- the temperature outside the car is high (for example, 38°C).
- the temperature inside the car is controlled to be lowered, the heat outside the car is quickly transferred to the inside of the car through the car body.
- the temperature outside the car is low (for example, 5°C).
- the temperature inside the car is controlled to be raised, the heat inside the car is quickly dissipated to the outside of the car through the car body.
- the first threshold is 10° C. + the compensation temperature
- the second threshold is 1° C. + the compensation temperature
- the first threshold and the second threshold may be determined according to the type of RV.
- the temperature sensor in the car is affected by the evaporator in the car, resulting in the in-car temperature acquisition not accurately reflecting the actual temperature in the car, affecting the precise control of the air conditioner temperature, thus affecting comfort.

- the air conditioner When the ambient temperature is low, the heat transfer rate between the inside and outside of the vehicle is low, so there is no need to run the air conditioner in high-power mode.
- the temperature inside the RV can be precisely controlled according to the preset mode. And when running in preset mode, the air conditioner has lower energy consumption, which helps save the RV’s energy and improves its endurance.
- the air conditioner includes at least a first energy-saving mode, a second energy-saving mode and a strong mode; in the first energy-saving mode, the compressor frequency is a first frequency, the indoor unit wind speed is a first wind speed, and the working current is a first current; in the second energy-saving mode, the compressor frequency is a second frequency, the indoor unit wind speed is a second wind speed, and the working current is a second current; in the strong mode, the compressor frequency is a third frequency, the indoor unit wind speed is a third wind speed, and the working current is a third current; and, the second frequency, the first frequency, and the third frequency increase successively, the second current, the first current, and the third current increase successively, and the second wind speed, the first wind speed, and the third wind speed increase successively.
- the first current is 75% of the third current

- the high-power mode runs, the temperature inside the vehicle changes and gradually approaches the set temperature. At this time, the operating power of the air conditioner can be appropriately reduced to save energy.
