Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The applicant finds that when the engine is started to drive the air conditioner to refrigerate in a parking state in the research process of the fuel dump truck, the engine is in an idle starting state, and the vehicle is in a concentrated fuel injection state in the idle state. In other words, when the fuel dump truck is idling, the valve is small, and the oil sprayer can spray high-concentration engine oil to ensure the operation of the engine of the fuel dump truck. Therefore, the specific fuel consumption of the fuel dump truck is high in the idle state, the combustion efficiency is low, and carbon deposition is easier to cause. In addition, insufficient combustion of fuel also causes a rapid increase in the concentration of carbon monoxide in the vehicle, which is a problem in that safety hazards are easily formed.
Based on the above, an embodiment of the present application provides a vehicle-mounted air conditioner control system, which controls a vehicle-mounted power supply to supply power to an air conditioner system when a vehicle is in a parking state by determining whether the vehicle is in the parking state, and prevents an engine from entering an idle stage when the air conditioner is used in the parking state of the vehicle, so as to improve fuel combustion efficiency and specific fuel consumption of the vehicle and improve safety of a cab.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a vehicle-mounted air conditioner control system according to an embodiment of the present application. The in-vehicle air conditioning control system 10 may be applied to a fuel vehicle, and may include:
a vehicle-mounted power supply 11 including a storage battery;
an air conditioning system 12; for regulating the temperature in the vehicle;
a controller 13; the controller 13 is connected with the vehicle-mounted power supply 11 and the air conditioning system 12 respectively; the controller 13 is configured to determine whether the vehicle is in a parking state, and control the vehicle-mounted power supply 11 to supply power to the air conditioning system 12 when the vehicle is in the parking state.
In the embodiment of the present application, the vehicle-mounted power supply 11 is not a power source of a vehicle, and the vehicle-mounted power supply 11 of the fuel dump truck is described by taking the vehicle as an example, and the vehicle-mounted power supply 11 of the fuel dump truck may be a storage battery, and the storage battery may be a nickel-cadmium battery, a nickel-hydrogen battery, a lithium ion battery, a lithium polymer battery or a lead-acid battery, or may be other types of batteries.
The air conditioning system 12 may be an original air conditioning system in a fuel dump truck for adjusting the temperature in the vehicle; by using the air conditioning system of the original vehicle, the system pipeline does not need to be changed, so that the implementation cost of the system can be reduced. And in the case that the air conditioning system 12 is used along the traditional fuel vehicle air conditioning pipeline, the heat exchanger can be not additionally arranged in the cab, the overall tightness of the cab can be kept, and the safety and the driving experience of the cab can be improved.
The controller 13 may be connected to the vehicle-mounted power supply 11 and the air conditioning system 12 by a wired connection or by a wireless connection, and the controller 13 may be an integrated control element or may be separately provided in a plurality of components in the fuel dump truck.
Specifically, the controller 13 may determine whether the vehicle is in a parking state according to a running state of the vehicle, and the manner of determining the running state of the vehicle may be to determine the running state of the vehicle according to a real-time speed of the vehicle obtained by the vehicle speed sensor; acquiring acceleration information of the vehicle through an acceleration sensor to judge the running state of the vehicle; acquiring braking information of the vehicle through a braking sensor to judge the running state of the vehicle; acquiring position information of the vehicle through a GPS positioning system to judge the running state of the vehicle; or the combination of the above modes.
Taking a vehicle speed sensor as an example, the vehicle speed sensor can be a magneto-electric vehicle speed sensor or a photoelectric vehicle speed sensor, and the running state of the vehicle can be obtained by representing the magnitude of the vehicle speed through the amplitude of a sensor signal. If the vehicle is in a parked state and the engine of the vehicle is turned off at this time, the generator of the vehicle stops running, and the vehicle-mounted power source 11 can discharge to supply power to the air conditioning system 12.
Therefore, the vehicle-mounted air conditioner control system provided by the embodiment of the application can control the vehicle-mounted power supply to supply power to the air conditioner system when the vehicle is in the parking state by judging whether the vehicle is in the parking state, can avoid the engine from entering an idle stage when the vehicle uses the air conditioner in the parking state, improves the fuel combustion efficiency and specific fuel consumption of the vehicle, and prevents carbon monoxide from being generated due to insufficient combustion of fuel, thereby being capable of ensuring the safety of a cab.
Referring to fig. 2, fig. 2 is a schematic structural diagram of an air conditioning system according to an embodiment of the present application. The air conditioning system 12 may include:
a compressor 121, an evaporator 122, a condenser 123, a first fan 124, and a second fan 125, wherein the compressor 121 is connected to the vehicle-mounted power supply 11, the evaporator 122, and the condenser 123, the evaporator 122 is connected to the condenser 123 and the first fan 124, and the condenser 123 is connected to the second fan 125;
the controller 13 is specifically configured to control the compressor 121, the first fan 124, and the second fan 125 to enter a parking working mode if it is determined that the vehicle is in a parking state, where the parking working mode characterizes that the compressor 121 sequentially performs a full rotation operation and a variable frequency operation, the first fan 124 adjusts a rotation speed in response to air-conditioning gear information of the vehicle, and the second fan 125 is automatically turned on.
