto-electric induction device 122 of the window magnetic control sensor are respectively arranged on the window frame side and the window leaf side. When the window frame side and the window leaf side are completely closed, the magnet 121 and the magneto-electric induction device 122 are attracted, and the magneto-electric induction device 122 outputs a closing signal to the switch control board 110.

[0035] like Figure 2As shown, the central air conditioning energy-saving controller 100 further includes a power supply module 140 , which supplies power to the switch control board 110 , the door and window sensor 120 , and the temperature sensor 130 , providing a DC12V operating voltage.

[0036] Furthermore, the power module 140 adopts a switching power supply or a battery pack, with the switching power supply being preferred, which directly draws power from the mains and converts AC220V into DC12V, thereby reducing the cost and replacement of batteries.

[0037] like Figure 2 As shown, the central air conditioning energy-saving controller 100 also includes a radiator 150, and the power module 140 is arranged on the radiator 150. Since the power module 140 is in a high-temperature state for a long time, by providing a radiator 150 with cooling fins and made of metal, the power module 140 can be cooled in time to ensure the service life of the central air conditioning energy-saving controller 100.

[0038] Specifically, the switch control board 110 includes a single-chip microcomputer 111 and a normally open relay 112. In this embodiment, the single-chip microcomputer 111 adopts a 32-bit microcontroller with model APM32F103C8T6, and the normally open relay 112 adopts a 20A relay with model JQC-T78-DC6V-A. The contact assembly of the normally open relay 112 is connected in series between the central air-conditioning control module 200 and the switch box 300 to control the on and off of the two. The signal output ends of the door and window sensor 120 and the temperature sensor 130 are electrically connected to the single-chip microcomputer 111 to output door and window closing signals and temperature signals. The output end of the single-chip microcomputer 111 is connected to the coil of the normally open relay 112 to control the closing and opening of the contact assembly of the normally open relay 112.

[0039] In addition, the switch control panel 110 further includes a function switch key 113 , which can select the door and window closing signal and the temperature signal to control the closing and opening of the contact assembly of the normally open relay 112 separately or simultaneously as needed.

[0040] Furthermore, the switch control panel 110 also includes a digital display screen 114, which is connected to the single-chip computer 111 to display the temperature, making it convenient for the user to grasp the set temperature and real-time temperature. The switch control panel 110 also includes a temperature adjustment key 115, which can adjust the specific set temperature according to actual needs.

[0041] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
