[0002] The existing automobile air conditioning centralized air supply system includes an air inlet duct, a cooling / heating system and an air supply duct, such as Figure 1 As shown, the air inlet duct is provided with two air inlets, one air inlet 1a is used to deliver fresh air, and the other air inlet 2a is used to deliver internal circulating air. The outlet of the air inlet 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.

A plurality of air outlet ducts 5a are provided at the end of the air supply duct. The outlets of the air outlet ducts 5a are located in different areas of the automobile passenger compartment. A valve switch is provided at the end of the air outlet duct to control the air output. The existing automobile air conditioning air supply system has the following disadvantages: 1. The high-power air supply fan is large in size and is placed in the automobile engine compartment, which seriously restricts the spatial layout of the engine compartment; 2. After the high-power air supply fan sends out the cold air / hot air, it is transmitted through the pipeline of the air supply duct, especially the long-distance pipeline transmission in the rear area, which causes serious air volume loss and reduces the energy efficiency of the air supply system; 3. The air supply fan of the centralized air supply system directly sends the cold air / hot air to the end of the air outlet duct and blows it onto the passengers, causing the passengers' body temperature to change too quickly and reducing their comfort; 4. The centralized air supply system cannot perform differentiated air supply management on the ends of each air outlet. Passengers in different positions cannot set different fan speeds according to their respective needs. They can only set valves at each air outlet to intercept the air volume by switching the size of the valve, resulting in air volume waste; 5. The air supply fan of the centralized air supply system directly sends the cold air to the end of the air outlet and blows it onto the passengers, causing the passengers' body temperature to change too quickly and reducing their comfort.

[0003] In addition, if Figure 2 The working principle of the existing building air conditioning and air supply system is shown in the figure.

Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1:

[0027] 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 the high-speed low-power air supply fan at the end of the air outlet duct, thereby reducing the air volume attenuation of the cold air in the air supply duct and improving the air supply energy 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 natural wind, which is then blown to the user's position to improve the user's comfort; 3. The utility model arranges a high-power air supply fan 21 in the pipeline, 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 terminal pipeline position of the air outlet of the air conditioner to form a power air outlet, and generates negative pressure in the pipeline due to the siphon effect, thereby improving the energy efficiency of the air supply system of the air conditioner and reducing energy consumption. 4. Set a low-speed fan at the air outlet. Each fan can work independently, and add personnel presence, temperature perception, and sleep perception for each personnel (i.e. user) position. According to the different needs and different states of personnel in different positions, the speed of the terminal fan is automatically adjusted to give personnel the most comfortable experience.

[0028] The low-power air supply fan 41 is located obliquely behind the low-speed fan 42. The high-speed low-power air supply fan 41 blows the low / high temperature airflow of the cooling / heating system 2 to the rear of the low-speed fan 42. The low-speed fan 42 mixes the low / high temperature airflow with the ambient temperature airflow and blows it to the user's position.

[0032] The air supply angles of the above-mentioned low-power air supply fan 41 and low-speed fan 42 are both adjustable, for example, the air supply angle can be adjusted within the range of 10 degrees to 90 degrees.

[0033] The above-mentioned user location status includes user perception, temperature perception and sleep perception.
