Description

Air conditioner driving system for commercial vehicles for both heating and cooling

The present invention relates to an air conditioner for commercial vehicles, and more particularly, in developing an air conditioner for commercial vehicles that is driven by low power based on a heat pump, and uses battery power of the vehicle when the operation of commercial vehicles such as trucks is stopped It operates an air conditioner driven by low power based on a heat pump that receives battery power from a commercial vehicle without starting. In particular, it is charged using an energy source of sunlight during normal times, and the generator of the vehicle is used as an energy source when a commercial vehicle such as a truck is operated. The present invention relates to a driving system for air conditioning for commercial vehicles combined with cooling and heating, which increases charging efficiency by charging the air conditioner, and stops cooling and heating operation for the operation of the commercial vehicle when the external temperature reaches a significantly extreme situation during operation of the air conditioner.

In general, commercial vehicles, including trucks, start their engines by burning fuel such as diesel, gasoline, or gas, and drive the vehicle through such engine start-up.

As such, the electricity required during operation of the commercial vehicle is supplied from the generator of the vehicle according to the operation of the engine. By receiving electricity from the vehicle generator and operating the air conditioner to keep the interior of the vehicle cool, the driver can safely operate the commercial vehicle.

In general, among commercial vehicles, trucks usually carry cargo and drive long distances at night, and sleep in the space behind the driver's seat while parked in a place such as a rest area during night driving. In this case, you need to cool off in the summer and warm up in the winter so you can rest comfortably.

However, there is a problem in that it is difficult to operate the electric appliances because it is difficult to receive electricity from the generator of the engine because long-term idling is prohibited according to related regulations.

Therefore, it is necessary to provide an environment where electric appliances can be used without starting the engine of a commercial vehicle such as a truck, so that a person can rest comfortably.

In addition, recently, as vehicles are used for camping, camping vehicles operate electric appliances using a vehicle battery while the engine is stopped. However, since the battery of a vehicle generally has a limited capacity to be used when the vehicle engine is started, there is a concern that the battery may be rapidly consumed when other electric appliances are used without the engine running. Therefore, in the case of camping, there is a disadvantage in that a separate auxiliary battery is used.

As such, it is necessary to have a technical configuration capable of stably receiving power over a long period of time without power supply from an engine generator in a commercial vehicle such as a truck or a camping vehicle.

In addition, in the operation of commercial vehicles or camping vehicles, there is a concern that extremely low or extremely high temperatures may occur frequently, and in the case of such external environmental factors, it is possible to achieve stable operation of commercial vehicles or camping vehicles as well as cooling and heating operations. A technical proposal is required.

Accordingly, the present invention relates to a driving control method of a parking air conditioner, which is charged by receiving power from a vehicle battery (12) charged by an engine generator (11) mounted on a commercial vehicle and power from a solar cell panel (13). A method for controlling a driving system of an air conditioner without operation including a parking air conditioner (20) operated for heating and cooling with the charged power of the conditioner battery (14) is performed.

Looking at the detailed steps of the method for controlling the non-moving air conditioner driving system, a conditioner battery charging step (S1) of charging the conditioner battery 14 with the power of the vehicle battery 12 and the charged power of the solar cell panel 13 is performed. do.

In addition, the solar power monitoring module 33 monitors the state of charge of the conditioner battery 14 with the power of the solar cell panel 13, and the engine power generation monitoring module 34 monitors the power generated by the engine generator 11. , the conditioner battery charge monitoring step (S2) of monitoring the state of charge of the conditioner battery 14 is performed.

As described above, the cooling and heating operation is performed in a state in which the conditioner battery 14 of the parking air conditioner 20 has a sufficient remaining charge, and the user operates the parking air conditioner 20 under the control of the main controller 31 The parking air conditioner operation step (S3) is performed.

In addition, the cooling/heating operation termination step (S5) of stopping the operation of the parking air conditioner 20 by the control of the main controller 31 by the user's operation is performed. Furthermore, as will be described later, the cooling/heating operation may be terminated when the remaining battery power is insufficient or depending on the external environment.

In other words, the heating/cooling driving enable determining unit 50 determines the remaining charge of the vehicle battery 12 and the conditioner battery 14 and transmits information about stopping the cooling/heating operation to the main controller 31 .

In addition, during the cooling/heating operation of the parking air conditioner 20 for cooling/heating operated by the parking air conditioner operation step (S3), the charging power of the conditioner battery 14 and the vehicle battery 12 is determined by the cooling/heating drive availability determination unit 50. is determined, and when the remaining charge amount is less than or equal to each remaining charge value stored in the memory 32, a cooling/heating driving enable determination step (S4) of transmitting determination information of stop to the main controller 31 is further performed.

In this way, when sufficient charging power to operate the parking air conditioner 20 for cooling and heating operation is insufficient, the operation of the parking air conditioner 20 may be stopped for stable operation of the vehicle.

