Description
- The present invention relates to a vehicle air conditioner.
- Japanese Unexamined Patent Application Publication No. 10-35268 discloses a vehicle air conditioner including a waste heat collector, a radiator, a peltier module, and a heat medium passage through which water as a heat medium is circulated.
- The waste heat collector functions to collect waste heat from a vehicle power source such as an electric motor. The peltier module has a peltier device with a first and a second surface one of which serves as heat releasing surface and the other of which serves as heat absorbing surface, a first heat exchanger thermally coupled to the first surface of the peltier device, and a second heat exchanger thermally coupled to the second surface of the peltier device. The heat medium passage connects the waste heat collector, the radiator, and the second heat exchanger of the peltier module.
- In the air conditioner, air conditioning of vehicle passenger compartment is done by switching the heat releasing and absorbing surfaces of the peltier device and also changing the water flow path in the heat medium passage.
- Specifically, when heating the passenger compartment, the peltier device is operated so that the first surface serves as the heat releasing surface and the second surface serves as the heat absorbing surface. The waste heat collector is connected to the second heat exchanger, while the second heat exchanger and the waste heat collector are disconnected from the radiator. Water flowing in the heat medium passage is heated by the heat in the waste heat collector. Heat of the water is absorbed through the second heat exchanger in the second surface of the peltier device. The heat thus absorbed is radiated from the first heat exchanger into the surrounding air. Then the heated air is supplied to the passenger compartment, so that heating of the passenger compartment is accomplished.
- When cooling the passenger compartment, the peltier device is operated so that the first surface serves as the heat absorbing surface and the second surface serves as the heat releasing surface. The radiator is connected to the second heat exchanger, while the second heat exchanger and the radiator are disconnected from the waste heat collector. Heat is absorbed through the first heat exchanger in the first surface of the peltier device and the air around the first exchanger is cooled. The cooled air is supplied to the passenger compartment, so that cooling of the passenger compartment is accomplished. The water in the heat medium passage is heated by the second heat exchanger to which heat is released from the peltier device, and then cooled in the radiator by heat exchange with the air outside the passenger compartment.
- Another known air conditioner is disclosed in Japanese Unexamined Patent Application Publication No. 2010-195287. The air conditioner includes a radiator, a first peltier module, a second peltier module, and a heat medium passage through which water is circulated. The heat medium passages connects the radiator, the first peltier module and the second peltier module.
- When heating the passenger compartment by the air conditioner, the first peltier module is operated so as to absorb heat from the water flowing in the heat medium passage and also release heat to the surrounding air. The heated air is supplied to the passenger compartment, so that heating of the passenger compartment is accomplished.
- When cooling, the second peltier module and the radiator are operated so that the second peltier module releases heat to the water flowing in the heat medium passage and also absorbs heat from the surrounding air. The cooled air is supplied to the passenger compartment, so that cooling of the passenger compartment is accomplished.
- When dehumidifying, the first and second peltier modules and the radiator are operated. Air is cooled and dehumidified by the second peltier module, and then the cooled air is heated by the first peltier module. The air at appropriately adjusted temperature is supplied to the passenger compartment, so that dehumidifying of the passenger compartment is accomplished.
- The air conditioner disclosed in the publication No. 10-35268 is complex in structure and large in size, which is disadvantageous in the installation in a vehicle. In addition, since the air cooled by the peltier module cannot be re-heated, the dehumidification causes a decrease in the efficiency of heating the compartment.
- In the air conditioner disclosed in the publication No. 2010-195287, on the other hand, although the dehumidification does not necessarily cause a decrease in the efficiency of cooling the compartment, the air conditioner requires an additional radiator for releasing heat from a vehicle power source. The provision of plural radiators results in an increased size of the air conditioner, which prevents easy installation of the air conditioner in a vehicle.
- The present invention is directed to providing a vehicle air conditioner that allows efficient air conditioning of a passenger compartment and easy installation in a vehicle.
- In accordance with an aspect of the present invention, a vehicle air conditioner for a passenger compartment of a vehicle includes a power source for driving the vehicle, a radiator provided outside the passenger compartment, a heat medium passage through which heat medium is circulated between the power source and the radiator, a first peltier module having a first peltier device and a first heat exchanger, and a second peltier module having a second peltier device and a second heat exchanger. The first peltier device has a first surface and a second surface, one of the first surface and the second surface serves to release heat, the other of the first surface and the second surface serves to absorb heat. The first heat exchanger is thermally coupled to the first surface. The second peltier device has a first surface and a second surface, one of the first surface and the second surface serves to release heat, the other of the first surface and the second surface serves to absorb heat. The second heat exchanger is thermally coupled to the first surface. The heat medium passage is thermally coupled to the second surface of the first peltier device and the second surface of the second peltier device.

