Because control panel can carry out actual design, and not the key protection point of the present invention according to actual needs, on
State and be just simply illustrated, and, the present invention is also not limited to above-mentioned control panel.Hereinafter control model is carried out specifically
Illustrate, the compartment temperature the control method present invention being provided is specifically described.
As shown in figure 5, the first step selects for mode of operation after control device is opened, control panel mode selecting operation is control
The input of system, exports corresponding control model according to this logic diagram.
As shown in fig. 6, this logic diagram is shown in the input and output under " automatically controlling " pattern.Control logic illustrates such as
Under:
Two temperature thresholds of setting, one is heating temperature threshold value, and another is cryogenic temperature threshold value, when temperature in compartment
During less than or equal to this heating temperature threshold value, represent that in compartment, temperature is relatively low, need to be heated；When in compartment, temperature is more than
Or when being equal to this cryogenic temperature threshold value, represent that in compartment, temperature is higher, need to be freezed.
In the present embodiment, heating temperature threshold value is set to 10 DEG C, and cryogenic temperature threshold value is set to 24 DEG C, and this is that basis is taken advantage of
The general changes in temperature of visitor are experienced to arrange, and certainly, as other embodiments, this two temperature thresholds can also be according to actual feelings
Condition is arranged to other temperature values.
Enter preparation heating state when temperature≤10 DEG C in compartment, first determine whether the intention of driver, if particularly as follows: now
Radiator fan cuts out, and represents that driver no warms oneself wish, then enter holding state；If radiator fan is opened, represent that driver has heating
Wish, then enter heating control state.Certainly, judge that the intention of driver belongs to the embodiment of optimization, implement as other
Mode, can be directly entered heating control without the intention judging driver.
This heating control method is to be controlled according to the temperature of engine cooling water, so, in heating, first
Detect the temperature of engine cooling water, then the different range according to residing for the temperature of cooling water has several different heating moulds
Formula.When controlling, four temperature ranges are set, correspondence is accomplished by arranging three set temperature value, the respectively first design temperature
Value, the second set temperature value and the 3rd set temperature value, the first set temperature value sets less than the 3rd less than the second set temperature value
Constant temperature angle value, in the present embodiment, these three set temperature value are respectively set to 60 DEG C, 70 DEG C and 85 DEG C, and similarly, these three set
Constant temperature angle value is also not limited to above three actual temp value, but can carry out actual set according to actual needs.
Heating mode is as follows respectively:
When temperature≤60 DEG C of engine cooling water, auxiliary heater is opened and cooling water is heated, radiator fan
Temporary close, and point out: water temperature is low, temporary close radiator fan.Now the temperature ratio of engine cooling water is relatively low, for ensureing
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, auxiliary heater is opened and cooling water is heated, and dissipates
Hot-air fan carries out low-speed running by the low velocity threshold (the present embodiment is taking 1000rpm as a example) of a setting, provides certain heating installation,
It is currently to maintain based on engine cooling water temperature, supplemented by radiating.
When 85 DEG C of temperature ＜ of 70 DEG C≤engine cooling water, the now temperature drift of engine cooling water, electromotor
Cooling water can normally heat, then with rated speed operating, (this rated speed can be manually set radiator fan, such as
The 3000rpm or radiator fan running speed under declared working condition, such as rated power, and, low velocity threshold is less than
Rated speed), but the temperature of engine cooling water is not up to electromotor optimum working temperature (85 DEG C), then and auxiliary heater continues
Cooling water is carried out with auxiliary heating, improves engine cooling water temperature.
When temperature >=85 DEG C of engine cooling water, that is, electromotor reaches optimum working temperature, and normal heating of electromotor dissipates
Heat, radiator fan rated speed operates, and the temperature of engine cooling water can lean on electromotor itself operating to maintain, then auxiliary heating
Device cuts out.
As shown in fig. 7, providing the system that a kind of cooling water is heated, wherein, 1 is electromotor, and 2 is electric water pump, and 3 are
Heater, 4 is compartment inner radiator.Because this 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 car outside compartment
In railway carriage or compartment, temperature is controlled, specific as follows:
Temperature in temperature and compartment outside detection compartment first.
Then, when temperature in temperature ＞ compartment outside compartment, a target setting temperature value comparing, this enforcement are set
In example, target setting temperature value is taking 26 DEG C as a example.In compartment, temperature and target setting temperature value are compared, if temperature in compartment
＞ target setting temperature value, enters refrigeration mode, and that is, compressor of air conditioner opens refrigeration, air-conditioning draught fan full-speed operation；If in compartment
Temperature≤target setting temperature value, enters air vent mode, and that is, compressor of air conditioner does not work, and air-conditioning interior circulation is divulged information；
When temperature in temperature≤compartment outside compartment, now enter external ventilation pattern, that is, compressor of air conditioner does not work, empty
Adjust outer circulation ventilation, reduce temperature in compartment with cooler air outside compartment.
In addition, if 10 DEG C of ＜ work as 24 DEG C of temperature ＜ in compartment, holding state can be in control system, neither freeze,
Also do not heat.