In particular, in the case of a commercial vehicle, a driving motor is operated to operate again after parking or stopping, and in this case, considerable charging power is required to drive the driving motor. Therefore, sufficient charging power is required, and for this purpose, by determining whether the charging power is sufficient during operation of the parking air conditioner 20, driving for commercial vehicles is stably performed.

Accordingly, looking at the detailed configuration of the heating/cooling driving availability determining unit 50, sensing information is received from the conditioner battery power sensing unit 42 that has sensed the charging power of the conditioner battery 14, and the charging power of the conditioner battery 14 is determined. A conditioner battery driving discrimination unit 51 for analysis is provided.

The conditioner battery driving discrimination unit 51 includes a conditioner battery remaining charge analysis module 511 that analyzes the remaining charge of the conditioner battery 14 .

and a conditioner battery remaining charge driving determination module 512 that compares the remaining charge amount analyzed by the conditioner battery charge amount analysis module 511 with a set value of the conditioner charge remaining charge amount stored in the memory 32 . Thus, the remaining charge amount of the conditioner battery is determined.

In addition, a vehicle battery driving determination unit 52 is provided to receive sensing information from the vehicle battery power sensing unit 41 that senses the charging power of the vehicle battery 12 and analyze the charging power of the vehicle battery 12 .

The vehicle battery driving determination unit 52 includes a vehicle battery charge analysis module 521 that analyzes the charge remaining amount of the vehicle battery 12 .

And a vehicle battery operation determination module 522 that compares the remaining charge amount analyzed by the vehicle battery charge amount analysis module 521 with a set value of the remaining charge amount of the vehicle battery 12 stored in the memory 32. Thus, the remaining charge of the vehicle battery 12 can be checked.

In the heating/cooling operation capability determination step (S4) by the vehicle battery operation determination unit 52, the conditioner battery operation received sensing information from the conditioner battery power sensing unit 42 that senses the charged power of the conditioner battery 14. The vehicle battery drive discrimination unit that analyzes the charging power of the conditioner battery 14 by the determining unit 51 and receives the sensing information from the vehicle battery power sensing unit 41 that senses the charging power of the vehicle battery 12 ( 52), the charging power of the vehicle battery 12 is analyzed, and the remaining battery capacity driving determination step (S41) of comparing and discriminating with each charging power stored in the memory 32 is performed.

As such, the remaining charge of the vehicle battery 12 and the remaining charge of the conditioner battery 14 are analyzed.

Accordingly, in the battery remaining amount driving determining step (S41), the remaining charged amount of the conditioner battery 14 is analyzed by the conditioner battery remaining charged amount analysis module 511 of the conditioner battery driving determining unit 51, and the conditioner battery remaining amount driving determining module In step 512, the conditioner battery residual amount determination step (S411) of comparing the remaining charged amount of the conditioner stored in the memory 32 is performed. Thus, the remaining charge amount of the conditioner battery is determined.

In addition, the remaining charge of the vehicle battery 12 is analyzed by the vehicle battery driving determination analysis module 521 of the vehicle battery driving determination unit 52, and the vehicle stored in the memory 32 by the vehicle battery driving determination module 522. A vehicle battery residual amount determination step (S412) of comparing the remaining charged amount of the battery 12 with the set value is performed. Thus, the remaining charge of the vehicle battery 12 can be checked.

Accordingly, when the remaining charge is insufficient by comparison with the set value of the remaining charge of the conditioner battery 14 and the vehicle battery 12 in the conditioner battery remaining amount determining step (S411) and vehicle battery remaining amount determining step (S412), the parking air conditioner 20 ) is to perform the battery basic residual amount drive determination step (S413) of transmitting information for stopping the cooling and heating operation to the main controller 31 side. Thus, when charging power such as the conditioner battery 14 and the vehicle battery 12 is insufficient, the cooling and heating operation of the parking air conditioner 20 is stopped under the control of the main controller 31 .

Next, in driving the air conditioner, the charging power of the conditioner battery 14 is first determined, and the parking air conditioner 20 can be operated with the power of the conditioner battery 14. After that, in continuously operating the parking air conditioner 20, it is driven by the charging power of the vehicle battery 12. In this case, when all of the power of the vehicle battery 12 is used, it may be difficult to operate the driving motor for subsequent engine driving. Therefore, the remaining charging power of the vehicle battery 12 should remain charging power enough to drive the driving motor.

In this case, the state of charge of the battery or the charging and discharging operation of the battery is closely related to the temperature of the battery and the temperature of the outside. In general, when the external temperature is extremely low, the battery power may be insufficient, such as low charging efficiency. Conversely, when charging and discharging occurs in an extremely high temperature state, internal components may be damaged. Therefore, when the external environment is in an extreme temperature situation, it will be necessary to stop the operation of the parking air conditioner 20 in order to operate the commercial vehicle. Let's take a look at the configurations for this.

