Furthermore, the different embodiments or examples described in this specification and the features of the different embodiments or examples may be combined and combined by those skilled in the art without contradiction.
In the related art, the heat preservation and sun protection measures of the caravan are common, when the ambient temperature is higher, if the caravan is placed outdoors for a long time, the temperature in the caravan is far higher than the ambient temperature, and the temperature transfer rate inside and outside the caravan is higher. In this case, the operating logic is determined simply by the room temperature sensor, and the current demand cannot be satisfied.
Referring to fig. 1, a method for controlling an air conditioner of a motor home according to an embodiment of the first aspect of the present invention includes:
s100, acquiring the temperature in the vehicle and the temperature outside the vehicle;
s110, determining the environmental state in the motor home according to the temperature in the motor home and the temperature outside the motor home, and adjusting the working mode of the air conditioner according to the environmental state.
It can be understood that the air conditioner comprises an indoor unit and an outdoor unit, the temperature in the vehicle can be obtained through the temperature sensor of the indoor unit, the temperature outside the vehicle can be obtained through the temperature sensor of the outdoor unit, and the independent temperature sensor in the vehicle and the independent temperature sensor outside the vehicle can be arranged, wherein the temperature sensor in the vehicle and the temperature sensor outside the vehicle are respectively connected with a control unit of the air conditioner through signals.
The sensor for detecting the temperature outside the vehicle needs to avoid direct contact with the housing of the vehicle body, and avoid causing a large temperature detection error. For example, in hot summer, the temperature of the outside environment of the vehicle may reach more than 50 ℃ and the temperature of the vehicle body shell may be greatly different from the actual environment temperature, which may also have a great influence on the operation of the air conditioner.
When the motor home is outdoors, based on heat preservation and sun protection measures of the motor home, heat exchange between the interior and the exterior of the motor home is quicker, and if the air conditioner operates according to the temperature in the motor home and the control logic in the past, the heat exchanged between the interior and the exterior of the motor home is difficult to balance, so that the interior of the motor home can not reach the preset temperature all the time, and the use experience of a user is seriously affected.
According to the control method of the air conditioner of the motor home, when the operation mode of the air conditioner is adjusted, the influence of the temperature in the motor home is considered, the influence of the temperature difference between the temperature in the motor home and the temperature outside the motor home on the heat transfer rate is considered, the environmental state in the motor home is determined according to the temperature in the motor home and the temperature outside the motor home, and then the operation mode of the air conditioner is determined according to the environmental state.
When the air conditioner operates, the operation mode of the air conditioner of the motor home is adjusted according to the environment state, so that the temperature in the motor home can be quickly adjusted, the comfort level of a user is improved, and the energy consumption of the air conditioner is saved.
It should be noted that, compared with a general household air conditioner, the concrete structure of the room is greatly different from the shell (most of metal) structure of the caravan, and the difference in terms of heat preservation performance, sun protection performance and heat transfer performance is large, so that the control logic of the household air conditioner cannot be simply applied to the caravan air conditioner.
According to one embodiment of the invention, the step of determining the environmental state in the motor home according to the temperature in the motor home and the temperature outside the motor home specifically comprises the following steps:
s111, determining that the absolute value of the difference value between the temperature in the vehicle and the temperature outside the vehicle is larger than a first threshold value, and the environment state is a high temperature difference state;
s112, determining that the absolute value of the difference value between the temperature in the vehicle and the temperature outside the vehicle is between a first threshold value and a second threshold value, and the environment state is a medium temperature difference state;
and S113, determining that the absolute value of the difference value between the temperature in the vehicle and the temperature outside the vehicle is smaller than a second threshold value, and the environment state is a low temperature difference state.
It can be understood that when the difference between the temperature in the car and the temperature outside the car is large, the heat transfer rate between the inside and the outside of the car is high, and the environmental state is determined as a high temperature difference state; when the difference between the temperature in the car and the temperature outside the car is smaller, the heat transfer rate inside and outside the car is lower, and the environment state is determined to be a low temperature difference state.
It should be noted that, during actual use, there are two situations of heating and cooling: in the first case, the temperature outside the vehicle is higher (for example, 38 ℃), and when the temperature in the vehicle is controlled to be reduced, the heat outside the vehicle is quickly transferred into the vehicle through the vehicle body; in the second case, the temperature outside the vehicle is low (e.g., 5 ℃), and when the temperature inside the vehicle is controlled to rise, the heat inside the vehicle is rapidly dissipated outside the vehicle through the vehicle body. According to the above, based on the measures of heat preservation and sun protection of the motor home, the absolute value of the difference between the temperature inside the motor home and the temperature outside the motor home has a direct influence on the environmental state inside the motor home.
