In a traditional fuel vehicle, when there is a heating demand in an occupant compartment, the waste heat generated by the engine and the waste heat in the gas after combustion may heat the air through heat transfer. The heat transfer process is realized by heated cooling liquid. After gaining heat from the waste heat, the liquid coolant may flow through a heater core in a heating ventilation and air conditioning (HVAC) system, thus transferring heat to the air. The heated air will reach the occupant compartment through an air outlet to meet the heating demand for the occupant compartment. Because there are always enough waste heat sources in traditional fuel vehicles, the temperature of the air passing through the heater core is usually high enough. There is a need for a vehicle-mounted terminal to dispose a temperature sensor behind the heater core, so as to acquire a temperature of the heated air from the heater core. Thereafter, the vehicle-mounted terminal may mix unheated air into the heated air by controlling the opening value of the air mixing damper, so that the air may reach the target temperature when it is blown out from the air outlet.
In electric vehicles, the waste heat generated by the vehicles is far less than that by fuel vehicles. With the development of electric vehicle industry in recent years, more and more heat pump systems have been applied to the vehicles. When there is a heating demand in an occupant compartment, a vehicle may effectuate heating of the intake air to a heating temperature through a heat pump or a heater, for example, a positive temperature coefficient (PTC). Then, the vehicle-mounted terminal controls the air mixing damper in such a manner that the outlet air temperature at the air outlet reaches the target temperature. A calculation method of the heating temperature of the heater core for air conditioning lies in that: assuming that the opening of the air mixing damper is at a 100% full warm position, the heating temperature is equal to a sum of the target temperature and a temperature compensation.
The temperature compensation is determined by ambient temperature, air volume and other factors. Under different ambient temperatures and air volumes, the heat loss from the heater core to the air outlet varies. Therefore, the temperature compensation calculated based on this heat loss also varies. In general, in order to ensure that the temperature at the air outlet may meet the heating demand, the vehicle-mounted terminal will consciously increase the temperature compensation to meet the heating demand of the occupant compartment.
In order to save the cost, the present application puts forward a feasible solution to cancel the temperature sensor behind the heater core. And, because the air mixing damper is disposed behind the heater core, if a temperature sensor is disposed on a surface of the heater core, the disposition of the temperature sensor may inevitably affect the operation of the air mixing damper, thus bringing about potential safety hazards. At the same time, in order to respond to the high demand of electric vehicles for power consumption, strategies for more precise control of the heating demand are needed for the vehicles.
In view of the above problems, the present application proposes a control method for a heat pump system of a multi-temperature zone air conditioning box. In the present application, when the occupant compartment only has a refrigeration demand, a vehicle-mounted terminal may fix the air mixing damper at a full cool position, thus ensuring the refrigeration demand of the vehicle. In the present application, the air mixing damper may also be fixed at a full warm position when the occupant compartment has a heating demand and heating is rendered for the occupant compartment by using PTC, so as to control the outlet air temperature through PTC and make it reach a target temperature. In present application, the vehicle-mounted terminal may also make the outlet air temperature reach the target temperature by adjusting the opening value of the air mixing damper, when the occupant compartment has a heating demand and motor and/or battery waste heat heating is used. In the present application, when the occupant compartment has a heating demand and a compressor is used to heat the occupant compartment, the vehicle-mounted terminal may also control the air mixing damper according to a rotation speed of the compressor. When the rotation speed of the compressor is a non-minimum rotation speed at which the compressor is operable, for example, higher than 850 rpm, the vehicle-mounted terminal may fix the air mixing damper at the full warm position. Further, the vehicle-mounted terminal may make the outlet air temperature reach the target one by controlling the rotation speed of the compressor. When the rotation speed of the compressor is kept for more than T seconds at the minimum rotation speed at which the compressor is operable, and the difference between the outlet air temperature and the target temperature is greater than a first threshold, the vehicle-mounted terminal may fix the rotation speed of the compressor at the minimum rotation speed at which the compressor is operable. T is an empirical value, and the minimum rotation speed at which the compressor is operable may be 850 rpm. At the same time, the vehicle-mounted terminal may also adjust the opening of air mixing damper in such a manner that the outlet air temperature reaches the target one. The present application not only cancels the temperature sensor behind the heater core, but also reduces the cost. Moreover, the present application also realizes the precise control of the heating demand of occupant compartment through the vehicle-mounted terminal, thus achieving the purpose of energy conservation.