- the air conditioner When the air conditioner is running, the temperature inside the car decreases. When the absolute value of the difference between the temperature inside the car and the set temperature (including heating and cooling) is less than the third threshold, the operating power of the air conditioner can be appropriately reduced.

- the third threshold is 1°C + compensation temperature
- the second preset time is 15 minutes. That is, 15 minutes after switching to the second energy-saving mode, the temperature in the car changes rapidly, and the second energy-saving mode does not meet the cooling/heating needs in the RV.
- the step of running the air conditioner in the second energy-saving mode further includes:
- S1115. Determine that the absolute value of the temperature difference between the vehicle interior temperature and the set temperature is greater than a third threshold value, and the air conditioner runs in the second energy-saving mode for a duration greater than a third preset duration, then the air conditioner runs in the first energy-saving mode for a fourth preset duration and then switches to the second energy-saving mode.

相关技术中，房车的保温及防晒措施一般，在环境温度较高时，房车若在户外放置的时间较久，会导致房车内温度远大于环境温度，且车内外温度传递速率较高。在这种情况下，单纯靠室温传感器来判定运行逻辑，不能满足目前的需求。
根据本申请第一方面实施例提供的房车空调的控制方法，请参阅图1，包括：
S100、获取车内温度和车外温度；
S110、根据车内温度与车外温度确定房车内的环境状态，并根据环境状态调整空调器的工作模式。
可以理解的是，空调器包括室内机和室外机，可以通过室内机自带的温度传感器获取车内温度，通过室外机自带的温度传感器获取车外温度，也可以设置独立的车内温度传感器和车外温度传感器，其中车内温度传感器与车外温度传感器均信号连接于空调器的控制单元。
需要说明的是，用于检测车外温度的传感器需要避免与车体的外壳直接接触，避免造成温度检测误差较大。例如，在炎炎夏日，车外环境温度35℃，车体外壳的温度可能达到50℃以上，与实际环境温度的差距较大，对空调器的运行也会带来较大的影响。
房车处于室外时，基于房车的保温及防晒措施，车内外的热量交换较快，如果空调器根据车内温度并按照以往的控制逻辑运行，难以平衡车内外热量交换的这一部分热量，导致车内始终无法达到预设温度，严重影响用户的使用体验。
根据本申请实施例提供的房车空调的控制方法，在调整空调器的运行模式时，不仅考虑了车内温度的影响，还考虑了车内温度与车外温度的温差对热量传递速率的影响，根据车内温度与车外温度确定房车内的环境状态，然后根据环境状态确定空调器的工作模式。
空调器运行时，根据环境状态调整房车空调的运行模式，不仅可以快速调节房车内的温度，提高用户的舒适度，还有利于节省空调器的能耗。
需要说明的是，与一般的家用空调相比，房间的混凝土结构与房车的壳体(多为金属)结构有着较大的区别，在保温性能、防晒性能以及热传递性能方面的区别较大，因此家用空调的控制逻辑不能简单适用于房车空调。
根据本申请的一个实施例，根据车内温度与车外温度确定房车内的环境状态的步骤，具体包括：
S111、确定车内温度与车外温度的差值的绝对值大于第一阈值，则环境状态为高温差状态；
S112、确定车内温度与车外温度的差值的绝对值介于第一阈值和第二阈值之间，则环境状态为中温差状态；
S113、确定车内温度与车外温度的差值的绝对值小于第二阈值，则环境状态为低温差状态。
可以理解的是，在车内温度与车外温度的差值较大时，房车的车内外热量传递速率较高，环境状态确定为高温差状态；在车内温度与车外温度的差值较小时，房车的车内外热量传递速率较低，环境状态确定为低温差状态。
需要说明的是，实际使用时存在制热与制冷两种情况：在第一种情况下，车外温度较高(例如38℃)，控制车内温度降温时，车外的热量通过车体快速传递至车内；在第二种情况下，车外温度较低(例如5℃)，控制车内温度升高时，车内的热量通过车体快速散发至车外。根据上述内容可
知，基于房车的保温及防晒措施，车内温度与车外温度的差值的绝对值对房车内的环境状态有着直接的影响。
车内温度与车外温度的差值的绝对值较大时，车内外热量传递速率较高，需要增加空调器的运行功率。与此同时，阈值的设定还需要考虑到车体自身的热量传递情况。