Themain portion 31 of theduct 15 hasholes tube 9 is inserted. - In the above-described vehicle air conditioner, while the
engine 3 is operating, the pump P1 and thefan 5C are operated by the controller so that engine coolant is circulated through thetubes FIG. 3 . Engine coolant heated by the waste heat of theengine 3 flows from theoutlet 3B of theengine 3, flowing through thetube 7 and then into theinlet 5A of theradiator 5. Heat exchange occurs between the engine coolant flowing in theradiator 5 and the air around theradiator 5, so that the heat of the engine coolant is radiated by the aid of thefan 5C into the air outside the passenger compartment. The engine coolant thus cooled in theradiator 5 then flows from theoutlet 5B of theradiator 5 through thetube 9 and into theinlet 3A of theengine 3, cooling theengine 3. While theengine 3 is operating, the air conditioner of the present embodiment provide heating, cooling and dehumidifying of the passenger compartment of the vehicle as described below. - When heating the passenger compartment, the
first peltier device 17 of thefirst peltier module 11 is operated by the controller. Theflapper 37 and thefan 31A are also operated by the controller so that themain portion 31 of theduct 15 is connected to thebranch portion 33 but disconnected from thebranch portion 35, as shown inFIG. 3 , and indoor air is introduced into themain portion 31. In this case, thesecond surface 17B or heat absorbing surface of thefirst peltier device 17 absorbs heat from the engine coolant flowing in thetube 9, while thefirst surface 17A or heat releasing surface of thefirst peltier device 17 releases heat to thefirst fin 19. As a result, thefirst fin 19 is heated, and the indoor air in contact with the heatedfirst fin 19 in themain portion 31 is heated, accordingly. The indoor air existing in the passenger compartment has a higher temperature than the outdoor air, and the indoor air is efficiently heated by thefirst fin 19. Heated indoor air is supplied by thefan 31A through theduct 15 to the passenger compartment. In this way, heating of the passenger compartment is done. - The engine coolant flowing in the
tube 9 and cooled by thefirst peltier device 17 flows into theengine 3 through itsinlet 3A to be used to cool theengine 3. In the air conditioner of the present embodiment wherein theengine 3 is located downstream of thefirst peltier module 11 as seen in the engine coolant flowing direction in thetubes engine 3 can be cooled by the engine coolant cooled by thefirst peltier device 17 as well as by theradiator 5. In other word, theengine 3 can be efficiently cooled by utilizing the waste heat of thefirst peltier module 11 during the heating operation of the air conditioner. - When cooling the passenger compartment, the
second peltier device 27 of thesecond peltier module 13 is operated, and theflapper 37 and thefan 31A are operated as in the case of the above heating operation so that indoor air is introduced into themain portion 31 of theduct 15. In this case, thesecond surface 27B of thesecond peltier device 27 releases heat to the engine coolant flowing in thetube 9, while thefirst surface 27A of thesecond peltier device 27 absorbs heat from thesecond fin 29. As a result, thesecond fin 29 is cooled, and the indoor air in contact with thesecond fin 29 in themain portion 31 is cooled. The indoor air existing in the passenger compartment has a lower temperature than the outdoor air, and the indoor air is efficiently cooled by thesecond fin 29. Cooled indoor air is supplied to the passenger compartment, so that cooling of the passenger compartment is done. The engine coolant flowing in thetube 9 and receiving heat from thesecond peltier device 27 is used to cool theengine 3 and then cooled by theradiator 5. That is, the waste heat of thesecond peltier module 13 during the cooling operation is released along with the waste heat of theengine 3 into the air outside the passenger compartment. - When dehumidifying the passenger compartment, both of the first and
second peltier modules FIG. 4 . Theflapper 37 and thefan 31A are also operated so that themain portion 31 is connected to thebranch portion 35 but disconnected from thebranch portion 33 and the outdoor air is introduced into themain portion 31. In this case, the outdoor air cooled by thesecond fin 29 and dehumidified is in turn heated by thefirst fin 19 to an appropriate temperature. The outdoor air which has a lower humidity than the indoor air is efficiently cooled and dehumidified by thesecond fin 29. The outdoor air adjusted at an appropriate temperature is supplied to the passenger compartment for dehumidifying of the passenger compartment, as well as for appropriate air-conditioning of the passenger compartment. The engine coolant releasing heat to thefirst peltier device 17 