[0062] Since the existing air-conditioning system adopts a single system design, the unit has poor ability to regulate the ambient temperature during operation and can only be operated in full closure or full opening. It is impossible to adjust the capacity in stages according to environmental requirements. In addition, due to the lack of redundant design functions, as long as any component such as the air-conditioning power supply, compressor, condensing fan, etc. fails during operation, the air-conditioning system will not be able to work normally, causing large fluctuations in the ambient temperature of the driver and passengers and poor comfort. It is easy for the driver and passengers to suffer from dizziness, heat stroke, colds and other diseases and physical discomfort due to high temperature, humidity and drastic temperature changes, affecting the health of the driver and passengers and the safety of train operations. Therefore, the present application proposes a locomotive-based air-conditioning system.

[0063] Example 1

[0064] An embodiment of the present application provides a locomotive-based air conditioning system.

[0065] See also Figure 1 , Figure 1 A schematic diagram of a locomotive-based air conditioning system provided by an embodiment of the present application is shown, comprising: a monitoring module 100, a first refrigeration module 200 and a second refrigeration module 300; the monitoring module 100 is respectively connected to the first refrigeration module 200 and the second refrigeration module 300 for communication, and is used to determine whether the first refrigeration module 200 or the second refrigeration module 300 fails, and determine a normal refrigeration module and an abnormal refrigeration module in the first refrigeration module 200 and the second refrigeration module 300 according to the judgment result, and control the abnormal refrigeration module to be disconnected, and switch the normal refrigeration module to be used; the first refrigeration module 200 comprises: a first power submodule 202, a first control submodule 203, and a second refrigeration module 204; Module 201, a first heating submodule 203 and a first refrigeration submodule 204; the second refrigeration module 300 includes: a second power submodule 302, a second control submodule 301, a second heating submodule 304 and a second refrigeration submodule 303; the monitoring module 100 is respectively communicated with the first control submodule 201 and the second control submodule 301; the first power submodule 202 is respectively electrically connected to the first control submodule 201, the first heating submodule 203 and the first refrigeration submodule 204; the second power submodule 302 is respectively electrically connected to the second control submodule 301, the second heating submodule 304 and the second refrigeration submodule 303.

[0066] In this embodiment, by adding a power sub-module, the original non-redundant function is improved to a cold standby redundant function, that is, when one of the power sub-modules is detected to be abnormal, it is only necessary to switch to another group of cold standby power sub-modules through the switching switch on the air-conditioning power panel, so that the system can continue to be used, reducing the power supply problem of the locomotive air-conditioning system caused by system failure, and further ensuring the normal operation of the locomotive air-conditioning system.

[0067] Furthermore, two independent cooling and heating systems are designed, that is, when one of the cooling sub-modules or the heating sub-module fails, the other sub-module can operate independently, thus avoiding drastic temperature changes, improving the comfort and reliability of drivers and passengers, and providing protection for locomotive operations.

[0068] In one embodiment, the first power submodule 202 includes: a first switch unit 2021, a first sensor unit 2022, a first power unit 2023, a first filter unit 2024, and a second switch unit 2025; the first power unit 2023 is electrically connected to the first sensor unit 2022 and the first filter unit 2024, respectively, for converting the first input power into a first working power; the first switch unit 2021 is electrically connected to the first control submodule 201 and the first sensor unit 2022, respectively; the second switch unit 2025 is electrically connected to the first filter unit 2024, the first heating submodule 203, and the first cooling submodule 204, respectively, for providing the first working power to the first heating submodule 203 and the first cooling submodule 204; the second power supply submodule 302 includes: a third switch unit 3021, a second sensor unit 3022, a second power unit 3023, a second filter unit 3024 and a fourth switch unit 3025; the second power unit 3023 is electrically connected to the second sensor unit 3022 and the second filter unit 3024, respectively, for converting the second input power supply into a second working power supply; the third switch unit 3021 is electrically connected to the second control submodule 301 and the second sensor unit 3022, respectively; the fourth switch unit 3025 is electrically connected to the second filter unit 3024, the second heating submodule 304 and the second refrigeration submodule 303, respectively, for providing the second working power supply to the second heating submodule 304 and the second refrigeration submodule 303.

[0069] like Figure 2 As shown, the first switch unit 2021 includes a first contactor KM1, the second switch unit 2025 includes a first circuit breaker QA1, the first sensor unit 2022 includes a first current sensor A1, the first power unit 2023 includes a first power converter D1, the first filter unit 2024 includes a first output filter F1, the third switch unit 3021 includes a second contactor KM2, the fourth switch unit 3025 includes a second circuit breaker QA2, the second sensor unit 3022 includes a second current sensor A2, the second power unit 3023 includes a second power converter D2, and the second filter unit 3024 includes a second output filter F2.

[0070] Specifically, the first contactor KM1 and the second contactor KM2 can be controlled to be attracted by manual switching, that is, when the switch is switched to the first power submodule 202, the coil of the KM1 contactor is energized and attracted, and the external AC220V power supply is provided to the first power converter, and the main circuit enters the working state. That is, at this time, the first power converter D1 converts the AC220V power supply into 3AC380V power supply, and after filtering through the rear-end first output filter F1, a stable sinusoidal wave voltage is output. At this time, when the first circuit breaker QA1 in the system circuit is in the closed position, 3AC380V power supply can be provided to the air-conditioning unit inside the air-conditioning system to ensure normal operation of the air-conditioning unit after power is supplied.

