Description

A new type of fresh air exchange system Technical Field

[0001] This utility model relates to a novel fresh air exchange system. Background Technology

[0002] The structure of a traditional fresh air exchange system is shown in Figure 1. It uses a high-power fan 1a to deliver fresh air to different areas of the room through the first duct 1b. A valve at the end of the duct controls the airflow. Simultaneously, a second duct 1c and another high-power fan 1d exhaust stale air from the room to the outside. The disadvantages of traditional fresh air exchange systems are: 1) Traditional systems use volute fans to deliver or draw air at the front end of the duct. Air travels a long distance through the duct, resulting in significant airflow loss and low system energy efficiency; 2) Traditional fresh air exchange systems use large fans, leading to high costs; 3) Traditional exhaust and fresh air exchange systems cannot provide differentiated airflow management at each outlet. People in different locations cannot set different fan speeds according to their needs; valves are used at each outlet to control airflow, resulting in wasted air; 4) Traditional exhaust and fresh air exchange systems cannot be programmed with differentiated automatic sensing functions for individual passengers, thus reducing passenger experience.

[0003] Summary of the Invention

[0004] The purpose of this utility model is to provide a novel fresh air exchange system to solve the technical problems of existing fresh air exchange systems that use a volute fan to supply or draw air at the front end of the duct, resulting in severe air volume loss and low system energy efficiency due to long-distance duct transmission, as well as large size, high cost, and inability to achieve differentiated air supply.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A novel fresh air exchange system includes a fresh air intake system and an exhaust system. The fresh air intake system delivers fresh outdoor air into the room, and the exhaust system delivers stale indoor air to the outside. The system is characterized by: the fresh air intake system comprising an intake duct, an air conditioning device, and a first air supply duct; the intake duct having an inlet and an outlet connected to the air conditioning device; the intake duct including a pipe and a duct fan installed within the pipe; the outlet of the air conditioning device connected to the first air supply duct; and the first air supply duct having multiple outlet ducts at its end, with a small duct fan installed at the outlet of each outlet duct, the small duct fans blowing fresh air supplied by the air conditioning device into the room.

[0007] The aforementioned exhaust system includes an exhaust duct, with multiple suction ducts at the end of the exhaust duct. Small duct suction fans are installed inside the openings of each suction duct. The small duct suction fans draw in indoor stale air and then sequentially transport it to the outside through the exhaust duct. A duct exhaust fan is installed inside the front end of the exhaust duct.

[0008] The aforementioned new air exchange system also includes a central control system. A terminal control system is installed at the outlet of each of the aforementioned air ducts. The terminal control system controls the operation of the small duct air supply fan, and the central control system sends control commands to the terminal control system.

[0009] The aforementioned central control system controls the operation of the duct supply fan, air conditioning unit, small duct suction fan, and duct exhaust fan.

[0010] The aforementioned air conditioning unit includes a filter, a surface cooler, and a humidifier, all housed in a single enclosure.

[0011] The aforementioned central control system is also connected to several infrared / temperature sensing systems. These systems detect the status of users near the duct outlet and send the sensing signals to the central control system. The central control system then controls the operation of each small duct air supply fan based on the sensing signals.

[0012] The aforementioned user location status includes whether or not user awareness is present, temperature awareness, and sleep awareness.

[0013] The air delivery angle of the aforementioned small ducted air supply fans is adjustable.

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] 1. This utility model retains the traditional fresh air exchange function, but replaces the volute fan in the traditional fresh air exchange system with a small high-speed fan structure inside the duct, which reduces the size of the fresh air system equipment, saves room space, and reduces costs.

[0016] 2. The fresh air exchange system of this utility model eliminates the traditional fan. By installing small duct air supply fans at the air inlet and air outlet of the duct, a siphon effect is formed in the duct to generate negative pressure, reduce the air volume attenuation in the duct, and improve the air supply efficiency of the fan system.

[0017] 3. The fresh air exchange system of this utility model has an independent control unit at each terminal air outlet, which controls the fan of each air outlet respectively; at the same time, there is also a centralized control system in the central control panel, which can control the speed of the fan at each terminal air outlet differently.

[0018] 4. The fresh air exchange system of this utility model is equipped with a small fan system at the end of each air outlet. People in different rooms can set different fan speeds according to their individual needs, which better meets the differentiated needs of the rooms and improves the experience of the people.

