[0002] In daily life, people spend a large part of their time indoors, and the comfort of the indoor environment will have different degrees of impact on people's lives and work. The indoor thermal environment is the main factor affecting comfort, and its related parameters include temperature, humidity, wind speed, and average radiant temperature. In addition, indoor air pollutants can also have an important impact on human health, such as common carbon dioxide, formaldehyde, toluene, TVOC, etc. Among them, the HVAC system that creates the indoor environment is the main source of carbon emissions and energy consumption in the construction industry. Existing industry technical survey reports show that the energy consumption of HVAC systems varies from 40% to 50% in different buildings, accounting for more than 20% of the total energy consumption. The HVAC system consumes a lot of energy, and thus emits a large amount of carbon dioxide.

[0003] At present, the problem of balancing the energy consumption of air-conditioning units and indoor comfort has not been fully solved, because when optimizing one parameter, the other parameter will also be affected. Therefore, finding the balance point between the energy consumption of air-conditioning units and indoor comfort through reasonable air-conditioning system layout and structural optimization is a technical difficulty in improving air-conditioning systems, and it is also a problem that needs to be solved urgently.

[0024] like Figure 1 As shown, an embodiment of the present application provides a fresh air air conditioning system, which is arranged above a predetermined space. The predetermined space can be a small space such as a room or a living room, or a large-span space such as a shopping mall or a supermarket. It includes a fresh air unit 100, two fan coil units 200, a processor 300 and a camera 400.

[0025] The fresh air unit 100 includes a fresh air fan 110 and a fresh air pipeline 120 connected to the fresh air fan 110 , and a plurality of first air supply ports 121 are formed on the fresh air pipeline 120 .

[0026] The fan coil unit 200 includes a fan coil 210 and a ventilation duct 220 connected thereto, wherein the ventilation duct 220 is spaced apart along the length direction of the fresh air duct 120, and a plurality of second air supply ports 221 are formed on the ventilation duct 220, and a return air port 211 is formed on the fan coil 210;

[0027] The fan coil unit 210 and the fresh air fan 110 both include an air duct 101 and a heat exchange coil unit 102 . An air valve 103 is provided in the air duct 101 , and a water valve 104 is provided on the heat exchange coil unit 102 .

[0028] It can be understood that the opening and closing of the air valve 103 is used to control whether the air duct can supply air. When it is opened, the air duct 101 is opened to supply air. When it is closed, the air duct 101 is closed to stop supplying air. Correspondingly, the opening size of the air valve 103 can effectively control the amount of air supplied.

[0029] Part of the heat exchange coil 102 is located inside the air duct 101. Hot water or cooling liquid flows in the heat exchange coil 102, and heat is exchanged with the air inside the air duct 101 through the tube wall to realize the transmission of hot air or cold air, wherein the opening and closing of the air valve 103 directly determines the corresponding amount of heat.

[0030] The predetermined space is divided into a number of large space partitions 5, each of which is provided with a fan coil unit 200, and a camera 400 is provided above each large space partition for monitoring the number of people in the corresponding large space partition.

[0031] The processor 300 is electrically connected to the air valve 103, the water valve 104, the fresh air fan 110, the fan coil unit 210, and the camera, and is used to control the operation of the air valve 103, the water valve 104, the fresh air fan 110, and the fan coil unit 210 according to the number of people photographed by the camera 400.

[0032] It can be understood that the processor 300 can be used in an automatic or manual manner. When the manual mode is used, different air supply modes are pre-set inside the processor. The staff sets different air supply modes for different large space partitions 5 according to the number of people inside different large space partitions. For example, if there are more people in the first large space partition, the water valve and the air valve can be adjusted to a larger opening mode, thereby forming a stronger cold air or hot air delivery. If there are fewer or no people in the second large space partition, the water valve and the air valve can be adjusted to a smaller opening or closed mode.

[0033] When the automatic mode is adopted, software can be pre-written inside the processor 300. The software controls the water valve and the air valve according to the number of people, and can control the working power of the fresh air fan 110 and the fan coil unit 210.

[0034] Preferably, the camera 400 is located in the middle area corresponding to the upper part of the large space partition 5 .

[0035] More preferably, in order to ensure that the output air temperature is appropriate, the ventilation duct 220 is provided with a temperature sensor 500 near the fan coil 210, and the temperature sensor 500 is electrically connected to the processor 300. The processor 300 controls the operation of the air valve 103, the water valve 104, the fresh air fan 110, and the fan coil 210 according to the temperature feedback from the temperature sensor.

[0036] The fresh air duct 120 is arranged to pass through the two large space partitions 5 , and the ventilation duct 220 is arranged vertically to the fresh air duct 120 .

[0037] The processor 300 is configured to adjust the air valve 103 first and then adjust the water valve 104. Since the supply air temperature is affected by the air volume and water flow of the fan coil 210 and the fresh air unit 100 at the same time, when adjusting the water valve 104 and the air valve 103, the air valve 103 can be adjusted first according to the pre-set or calculated air volume. After the air volume stabilizes, the water flow becomes the only variable affecting the supply air temperature. The required supply air temperature can be obtained by adjusting the water valve 104.

[0038] The fresh air air conditioning system provided in the present application, through the reasonable arrangement of the fresh air unit 100 and the fan coil unit 200, controls the opening and closing of the air valve 103 and the water valve 104 based on the number of people, and then performs zoned air supply to different large space partitions, so as to specifically improve the comfort and hygiene of the local environment, and ensure that the energy consumption of the air conditioning system and the environmental thermal comfort are balanced as much as possible.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
