The specific embodiment
Fig. 1 has schematically shown the formation of air conditioning system for vehicle of the present invention.Comprise that in air conditioning system for vehicle as shown in Figure 1 is used to cool off a cooling vessel 6 (refrigerant evaporator) that is blown into air in the car, and the refrigerant circular flow in the refrigerant circulation loop 1 that is used as cooling loop is to cooling vessel 6, thereby cools off this cooling vessel 6.In described refrigerant circulation loop 1, be provided with compressor 2, condenser 3, the desiccant holder 4 of compressed refrigerant and the throttle mechanism 5 that constitutes by expansion valve etc.The blowing engine 9 that air channel 10 (interior environment system) entrance side is provided with becomes through thermoregulator air suction air behind the temperature booster 8 of subcooler 6 and cooling vessel 6 downstream position, and in exhausr port is blown into car.The form of exhausr port has DEF, the VENT that is adjusted to corresponding opening degree, the exhausr port of FOOT isotype.The 7 adjacent settings before temperature booster 8 of air-blending air door.By controlling by the opening degree of regulating air-blending air door 7 with the amount of air of walking around temperature booster 8.Outlet side at cooling vessel 6 is provided with cooler outlet air-temperature pickup 11.Outlet side at temperature booster 8 is provided with heater outlet air-temperature pickup 12, detects air themperature after air is by temperature booster 8 immediately.The heter temperature detecting device can also be set replace above-mentioned heater outlet air-temperature pickup 12, for example detect the cooling water temperature in the temperature booster 8 or detect than cooling water temperature or conduit temperature or temperature booster 8 surface temperatures in (hereinafter will mention) engine cooling water-flow circuit part of the more close temperature booster 8 of release mechanism.
Shown in Fig. 2 and 3, this a/c system is configured to make engine cooling water to flow into temperature booster 8 via a cooling water circulation loop 13 (engine cooling water-flow circuit) circulation.Be positioned on the cooling water circulation loop 13 of temperature booster 8 entrance sides first release mechanism 14 that has out/close valve is set, second release mechanism 15 is arranged at the outlet side of temperature booster 8.By these release mechanisms, can when needed the circulation of engine cooling water from driving engine side direction temperature booster 8 be disconnected.In addition, can be by water valve 16 control engine cooling water magnitude of recruitments at the entrance side of temperature booster 8.
As shown in Figure 2, for temperature booster 8, its intake section and exit portion can be connected with each other logical, form the medium circulation loop, as cold storage material or heat-storage medium, and medium are circulated the engine cooling water in the temperature booster 8.On medium circulation loop 17, be provided for making the pump 18 of medium circulation and being used for storage medium reservoir vessel 19.Preferably be provided for detecting the temperature sensor 20 of on-cycle medium temperature in the temperature booster 8 in the medium circulation loop 17, temperature sensor 20 is set in medium reservoir vessel 19 specifically.Although among the embodiment as shown in Figure 2, the medium reservoir vessel 19 in the medium circulation loop 17 separates mutually with temperature booster 8, yet, also can use as shown in Figure 3 medium reservoir vessel 19 and temperature booster 8 are made one.So just can be when needed be stored in cold storage material circulation in the medium reservoir vessel 19 with predetermined temperature enter with cooling water circulation loop 13 open circuited temperature boosters 8 in, released cold quantity or heat, thus replenish the demand of cooling or heating.
Next the control to air conditioning system for vehicle among the present invention describes.Control of the present invention is specifically when being in maximum refrigerating mode, and (extent of opening of air-blending air door 7 is a MAX COOL state) realizes control when promptly need not the air heating by cooling vessel 6.
Wherein, the meaning of maximum cooling mode time is that (1) is in manual or automatic air condition, when setting air blowing temperature controlling bar and being moved toward cold side, in other words conj.or perhaps when temperature is set to minimum; (2) in automatic air condition, the required air blowing temperature value TaO that calculates is the detected value of cooler outlet temperature or when being lower than this detected value.TaO represents in order to realize the needed air blowing temperature of vehicle interior temperature expected value, and this temperature value is by following Equation for Calculating:
TaO＝f(Tset，Tout，Tin，Rsun，BLV)
Wherein, Tset: vehicle interior temperature setting value Tout: external air temperature
Tin: Inside Air Temperature
Rsun: sunshine amount
BLV: air blower voltage
The control of＜release mechanism 〉
When being in maximum refrigerating mode, the release mechanism 14 and 15 that is positioned at the upstream and downstream position of temperature booster 8 is disconnected, and does not flow in the temperature booster 8 so that cool off the hot water of driving engine.Control hereinafter refers to the control when being in maximum refrigerating mode.