[0071] When the switch is switched to the second power supply submodule 302, the coil of the first contactor KM1 loses power and is disconnected, the coil of the second contactor KM2 is energized and closed, and the external AC220V is supplied to the second power converter, and the main circuit enters the working state. That is, the second power converter converts the AC220V power supply into 3AC380V power supply, and outputs a stable sinusoidal wave voltage after filtering through the back-end output filter. When the second circuit breaker QA2 in the system is in the closed position, 3AC380V power supply can be provided to the air-conditioning unit inside the air-conditioning system to ensure the normal operation of the air-conditioning unit after power is supplied.

[0072] In one embodiment, it also includes: a ventilation submodule 500 and a condensation submodule 600; the ventilation submodule 500 is connected to the first refrigeration submodule 204 and the second refrigeration submodule 303 respectively; the condensation submodule 600 is connected to the first refrigeration submodule 204 and the second refrigeration submodule 303 respectively.

[0073] In one embodiment, the ventilation sub-module 500 includes: a ventilator and an evaporation device; the condensation sub-module 600 includes: a condensation device and a condensation fan; a ventilator is arranged corresponding to the evaporation device; a condensation fan is arranged corresponding to the condensation device; the evaporation device is respectively connected to the first refrigeration sub-module 204 and the second refrigeration sub-module 303; the condensation device is respectively connected to the first refrigeration sub-module 204 and the second refrigeration sub-module 303 channels.

[0074] like Figure 3 As shown, it includes two groups of independent refrigeration sub-modules, which can not only prevent system low-pressure failure caused by full-load refrigeration when the air supply volume is reduced or the ambient temperature is low in the transition season, but also can be used to adjust the refrigeration capacity in stages according to actual needs, that is, the first refrigeration sub-module 204 and the second refrigeration sub-module 303 can be closed at the same time according to the temperature, so as to speed up the temperature adjustment, improve the temperature comfort in the car and avoid drastic temperature changes caused by frequent startup of the compressor.

[0075] In one embodiment, the first refrigeration submodule 204 includes: a first compression device 2042, a first throttling device 2041 and a first drying device 2043; the first compression device 2042 is respectively connected to the evaporation device and the condensation device; the second end of the first throttling device 2041 is electrically connected to the first end of the first drying device 2043; the first end of the first throttling device 2041 is connected to the evaporation device; the second end of the first drying device 2043 is connected to the condensation device; the second refrigeration submodule 303 includes: a second compression device 3032, a second throttling device 3031 and a second drying device 3033; the second compression device 3032 is respectively connected to the evaporation device and the condensation device; the second end of the second throttling device 3031 is electrically connected to the second end of the second drying device 3033; the second end of the second throttling device 3031 is connected to the evaporation device; the second end of the second drying device 3033 is connected to the condensation device. Optionally, the first throttling device 2041 is a first thermal expander, and the second throttling device 3031 is a second thermal expander.

[0076] like Figure 3 As shown, the first compression device 2042 is a first compressor, the first drying device 2043 is a first drying filter, the evaporation device is an evaporator, the condensation device is a condenser, the second compression device 3032 is a second compressor, and the second drying device 3033 is a second drying filter.

[0077] The refrigeration submodule mainly includes the following steps when performing refrigeration: condensation, throttling, and evaporation. Condensation means that the high-temperature and high-pressure refrigerant gas discharged from the compressor flows into the condenser through the exhaust pipe. The air volume of the condensing fan is used to accelerate the heat dissipation of the condenser, and the condensing air is discharged by the fan after absorbing heat. At the same time, the high-temperature and high-pressure refrigerant gas releases heat and condenses into a medium-temperature and high-pressure refrigerant liquid in the condenser. Throttling means that the medium-temperature and high-pressure refrigerant flowing out of the condenser passes through a drying filter to remove impurities and moisture in the refrigerant and then flows into the thermal expansion valve. After throttling, the temperature and pressure of the refrigerant are greatly reduced, and the medium-temperature and high-pressure refrigerant liquid will be throttled into a low-temperature and low-pressure refrigerant gas-liquid mixture; evaporation means that the refrigerant enters the evaporator after throttling, and the refrigerant will absorb the heat in the incoming air and evaporate continuously, turning into refrigerant superheated steam.

[0078] During cooling, the mixed air flow passes through the evaporator to release heat and cool down, then is sucked in by the blower and sent into the driver's cab through the air supply duct, absorbing heat and moisture from the indoor air, thereby reducing the indoor air temperature and humidity, thereby achieving the purpose of cooling and dehumidifying the compartment.

[0079] This system has two sets of independent refrigeration sub-modules. During its operation, if a single refrigeration circuit fails, the control sub-module inside the air-conditioning system can automatically detect the corresponding failed refrigeration circuit, thereby realizing the system's automatic switching of the refrigeration circuit function, so that the refrigeration function of the air-conditioning system can be used normally, without affecting the ambient temperature of the locomotive caused by the ambient temperature out of control due to the refrigeration system failure.