The compressor 121 may be an electronic scroll compressor for compressing air to a high pressure, flowing it into the condenser 123, and then radiating heat through a heat exchanger to facilitate cooling and heating, powering a refrigeration cycle.
In the prior art, the compressor is connected to the engine of the vehicle by a rigid connection, which serves to connect the compressor to the engine so that the compressor can be operated with the power provided by the engine. Unlike the present application, the power source of the compressor 121 is provided by the vehicle-mounted power source 11, so that the rigid connection between the compressor 121 in the air conditioning system 12 and the engine of the vehicle is eliminated, thereby avoiding the consumption of the power of the engine by the compressor 121, reducing the abrasion and aging acceleration of the components, improving the fuel economy of the vehicle and prolonging the service life of the components. In addition, the rigid connection may cause vibration and noise of the compressor to be transmitted to the engine and the vehicle body, and the elimination of the rigid connection may reduce noise and vibration, thereby improving driving and riding comfort.
The first fan 124 and the second fan 125 are both powered by the vehicle power supply 11, the first fan 124 is used for blowing air through the evaporator 122 to evaporate condensed water on the evaporator 122, thereby absorbing heat in ambient air, and the second fan 125 is used for increasing a heat dissipation area of the condenser 123 for introducing air into the condenser 123, thereby improving efficiency of the air conditioning system 12. Relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions in embodiments of the present application.
Specifically, when the controller 13 determines that the fuel dump truck is in the parking state based on the running state of the fuel dump truck, at this time, the engine of the fuel dump truck is turned off, the generator stops running, the controller 13 controls the vehicle-mounted power supply 11 to discharge to supply power to the compressor 121, the second fan 125 is automatically turned on, the first fan 124 adjusts the rotation speed along with the air conditioning gear of the user, when the air conditioning gear is high, the rotation speed of the first fan 124 is high, and when the air conditioning gear is reduced, the rotation speed of the first fan 124 is reduced. The compressor 121 may be configured to run at full rotation during the just-on phase of parking, then run at variable frequency or gradually slow down until running at the lowest speed, thereby achieving constant cooling energy saving.
Optionally, after detecting that the fuel dump truck is in the parking state for too long, if the power supply electric quantity is lower than the running minimum value, the electric quantity signal can be fed back to the controller 13, and the engine can be started to charge the storage battery at the moment so as to realize power supply electric quantity protection.
Therefore, according to the embodiment of the application, the controller can control the air conditioning system to enter the parking working mode when determining that the vehicle is in the parking state, and the compressor, the first fan and the second fan are matched in a coordinated manner to realize refrigeration adjustment according to the temperature adjustment requirements, so that the energy-saving and constant-cooling refrigeration effects can be achieved according to different refrigeration requirements.
In an alternative embodiment, air conditioning system 12 may further include a temperature and pressure sensor 126, wherein temperature and pressure sensor 126 is respectively connected to controller 13, evaporator 122, and condenser 123 for collecting and feeding back temperature and pressure information of the gas.
Referring to fig. 3, fig. 3 is a schematic structural diagram of another air conditioning system according to an embodiment of the present application. The plurality of temperature and pressure sensors 126 may be provided in front of and behind the condenser 123 and the evaporator 122, respectively, and collect temperature information and pressure information in the cold cycle, and the temperature information and the pressure information are fed back to the controller 13 to obtain the thermal load in the vehicle.
The controller 13 may also be used to control the rotational speed of the compressor 121 based on the thermal load. The rotation speed of the compressor 121 can be feedback-regulated according to the signal received by the controller 13 from the temperature and pressure sensor 126: when the thermal load is high, the full rotation speed of the compressor 121 can be controlled to run, when the temperature in the cab is stable, and when the thermal load is reduced, the compressor 121 can be controlled to run at a low rotation speed, and the subsequent controller 13 can also adjust the rotation speed of the compressor 121 according to the change of the thermal load in the vehicle and the requirement of a driver fed back by the temperature and pressure sensor 126.
Therefore, in the embodiment of the application, the temperature and pressure changes in the refrigeration cycle are monitored by arranging the temperature and pressure sensor, and the air conditioning system is automatically regulated and controlled by the controller, so that the refrigeration efficiency and the energy-saving effect of the air conditioning system can be improved. Faults and anomalies in the refrigerating system, such as refrigerant leakage, valve faults and the like, can be timely found through the arrangement of the temperature and pressure sensor, so that the safety and stability of the air conditioning system are guaranteed.
Optionally, the vehicle-mounted power supply 11 is connected to an engine of the vehicle, and the controller 13 is further configured to control the engine to charge the vehicle-mounted power supply 11 and supply power to the air conditioning system 12 when the vehicle is in an out-of-park state.
The manner in which the controller 13 determines whether the vehicle is in the non-parking state may be referred to in the above description. And will not be described in detail herein. If the controller 13 determines that the vehicle is in the non-parking state, the engine is started at this time, and drives the generator to charge the vehicle-mounted power supply 11 and supply power to the air conditioning system 12. The charging and discharging of the vehicle-mounted power supply 11 can be regulated by the engine in a complementary manner, so that the charging of an efficient area of the engine is realized, the running of an inefficient area of the engine is stopped, the discharging of the vehicle-mounted power supply 11 can improve the utilization rate of the whole vehicle, the power output of the vehicle is increased, and the running performance of the vehicle is improved.