Above-mentioned heating control and refrigeration control are all automatic modes, certainly, heating control method and refrigeration control method
Can also be manual mode, specific as follows:
As shown in figure 8, this logic diagram is shown in the input and output under " heating manually " pattern.Control logic is as follows: when
During temperature≤60 DEG C of engine cooling water, auxiliary heater is opened and cooling water is heated, radiator fan temporary close, and
Prompting: water temperature is low, temporary close radiator fan.Now the temperature ratio of engine cooling water is relatively low, for ensureing electromotor work
In good condition, currently should quickly improve the temperature of engine cooling water, reduce heat and distribute.
When 70 DEG C of temperature ＜ of 60 DEG C of ＜ engine cooling waters, auxiliary heater is opened and cooling water is heated, and dissipates
Hot-air fan carries out low-speed running with the low velocity threshold of a setting, provides certain heating installation, is currently to maintain engine cooling water
Based on temperature, supplemented by radiating.
When 85 DEG C of temperature ＜ of 70 DEG C≤engine cooling water, the now temperature drift of engine cooling water, electromotor
Cooling water can normally heat, then radiator fan is operated with rated speed, but the temperature of engine cooling water is not up to electromotor
Optimum working temperature (85 DEG C), then auxiliary heater continuation carries out auxiliary heating to cooling water, improves engine cooling water temperature.
When temperature >=85 DEG C of engine cooling water, that is, electromotor reaches optimum working temperature, and normal heating of electromotor dissipates
Heat, radiator fan rated speed operates, and the temperature of engine cooling water can lean on electromotor itself operating to maintain, then auxiliary heating
Device cuts out.
So, no matter being manual mode or automatic mode, heating control strategy does not change.
No matter being manual mode or automatic mode, being independent between several heating modes, being all according to coolant water temperature
The interval that degree meets accordingly to control heating, certainly, there is also certain contact, electromotor is cold between this several heating mode
But which interval coolant-temperature gage reaches in, is just controlled in this interval corresponding heating control mode.Such as, when electromotor is cold
But, during temperature≤60 DEG C of water, control heater to open and cooling water is heated, 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, now just heating is carried out with the control mode under the conditions of this and control
System, this condition lower heater is to open, then cooling water temperature is gradually increasing, when temperature ＜ of 70 DEG C≤engine cooling water
When 85 DEG C, heating control mode just change into this under the conditions of heating control mode, and heater continue cooling water is carried out
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 change into this under the conditions of heating control mode.
As shown in figure 9, this logic diagram is shown in the input and output under " freezing manually " pattern.Control logic illustrates such as
Under: when temperature in temperature ＞ compartment outside compartment, a target temperature value comparing is set, temperature and the mesh setting in compartment
Mark temperature value is compared, if temperature ＞ target setting temperature value in compartment, enters refrigeration mode, that is, system opened by compressor of air conditioner
Cold, air-conditioning draught fan full-speed operation；If temperature≤target setting temperature value in compartment, enter air vent mode, that is, compressor of air conditioner is not
Work, air-conditioning interior circulation is divulged information；
When temperature in temperature≤compartment outside compartment, now enter external ventilation pattern, that is, compressor of air conditioner does not work, empty
Adjust outer circulation ventilation, reduce temperature in compartment with cooler air outside compartment.
So, no matter being manual mode or automatic mode, refrigeration control strategy does not also change.
In addition, do not carry out heating also do not freezed when, vehicle can be aerated, as shown in Figure 10, this box
Figure is shown in the input and output under " ventilation " pattern.Control logic is described as follows:
When temperature≤15 DEG C in compartment, air vent mode is inner ventilation；
When temperature outside 15 DEG C of temperature ＞, and temperature ＞ compartment in compartment in compartment, then enter inner-outer circulation air vent mode
(first outer circulation carries out interior circulation 30 minutes in 10 minutes again, then continues to outer circulation 10 minutes, so circulates) is in compartment
Outer temperature is identical；When temperature outside 15 DEG C of temperature ＞, and temperature≤compartment in compartment in compartment, air vent mode is inner ventilation.
It should be noted that this air vent mode is an independent control model, with above-mentioned heating control and refrigeration control
Separate.
In above-described embodiment, two temperature thresholds are set, and one is heating temperature threshold value, and another is cryogenic temperature threshold
Value, when temperature is less than or equal to this heating temperature threshold value in compartment, carries out heating control；When in compartment temperature be more than or
During equal to this cryogenic temperature threshold value, carry out refrigeration control, and give a kind of specific refrigeration control strategy.But, this
Bright be not limited to this refrigeration control strategy, as other embodiments, can also using existing central existing other refrigeration
Control strategy, or the present invention only carries out heating control, does not carry out refrigeration control.
In above-described embodiment, on the basis of control panel, temperature-controlled process is illustrated, but due to controlling
Panel is not the emphasis of the present invention, and the present invention focuses on temperature-controlled process, so, the temperature control side that the present invention provides