[0080] In one embodiment, the first heating submodule 203 includes: a first heating contactor 2031 and a first heating device 2032; the first heating contactor 2031 is electrically connected to the first power submodule 202 and the first heating device 2032 respectively; the first control submodule 201 is communicatively connected to the first heating contactor 2031, and is used to control the first heating contactor 2031 to be disconnected when the first heating device 2032 fails; the second heating submodule 304 includes: a second heating contactor 3041 and a second heating device 3042; the second heating contactor 3041 is electrically connected to the second power submodule 302 and the second heating device 3042 respectively; the second control submodule 301 is communicatively connected to the second heating contactor 3041, and is used to control the second heating contactor 3041 to be disconnected when the second heating device 3042 fails.

[0081] like Figure 4 As shown, the first heating device 2032 is a first electric heater U1, and the second heating device 3042 is a second electric heater U2. The first heating contactor is a first contactor KM7, and the second heating contactor is a second contactor.

[0082] In this embodiment, the first heating contactor 2031 and the second heating contactor 3041 are controlled by the first control submodule 201 or the second control submodule 301 respectively, that is, when the ambient temperature is lower than the preset temperature threshold, the first heating contactor 2031 will be automatically attracted, the first electric heater U1 will be powered, and the first heating submodule 203 will enter a normal operation state. When the first heating submodule 203 fails during its operation, that is, the first electric heater U1 or the first heating contactor 2031 is abnormal, the first control submodule 201 will automatically control the first heating contactor 2031 to disconnect after detecting the feedback, so that the first electric heater U1 stops working and the second electric heater U2 is activated to start working, so that the heating system maintains normal operation, ensuring that the ambient temperature can realize the heating function, and does not affect the ambient temperature of the locomotive operation due to the ambient temperature out of control caused by the failure of the refrigeration system.

[0083] When the first heating module or the second heating module is enabled, the control module controls the first refrigeration submodule 204 or the second refrigeration submodule 303 to stop running until the ambient temperature is greater than a preset temperature threshold.

[0084] In one embodiment, it includes: a display module 400; the display module 400 is connected to the first power submodule 202, the second power submodule 302, the first control submodule 201 and the second control submodule 301 respectively.

[0085] It should be noted that if Figure 5 As shown, the display module 400 is used to display the working conditions and real-time temperature of the first power submodule 202, the second power submodule 302, the first heating submodule 203, the first refrigeration submodule 204, the second heating submodule 304 and the second refrigeration submodule 303.

[0086] The present application proposes an air conditioning system based on a locomotive, which includes: a monitoring module 100, a first refrigeration module 200 and a second refrigeration module 300; the monitoring module 100 is respectively connected to the first refrigeration module 200 and the second refrigeration module 300 for communication, and is used to determine whether the first refrigeration module 200 or the second refrigeration module 300 fails, and determine a normal refrigeration module and an abnormal refrigeration module in the first refrigeration module 200 and the second refrigeration module 300 according to the judgment result, and control the abnormal refrigeration module to be disconnected, and switch the normal refrigeration module to be used; the first refrigeration module 200 includes: a first power submodule 202, a first control submodule 20 1. The first heating submodule 203 and the first refrigeration submodule 204; the second refrigeration module 300 includes: a second power submodule 302, a second control submodule 301, a second heating submodule 304 and a second refrigeration submodule 303; the monitoring module 100 is respectively connected to the first control submodule 201 and the second control submodule 301 in communication; the first power submodule 202 is respectively electrically connected to the first control submodule 201, the first heating submodule 203 and the first refrigeration submodule 204; the second power submodule 302 is respectively electrically connected to the second control submodule 301, the second heating submodule 304 and the second refrigeration submodule 303. This solution increases the redundancy of the system by adding a new set of refrigeration modules. When any part fails, the refrigeration module can be switched in time, reducing the problem of power outage caused by system failure, further ensuring the normal operation of the locomotive air conditioning system, and avoiding drastic changes in temperature, improving comfort and reliability.

[0087] Example 2

[0088] This embodiment provides an air conditioner, including the locomotive-based air conditioning system provided by the first embodiment.

[0089] In one embodiment, the power supply module 700 includes a charging switch unit; the charging switch unit is electrically connected to the first power submodule 202 and the second power submodule 302 respectively.

[0090] like Figure 6 As shown, the first power submodule 202 and the second power submodule 302 share an input voltage of AC220V, and the charging switch unit is a circuit breaker, which can supply power to the first power submodule 202 and the second power submodule 302 through a closed circuit breaker.

[0091] The present application proposes an air conditioner, including the locomotive-based air conditioning system mentioned in Example 1. This solution increases the redundancy function of the system by adding a new set of refrigeration modules. When any part fails, the refrigeration module can be switched in time, reducing the power outage problem caused by system failure, further ensuring the normal operation of the locomotive air conditioning system, avoiding drastic temperature changes, and improving comfort and reliability.
