Problems solved by technology

[0003] In the prior art, for logistics vehicles, the co-pilot is unmanned most of the time. If the cooling demand of the co-pilot space is not ignored at this time, part of the energy consumption of the air conditioner will be unnecessarily increased, and there are many points in the cab. The temperature changes greatly, for example, there are heat sources such as controllers, car glass, and car shells. A temperature sensing package in the car cannot meet the sampling requirements, resulting in variable temperatures in the cab and poor comfort. At the same time, the air supply strategy is single and not more intelligent. Therefore, the present invention proposes a regional air supply method, device and air conditioner to solve the problems existing in the prior art

Embodiment 1

[0102] according to figure 1 , 2 As shown, this embodiment proposes a regional air supply method, which is applied to a logistics vehicle. A pressure sensor is installed under the passenger seat of the logistics vehicle, and three air outlets are provided in the cab of the logistics vehicle. According to whether there is anyone in the co-pilot, the air outlet and air supply strategy can only be changed to meet the space cooling needs of people. The 12 corners of the cab of the logistics vehicle are equipped with temperature sensor devices, which can detect the temperature of different areas of the cab at any time and adjust the temperature accordingly. The direction of the air supply improves the comfort of the air conditioner, see figure 1 ; The regional air supply method comprises the following steps:

[0103] When the car starts to drive, judge whether there is a person in the co-pilot according to the pressure sensor of the co-pilot;

[0104] When the co-pilot is occupi...

Embodiment 2

[0109] according to image 3 , 4 As shown, this embodiment proposes a regional air supply method, which is applied to logistics vehicles. The sweeping control strategy includes a horizontal direction strategy and a vertical direction strategy. The horizontal direction strategy includes the following steps:

[0110] Take a, b, c, d, four sampling temperatures, and find the difference Delta_T(x, y). If Delta_T(x, y) is equal to 0, it is considered that the temperature in the horizontal direction of the cab is uniform and relatively comfortable. wind strategy.

[0111] The sweeping time at a uniform speed is t, and the sweeping time at the three 60-degree sweeping angles is t / 3 on average; see image 3 ,

[0112] When at least one value of Delta_T(x, y) is not equal to 0, it is considered that the temperature in the horizontal direction of the cab is not uniform, and the average value of the sampling temperature is taken

[0113] E(T)=(Ta+Tb+Tc+Td) / 4;

[0114] For the differ...

Embodiment 3

[0133] This embodiment proposes a regional air supply method device, including an acquisition module, a detection module, a judgment module and a control module:

[0134] The collection module is used to collect temperature data sampled by the temperature sensor device;

[0135] The detection module is connected to a pressure sensor to determine whether there is anyone in the co-pilot;

[0136] The judging module is used to judge whether the cab temperature is uniform;

[0137] The control module is used to determine the sweeping control strategy.

Abstract

The invention provides a regional air supply method and device and an air conditioner, and relates to the technical field of air conditioner air supply, the regional air supply method and device are applied to a logistics vehicle, a pressure sensor is installed below a co-driver seat of the logistics vehicle, an air outlet is formed in a cab of the logistics vehicle, and a temperature sensor device is installed at the corner in the cab of the logistics vehicle; the pressure sensor is arranged below the co-driver seat, the air outlet is formed in the cab, the air outlet and the air supply strategy are changed according to whether a passenger exists in the co-driver or not in the driving process, and the space refrigeration requirement of the passenger is met; temperature sensor devices are installed at multiple corners of the cab to detect the temperature of different areas of the cab at any time so as to adjust the air supply direction to improve the comfort of the air conditioner, a more intelligent control method is achieved, in conclusion, the air supply requirement of the co-driver can be ignored when no one is in the co-driver, air conditioner energy consumption is reduced, and energy is saved; the air conditioning state of the cab can be more accurately grasped through multi-point temperature sampling, and comfort is improved.

Description

technical field [0001] The invention relates to the technical field of air-conditioning air supply, in particular to a regional air-supply method, device and air conditioner. Background technique [0002] Under the background that the country vigorously develops new energy vehicles to achieve carbon peaking, electric new energy vehicles are widely popularized. Since the energy storage of electric vehicles has disadvantages compared with gasoline vehicles, new energy vehicles need to save the energy consumed by the load on the vehicle as much as possible. For pure electric logistics vehicles, the air conditioner in the cab consumes a lot of energy, so it is particularly important to make the air conditioner in the cab as energy-efficient as possible while ensuring comfort; [0003] In the prior art, for logistics vehicles, the co-pilot is unmanned most of the time. If the cooling demand of the co-pilot space is not ignored at this time, part of the energy consumption of the a...