Technical solutions of the present application will be described in detail with specific embodiments. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.
In the present application, the vehicle-mounted terminal is taken as an execution subject to execute a control method for a heat pump system of a multi-temperature zone air conditioning box in the following embodiments. Specifically, the execution subject may be a hardware device of the vehicle-mounted terminal, or a software application in the vehicle-mounted terminal that implements the following embodiments, or a non-transitory computer-readable storage medium installed with the software application that implements the following embodiments, or codes of the software application that implements the following embodiments.
S101, acquiring a temperature regulation mode and a target temperature for a vehicle, and a temperature adjustment demand and an outlet air temperature of each temperature zone of the vehicle, where the outlet air temperature is measured by a temperature sensor at an air outlet corresponding to the temperature zone.
In this embodiment, the vehicle-mounted terminal may acquire the temperature regulation mode of the vehicle. The temperature regulation mode may include one or more of compressor refrigeration, heater heating, motor and/or battery waste heat heating and compressor heating. When the temperature regulation mode is compressor heating, the following cases may correspond to different calculation methods of the opening value of the air mixing damper, i.e., the case that the rotation speed of the compressor is greater than the minimum rotation speed at which the compressor is operable and the case that the rotation speed of the compressor is less than or equal to the minimum rotation speed at which the compressor is operable.
The vehicle-mounted terminal may also acquire the target temperature. The target temperature is an air conditioning temperature set by the user through the vehicle-mounted terminal. The temperature adjustment in this embodiment is configured to adjust the outlet air temperature at the air outlet, so that the outlet air temperature at each air outlet reaches the target temperature, and then the temperature of the occupant compartment reaches the target temperature.
The vehicle-mounted terminal may also acquire the temperature adjustment demand of each temperature zone. Each temperature zone includes at least one air outlet. For example, a driver's seat of the occupant compartment may be a temperature zone, and this temperature zone may include two air outlets on left and right sides of the steering wheel. For another example, a rear seat of the occupant compartment may be a temperature zone, and this temperature zone may include an air outlet. Temperature adjustment demands of different temperature zones may be determined according to air output at air outlets in different temperature zones. For example, when the two air outlets in the temperature zone corresponding to the driver's seat are all open, the corresponding temperature adjustment demand thereof may be 2. When only one of the two air outlets in the temperature zone corresponding to the driver's seat is opened, the corresponding temperature adjustment demand thereof may be 1. When one of the two air outlets in the temperature zone corresponding to the driver's seat is closed, and the other is half-opened, the temperature adjustment demand thereof may be 0.5. For another example, when a size of the air outlet for the rear seat is 1.5 times that of the air outlet for the driver's seat and when the air outlet of the rear seat is opened, the temperature adjustment demand of the temperature zone is 1.5.
The vehicle-mounted terminal may also acquire the outlet air temperature of each air outlet through the temperature sensor disposed at each air outlet.
S102, adjusting an opening value of an air mixing damper in each temperature zone according to the temperature regulation mode, the target temperature, and the temperature adjustment demand and the outlet air temperature of each temperature zone, so that the outlet air temperature of each temperature zone reaches the target temperature.
In this embodiment, the vehicle-mounted terminal may calculate the opening value of the air mixing damper according to the temperature regulation mode, the target temperature, and the temperature adjustment demand and the outlet air temperature of each temperature zone acquired in S101. The vehicle-mounted terminal may adjust the amount of untreated air that may be mixed in each air mixing damper by controlling the opening of the air mixing damper. The vehicle-mounted terminal may realize the adjustment of the temperature of the air blown out from the air outlet by adding different amounts of untreated air to cold air/hot air.
