专利汇可以提供Apparatus for heating and cooling a vehicle passenger compartment专利检索，专利查询，专利分析的服务。并且An apparatus for heating and cooling the passenger compartment of a motor vehicle quickly brings the temperature of the compartment to the desired level and the temperature is thereafter maintained at a constant level without the use of blowers. The apparatus includes first and second heat exchangers which are separately or in combination selectively connected for establishing a heat-exchanging relationship between a third heat exchanger and the first and second heat exchangers. The third heat exchanger has a relatively large surface area and is located within the vehicle passenger compartment. The first and second heat exchanger rapidly bring the temperature of the passenger compartment to the desired level with the assistance of blowers, adjacent to these two heat exchangers, which blow the conditioned air into the passenger compartment. After the desired temperature has been reached, the fans are turned off and the temperature in the compartment is maintained by radiation by the third heatexchanger and at least one of the other two heat exchangers.，下面是Apparatus for heating and cooling a vehicle passenger compartment专利的具体信息内容。

权利要求

1. Apparatus for heating and cooling a space, particularly the passenger compartment of a motor vehicle, comprising in combination first heat exchanger means for conditioning air by heating the same; second heat exchanger means for conditioning air by cooling the same; blower means associated with and positioned in proximity to said first and second heat exchanger means and operative for blowing conditioned air into said space so that the temperature of air in said space can be rapidly brought to a desired temperature; third heat exchanger means arranged for exchanging heat with the air in said space; circuit means connecting said third heat exchanger means with said first and second heat exchanger means; and control means for selectively establishing a heat-exchanging relationship via said circuit means between said third heat exchanger means and at least one of said first and second heat exchanger means to cause said third heat-exchanger means to keep the air in said space at a desired temperature when said blower means is not in operation.

2. Apparatus as defined in claim 1, wherein said first and second heat exchanger means have output circuits connected to said control means which are adapted to conduct heat exchange mediums, and said third heat exchanger means has an input circuit connected to said control means which is adapted to carry said mediums, said input and output circuits forming part of said circuit means, said medium flowing in said input circuit having a temperature which corresponds to that of one of said first and second heat exchanger means with which said third heat exchanger means established a heat-exchanging relationship.

3. Apparatus as defined in claim 2, further comprising aT least one pump means in one of said circuit means for circulating said mediums.

4. Apparatus as defined in claim 2, wherein said control means includes valve means for selectively connecting said input circuit to one of said output circuits.

5. Apparatus as defined in claim 4, further comprising at least one pump means arranged between said third heat exchanger means and said valve means for circulating said mediums.

6. Apparatus as defined in claim 1, wherein said third heat exchanger has a relatively large surface area and is located within the space.

7. Apparatus as defined in claim 6, wherein said space is the passenger compartment of a motor vehicle, and said heat exchanger means is located on the roof of the compartment.

8. Apparatus as defined in claim 1, wherein said space is the passenger compartment of a motor vehicle having an internal combustion engine, and said first heat exchanger means is connected to the cooling system, whereby said first heat exchanger means is heated by the cooling system of the internal combustion engine.

9. Apparatus as defined in claim 1, wherein said space is the passenger compartment of a motor vehicle having an internal combustion engine, and said first heat exchanger means is connected to the exhaust system, whereby said first heat exchanger means is heated by the escaping hot exhaust gases from the internal combustion engine.

10. Apparatus as defined in claim 1, wherein said apparatus further comprises an air conditioner having a cooling circuit, said second heat exchanger unit being connected in series with said cooling circuit.

11. Apparatus as defined in claim 1, wherein said first and second heat exchange means are located in the region of said space, whereby heat transfer may take place between said first and second heat exchanger means and said space.

12. Apparatus as defined in claim 1, wherein said first, second and third heat exchanger means are connected in series, wherein said circuit means includes a bypass circuit means across each of said first and second heat exchanger means for bypassing the heat exchanging mediums which bring heat to and carry heat away from said first and second heat exchanger means respectively; and wherein said control means comprises valve means for opening and closing said bypass circuits, whereby the heat exchange between said third heat exchanger means and said first and second heat exchanger means is determined by the adjustment of the valve means in the bypass circuit means.

13. Apparatus as defined in claim 1, wherein said blower means comprises a first blower associated with and positioned in proximity to said first heat exchanger means for blowing heated air into said space, and a second blower associated with and positioned in proximity to said second heat exchanger means for blowing cooled air into said space.
