[0065] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0066] Example 1:

[0067] refer to Figures 1 to 4 The present invention provides an ultra-thin rail vehicle air conditioning unit, which is installed on the top of the passenger compartment of the ultra-thin rail vehicle;

[0068] The air outlet and return air outlet are located at the bottom of the air conditioning unit casing, both facing the passenger compartment of the ultra-thin rail vehicle;

[0069] The air inlet and exhaust outlet are located on the top of the ultra-thin rail vehicle shell, both facing outwards from the ultra-thin rail vehicle.

[0070] The air outlet is connected to the heat exchanger inside the air conditioning unit casing through the first double ventilation duct. An air outlet grille is installed on the end of the first double ventilation duct near the air outlet.

[0071] The return air inlet is connected to the heat exchanger and exhaust vent through a three-way ventilation duct. A return air grille is installed at the end of the three-way ventilation duct near the return air inlet.

[0072] The air inlet is connected to the heat exchanger through a second double ventilation duct, and an air inlet grille is installed on the end of the second double ventilation duct near the air inlet.

[0073] The three ventilation ducts are equipped with a controllable opening and closing state and a first valve that directs the airflow from the return air inlet to the heat exchanger and / or the exhaust air outlet.

[0074] The first double ventilation duct and the second double ventilation duct are respectively equipped with a second valve and a third valve that can control the opening and closing of the pipeline;

[0075] The control module is electrically connected to the air outlet grille, air return grille, air inlet grille, first valve, second valve, and third valve, respectively.

[0076] In this embodiment, the first dual ventilation duct and the second dual ventilation duct are ventilation ducts with only two ports, while the three ventilation duct is a ventilation duct with three ports.

[0077] In this embodiment, the air outlet grille, return air grille, and air inlet grille can all be controlled by the control module to open and close. When they are closed, the airflow cannot enter the corresponding air duct from the corresponding air outlet.

[0078] The working principles and beneficial effects of the above technologies are as follows:

[0079] refer to Figure 2 When the control module receives a control command to adopt an internal circulation temperature regulation strategy, it controls the return air grille and the outlet air grille to open. At the same time, it controls the first valve to make the airflow into the return air inlet flow only through the filter screen to the heat exchanger. Meanwhile, it controls the third valve on the second double-pass pipe to close the second double-pass pipe, and controls the second valve on the first double-pass pipe to make the cooled or heated air flowing out of the heat exchanger discharged from the outlet into the passenger compartment of the ultra-thin rail vehicle.

[0080] refer to Figure 3 When the control module receives a control command to adopt an external circulation temperature regulation strategy, it controls the return air grille, the outlet air grille, and the inlet air grille to open. At the same time, it controls the first valve to make the airflow into the return air inlet flow only through the filter screen to the exhaust air outlet and be discharged from the exhaust air outlet. Meanwhile, it controls the third valve on the second double-pass pipe to open the second double-pass pipe, so that the air outside the vehicle flows into the heat exchanger. It also controls the second valve on the first double-pass pipe to make the cooled or heated air flowing out of the heat exchanger be discharged from the air outlet into the passenger compartment of the ultra-thin rail vehicle.

[0081] refer to Figure 4 When the control module receives a control command to adopt a combined internal and external circulation temperature control strategy, it controls the return air grille, outlet air grille, and inlet air grille to open. At the same time, it controls the first valve to allow the airflow into the return air inlet to pass through the filter and flow to both the exhaust air outlet and the heat exchanger, so that the air flowing into the return air inlet is discharged from the exhaust air outlet. Simultaneously, by controlling the third valve on the second double-pass pipe, the second double-pass pipe is opened, allowing air from outside the vehicle to flow into the heat exchanger. The second valve on the first double-pass pipe is controlled to allow the cooled or heated air flowing out of the heat exchanger to be discharged from the outlet into the passenger compartment of the ultra-thin rail vehicle. At this time, the gas flowing into the heat exchanger comes from outside the vehicle and the passenger compartment.

[0082] Through air outlets, return air inlets, air inlets, exhaust air outlets, air ducts connecting each air outlet and heat exchanger, valves installed on the air ducts, and control modules, the ultra-thin rail vehicle air conditioning unit can provide multiple air circulation temperature control modes as needed, such as internal circulation, external circulation, or a combination of internal and external circulation. This allows the ultra-thin rail vehicle air conditioning unit to control operating costs and ensure operating performance in the diverse temperature control needs and operating environments of ultra-thin rail vehicles.

[0083] Example 2:

[0084] Based on Example 1, filters are installed in the first double ventilation duct, the second double ventilation duct, and the straight pipes in the third ventilation duct that are directly connected to the return air grille.

[0085] The beneficial effects of the above technology are as follows: by installing filters in the straight pipes directly connected to the return air grille in the first double ventilation duct, the second double ventilation duct, and the third ventilation duct, the air is filtered before flowing into the heat exchanger, which greatly reduces the impurities adhering to the internal structure of the air conditioning unit due to the air circulation process in the air conditioning unit, and can extend the service life of the air conditioning unit.

[0091] S4: Based on the strategy evaluation values ​​of the internal circulation temperature control strategy, the external circulation temperature control strategy, and the combined internal and external circulation temperature control strategy, the final temperature control strategy is determined.

[0092] S5: Based on the final temperature control strategy and the above-mentioned control module, control the air outlet grille, air return grille, air inlet grille, first valve, second valve, and third valve to obtain intelligent temperature control results.

[0093] In this embodiment, the real-time air quality index indicates the quality of air in the environment and can be obtained using existing air quality sensors.

[0094] In this embodiment, the target temperature is the output temperature of the air conditioning unit installed in the main control room of the rail vehicle.

[0095] In this embodiment, the real-time temperature at the air inlet of the air conditioning unit is obtained by a thermometer installed at the air inlet of the air conditioning unit.

[0096] In this embodiment, the strategy evaluation value represents the superiority of the corresponding internal circulation temperature control strategy, external circulation temperature control strategy, or combined internal and external circulation temperature control strategy, which is mainly considered from the aspects of operating cost and time required to achieve the goal.

[0097] In this embodiment, based on the final temperature control strategy and the aforementioned control module, the air outlet grille, return grille, inlet grille, first valve, second valve, and third valve are controlled to obtain an intelligent temperature control result. That is, according to the final temperature control strategy, the control module controls the opening and closing of the air outlet grille, return grille, and inlet grille, as well as the on / off state of the pipes containing the first valve, second valve, and third valve, so that the air conditioning unit performs air circulation and temperature control according to the final temperature control strategy to meet the control requirements of the air conditioning unit.

[0098] The beneficial effects of the above technologies are as follows: Based on the real-time air temperature, real-time air quality index, target adjustment temperature, and real-time air temperature and real-time air quality index at the air inlet of the air conditioning unit, the strategy evaluation values ​​of the internal circulation temperature control strategy, the external circulation temperature control strategy, and the combined internal and external circulation temperature control strategy are analyzed. Based on the strategy evaluation values, the air circulation temperature control method finally adopted in this temperature control process is selected, so that the operating cost of the air conditioning unit of the ultra-thin rail vehicle can be controlled and the operating effect can be guaranteed in the diverse temperature control needs and operating environment of the ultra-thin rail vehicle.