In an example, when an air mixing damper in the vehicle corresponds to multiple air outlets, the amount of untreated air entering from the air mixing damper will determine the outlet air temperatures at the multiple air outlets corresponding to the air mixing damper. In this case, after acquiring the temperatures at the multiple air outlets corresponding to the air mixing damper, the vehicle-mounted terminal may calculate the temperature difference of the multiple air outlets as a whole to acquire the opening of the air mixing damper. The specific steps may include:
In another example, each air outlet in each temperature zone of the vehicle may correspond to an air mixing damper. The air mixing damper may mix the untreated air with the air to be blown out from the air outlet, so that the outlet air temperature at the air outlet reaches the target temperature. In this case, the vehicle-mounted terminal may calculate the opening value of the air mixing damper at each air outlet according to the outlet air temperature of the air outlet. The specific steps thereof may include:
In this embodiment, besides directly calculating the opening value of the air mixing damper, it is also necessary to adjust the opening value of the air mixing damper according to the temperature regulation mode. Under different temperature regulation modes, different configurations of opening values may be shown in the following examples.
In an example, when the temperature regulation mode is any one of compressor refrigeration, heater heating and compressor heating in which the rotation speed of the compressor is greater than the minimum rotation speed at which the compressor is operable, the specific calculation method of the opening value includes the following steps.
Step 1, determining a first temperature zone with a maximum temperature adjustment demand according to the temperature adjustment demand of each temperature zone.
In this step, the vehicle-mounted terminal may acquire the air output of each temperature zone. The vehicle-mounted terminal may determine the temperature adjustment demand of each temperature zone according to the air output. The vehicle-mounted terminal may compare temperature adjustment demands of individual temperature zones, thus determining a temperature zone with a maximum temperature adjustment demand. The vehicle-mounted terminal may determine the temperature zone with the maximum temperature adjustment demand to be the first temperature zone, and determine temperature zones except for the first temperature zone to be other temperature zones.
Step 2, setting an opening value of an air mixing damper in the first temperature zone as a fixed value.
In this step, the fixed value includes 0% and 100%. When the temperature regulation mode is heating, the fixed value may be set to 100%, that is, full warm. When the temperature regulation mode is refrigeration, the fixed value may be set to 0, that is, full cool.
Step 3, adjusting opening values of air mixing dampers in other temperature zones except for the first temperature zone according to the target temperature and outlet air temperatures of the other temperature zones.
In this step, the vehicle-mounted terminal may calculate the opening value of the air mixing damper in each temperature zone by the method calculating the opening value of the air mixing damper according to the outlet air temperature and the target temperature in the previous example.
For example, when the occupant compartment only has a refrigeration demand, the temperature regulation mode is compressor refrigeration. The vehicle-mounted terminal may determine, from multiple temperature zones, the temperature zone with a maximum refrigeration demand in the air conditioning box as the first temperature zone. The vehicle-mounted terminal may fix the air mixing damper corresponding to the first temperature zone at a full cool position. At the same time, the vehicle-mounted terminal regulates the opening values of the air mixing dampers in other temperature zones according to the outlet air temperatures at the air outlets in the other temperature zones and the target temperature.
For another example, when the occupant compartment has a heating demand and only PTC is used to heat the occupant compartment, the vehicle-mounted terminal may determine, from multiple temperature zones, the temperature zone with a maximum heating demand in the air conditioning box as the first temperature zone. The vehicle-mounted terminal may fix the air mixing damper corresponding to the first temperature zone at a full warm position. At the same time, the vehicle-mounted terminal make the outlet air temperature corresponding to the first temperature zone reach the target one by controlling an output power of the PTC in the first temperature zone. The vehicle-mounted terminal regulates the opening values of the air mixing dampers in other temperature zones according to the outlet air temperatures at the air outlets in the other temperature zones and the target temperature.
