In refrigeration operation, control unit 64 regularly determines whether to meet air-conditioning change condition.Meet in refrigeration operation In the case of air-conditioning change condition, control unit 64 is so that from the sky conveyed to air-conditioning flow path 40 in the air that air blower 22 is sent out The amount of gas reduces and the increased mode of amount of the air conveyed to first exhaust flow path 48 is made to control air distribution control door 34.For example, Control unit 64 can also be controlled to air distribution door 34 send be used for so that the amount of the air conveyed to air-conditioning flow path 40 with to first row The ratio between amount of air that air-flow road 48 conveys is 1 to 2 (33.3%：66.7%) mode indicates the signal of aperture adjustment.

Figure 10 shows to meet the air flowing after air-conditioning change condition in refrigeration operation.The sky sent out from air blower 22 Air-flow is to air-conditioning flow path 40 and first exhaust flow path 48 this two side, but the amount for flowing to the air of air-conditioning flow path 40 becomes than meeting Amount before air-conditioning change condition is few.On the other hand, flowing to the amount of the air of first exhaust flow path 48 becomes to become than meeting air-conditioning Amount before more condition is more.That is, after meeting air-conditioning change condition, flows to the amount of the air of air-conditioning flow path 40 and flow to first The difference of the amount of the air of exhaust flow path 48 becomes larger.As a result, being blown from shoulder after being cooled down by the heat utilization face 16 of Poltier module 14 The amount of the cold wind of 24 blowout of outlet becomes fewer than the amount before meeting air-conditioning change condition.

It is reduced by the amount for the air for making to flow in air-conditioning flow path 40 like this, Poltier module 14 can be further increased Cooling effect of the heat utilization face 16 to the air flowed in air-conditioning flow path 40.Also, by making to flow in first exhaust flow path 48 The amount of dynamic air increases, and the thermal discharge efficiency of the heat removal surface 18 of Poltier module 14 increases and peltier effect is promoted, Neng Goujin One step cools down heat utilization face 16.Thereby, it is possible to from shoulder blow-off outlet 24 send out compared to meet air-conditioning change condition it Before for the lower air of temperature.That is, air-conditioning device 10 can realize low wind speed and strong cold refrigeration, relaxing for air-conditioning can be realized Adaptive improves.

Meet the sky in the action and air-conditioning device 10 of the air-conditioning device 10 before air-conditioning change condition in heating operation Flow of air in conjunction with Fig. 4 as described.Can also be, before meeting air-conditioning change condition, the control of air-conditioning device 10 Portion 64 to air distribution control door 34 send be used for so as to air-conditioning flow path 40 convey air amount with it is defeated to first exhaust flow path 48 The ratio between amount of air sent is 1 to 1 (50%：50%) mode indicates the signal of aperture adjustment.

In heating operation, control unit 64 regularly determines whether to meet air-conditioning change condition.Meet in heating operation In the case of air-conditioning change condition, control unit 64 is so that from the sky conveyed to air-conditioning flow path 40 in the air that air blower 22 is sent out The amount of gas reduces and the increased mode of amount of the air conveyed to first exhaust flow path 48 is made to control air distribution control door 34.For example, Control unit 64 can also be controlled to air distribution door 34 send be used for so that the amount of the air conveyed to air-conditioning flow path 40 with to first row The ratio between amount of air that air-flow road 48 conveys is 1 to 2 (33.3%：66.7%) mode indicates the signal of aperture adjustment.

Figure 11 shows to meet the air flowing after air-conditioning change condition in heating operation.The sky sent out from air blower 22 Air-flow is to air-conditioning flow path 40 and first exhaust flow path 48 this two side, but the amount for flowing to the air of air-conditioning flow path 40 becomes than meeting Amount before air-conditioning change condition is few.On the other hand, flowing to the amount of the air of first exhaust flow path 48 becomes to become than meeting air-conditioning Amount before more condition is more.That is, after meeting air-conditioning change condition, flows to the amount of the air of air-conditioning flow path 40 and flow to first The difference of the amount of the air of exhaust flow path 48 becomes larger.As a result, being blown from foot after being heated by the heat utilization face 16 of Poltier module 14 The amount of the warm air of 28 blowout of outlet becomes fewer than the amount before meeting air-conditioning change condition.

