Description

Power air vent systems and building air conditioning systems, automotive air conditioning systems Technical Field

[0001] This utility model relates to power air outlet systems, building air conditioning systems, and automotive air conditioning systems. Background Technology

[0002] The existing automotive air conditioning centralized air supply system includes an air intake duct, a cooling / heating system, and an air supply duct, as shown in Figure 1. The air intake duct has two air inlets: one air inlet 1a supplies fresh air, and the other air inlet 2a supplies internal recirculated air. The outlet of the air intake duct is connected to the cooling / heating system, and the outlet of the cooling / heating system is connected to the air supply duct. The cooling / heating system includes a high-power air supply fan 3a and a heat exchanger 4a. The cooling / heating system cools or heats the air in the air intake duct and then delivers it to the air supply duct. At the end of the air supply duct, there are multiple air outlet ducts 5a. The outlet of each air outlet duct 5a is located in a different area of ​​the passenger compartment. At the end of the air outlet duct, there is a valve switch to control the air volume. Existing automotive air conditioning systems have the following drawbacks: 1. High-powered air supply fans are too large and placed in the engine compartment, severely restricting the space layout of the engine compartment; 2. After the high-powered air supply fans deliver cold / hot air, it is transmitted through the air ducts, especially the long-distance duct transmission in the rear area, resulting in significant air volume loss and reducing the energy efficiency of the air supply system; 3. In centralized air supply systems, the air supply fans directly deliver cold / hot air to the end of the air outlet and blow it onto the passengers, causing the passengers' body temperature to change too quickly and reducing comfort; 4. Centralized air supply systems cannot provide differentiated air supply management for each air outlet. Passengers in different positions cannot set different fan speeds according to their individual needs. They can only install valves at each air outlet and intercept airflow by opening and closing the valves, resulting in wasted airflow; 5. In centralized air supply systems, the air supply fans directly deliver cold air to the end of the air outlet and blow it onto the passengers, causing the passengers' body temperature to change too quickly and reducing comfort.

[0003] In addition, as shown in Figure 2, the existing building air conditioning system has the following drawbacks: 1. The indoor unit is too large, wasting room space; 2. The indoor unit is used to adjust the temperature of the entire room indiscriminately, wasting resources; 3. The evaporator is placed in the indoor unit and the compressor is placed in the outdoor unit, which is connected by copper pipes, consuming a large amount of copper pipe material and wasting resources.

[0006] The technical solution of this utility model is implemented as follows:

[0007] A power air outlet system includes an air inlet duct, a cooling / heating system, and an air supply duct. The air inlet duct has an air inlet, and its outlet is connected to the cooling / heating system. The cooling / heating system includes a pipe, a high-power air supply fan installed inside the pipe, and a heat exchanger.

The terminal air supply system mixes the low / high temperature airflow from the cooling / heating system with the ambient temperature airflow in the room and blows it to the user's location.

[0008] The aforementioned low-power air supply fan is located diagonally behind the low-speed fan. The low-power air supply fan blows the low / high-temperature airflow of the cooling / heating system to the rear of the low-speed fan. The low-speed fan mixes the low / high-temperature airflow with the ambient airflow and then blows it to the user's location.

[0009] The aforementioned terminal air supply system also includes an air supply control unit, which controls the operation of the low-power air supply fan and low-speed fan of the terminal air supply system to which it is located.

[0017] Compared with the prior art, this utility model has the following advantages:

[0018] 1. The power air outlet system includes an air inlet duct, a cooling / heating system, and an air supply duct. The air inlet duct has an air inlet, and the air inlet duct outlet is connected to the cooling / heating system. The cooling / heating system includes a high-power air supply fan and a heat exchanger. The outlet of the cooling / heating system is connected to the air supply duct. The air supply duct has multiple air outlet ducts at its end, and a terminal air supply system is provided at the outlet of each air outlet duct.

[0025] 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.

