Description

Technical Field

[0001] The present application relates to the technical field of air-conditioning systems, and in particular to an automobile air-conditioning control method, system, intelligent terminal, and readable storage medium. Background Art

[0002] Based on the thermal balance of current automotive engines, the power used for power output generally accounts for only 30%-45% (diesel engines) and 20%-30% (gasoline engines) of the total heat generated by fuel combustion. The energy discharged from the vehicle as waste heat accounts for 55%-70% (diesel engines) and 80%-70% (gasoline engines) of the total combustion energy, primarily consisting of heat removed by circulating cooling water and exhaust gases.

[0003] In heavy trucks and heavy machinery, the use of engine exhaust waste heat for adsorption refrigeration can meet the indoor air conditioning load. This is because the cabs of heavy trucks and heavy machinery are small and the engine exhaust emissions are large. The cooling capacity of the adsorption refrigeration equipment that recovers waste heat alone can meet the indoor cooling load demand.

[0004] Since light and medium-sized buses have a large number of passengers and a large volume, the cooling load of the vehicles is relatively large. In order to meet the indoor load in light and medium-sized buses, the exhaust temperature drop required is large. However, such a large temperature drop cannot be achieved in actual buses. Therefore, simply using the waste heat from the engine exhaust for adsorption cooling cannot meet the indoor load and auxiliary equipment must be added.

[0005] For light and medium-sized buses, exhaust waste heat recovery cannot meet the actual cooling needs. Reducing vehicle energy consumption while meeting the vehicle's cooling needs and user comfort is a problem that needs to be overcome in the current control methods of automotive air-conditioning equipment. Summary of the Invention

According to the unit temperature power consumption set, the unit temperature comfort set and the cost-effectiveness determination rule, the comfort cost-effectiveness data can be calculated, and the car air conditioner is controlled to control the temperature at the optimal theoretical temperature corresponding to the comfort cost-effectiveness data.

DETAILED DESCRIPTION

[0052] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0053] In this document, the term "and / or" simply describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document, unless otherwise specified, generally indicates an "or" relationship between the related objects.

[0054] The embodiments of the present application are described in further detail below with reference to the accompanying drawings.

[0055] An embodiment of the present application provides a method for controlling an automobile air conditioner, and the main process of the method is described as follows.

[0056] like Figure 1 As shown:

[0057] S101: Obtain vehicle data and vehicle interior temperature.

[0058] Specifically, the engine model, exhaust volume, exhaust temperature, and vehicle speed are acquired through human input or an onboard data collector. The interior temperature can be acquired through a temperature sensor. For example, for an Nj4105QZL engine, the exhaust temperature is 500°C, the exhaust volume is 0.12 m³ / s, the vehicle speed is 10 km / h, and the interior temperature is 32°C. This acquired vehicle data provides the foundation for subsequent calculations.

[0059] S102: Determine the waste heat temperature according to the waste heat energy consumption rule, vehicle data, and the temperature inside the vehicle.

[0060] Specifically, the waste heat energy consumption table includes vehicle data, theoretical drop temperature, and the correspondence between the vehicle data and the theoretical drop temperature. By obtaining the vehicle data, the theoretical drop temperature can be obtained through the correspondence between the vehicle data and the theoretical drop temperature. The waste heat temperature can be calculated through the theoretical drop temperature. In this embodiment, the temperature that can be reduced obtained from the vehicle data and the waste heat energy consumption table, that is, the theoretical drop temperature is 2°C, then the waste heat temperature represents the temperature inside the vehicle that can be reduced by the waste heat of the exhaust gas, so the waste heat temperature is the temperature inside the vehicle - the theoretical drop temperature, that is, 32°C - 2°C = 30°C.

[0061] S103: Determine the theoretical temperature according to the comfort table.

[0062] Specifically, the comfort table includes temperature, comfort, and the correspondence between temperature and comfort. The theoretical temperature is the temperature with the highest comfort. In the comfort table of this embodiment, 100 represents the highest comfort, and the in-car temperature corresponding to the comfort level of 100 is 25°C, so the theoretical temperature is 25°C.

[0063] S104: Determine a unit temperature comfort level set according to the comfort level table, the residual heat temperature, and the theoretical temperature.

[0064] Specifically, the unit temperature comfort level set includes all temperatures between the theoretical temperature and the waste heat temperature and the comfort levels corresponding to the temperatures. In this embodiment, the theoretical temperature is 25°C, the waste heat temperature is 30°C, and the unit temperature comfort level set includes a comfort level of 100 corresponding to 25°C, a comfort level of 95 corresponding to 26°C, a comfort level of 85 corresponding to 27°C, a comfort level of 70 corresponding to 28°C, a comfort level of 50 corresponding to 29°C, and a comfort level of 25 corresponding to 30°C.

[0065] S105: Determine power consumption data and a set of power consumption per unit temperature according to the waste heat temperature, the theoretical temperature, and the power consumption rule.

[0066] Specifically, the power consumption table includes a first temperature, a second temperature, and the amount of power required to drop from the first temperature to the second temperature. The power consumption data includes the amount of power required to drop from the waste heat temperature to the theoretical temperature. The unit temperature power consumption set includes the power consumption corresponding to any adjacent temperatures between the theoretical temperature and the waste heat temperature. In this embodiment, the difference between adjacent temperatures is 1°C. In other embodiments, the difference between adjacent temperatures can be other values ​​such as 0.5°C or 1.5°C. In this embodiment, when obtaining power consumption data, the first temperature is the waste heat temperature and the second temperature is the theoretical temperature. The power consumption data can be obtained according to the power consumption table. That is, if the power corresponding to dropping from 30°C to 25°C is 5%, then the power consumption data is 5%. The unit temperature power consumption set includes adjacent temperatures between the theoretical temperature and the waste heat temperature and the power consumption data corresponding to the adjacent temperatures. In this embodiment, the unit temperature power consumption set includes power temperature difference data of 2% from 25°C to 26°C, power temperature difference data of 1.4% from 26°C to 27°C, power temperature difference data of 1% from 27°C to 28°C, power temperature difference data of 0.5% from 28°C to 29°C, and power temperature difference data of 0.1% from 29°C to 30°C.

