Since control panel can carry out actual design, and not key protection point of the invention according to actual needs, on
It states and is just simply illustrated, moreover, the present invention is also not limited to above-mentioned control panel.Control model is carried out below specific
Illustrate, i.e., compartment temperature control method provided by the invention is specifically described.
As shown in figure 5, the first step is operating mode selection after control device is opened, control panel mode selecting operation is control
The input of system answers control model according to the logic diagram output phase.
As shown in fig. 6, the logic diagram is shown in the input and output under " automatic control " mode.Control logic illustrates such as
Under:
Two temperature thresholds are set, one is heating temperature threshold value, the other is cryogenic temperature threshold value, when temperature in compartment
When less than or equal to the heating temperature threshold value, indicate that temperature is lower in compartment, heats；When temperature is greater than in compartment
Or when being equal to the cryogenic temperature threshold value, indicate that temperature is higher in compartment, freezes.
In the present embodiment, heating temperature threshold value is set as 10 DEG C, and cryogenic temperature threshold value is set as 24 DEG C, this is that basis multiplies
The general changes in temperature impression of visitor is come what is be arranged, and certainly, as other embodiments, the two temperature thresholds can also be according to practical feelings
Condition is arranged to other temperature values.
Enter prepared heating state when temperature≤10 DEG C in compartment, first determine whether the intention of driver, specifically: if at this time
Radiator fan is closed, and indicates that driver without heating wish, then enters standby mode；If radiator fan is opened, indicate that driver has heating
Wish then enters heating control state.Certainly, judge that the intention of driver belongs to the embodiment of optimization, implement as others
Mode can not have to the intention for judging driver, be directly entered heating control.
The heating control method is the temperature of foundation engine cooling water to be controlled, so, in heating, first
The temperature of engine cooling water is detected, then the different range according to locating for the temperature of cooling water there are several different heating moulds
Formula.In control, four temperature ranges, corresponding three set temperature values, respectively the first set temperature need to set are set
Value, the second set temperature value and third set temperature value, the first set temperature value are set less than the second set temperature value, described second
Temperature value is determined less than third set temperature value, and in the present embodiment, these three set temperature values are respectively set to 60 DEG C, 70 DEG C and 85
DEG C, similarly, these three set temperature values are also not limited to above three actual temp value, but can be according to actual needs
Carry out actual set.
Heating mode difference is as follows:
When temperature≤60 DEG C of engine cooling water, cooling water is heated in auxiliary heater unlatching, radiator fan
Temporary close, and prompt: water temperature is relatively low, temporary close radiator fan.The temperature of engine cooling water is relatively low at this time, to guarantee
Engine behavior is good, currently should quickly improve the temperature of engine cooling water, reduces heat and distributes.
When 70 DEG C of temperature < of 60 DEG C of < engine cooling waters, cooling water is heated in auxiliary heater unlatching, dissipates
The low velocity threshold (the present embodiment is by taking 1000rpm as an example) that Hot-air fan is set by one carries out low-speed running, provides certain heating,
It is currently to maintain based on engine cooling water temperature, supplemented by heat dissipation.
When 85 DEG C of temperature < of 70 DEG C≤engine cooling water, the temperature drift of engine cooling water at this time, engine
Cooling water can normally heat, then radiator fan with rated speed operating (rated speed can be manually set, such as
3000rpm is also possible to running speed of the radiator fan under declared working condition, such as rated power, moreover, low velocity threshold is less than
Rated speed), but the temperature of engine cooling water is not up to engine optimum working temperature (85 DEG C), then and auxiliary heater continues
Auxiliary heating is carried out to cooling water, improves engine cooling water temperature.
When temperature >=85 DEG C of engine cooling water, i.e. engine reaches optimum working temperature, and engine, which normally heats, to be dissipated
Heat, the operating of radiator fan rated speed, the temperature of engine cooling water can lean on engine itself operating to maintain, then assist heating
Device is closed.
As shown in fig. 7, providing a kind of system that cooling water heats, wherein 1 is engine, and 2 be electric water pump, and 3 are
Heater, 4 be compartment inner radiator.Since the system belongs to existing system, no longer it is described in detail here.
Enter refrigeration control state when temperature >=24 DEG C in compartment.Refrigeration control method is according to temperature and vehicle outside compartment
Temperature is controlled in compartment, specific as follows:
Temperature in temperature and compartment is detected outside compartment first.
Then, when temperature in the compartment temperature > outside compartment, the setting target temperature value an of comparison, this implementation are set
In example, target temperature value is set for 26 DEG C.Temperature is compared with setting target temperature value in compartment, if temperature in compartment
> sets target temperature value, and into refrigeration mode, i.e. compressor of air conditioner opens refrigeration, air-conditioning draught fan full-speed operation；If in compartment
Temperature≤setting target temperature value, into ventilation mode, i.e. compressor of air conditioner does not work, circulating ventilation in air-conditioning；
When temperature in temperature≤compartment outside compartment, enter external ventilation mode at this time, i.e. compressor of air conditioner does not work, empty
Outer circulation ventilation is adjusted, temperature in compartment is reduced with cooler air outside compartment.
In addition, the system of can control is in standby if 10 DEG C of < are 24 DEG C of temperature < in compartment, neither freeze,
Also it does not heat.