It is reduced by the amount for the air for making to flow in air-conditioning flow path 40 like this, Poltier module 14 can be further increased Heating effect of the heat utilization face 16 to the air flowed in air-conditioning flow path 40.Also, by making to flow in first exhaust flow path 48 The amount of dynamic air increases, and the thermal discharge efficiency of the heat removal surface 18 of Poltier module 14 increases and peltier effect is promoted, Neng Goujin One step heats heat utilization face 16.Thereby, it is possible to from foot's blow-off outlet 28 send out compared to meet air-conditioning change condition it Before for the higher air of temperature.That is, in air-conditioning device 10, it can realize low wind speed and heating warm by force, can realize sky The comfort of tune improves.

In addition, in the car, 12V supplies in general are carried out to electric component, loss is will produce in transformation, energy A part is lost in the form of heat.In the air-conditioning device 10 of the 4th embodiment, do not change to Poltier module 14 and air blast The application voltage of machine 22, and the aperture that door 34 is controlled by air distribution adjusts to adjust air-conditioner temperature.It need not be used to adjust as a result, The transformation of air-conditioner temperature can realize effective use of energy.In addition it is possible to cut down the cost involved by transformer.

(the 5th embodiment)

First, the summary of the 5th embodiment is described.It had described in the fourth embodiment, in the car, generally For to electric component carry out 12V supplies.It is changed to Poltier module 14 or air blower when in order to adjust the temperature in air-conditioning When the voltage of 22 applications, loss is will produce, a part for energy is lost in the form of heat.

For example, in above-mentioned patent document 3, in order to adjust the blowout temperature at seat conditioning, need change to air-supply The voltage that a side or two sides in machine and Peltier's element apply.In transformation, loss is will produce, a part for energy is with heat Form is lost in.

Therefore, the air-conditioning device 10 of the 5th embodiment does not change the electricity to Poltier module 14 and the application of air blower 22 Pressure, but be adjusted by the aperture of the door of the air flow circuit to being set in device, to change the air quantity and temperature of air-conditioning.

In addition, in previous in-vehicle air conditioner, detected based on the temperature sensor being set to everywhere in vehicle Temperature information, to control the air quantity and temperature of air-conditioning.But it is not the vehicle of confined space in the compartment as scheduled bus In, the air outside vehicle is flowed into vehicle always, therefore the airconditioning control based on temperature information is not necessarily best sometimes.5th Air-conditioning device 10 involved by embodiment controls the air quantity of air-conditioning using the duration of runs of vehicle 100 and car speed as parameter And temperature.

In the following, explaining the structure of the air-conditioning device 10 involved by the 5th embodiment in detail.In the 5th embodiment, Air quantity when refrigeration operation and characterized by the control of temperature, as the pattern of refrigeration operation, be provided with " maximum quantity of wind pattern ", " middle air quantity/middle chill formula ", " low air quantity/strong chill formula " these three patterns.Under maximum quantity of wind pattern, the sky that is not cooled by Gas is blown out with maximum quantity of wind from shoulder blow-off outlet 24.

Under middle air quantity/middle chill formula, the air of middle degree is cooled to the air quantity of middle degree from shoulder blow-off outlet 24 Blowout.The desired value of blowout temperature when " middle air quantity/middle chill formula " is for example set to lower by 2 than the temperature outside vehicle 100 It spends to 7 degree of temperature.The desired value can also be such as the first mesh of 2 degree to 5 degree of temperature lower than temperature outside vehicle 100 It is set with being refined as scale value and the second desired value as 5 degree to 7 degree of temperature lower than temperature outside vehicle 100 It is fixed.In this case, vehicle 100 can also also have the temperature sensor (not shown) of the temperature outside detection vehicle 100.