[0067] S106: Determine the optimal theoretical temperature according to the unit temperature power consumption set, the unit temperature comfort set, and the cost-performance ratio determination rule.

[0068] Specifically, the unit comfort cost performance data of any adjacent temperature between the waste heat temperature and the theoretical temperature is calculated, and the difference between any adjacent temperatures is the adjacent preset value. In this embodiment, the adjacent preset value is 1°C. The comfort cost performance data is determined based on the unit comfort cost performance data. The comfort cost performance data is equal to the sum of the unit comfort cost performance data. It is judged whether the comfort cost performance data is lower than the comfort cost performance preset value. If so, the theoretical temperature is the optimal theoretical temperature; if not, the comfort cost performance data corresponding to the next theoretical temperature is calculated and judged, and the next theoretical temperature = theoretical temperature + adjacent preset value; the calculation method of the unit comfort cost performance data includes: the adjacent temperatures are the third temperature and the fourth temperature, and the third temperature is greater than the fourth temperature; the unit comfort cost performance data = the power consumption from the third temperature to the fourth temperature / |the comfort level corresponding to the third temperature - the comfort level corresponding to the fourth temperature|×(the power consumption from the third temperature to the fourth temperature / the power consumption data).

[0069] In this embodiment, the waste heat temperature is 30°C, the theoretical temperature is 25°C, and the resulting power consumption data is 5°C. The unit temperature power consumption set includes power temperature difference data of 2% from 25°C to 26°C, power temperature difference data of 1.4% from 26°C to 27°C, power temperature difference data of 1% from 27°C to 28°C, power temperature difference data of 0.5% from 28°C to 29°C, and power temperature difference data of 0.1% from 29°C to 30°C. The unit temperature comfort level set includes: a comfort level of 100 for 25°C, a comfort level of 95 for 26°C, a comfort level of 85 for 27°C, a comfort level of 70 for 28°C, a comfort level of 50 for 29°C, and a comfort level of 25 for 30°C. The unit comfort cost performance data include the unit comfort cost performance data of 25℃ to 26℃, the unit comfort cost performance data of 26℃ to 27℃, the unit comfort cost performance data of 27℃ to 28℃, the comfort cost performance data of 28℃ to 29℃ and the unit comfort cost performance data of 29℃ to 30℃, and the comfort cost performance of 25℃ to 26℃ is the first cost performance, the comfort cost performance of 26℃ to 27℃ is the second cost performance, the comfort cost performance of 27℃ to 28℃ is the third cost performance, the comfort cost performance of 28℃ to 29℃ is the fourth cost performance, and the comfort cost performance of 29℃ to 30℃ is the fifth cost performance. The first cost performance is 2% / 5×(2% / 5%)=0.16%, and the second cost performance is 1.4% / 1 0×(1.4% / 5%)=0.0392%, the third cost-effectiveness is 1% / 15×(1% / 5%)=0.013%, the fourth cost-effectiveness is 0.5% / 20×(0.5% / 5%)=0.0025%, and the fifth cost-effectiveness is 0.1% / 25×(0.1% / 5%)=0.00008%; the comfort cost-effectiveness data = the sum of the unit comfort cost-effectiveness data, that is, 0.16%+0.0392%+0.013%+0.0025%+0.00008%=0.21428%, then the comfort cost-effectiveness data from 25℃ to 30℃ is 0.21428%. By the same token, the comfort cost-effectiveness data from 26℃ to 30℃ is 0.09183%.

[0070] In this embodiment, according to the comfort cost performance determination rule, the unit comfort cost performance data of 25°C to 30°C is 0.21428%, and the unit comfort cost performance data of 26°C to 30°C is 0.09183%. When the comfort cost performance preset value is 1%, the comfort cost performance data of 25°C to 30°C exceeds 1%, then the comfort cost performance data corresponding to the next theoretical temperature is calculated, that is, the comfort cost performance data of 26°C to 30°C is calculated. If the comfort cost performance data of 26°C to 30°C is lower than 1%, then the theoretical temperature is 26°C, so the control signal is output to control the car air conditioner at the most appropriate temperature of 26°C. If the comfort cost performance data of 26°C to 30°C is still greater than the comfort cost performance preset value, then the next control signal is output. When the theoretical temperature is 27℃, the comfort cost performance data from 27℃ to 30℃ will continue to be calculated. If the comfort cost performance data from 27℃ to 30℃ is still higher than the comfort cost performance preset value, the comfort cost performance data from 28℃ to 30℃ will no longer be calculated, because the comfort level corresponding to 28℃ is 70. When the comfort level is lower than 80, it is considered that the comfort level is too low and it is an unsuitable air-conditioning temperature, so no calculation will be performed. If the comfort cost performance data from 27℃ to 30℃, the comfort cost performance data from 26℃ to 30℃, and the comfort cost performance data from 25℃ to 30℃ are all greater than the comfort cost performance preset value, the three will be compared and the corresponding smallest comfort cost performance data will be selected as the appropriate air-conditioning temperature, that is, the optimal theoretical temperature.