When the absolute value of the difference between the temperature inside the vehicle and the temperature outside the vehicle is large, the heat transfer rate inside and outside the vehicle is high, and the operation power of the air conditioner needs to be increased. At the same time, the threshold value is set in consideration of the heat transfer condition of the vehicle body itself.
In some cases, the first threshold is 10°c+ compensation temperature and the second threshold is 1°c+ compensation temperature.
In other cases, the first and second thresholds may be determined based on the type of caravan.
Under refrigeration or heating mode, because the temperature field in the car distributes unevenly, upper portion temperature is higher, and lower part temperature is lower, and temperature sensor receives the influence of in-car evaporator in the car simultaneously, leads to in-car temperature acquisition can not accurately reflect actual in-car temperature, influences the accurate control of air conditioner temperature to influence the travelling comfort. To improve the above problem, the temperature in the vehicle is usually compensated, and the operation process of the air conditioner is controlled by using the compensated ambient temperature value. The temperature compensation value is solidified in the memory in advance, and different users in different areas or the same area can feel different to the temperature, and the value can be changed according to the requirement.
According to one embodiment of the present invention, the step of adjusting the operation mode of the air conditioner according to the environmental state specifically includes:
s1110, determining that the environment state is a high temperature difference state, and operating the air conditioner in a strong mode;
s1120, determining that the environment state is a medium temperature difference state, and operating a powerful mode when the air conditioner is started and gradually reducing the frequency to a preset mode;
s1130, determining that the environment state is a low temperature difference state, and operating the air conditioner in a preset mode.
It can be understood that when the environment state is in a high temperature difference state, the heat transfer rate inside and outside the vehicle body is higher, and the air conditioner operates in a powerful mode, the compressor of the air conditioner operates in a high frequency mode, the indoor fan operates in a powerful mode, the temperature in the vehicle can be improved rapidly, and meanwhile, the influence caused by the temperature difference between the inside and the outside of the vehicle can be counteracted.
When the environment state is a medium temperature difference state, the heat transfer rate inside and outside the vehicle body is relatively high, and the air conditioner runs in a powerful mode when being started and then gradually reduces to a preset mode, so that the temperature in the vehicle can be quickly improved, and the influence caused by the temperature difference between the inside and the outside of the vehicle can be properly counteracted.
When the environment state is in a low temperature difference state, the heat transfer rate inside and outside the car body is low, the air conditioner does not need to operate in a strong mode, the accurate control of the temperature in the motor home can be realized according to the preset mode, the air conditioner operates according to the preset mode, the energy consumption of the air conditioner is low, the energy saving of the motor home is facilitated, and the cruising ability is improved.
According to the control method of the motor home air conditioner provided by the embodiment of the invention, the air conditioner at least comprises a first energy saving mode, a second energy saving mode and a strong mode; in a first energy saving mode, the frequency of the compressor is a first frequency, the wind speed of the indoor unit is a first wind speed, and the working current is a first current; in a second energy-saving mode, the frequency of the compressor is a second frequency, the wind speed of the indoor unit is a second wind speed, and the working current is a second current; in the strong mode, the frequency of the compressor is the third frequency, the wind speed of the indoor unit is the third wind speed, and the working current is the third current; the second frequency, the first frequency, and the third frequency are sequentially increased, the second current, the first current, and the third current are sequentially increased, and the second wind speed, the first wind speed, and the third wind speed are sequentially increased.
In some embodiments, the first current is 75% of the third current and the second current is 50% of the third current.
Of course, the air conditioner may further include other various modes, and may operate the power mode, the first energy saving mode, the second energy saving mode, the preset mode, or the like after receiving a user's instruction.
According to one embodiment of the present invention, the step of determining that the environmental state is a high temperature difference state and the air conditioner operates in a power mode further includes:
s1111, continuously obtaining the temperature in the vehicle;
and S1112, when the absolute value of the temperature difference between the temperature in the vehicle and the set temperature is smaller than a third threshold value, the air conditioner operates in a first energy saving mode.
It can be understood that when the environment state is in a high temperature difference state, the heat transfer rate inside and outside the vehicle body is higher, and the air conditioner operates in a powerful mode, the compressor of the air conditioner operates in a high frequency mode, the indoor fan operates in a powerful mode, the temperature in the vehicle can be improved rapidly, and meanwhile, the influence caused by the temperature difference between the inside and the outside of the vehicle can be counteracted. With the operation of the powerful mode, the temperature in the vehicle is changed and gradually approaches to the set temperature, so that the operation power of the air conditioner can be properly reduced, and the energy consumption is saved.
When the air conditioner operates, the temperature in the vehicle is reduced, and when the absolute value of the difference value (comprising two conditions of heating and cooling) between the temperature in the vehicle and the set temperature is smaller than a third threshold value, the operating power of the air conditioner can be properly reduced, and the air conditioner operates in a first energy saving mode at the moment, so that the power of a compressor, the working current and the wind speed of an indoor unit of the air conditioner are reduced, the energy consumption of a motor home is saved, and the cruising ability is improved.