[0026] Example 1:

[0027] As shown in Figure 3, this embodiment provides a power air outlet system, including an air inlet pipe 1, a cooling / heating system 2, and an air supply pipe 3. The air inlet pipe 1 is provided with an air inlet 11, and the outlet of the air inlet pipe 1 is connected to the cooling / heating system 2. The cooling / heating system 2 includes a pipe 20, a high-power air supply fan 21 installed in the pipe 20, and a heat exchanger 22. The outlet of the cooling / heating system 2 is connected to the air supply pipe 3. The end of the air supply pipe 3 is provided with multiple air outlet pipes 31, and a terminal air supply system 4 is provided at the opening of each of the air outlet pipes 31. The terminal air supply system 4 includes a low-power air supply fan 41 and a low-speed fan 42. The low-power air supply fan 41 is located at the end of the air outlet pipe 31, and the low-speed fan 42 is located next to the opening of the air outlet pipe 31. The terminal air supply system 4 mixes the low / high temperature airflow of the cooling / heating system 2 with the ambient temperature airflow in the room and blows it to the user's location.

[0028] The power air outlet system has the following advantages: 1. The low / high temperature airflow blown out by the high-power air supply fan 21 is compensated by a high-speed low-power air supply fan at the end of the air outlet duct, reducing the airflow attenuation of cold air in the air supply duct and improving the air supply efficiency of the fan system; 2. The terminal air supply system mixes the low / high temperature airflow and the ambient temperature airflow to form a mixed-flow natural wind, which is then blown to the user's position, improving the user's comfort; 3. This utility model sets a high-power air supply fan 21 in the duct, and at the same time adds a high-speed small exhaust fan (i.e., a high-speed low-power air supply fan 41 and a low-speed fan 42) at the end of the air conditioning outlet duct to form a power air outlet. Due to the siphon effect, negative pressure is generated in the duct, which improves the energy efficiency of the air conditioning air supply system and reduces energy consumption. 4. Install low-speed fans at the air outlets. Each fan can work independently. Add presence detection, temperature detection, and sleep detection for each person (i.e., user). Automatically adjust the speed of the terminal fans according to the different needs and states of people in different locations to provide the most comfortable experience.

[0029] The aforementioned low-power air supply fan 41 is located diagonally behind the low-speed fan 42. The high-speed low-power air supply fan 41 blows the low / high-temperature airflow from the cooling / heating system 2 behind the low-speed fan 42. The low-speed fan 42 mixes the low / high-temperature airflow with the ambient airflow and then blows it to the user's location. The mixing of the low / high-temperature airflow with the ambient airflow by the low-speed fan 42 makes the air temperature and speed more comfortable.

[0030] As shown in Figure 4, the aforementioned terminal air supply system 4 also includes an air supply control unit 43, which controls the operation of the high-speed, low-power air supply fan 41 and the low-speed fan 42 within the terminal air supply system 4. Users at different locations can set the airflow speed of the terminal air supply system 4 according to their individual needs, better meeting the diverse needs of users and enhancing their user experience.

[0031] The above also includes a central control system 5, which controls the operation of each air supply control unit 43.

[0032] The aforementioned terminal air supply system 4 also includes an infrared / temperature sensing system 44. The infrared / temperature sensing system 44 senses the user's location and sends the sensing signal to the central control system 5. The central control system 5 controls the operation of each air supply control unit 43 based on the sensing signal. The central control system 5 can control the operation of each terminal air supply system 4 differently.

[0033] The air delivery angles of the aforementioned low-power blower 41 and low-speed fan 42 are adjustable; for example, the air delivery angle can be adjusted within the range of 10 degrees to 90 degrees.

[0034] The aforementioned user location status includes whether or not user awareness is present, temperature awareness, and sleep awareness.

[0035] The aforementioned air inlet duct 1 may be provided with two air inlets 11, one of which supplies fresh air and the other supplies internal circulating air.

[0036] The infrared / temperature sensing system 44 identifies whether there is a user in the seat, whether the user is asleep, and whether the user's body temperature is too high or too low. The system then automatically adjusts the temperature and airflow to the optimal level for each user's location through a centralized control system, improving user comfort and saving energy.

[0037] The novel air conditioning system described in this embodiment has high air supply efficiency, a good user experience, and low energy consumption.

[0038] Example 2:

[0039] This embodiment provides an automotive air conditioning system, including a power vent system, characterized in that: the power vent system is the power vent system described in Embodiment 1.