[0019] 5. The present invention provides a fresh air exchange system by adding an infrared / temperature sensing system at the end of each air outlet. This system can identify whether there are people in the room and whether they are sleeping. The system can also automatically adjust the optimal wind speed in different rooms through a centralized control system, thereby improving the overall efficiency of the fresh air exchange equipment and enhancing the comfort of people in the room.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Example 1:

[0026] As shown in Figures 2, 3, and 4, this embodiment provides a novel fresh air exchange system, including a fresh air intake system and an exhaust system. The fresh air intake system delivers fresh outdoor air into the room, and the exhaust system delivers stale indoor air to the outside. The system is characterized by: the fresh air intake system including an intake duct 1, an air conditioning device 2, and a first air supply duct 3; the intake duct 1 having an air inlet 11; the outlet of the intake duct 1 being connected to the air conditioning device 2; the intake duct 1 including a pipe 10 and a duct air supply fan 12 installed within the pipe 10; the outlet of the air conditioning device 2 being connected to the first air supply duct 3; and the end of the first air supply duct 3 having multiple outlet ducts 31; a small duct air supply fan 41 installed inside the outlet of each outlet duct 31; and the small duct air supply fan 41 blowing fresh air supplied by the air conditioning device 2 into the room.

[0027] The exhaust system described above includes an exhaust pipe 5, and a plurality of suction pipes 51 are provided at the end of the exhaust pipe 5. A small duct suction fan 7 is installed in the pipe opening of each suction pipe 51. The small duct suction fan 7 draws in the indoor stale air and then delivers it to the outside through the exhaust pipe 5 in sequence. A duct exhaust fan 6 is installed in the front end of the exhaust pipe 5.

[0028] The aforementioned new fresh air system also includes a central control system 8, and a terminal control system 4 is installed at the inlet of each of the air outlet pipes 31. The terminal control system 4 controls the operation of the small duct air supply fan 41, and the central control system 8 sends control commands to the terminal control system 4.

[0029] The aforementioned central control system 8 controls the operation of the duct supply fan 12, the air conditioning device 2, the small duct suction fan 7, and the duct exhaust fan 6.

[0030] The aforementioned air conditioning device 2 includes a filter 21, a surface cooler 22, and a humidifier 23, which are installed in a housing 24.

[0031] The central control system 8 described above is also connected to several infrared / temperature sensing systems 44. These systems sense the status of user positions near the outlet of the air duct 31 and send the sensing signals to the central control system 8. The central control system 8 then controls the operation of each small duct air supply fan 4 based on these sensing signals. The aforementioned user position status includes the presence / absence of user sensing, temperature sensing, and sleep sensing. The infrared / temperature sensing systems 44 identify whether a user is at the seat, whether the user is asleep, and whether the user's body temperature is too high or too low. The central control system then automatically adjusts the temperature and airflow to the optimal level for each user position, improving user comfort and saving energy.

[0032] The air delivery angle of the aforementioned small duct air supply fan 4 is adjustable, making it more convenient to use.

[0033] This novel fresh air exchange system eliminates the need for a large-volume air supply fan, instead installing a duct air supply fan 12 within the ductwork. Simultaneously, a small duct air supply fan 41 is added inside the terminal duct of the air conditioning outlet. The siphon effect creates negative pressure within the duct, improving the energy efficiency of the fresh air exchange system and reducing energy consumption. Furthermore, the system incorporates sensors for presence, temperature, and sleep status at the air outlet, automatically adjusting the speed of the small terminal duct air supply fan 41 based on the different needs and states of people in different rooms, providing the most comfortable experience for occupants.

[0034] The present invention has the following advantages: 1. The present invention retains the traditional fresh air exchange function, and replaces the volute fan in the traditional fresh air exchange system with a small high-speed fan structure inside the duct, thereby reducing the size of the fresh air system equipment, saving room space, and reducing costs; 2. The fresh air exchange system of the present invention eliminates the traditional fan, and by installing duct air supply fans at the air inlet and outlet of the duct, a siphon effect is formed in the duct to generate negative pressure, reducing the air volume attenuation in the duct and improving the air supply efficiency of the fan system; 3. The fresh air exchange system of the present invention has an independent control unit (i.e., the terminal control system 4) at each terminal air outlet, which controls the small duct air supply fan 41 at each air outlet respectively; at the same time, there is also a centralized control system (i.e., the central control system 8) in the central control console, which can differentiate the speed of the small duct air supply fan 41 at each terminal air outlet. 4. The fresh air exchange system of this utility model is equipped with a terminal control system 4 at the end of each air outlet. People in different rooms can set different fan speeds according to their individual needs, better meeting the differentiated needs of the rooms and improving the experience of the people. 5. The fresh air exchange system of this utility model adds an infrared / temperature sensing system at the end of each air outlet. This system can identify whether there are people in the room, detect whether people are sleeping, and automatically adjust the optimal fan speed for different rooms through a centralized control system, improving the overall efficiency of the fresh air exchange equipment and enhancing the comfort of the people in the room.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it.