That is, an external temperature driving discrimination unit 53 is provided to compare and determine the external temperature set value stored in the memory 32 and the sensed external temperature with respect to the external temperature information received from the external temperature sensing unit 43. .

Therefore, in the heating/cooling driving possibility determination step (S4), the external temperature driving determination unit 53 stores the driveable external temperature set value in the memory 32 with respect to the external temperature information received from the external temperature sensing unit 43. , an outdoor temperature sensing and determination step (S42) of comparing and determining the sensed external temperature is performed.

In the outside temperature sensing and determination step (S42), the outside temperature sensing step (S421) of sensing the outside temperature by the outside temperature sensing unit 43 is performed, and the outside temperature sensed by the outside temperature sensing unit 43 is performed. The external temperature drive determination unit 53 that receives the information compares and determines the driveable external temperature set value stored in the memory 32 with the sensed external temperature and transmits it to the main controller 31, and the external temperature is the external temperature When it is determined that the extreme temperature range is out of the set range, an outdoor temperature operating range determination step (S422) of transmitting information for stopping the heating and cooling operation to the main controller 31 is performed.

Furthermore, when the external temperature is out of the extreme temperature range, it includes an extreme temperature remaining amount drive determination unit 54 that transmits information for stopping the cooling and heating operation of the parking air conditioner 20 to the main controller 31 side.

Accordingly, in the heating/cooling driving possibility determining step (S4), when the external temperature is out of the extreme temperature range by the extreme temperature residual amount driving determining unit 54, information for stopping the cooling/heating operation of the parking air conditioner 20 is transmitted to the main controller 31 ) is to perform the vehicle battery extreme remaining amount driving determination step (S43) transmitted to the side.

When the external temperature is lower than the cryogenic temperature set value stored in the memory 32, in the extreme temperature remaining amount drive determination unit 54, the set value of the cryogenic charge remaining amount corresponding to the cryogenic temperature and the charge of the vehicle battery 12 A vehicle battery cryogenic drive determination module 541 that compares and discriminates the remaining amount and transmits discrimination information on whether the main controller 31 stops heating or cooling operation when the remaining charge amount of the vehicle battery 12 is less than or equal to the set value of the cryogenic charge remaining amount.

Accordingly, in the vehicle battery extreme remaining amount driving determination step (S43), the external temperature is lower than the cryogenic temperature set value stored in the memory 32 by the vehicle battery cryogenic driving determination module 541 of the extreme temperature remaining amount driving determination unit 54. In the case of temperature, the set value of the cryogenic charge remaining amount corresponding to the cryogenic temperature and the remaining charge amount of the vehicle battery 12 are compared and determined, and if the remaining charge amount of the vehicle battery 12 is less than the set value of the cryogenic charge remaining amount, the main controller 31 A vehicle battery cryogenic driving determination step (S431) of transmitting determination information on the suspension of cooling and heating operation is performed.

Therefore, when the external temperature is at a cryogenic temperature, the cryogenic charge remaining amount setting value, which is the remaining charge amount setting value for the vehicle battery 12 stored in the memory 32 when the temperature is at a cryogenic temperature, and the sensed charge amount of the vehicle battery 12 Compared to the cryogenic charge remaining amount is less than the set value, the operation of the parking air conditioner 20 can be stopped by the control of the main controller 31.

Accordingly, the cryogenic temperature range can be set to about -13 ° C to -16 ° C, as shown in the examples of FIGS. will be able to be carried out In addition, the cryogenic temperature range is also a temperature range described for explanation in FIGS. 9 and 10, etc., and the cryogenic temperature range actually applied is appropriately determined according to the usage environment such as specifications of commercial vehicles, performance and capacity of batteries. Can be implemented.

In addition, when the external temperature is higher than the extreme high temperature set value stored in the memory 32, the extreme temperature residual amount driving determination unit 54 determines the value of the extremely high temperature remaining charge amount corresponding to the extremely high temperature and the vehicle battery 12 The vehicle battery extreme high temperature drive determination module 542 that compares and discriminates the remaining charge amount and transmits determination information of the cooling and heating operation stop of the main controller 31 when the remaining charge amount of the vehicle battery 12 is less than the set value of the extreme high temperature charge amount to include

Accordingly, in the vehicle battery extreme remaining amount driving determination step (S43), the external temperature is the extremely high temperature set value stored in the memory 32 by the vehicle battery extremely high temperature driving determination module 542 of the extreme temperature remaining amount driving determination unit 54 In the case of a higher temperature, the set value of the extremely high temperature remaining charge amount corresponding to the extremely high temperature and the remaining charge amount of the vehicle battery 12 are compared and determined, and when the remaining charge amount of the vehicle battery 12 is less than the set value of the extremely high temperature remaining charge amount The main controller 31 performs the vehicle battery extreme high temperature driving determination step (S432) of transmitting the determination information of the cooling/heating operation stop.