[0040] By improving the power vent system, the car becomes more energy-efficient and the passenger (i.e., user) experience is more comfortable. Its advantages include:

[0041] 1. In automotive applications, the high-power centralized air supply fan inside the engine compartment has been eliminated. Instead, a high-power air supply fan 21 has been added to the centralized air supply duct. This allows for better spatial layout of the engine compartment and improves the rationality of the engine compartment space design.

[0042] 2. In automotive applications, the air blown by the high-power blower 21 is compensated by adding a high-speed, low-power blower in the duct at the end of the air outlet, which creates a siphon effect in the duct to generate negative pressure, reducing the air volume attenuation of cold (or hot) air in the duct and improving the air delivery efficiency of the blower system.

[0043] 3. In automotive applications, each air duct 31 has an independent air supply control unit 43, which controls the low-power air supply fan 41 of each air duct 31 respectively; at the same time, there is also a central control system 6 in the center console for centralized control, which can control the speed of the low-power air supply fan 41 of each air duct 31 differently.

[0044] 4. A low-power air supply fan 41 is installed in each air outlet duct 31. People in different positions can set different speeds of the low-power air supply fan 41 according to their individual needs, which better meets the differentiated needs of the personnel and improves their experience.

[0045] 5. An infrared / temperature sensing system 44 is added to each air outlet duct 31. This system can identify whether there is a person in the seat, whether the person is asleep, and whether the person's body temperature is too high or too low. The system can also automatically adjust the temperature and airflow to the optimal position for different people through the central control system 6, thereby improving the comfort of the people.

[0046] 6. Add a low-speed fan 42 to each air outlet duct 31 to mix the ambient air with the cold (hot) air blown out by the low-power blower 41 and blow it onto the personnel to form a natural breeze and improve the comfort of the personnel.

[0047] 7. The new air conditioning system can achieve constant air volume control, reducing the risk of reduced air volume caused by increased static pressure in the duct due to factors such as filter blockage, and improving the user experience of air conditioning cooling effect.

[0048] Example 3:

[0049] As shown in Figure 5, this embodiment provides a building air conditioning system, including a power air outlet system, characterized in that: the power air outlet system is the power air outlet system described in Embodiment 1.

[0050] The advantages of this embodiment are as follows:

[0051] 1. By placing the heat exchanger 22 and compressor outdoors and delivering cold (hot) air indoors through a duct fan, the size of the indoor unit is reduced, costs are lowered, and room space utilization is improved.

[0052] 2. The air blown out by the centralized high-power air supply fan 21 is compensated by adding a high-speed low-power air supply fan in the duct at the end of the air outlet. This creates a siphon effect in the duct, generating negative pressure, reducing the air volume attenuation of cold (or hot) air in the duct, and improving the air supply efficiency of the fan system.

[0053] 3. Each terminal air outlet has an independent control unit to control the fan of each outlet; at the same time, there is also a centralized control system in the central control panel, which can control the speed of the fan of each terminal air outlet differently.

[0054] 4. Small fan systems are installed at the end of each air outlet. People in different positions can set different fan speeds according to their individual needs, which better meets the differentiated needs of people and improves their experience.

[0055] 5. Add an infrared / temperature sensing system to the end of each air outlet. This system can identify whether there is a person in the seat, whether the person is asleep, and whether the person's body temperature is too high or too low. The system can also automatically adjust the temperature and airflow to the optimal position for different people through a centralized control system, thereby improving the comfort of the people.

[0056] 6. Add a low-speed fan at the end of each air outlet to mix the ambient air with the cold (hot) air blown out by the low-power blower and then blow it onto the personnel to create a natural breeze and improve their comfort.

[0057] 7. The building's air conditioning system can achieve constant air volume control, reducing the risk of reduced air volume due to increased static pressure in the pipes caused by factors such as filter blockage, and improving the user experience of air conditioning cooling effect;

[0058] 8. Building air conditioning systems can automatically adjust the direction of air outlets by adding personnel tracking and detection at the terminal air ducts, thereby maximizing the cooling effect, reducing the overall energy consumption of air conditioning, and improving the experience of personnel.

[0059] 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.