For another example, when the occupant compartment has a heating demand and both the PTC and the compressor are used to heat the occupant compartment, the vehicle-mounted terminal may determine, from multiple temperature zones, the temperature zone with the maximum heating demand in the air conditioning box as the first temperature zone. The vehicle-mounted terminal may fix the air mixing damper corresponding to the first temperature zone at the full warm position. At the same time, the compressor runs at an upper speed limit set in this working condition, and the vehicle-mounted terminal may control the output power of the PTC to make the outlet air temperature corresponding to the first temperature zone reach the target one. The vehicle-mounted terminal regulates the opening values of the air mixing dampers in other temperature zones according to the outlet air temperatures at the air outlets in the other temperature zones and the target temperature.
For another example, when the occupant compartment has a heating demand, and only the compressor is used to heat the occupant compartment, if the rotation speed of the compressor is a non-minimum rotation speed at which it is operable, for example, the rotation speed of the compressor is higher than 850 rpm, the vehicle-mounted terminal may determine, from multiple temperature zones, the temperature zone with the maximum heating demand in the air conditioning box as the first temperature zone. The vehicle-mounted terminal may fix the air mixing damper corresponding to the first temperature zone at the full warm position. The vehicle-mounted terminal may make the outlet air temperature corresponding to the first temperature zone reach the target one by controlling the rotation speed of the compressor. At the same time, the vehicle-mounted terminal regulates the opening values of the air mixing dampers in other temperature zones according to the outlet air temperatures at the air outlets in the other temperature zones and the target temperature.
In another example, when the temperature regulation mode is motor and/or battery waste heat heating or compressor heating in which the rotation speed of the compressor is less than or equal to the minimum rotation speed at which the compressor is operable, the opening value of the air mixing damper may be determined according to the target temperature and the outlet air temperature of each temperature zone, thus completing the adjustment of the air mixing damper in each temperature zone. The rotation speed of the compressor is less than or equal to the minimum rotation speed at which the compressor is operable, then the rotation speed of the compressor may be 850 rpm.
For example, when the occupant compartment has a heating demand, and the motor and/or battery waste heat heating is used to heat the occupant compartment, the vehicle-mounted terminal may not directly limit the opening of any air mixing damper. The opening value of each air mixing damper in the vehicle may be calculated by the outlet air temperature and the target temperature, so as to realize the regulation of the opening of each air mixing damper and make the outlet air temperature at each air outlet reach the target temperature.
For another example, when the occupant compartment has a heating demand and only the compressor is used to heat the occupant compartment, if preset conditions are met, the rotation speed of the compressor is fixed at the minimum rotation speed at which it is operable, and the opening of any air mixing damper is not directly limited. The opening value of each air mixing damper in the vehicle may be calculated by the outlet air temperature and the target temperature, so as to achieve regulation of the opening of each air mixing damper and make the outlet air temperature at each air outlet reach the target temperature. The preset conditions may include that the duration of the rotation speed of the compressor exceeds a first threshold, and that the difference between the outlet air temperature and the target temperature is greater than a second threshold.
In the control method for the heat pump system of the multi-temperature zone air conditioning box provided in the present application, the vehicle-mounted terminal may acquire the temperature regulation mode and the target temperature for the vehicle, the temperature adjustment demand and the outlet air temperature of each temperature zone of the vehicle. The vehicle-mounted terminal may adjust opening value of the air mixing damper in each temperature zone according the temperature regulation mode, the target temperature and the temperature adjustment demand and the outlet air temperature of each temperature zone, so that the outlet air temperature of each temperature zone reaches the target temperature. In the present application, precise control of the heating/refrigeration demand of the occupant compartment is realized by combining the following two ways: directly limiting the opening value of the air mixing damper according to the temperature regulation mode and calculating the opening value of the air mixing damper according to the difference between the outlet air temperature and the target temperature. At the same time, the temperature sensor disposed at the air outlet is used in the present application instead of the temperature sensor disposed behind the heater core in the prior art, so that the cost is reduced and the purpose of energy saving is achieved.
In an example, the temperature regulation mode includes one or more of compressor refrigeration, heater heating, motor and/or battery waste heat heating and compressor heating.