在一些情况下，第一阈值为10℃+补偿温度，第二阈值为1℃+补偿温度。
在其它的情况下，第一阈值和第二阈值可以根据房车的类型确定。
在制冷或制热模式下，由于车内温度场分布不均匀，上部温度较高，下部温度较低，同时车内温度传感器受到车内蒸发器的影响，导致车内温度采集不能准确反映实际车内温度，影响空调器温度的精确控制，从而影响舒适性。为改善上述问题，通常会对车内环境温度进行补偿，利用补偿后的环境温度值对空调器的运行过程进行控制。温度补偿值是事先固化在存储器里，不同区域或相同区域的不同用户，可能对温度感受不同，可以根据需要更改此值。
根据本申请的一个实施例，根据环境状态调整空调器的工作模式的步骤，具体包括：
S1110、确定环境状态为高温差状态，空调器运行强力模式；
S1120、确定环境状态为中温差状态，空调器启动时运行强力模式，且逐渐降频至预设模式；
S1130、确定环境状态为低温差状态，空调器运行预设模式。
可以理解的是，在环境状态为高温差状态时，车体内外的热量传递速率较高，此时空调器运行强力模式，空调器的压缩机高频运行，室内风机强力运行，有助于快速改善车内温度，同时还可以抵消车内外温差带来的影响。
在环境状态为中温差状态时，车体内外的热量传递速率相对较高，此时空调器启动时运行强力模式，然后逐渐降低至预设模式，不仅可以快速改善车内温度，还可以适当抵消车内外温差带来的影响。
在环境状态为低温差状态时，车体内外的热量传递速率较低，空调器没必要运行强力模式，按照预设模式就可以实现房车内温度的精准控制，
且按照预设模式运行，空调器的能耗较低，有利于节约房车的能源，提升续航能力。
根据本申请实施例提供的房车空调的控制方法，空调器至少包括第一节能模式、第二节能模式和强力模式；在第一节能模式，压缩机频率为第一频率，室内机风速为第一风速，工作电流为第一电流；在第二节能模式，压缩机频率为第二频率，室内机风速为第二风速，工作电流为第二电流；在强力模式，压缩机频率为第三频率，室内机风速为第三风速，工作电流为第三电流；而且，第二频率、第一频率、第三频率依次增大，第二电流、第一电流、第三电流依次增大，第二风速、第一风速、第三风速依次增大。
在一些实施例中，第一电流为第三电流的75％，第二电流为第三电流的50％。
当然，空调器还包括其它各种模式，可以在接收用户的指令后，运行强力模式、第一节能模式、第二节能模式或者预设模式等。
根据本申请的一个实施例，确定环境状态为高温差状态，空调器运行强力模式的步骤，之后还包括：
S1111、持续获取车内温度；
S1112、确定车内温度与设定温度的温差的绝对值小于第三阈值时，空调器运行第一节能模式。
可以理解的是，在环境状态为高温差状态时，车体内外的热量传递速率较高，此时空调器运行强力模式，空调器的压缩机高频运行，室内风机强力运行，有助于快速改善车内温度，同时还可以抵消车内外温差带来的影响。随着强力模式的运行，车内温度改变，逐渐接近设定温度，此时可以适当降低空调器的运行功率，节省能耗。
空调器运行时，车内温度降低，车内温度与设定温度的差值的绝对值(包括制热与制冷两种情况)小于第三阈值时，可以适当降低空调器的运行功率，此时以第一节能模式运行，空调器的压缩机功率、工作电流以及室内机风速均降低，有利于节约房车的能耗，提升续航能力。
根据本申请的一个实施例，空调器运行第一节能模式的步骤之后，还包括：
S1113、确定空调器运行第一节能模式的时长大于第一预设时长，则空
调器运行第二节能模式。
可以理解的是，在第二节能模式下，空调器的压缩机功率、工作电流以及室内机风速进一步降低，有利于节约房车的能耗。
根据本申请的一个实施例，确定空调器运行第一节能模式的时长大于第一预设时长，则空调器运行第二节能模式的步骤，之后还包括：
S1114、确定车内温度与设定温度的温差的绝对值大于第三阈值，且空调器运行第二节能模式的时长小于第二预设时长，则空调器运行第一节能模式。
可以理解的是，在空调器运行强力模式后，房车内的温度快速降低。空调器在强力模式下的制冷/制热功率大于房车内外的热量传递速率，因此可以切换至第一节能模式。
为了进一步降低房车的能耗，空调器在运行第一节能模式之后，可以进一步切换至第二节能模式，依次类推，可以找到一个合适的节能模式，在该节能模式下，空调器的制冷/制热功率与房车内外的热量传递速率保持平衡，此时不仅能保持车内温度，还可以处于最佳的节能状态。
在空调器切换至第二节能模式时，空调器的制热/制冷功率可能小于房车内外的热量传递速率，空调器运行第二节能模式时，车内温度逐渐远离设定温度，例如大于第三阈值，此时需要将空调器切换至第一节能模式，以维持房车内的温度稳定。
在一些实施例中，第三阈值为1℃+补偿温度，第二预设时长为15分钟，即切换至第二节能模式15分钟之后，车内迅速发生温度改变，第二节能模式不满足房车内制冷/制热需求。
根据本申请的一个实施例，确定空调器运行第一节能模式的时长大于第一预设时长，则空调器运行第二节能模式的步骤，之后还包括：
S1115、确定车内温度与设定温度的温差的绝对值大于第三阈值，且空调器运行第二节能模式的时长大于第三预设时长，则空调器以第一节能模式运行第四预设时长后切换至第二节能模式。
可以理解的是，在空调器切换至第二节能模式，且以第二模式运行的时长超过第三预设时长之后，说明空调器在第二节能模式下的制热/制冷功率与房车内外的热量传递速率很接近，在较长的时间内车内温度才会出现
变化。车内温度与设定温度的温差的绝对值大于第三阈值时，空调器切换至第一节能模式，用以及时调节车内温度。空调器以第一节能模式运行第四预设时长之后，再次切换至第二节能模式，用于尽可能地节约房车的能耗，且在第二节能模式下，房车内的温度也不会发生较大的变化。
在一些实施例中，第三预设时长为1小时，第四预设时长为1小时。
根据本申请第二方面实施例提供的房车空调的控制装置，请参阅图2，包括：
获取模块200，用于获取车内温度和车外温度；
控制模块201，用于根据车内温度与车外温度确定房车内的环境状态，并根据环境状态调整空调器的工作模式。