Under low air quantity/strong chill formula, it is cooled to the coldest air and is blown out from shoulder blow-off outlet 24 with weak air quantity. The desired value of blowout temperature when " low air quantity/strong chill formula " be for example set to 10 degree lower than temperature outside vehicle 100 with On temperature.

Control unit 64 shown in Fig. 2 according to the speed of vehicle 100 come by the operation mode of refrigeration operation middle air quantity/in it is cold It is switched between pattern and low air quantity/strong chill formula.Alternatively, it is also possible to be, the root under middle air quantity/middle chill formula of control unit 64 It will be set between first object value and the second desired value according to the speed of vehicle 100 and further switch over.For example, it is also possible to It is that, in the case where the speed of vehicle 100 is more than defined threshold value (for example, when 20km/), control unit 64 will blow out the mesh of temperature Scale value is set as first object value, and the speed in vehicle 100 is below for defined threshold value (for example, when 20km/), control The desired value for blowing out temperature is set as the second desired value by portion 64 processed.Specifically, control unit 64 according to the speed of vehicle 100 come Adjust air distribution control door 34, wind path switching door 36 and the aperture for returning to control door 38.

Control unit 64 according to the duration of runs of vehicle 100 come by the operation mode of refrigeration operation maximum quantity of wind pattern in It is switched between air quantity/middle chill formula.Specifically, control unit 64 switched according to the duration of runs of vehicle 100 it is whether right Poltier module 14 applies voltage.Also, control unit 64 adjusts air distribution control door 34 and wind according to the duration of runs of vehicle 100 Road switches the aperture of door 36.

When refrigeration operation under middle air quantity/middle chill formula, control unit 64 applies voltage to Poltier module 14, and with Air distribution, which is controlled, to the mode of air-conditioning flow path 40 and this two side conveying air of first exhaust flow path 48 controls door 34.On the other hand, exist When refrigeration operation under maximum quantity of wind pattern, control unit 64 stops applying voltage to Poltier module 14, and so as to air-conditioning The mode more than amount when the amount for the air that flow path 40 conveys is than middle air quantity/middle chill formula controls air distribution control door 34.

Specifically, the storage part (not shown) of air-conditioning device 10 can also keep preserving the maximum quantity of wind pattern that indicates, Air distribution control door 34 when each pattern in middle air quantity/middle chill formula, low air quantity/strong chill formula, returns to control at wind path switching door 36 The table of the information of the aperture of door 38 processed.The cooling operation pattern that control unit 64 can also be determined with reference to the table and should currently be executed The aperture of corresponding each door.Then, control unit 64 can also be used to indicate the aperture of each door by being sent to the actuator of each door Signal control the bifurcation approach of the air at each door.

In addition, the storage part (not shown) of air-conditioning device 10, which can also keep preserving, indicates maximum quantity of wind pattern, apoplexy The target of the temperature of the air of slave shoulder blow-off outlet 24 blowout when each pattern in amount/middle chill formula, low air quantity/strong chill formula The table of the information of value.Control unit 64 can also be with reference to the table, to determine air distribution control door 34, wind path switching door 36 and return to control The aperture of door 38 processed so that the information of the temperature received from the temperature sensor 26 for being set to shoulder blow-off outlet 24 is (from shoulder The temperature for the air that blow-off outlet 24 is blown out) close to desired value.Then, control unit 64 can also be by sending to the actuator of each door The signal of the aperture of each door is used to indicate to control the bifurcation approach of the air at each door.

No matter the pattern of refrigeration operation is in maximum quantity of wind pattern, middle air quantity/middle chill formula, low air quantity/strong chill formula Which pattern, in the case where applying voltage to Poltier module 14 or air blower 22, control unit 64 is not to application electricity Pressure changes.For example, the pattern regardless of refrigeration operation, control unit 64 all by from the accumulator of vehicle 100 or battery (not Diagram) supply standard voltage (for example, 12V) without change into Poltier module 14 and air blower 22 at least one Side applies.