Therefore, when the external temperature is extremely high, the set value of the remaining charge amount of the vehicle battery 12 stored in the memory 32, which is the remaining charge amount set value when the temperature is extremely high, and the sensed vehicle battery 12 The operation of the parking air conditioner 20 may be stopped by the control of the main controller 31 when the remaining charge amount of the electric charge is compared and becomes equal to or greater than the set value of the remaining charge amount at extremely high temperature.

Accordingly, the extreme high temperature temperature range may be set to approximately 40 ° C to 45 ° C, as shown in the examples of FIGS. will be able to be carried out In addition, the extremely high temperature range is also a temperature range described for explanation in FIGS. 9 and 10, and the extremely high temperature range that is actually applied can be appropriately determined and implemented according to the usage environment such as specifications of commercial vehicles, performance and capacity of batteries. will be.

Next, the cooling/heating driving availability determining unit 50 provides information for stopping the cooling/heating operation of the parking air conditioner 20 when the external temperature is out of the set value range of the extremely low temperature or the extremely high temperature by the extreme temperature remaining amount driving determining unit 54. is received from the main controller 31, by the dim driving discrimination unit 55 receiving the control signal from the main controller 31, the heating and cooling operation is performed during the operation time of the predetermined dim operation set value stored in the memory 32 A dim driving discriminating unit 55 for discriminating may be further included.

Accordingly, in the heating/cooling driving capability determining step (S4), the vehicle battery extreme residual amount driving determining step (S43) provides information for stopping the cooling and heating operation of the parking air conditioner 20 when the external temperature is out of the set value range of the extremely low temperature or extremely high temperature. is received from the main controller 31, by the dim driving discrimination unit 55 receiving the control signal from the main controller 31, the heating and cooling operation is performed during the operation time of the predetermined dim operation set value stored in the memory 32 A vehicle battery dim operation determination step (S44) of determining the may be further performed.

That is, according to the dim driving discrimination unit 55, as described above, when the external temperature environment is determined to be extremely low temperature or extremely high temperature, the operation of the parking air conditioner 20 can be stopped by the control of the main controller 31 Before the parking air conditioner 20 completely stops, if the external temperature range is in the temperature range set for the dimming operation, the dimming operation is performed so that the parking air conditioner 20 is briefly operated for a predetermined dimming time. it is to lose As a result, the parking air conditioner 20 gradually stops the heating and cooling operation so that the driving of each member is stably performed, and the user will also be able to cope while examining the situation.

Looking at the detailed configuration of the dim driving discrimination unit 55, the dim driving charging power set value stored in the memory 32 is read, and the vehicle battery dim driving residual power for comparison and analysis with the remaining charge of the vehicle battery 12 An analysis module 551 is included.

Accordingly, in the vehicle battery dim operation discrimination step (S44), the vehicle battery dim driving residual power analysis module 551 of the dim driving discrimination unit 55 reads the dim driving charging power set value stored in the memory 32, , A vehicle battery dim operation power analysis step (S441) of comparing and analyzing the remaining charge of the vehicle battery 12 is performed.

In addition, the dim driving discrimination unit 55 determines whether the remaining charge of the vehicle battery 12 is in the range of the dim driving low temperature charging amount and the cryogenic charging remaining amount of the dim driving charging power setting value in the case of an extremely low temperature state, or in the extremely high temperature state. Vehicle battery dim driving discrimination module (552) that transmits information on the continuous driving of the cooling and heating operation of the parking air conditioner (20) to the main controller (31) side when the remaining dim driving high temperature charging amount and the extreme high temperature charging remaining amount of the charging power setting value are in the range ) is included.

Accordingly, in the vehicle battery dim operation discrimination step (S44), by the vehicle battery dim driving discrimination module 552 of the dim driving discrimination unit 55, when the remaining charge of the vehicle battery 12 is in a cryogenic state, dim driving charging Cooling and heating of the parking air conditioner (20) when it is within the range of the dim drive low-temperature charge remaining amount and the cryogenic charge remaining amount of the power setting value, or in the case of an extremely high temperature state, in the case of the dim driving high-temperature charge remaining amount and the extreme high-temperature charge remaining amount of the dim driving charging power setting value The vehicle battery dim driving determination step (S442) of transmitting information on continuous operation to the main controller 31 is performed.

The cryogenic dimming operating temperature range and the ultra-high temperature dimming operating temperature range for dim driving may be generally set to -3°C, +3°C, or the like, as in the example of FIG. 10 . In addition, the dimming operating temperature range may be determined and implemented depending on the composition of the commercial vehicle's engine, battery, and the like, and the use environment.