and receiving heat from thesecond peltier device 27 while flowing in thetube 9 is introduced into theengine 3 through itsinlet 3A and used to cool theengine 3. When there is no need to heat the dehumidified outdoor air, no operation of the firstpettier module 11 is performed. - In the vehicle air conditioner of the present embodiment, heating and cooling of the passenger compartment can also be accomplished by using heated outdoor air and cooled outdoor air, respectively, which makes it easy to keep the humidity of the passenger compartment during the heating and cooling operation when the outdoor air has a lower humidity than the indoor air. Dehumidifying of the passenger compartment can also be accomplished by using the dehumidified indoor air. In a weather condition that the outdoor air has a higher humidity than the indoor air, the use of such dehumidified indoor air allows efficient dehumidifying of the passenger compartment and makes it easy to keep the humidity of the passenger compartment by circulating the indoor air between the
main portion 31 of theduct 15 and the passenger compartment. Theflapper 37 may be positioned so that both of thebranch portions main portion 31 of theduct 15, which allows air conditioning of the passenger compartment using the outdoor air and the indoor air mixed together in a desired mixing ratio. - As described above, according to the vehicle air conditioner of the present embodiment, there is no need to change the flow path of the engine coolant flowing in the
tubes engine 3 is connected to thetubes tubes second peltier modules engine 3 are transferred by the engine coolant and radiated from theradiator 5 into the air outside the passenger compartment. Thus, the air conditioner of the embodiment requires no additional radiator to cool theengine 3, which results in a smaller size of the air conditioner. - Thus, the vehicle air conditioner of the present embodiment allows efficient air conditioning of the passenger compartment and easy installation of the air conditioner in a vehicle.
- Particularly in the air conditioner of the present embodiment wherein
second peltier module 13 is provided downstream of thefirst peltier module 11 as seen in the engine coolant flowing direction in thetube 9, since thesecond peltier device 27 releases heat to the engine coolant that has been cooled by thefirst peltier device 17 when dehumidifying the vehicle passenger compartment, a larger amount of heat is absorbed in the heat absorbing surface of thesecond peltier device 27 and hence thesecond fin 29 is sufficiently cooled. The outdoor air is cooled efficiently and dehumidified sufficiently by such cooledsecond fin 29, resulting in efficient dehumidification of the passenger compartment. The cooled outdoor air can be re-heated by thefirst fin 19, which does not cause a decrease in the efficiency of air conditioning of the passenger compartment. - In the air conditioner of the present embodiment, the first and
second peltier modules duct 15 that is in communication with the passenger compartment. Theduct 15 is provided with theflapper 37 which allows selective supply of the outdoor air or the indoor air to the passenger compartment. Efficient air conditioning of the passenger compartment is accomplished by heating, cooling or dehumidifying the outdoor or the indoor air selected as required. - It is to be understood that the present invention is not limited to the above-described embodiments, but it may be modified in various ways without departing from the scope of the invention.
- For example, the engine coolant flowing through the
tubes engine 3 but also to cool any other component such as a battery provided in a vehicle and thermally coupled to thetubes - The number of the
first peltier modules 11 and of thesecond peltier modules 13 may be two or more. The number of thefirst peltier module 11 and the number of thesecond peltier module 13 need not necessarily be the same, but they may be different from each other. - The
first fin 19 and thesecond fin 29 may be replaced by a first heat exchanger and a second heat exchanger, respectively, through which water circulates. In such a case, the water flowing in the first heat exchanger receives heat from thefirst peltier device 17 and hence is heated. Outdoor air or indoor air in themain portion 31 of theduct 15 is heated by heat exchange with such heated water. Similarly, the water flowing in the second heat exchanger releases heat to thesecond peltier device 27 and is cooled. Outdoor air or indoor air in themain portion 31 of theduct 15 is cooled by heat exchange with such cooled water. - The present invention is applicable to an air conditioner for use in an engine powered vehicle, a hybrid vehicle driven by an engine and an electric motor, and an electric vehicle driven by an electric motor.
