The invention provides a parking air conditioner control method. The control method may be used for a ceiling-mounted parking air conditioner. Such as an overhead integrated parking air conditioner.
Fig. 1 is a method schematic diagram of an embodiment of a parking air conditioner control method provided by the invention.
As shown in fig. 1, according to an embodiment of the present invention, the control method includes at least step S110, step S120, and step S130.
And step S110, when the parking air conditioner receives a starting signal, determining whether to start the parking air conditioner according to the voltage of the storage battery and the ambient temperature outside the automobile.
Specifically, whether the battery voltage Dj is less than or equal to a set highest starting operation voltage Dh and greater than or equal to a set lowest protection voltage Ds, and whether the vehicle exterior environment temperature T1 is less than or equal to a set highest air conditioner operation temperature Th and greater than or equal to a set lowest air conditioner operation temperature Td is determined; and if the storage battery voltage Dj is judged to be less than or equal to the set highest starting operation voltage Dh and greater than or equal to the set lowest protection voltage Ds, and the external environment temperature T1 is less than or equal to the set air conditioner operation highest temperature Th and greater than or equal to the set air conditioner operation lowest temperature Td, determining to start the parking air conditioner.
For example, when the parking air conditioner receives a starting signal, the storage battery voltage Dj is detected, whether the storage battery voltage Dj is between the highest starting operation voltage Dh and the set lowest protection voltage Ds is judged, namely whether Dh is larger than or equal to Dj and larger than or equal to Ds is judged, and if not, the parking air conditioner is determined not to be started. If Dh is larger than or equal to Dj and larger than or equal to Ds, the parking air conditioner control system detects the outer ring temperature T1, judges whether the outer ring temperature T1 is between the highest air conditioner operation temperature Th and the lowest air conditioner operation temperature Td, namely judges whether Td is larger than or equal to T1 and smaller than or equal to Th, if yes, the parking air conditioner is determined to be started, and if not, the parking air conditioner is determined not to be started.
Wherein, the value range of the highest starting operation voltage Dh includes: greater than 27V and less than 32V, the minimum protection voltage Ds has a value range including: greater than 21.5V and less than 23.5V.
And step S120, if the parking air conditioner is determined to be started, determining to start an air supply mode or a refrigeration mode according to a first operation mode setting command or the current environment temperature in the vehicle.
In one embodiment, the air supply mode or the cooling mode is determined to be started according to the first operation mode setting command, that is, the air supply mode or the cooling mode is determined to be started according to a preset operation mode or an operation mode set after the power is turned on, for example, a user manually sets the air supply mode or the cooling mode in advance or manually sets the air supply mode or the cooling mode after the power is turned on.
In one embodiment, determining to start the air supply mode or the cooling mode according to the current ambient temperature in the vehicle may specifically include: and judging whether the current environment temperature in the vehicle is greater than the difference between the current set temperature and the preset judgment temperature difference, if so, determining to start the refrigeration mode, and otherwise, determining to start the air supply mode. For example, when the current inner ring temperature Tz is greater than the set temperature Tm minus the judgment temperature difference Tv (Tz is greater than Tm minus Tv), the cooling mode is operated, otherwise, the air supply mode is operated, and the range of the judgment temperature difference Tv is, for example, greater than or equal to 0 ℃ and less than or equal to 2 ℃.
And step S130, if the refrigeration mode is determined to be started, controlling the parking air conditioner to enter a secondary operation mode for operation in the refrigeration mode according to a second operation mode setting command or the current temperature of the environment outside the vehicle.
Specifically, if the air supply mode is determined to be started, the operation of the inner fan of the air conditioner is controlled. And if the refrigeration mode is determined to be started, controlling the parking air conditioner to enter a secondary operation mode to operate in the refrigeration mode according to a second operation mode setting command or the current environment temperature outside the vehicle. In a specific embodiment, the parking air conditioner is controlled to enter the secondary operation mode operation in the cooling mode according to the second operation mode setting command, that is, the started secondary operation mode is determined according to the preset or post-startup set secondary operation mode, for example, the user manually sets the started secondary operation mode in advance or manually sets the started secondary operation mode after startup.
In one embodiment, the secondary operating mode comprises: a free running mode and a set running mode. The free running mode comprises the step of controlling the air conditioner to run according to set logic. Specifically, in the free running mode, the operation of the parking air conditioner is controlled according to an environmental parameter and/or an operation parameter. Including, for example, shutdown when the vehicle interior temperature reaches a temperature point, down-scaling of various functional protection limits (e.g., freeze protection, power, current, etc.), and/or compressor operating frequency controlled by a fuzzy algorithm. Optionally, the secondary operating mode may further include an energy saving mode and a power mode.

Namely, different temperature intervals are preset to respectively correspond to different secondary operation modes.
For example, when the ambient temperature outside the vehicle is less than or equal to Tx (namely Tx is an energy-saving mode determination value), the vehicle enters an energy-saving mode, and the value range of Tx can be set between 27 ℃ and 20 ℃; when the temperature outside the vehicle environment is greater than or equal to Tz (Tz is a strong mode judgment value), entering a strong mode, wherein the value range of Tz can be set between 45 and 52 ℃; the free running mode is entered when the outside ambient temperature is greater than Tx but less than Tz.
In one embodiment, the controlling the parking air conditioner to enter the set operation mode operation in the cooling mode may specifically include: the air outlet area of the air outlet is reduced, the air speed of the air outlet is improved, and/or the air outlet angle is adjusted so that the air outlet direction faces a user. The air outlet area is reduced, for example, one or more air outlets are closed or the angle of an air outlet grille is adjusted, for example, the air outlet grille is changed from vertical downward to inclined downward, and the air is blown to a user or a nearby space.
The set operation mode is specifically a cold feeling mode, and the principle of the cold feeling mode is that the air outlet area is reduced, the air speed of the air outlet is increased, the air supply distance is increased, the air outlet diffusivity is reduced, and the air outlet temperature is reduced so as to achieve the purpose of cooling in a specific area, so that when the parking air conditioner is just started (the temperature in a vehicle is higher) or the temperature in the vehicle cannot be reduced in a short time, the body surface of a user can be cooled, and the user experience degree is improved.
When the set operation mode is operated, if a user presses any key of a controller (such as a remote controller), the set operation mode is exited, and the free operation mode is entered for operation.

Specifically, whether the running time of the refrigeration free running mode reaches the set running time ty is detected, if so, the current inner ring temperature Tp and the inner ring temperature (the temperature detected for the first time as the starting time of the free running mode) To detected in the last period are detected, and judgment is carried out, if the current inner ring temperature Tp is detected To be larger than or equal To the detected inner ring temperature To in the last period and the temperature difference Tj (the first set temperature difference) needs To be reduced is set, if not, the next period is judged, if so, the current inner ring temperature Tp and the current set temperature Ts are detected To be judged, if the current inner ring temperature Tp is larger than the current set temperature Ts and the set temperature difference Tc is detected To be set, the cold feeling mode is determined, and if not, the next period is judged. Setting the value range of the operating time ty comprises: more than 30min and less than 90min, the value range of the first set temperature difference tj comprises: greater than 2 ℃ and less than 5 ℃, the second set temperature difference tc comprises: greater than 7 ℃ and less than 14 ℃.