According to one embodiment of the present invention, after the step of operating the first energy saving mode, the air conditioner further includes:
s1113, if the duration of the air conditioner in the first energy saving mode is longer than the first preset duration, the air conditioner in the second energy saving mode is operated.
It can be appreciated that in the second energy-saving mode, the compressor power, the working current and the air speed of the indoor unit of the air conditioner are further reduced, which is beneficial to saving the energy consumption of the caravan.
According to one embodiment of the present invention, the step of determining that the duration of the air conditioner operating the first energy saving mode is greater than the first preset duration, and then operating the air conditioner in the second energy saving mode further includes:
and 1114, determining that the absolute value of the temperature difference between the temperature in the vehicle and the set temperature is greater than a third threshold value, and that the duration of the air conditioner in the second energy saving mode is less than the second preset duration, and then operating the air conditioner in the first energy saving mode.
It will be appreciated that after the air conditioner is operated in the power mode, the temperature in the caravan is rapidly reduced. The refrigerating/heating power of the air conditioner in the strong mode is greater than the heat transfer rate inside and outside the car, so that the air conditioner can be switched to the first energy saving mode.
In order to further reduce the energy consumption of the motor home, the air conditioner can be further switched to a second energy-saving mode after the first energy-saving mode is operated, and the like, so that a proper energy-saving mode can be found, and in the energy-saving mode, the refrigerating/heating power of the air conditioner and the heat transfer rate inside and outside the motor home are kept balanced, and at the moment, the temperature in the motor home can be kept, and the air conditioner can be in an optimal energy-saving state.
When the air conditioner is switched to the second energy-saving mode, the heating/cooling power of the air conditioner may be smaller than the heat transfer rate inside and outside the caravan, and when the air conditioner operates in the second energy-saving mode, the temperature in the car is gradually far away from the set temperature, for example, is greater than a third threshold value, and at this time, the air conditioner needs to be switched to the first energy-saving mode to maintain the temperature in the caravan stable.
In some embodiments, the third threshold is 1deg.C+ compensation temperature, the second preset duration is 15 minutes, i.e. after 15 minutes of switching to the second energy saving mode, a temperature change occurs rapidly in the car, and the second energy saving mode does not meet the cooling/heating requirements in the car.
According to one embodiment of the present invention, the step of determining that the duration of the air conditioner operating the first energy saving mode is greater than the first preset duration, and then operating the air conditioner in the second energy saving mode further includes:
s1115, determining that the absolute value of the temperature difference between the temperature in the vehicle and the set temperature is larger than a third threshold value, and the duration of the air conditioner in the second energy-saving mode is longer than a third preset duration, and switching to the second energy-saving mode after the air conditioner in the first energy-saving mode is in the fourth preset duration.
It can be understood that after the air conditioner is switched to the second energy-saving mode and the time period of operation in the second mode exceeds the third preset time period, the heating/cooling power of the air conditioner in the second energy-saving mode is close to the heat transfer rate inside and outside the caravan, and the temperature in the caravan changes in a longer time. When the absolute value of the temperature difference between the temperature in the vehicle and the set temperature is larger than a third threshold value, the air conditioner is switched to a first energy saving mode to timely adjust the temperature in the vehicle. After the air conditioner runs for a fourth preset time period in the first energy saving mode, the air conditioner is switched to the second energy saving mode again, so that the energy consumption of the motor home is saved as much as possible, and the temperature in the motor home does not change greatly in the second energy saving mode.
In some embodiments, the third preset duration is 1 hour and the fourth preset duration is 1 hour.
Referring to fig. 2, a control device for a motor home air conditioner according to an embodiment of the second aspect of the present invention includes:
an acquisition module 200 for acquiring an in-vehicle temperature and an out-of-vehicle temperature;
the control module 201 is configured to determine an environmental state in the caravan according to the temperature in the caravan and the temperature outside the caravan, and adjust an operation mode of the air conditioner according to the environmental state.
According to the control device for the air conditioner of the motor home, provided by the embodiment of the invention, when the operation mode of the air conditioner is adjusted, the influence of the temperature in the motor home is considered, the influence of the temperature difference between the temperature in the motor home and the temperature outside the motor home on the heat transfer rate is considered, the environmental state in the motor home is determined according to the temperature in the motor home and the temperature outside the motor home, and then the operation mode of the air conditioner is determined according to the environmental state.
When the air conditioner operates, the operation mode of the air conditioner of the motor home is adjusted according to the environment state, so that the temperature in the motor home can be quickly adjusted, the comfort level of a user is improved, and the energy consumption of the air conditioner is saved.