＜depend on the control of running state of the vehicle 〉
When (1) slowing down:
When slowing down, transfer the operation factor or the displacement of big compressor 2.By this adjusting, vehicles whose braking forces can be converted into cold biglyyer.In addition, air-blending air door 7 is shifted to MAX HOT (maximum heat) side, and cold air is introduced in the temperature booster 8, and cold is stored in the cooling water expansion tank in the temperature booster 8.
When (2) stopping:
Shut down the vehicle of function for having idle running, because engine stoping operation, cooling vessel 6 temperature rise.Shut down the vehicle of function for not dallying, by operation factor that reduces compressor or the consumption that displacement improves fuel.Owing in cooling vessel 6, lack thermal source, when vehicle shuts down,, will prevent situation about rising to the temperature that temperature booster 8 occurs as long as the air-blending air door is turned to maximum cold (MAX COOL) state.Therefore, when target cooler outlet air themperature during less than detected cooler outlet air themperature, air-blending air door 7 is moved toward maximum heat (MAX HOT) side, and the cold that is stored in the temperature booster 8 is released.
By this control, replenished the cooling power that lacks.Wherein, the opening degree of air-blending air door 7 according under establish an equation and control.
SW＝1-(TaO-Th)/(Te-Th)
SW: the opening degree of air-blending air door (1: maximum heat MAX HOT, 0: maximum cold MAX COOL)
TaO: the required air themperature that is blown into
Th: air is through the temperature behind the temperature booster
Te: the temperature of air behind subcooler
In addition, when heater outlet air themperature during greater than target cooler outlet air themperature, start the engine or the operation factor or the displacement of compressor increased.
When (3) quickening
When vehicle quickens,, the displacement of compressor is turned down in order to reduce engine load.When driving engine when the state exchange that shuts down is acceleration mode, can control like this, promptly air-blending air door 7 is stayed the maximum heat state, the cold in the temperature booster 8 is released.
(4) vehicle at the uniform velocity travels
If air-blending air door 7 always is in the maximum heat state, then the resistance of air flows will increase.Therefore, air-blending air door 7 is shifted to a position near central authorities, then a part is blown into the inrush of air temperature booster 8 in the car.That is to say that this adjusting can realize making temperature booster 8 always to be cooled.When slowing down, temperature booster 8 is cooled off further, and this adjusting can be used to deal with the idle running of a kind of long period and shut down situation.
＜stop hot air to be blown into the interior control of car 〉
When a kind of common refrigerating mode is converted to maximum refrigerating mode, the inside of temperature booster 8 has been full of hot air.Therefore, if air-blending air door 7 is moved toward the maximum heat condition when slowing down, hot air just is blown in the car.Therefore to detect the surface temperature of temperature booster 8 or the pipe surface temperature of heater outlet or inlet etc., when detected value is predetermined value A or when bigger, with regard to the extent of opening that stops air-blending air door 7 be predetermined value B or bigger value (wherein, opening when maximum heat is called as 1, and the opening when maximum cold is called as 0).By this control, because the opening of air-blending air door 7 does not surpass predetermined value B, the temperature rising value that then is blown into the air in the car is controlled to minimum, and temperature booster 8 can be properly cooled.Wherein, predetermined value B is set as a variable value, and when the detected temperatures of temperature booster during near predetermined value A, this predetermined value B is more near 1.
＜be blown into the control of the amount of air in the car 〉
When air-blending air door 7 being shifted to the maximum heat side, make the amount of air increase that is blown in the car, the resistance in air by-pass passage increases and by increasing resistance the amount of air that is blown in the car is reduced.Therefore, when the opening of air-blending air door increases,, just can stop the amount of air that is blown in the car to reduce if the amount of air accent that supply ventilating fan is blown into is big.
In addition, if air-blending air door 7 is moved toward the maximum heat side when slowing down and air quantity increases, then vehicles whose braking forces can be converted into cold more.
In addition, temperature booster 8 released cold quantities in the process that vehicle shuts down, air-blending air door 7 is moved toward the maximum heat side simultaneously, if increase amount of air in this case, the idle running floor time just may shorten.Therefore, although wherein occurred being blown into the situation that amount of air slightly tails off, when vehicle stops, must stopping to increase the adjusting that supply ventilating fan is sent into amount of air.
May there be above-mentioned several different control in the present invention.Fig. 4 is a time schedule that is illustrated in the various controls of implementing under the different condition.
In addition, as indicated above, the present invention can be applied to the a/c system of pattern of fever again of vehicle.That is to say that the present invention can be applied to so a kind of a/c system, does not have the air-blending air door in this a/c system, all flow in the above-mentioned temperature booster through subcooler and whole air of being blown in the car.
Further, as indicated above, the present invention can be applied to so a kind of air conditioning system for vehicle, comprise a heat pump in this a/c system, this heat pump can make the high-temperature high-pressure refrigerant of compressed machine compression flow into cooling vessel and can be with this cooling vessel as heating arrangement, and stores cold in temperature booster.