Above-mentioned heating control and refrigeration control is automatic mode, certainly, heating control method and refrigeration control method
It can also be manual mode, specific as follows:
As shown in figure 8, the logic diagram is shown in the input and output under " heating manually " mode.Control logic is as follows: when
When temperature≤60 DEG C of engine cooling water, cooling water is heated in auxiliary heater unlatching, radiator fan temporary close, and
Prompt: water temperature is relatively low, temporary close radiator fan.The temperature of engine cooling water is relatively low at this time, to guarantee engine operation
It is in good condition, the temperature of engine cooling water currently should be quickly improved, heat is reduced and distributes.
When 70 DEG C of temperature < of 60 DEG C of < engine cooling waters, cooling water is heated in auxiliary heater unlatching, dissipates
The low velocity threshold that Hot-air fan is set with one carries out low-speed running, provides certain heating, is currently to maintain engine cooling water
Based on temperature, supplemented by heat dissipation.
When 85 DEG C of temperature < of 70 DEG C≤engine cooling water, the temperature drift of engine cooling water at this time, engine
Cooling water can normally heat, then radiator fan is operated with rated speed, but the temperature of engine cooling water is not up to engine
Optimum working temperature (85 DEG C), then auxiliary heater continues to carry out cooling water auxiliary heating, improves engine cooling water temperature.
When temperature >=85 DEG C of engine cooling water, i.e. engine reaches optimum working temperature, and engine, which normally heats, to be dissipated
Heat, the operating of radiator fan rated speed, the temperature of engine cooling water can lean on engine itself operating to maintain, then assist heating
Device is closed.
So either manual mode or automatic mode, heating control strategy do not change.
Either manual mode or automatic mode are independent between several heating modes, are according to coolant water temperature
The section that degree meets accordingly controls heating, and certainly, there is also certain connection between these types of heating mode, engine is cold
But which section coolant-temperature gage reaches in, is just controlled in a manner of the corresponding heating control in the section.For example, when engine is cold
But when temperature≤60 DEG C of water, cooling water is heated in control heater unlatching, and cooling water temperature is gradually increasing, and works as cooling water
When temperature meets 70 DEG C of temperature < of 60 DEG C of < engine cooling waters, heating control is just carried out with control mode under this condition at this time
System, heater is to open under this condition, then cooling water temperature is gradually increasing, as the temperature < of 70 DEG C≤engine cooling water
At 85 DEG C, heating control mode just changes into heating control mode under this condition, and heater continues to carry out cooling water
Heating, engine cooling water temperature is further up, when the temperature of engine cooling water rises above or is equal to 85 DEG C,
Heating control mode just changes into heating control mode under this condition.
As shown in figure 9, the logic diagram is shown in the input and output under " refrigeration manually " mode.Control logic illustrates such as
Under: when temperature in the compartment temperature > outside compartment, the target temperature value of a comparison is set, the mesh of temperature and setting in compartment
Mark temperature value is compared, if temperature > sets target temperature value in compartment, into refrigeration mode, i.e. compressor of air conditioner opens system
It is cold, air-conditioning draught fan full-speed operation；If temperature≤setting target temperature value in compartment, not into ventilation mode, i.e. compressor of air conditioner
It works, circulating ventilation in air-conditioning；
When temperature in temperature≤compartment outside compartment, enter external ventilation mode at this time, i.e. compressor of air conditioner does not work, empty
Outer circulation ventilation is adjusted, temperature in compartment is reduced with cooler air outside compartment.
So either manual mode or automatic mode, also there is no variations for refrigeration control strategy.
In addition, vehicle can be aerated when without heating also without refrigeration, and as shown in Figure 10, the logical box
Figure is shown in the input and output under " ventilation " mode.Control logic is described as follows:
When temperature≤15 DEG C in compartment, ventilation mode is inner ventilation；
When 15 DEG C of temperature > in compartment, and in compartment outside the compartment temperature > when temperature, then enter inner-outer circulation ventilation mode
(carrying out within first outer circulation 10 minutes interior circulation again 30 minutes, then continue to outer circulation 10 minutes, so recycle) is until in compartment
Outer temperature is identical；When 15 DEG C of temperature > in compartment, and in compartment outside temperature≤compartment when temperature, ventilation mode is inner ventilation.
It should be noted that the ventilation mode is an independent control model, with above-mentioned heating control and refrigeration control
Independently of each other.
In above-described embodiment, two temperature thresholds are set, one is heating temperature threshold value, the other is cryogenic temperature threshold
Value carries out heating control when temperature is less than or equal to the heating temperature threshold value in compartment；When in compartment temperature be greater than or
When equal to the cryogenic temperature threshold value, refrigeration control is carried out, and give a kind of specific refrigeration control strategy.But this hair
It is bright to be not limited to the refrigeration control strategy, as other embodiments, other existing refrigeration in existing can also be used
Control strategy or the present invention only carry out heating control, without refrigeration control.
In above-described embodiment, temprature control method is illustrated on the basis of control panel, but due to control
Panel is not emphasis of the invention, and of the invention focuses on temprature control method, so, temperature controlling party provided by the invention
Method is not limited to above-mentioned control panel, and regardless of the temprature control method is to implement in what manner, as long as implementing to fall
Within protection scope of the present invention.
