Vehicular air-conditioning and heating system

Claim 2

In combination with a vehicle propelled by a prime mover power plant of the boiler-turbine-condenser type, a system for heating or cooling the interior of the vehicle comprising: a heat exchange coil positioned within said vehicle; means for establishing a forced circulation of air over said coil; first selectively operable means for conducting hot fluid from the exhaust of said turbine to said coil whenever heating is desired; second selectively operable means for expanding liquid from said condenser through said coil; means for returning fluid from said coil to said condenser; first and second auxiliary turbines; a compressor driven by said first auxiliary turbine and connected between the outlet of said coil and said condenser; and a pump driven by said second auxiliary turbIne and connected between said condenser and said boiler.

Claim 3

The combination defined by claim 1 in which said auxiliary turbines are connected in parallel with each other and with the power turbine.

Claim 4

The combination defined by claim 1 in which said auxiliary turbines are connected in series with each other and in parallel with the power turbine.

Claim 5

In combination, a vehicular propulsion unit power plant of the vapor cycle type and an air-conditioning system, said plant and system using the same working fluid, comprising: a. a boiler for supplying hot vapor; b. a power turbine for driving the vehicle connected to said boiler; c. a first condenser connected to the exhaust of said power turbine; d. a boiler feed pump connected between said condenser and said boiler; e. a first auxiliary turbine also connected to said boiler and said condenser and arranged to drive said boiler feed pump; f. a heat exchange coil; g. means establishing an airflow over said coil; h. a second auxiliary turbine connected between said boiler and said condenser; i. a compressor arranged to be driven by said second auxiliary turbine; j. a second condenser having its outlet connected to the outlet of said first condenser; k. means connecting said compressor between the outlet of said heat exchange coil and the inlet of said second condenser; l. and valve means selectively operable to admit hot vapor from said power turbine exhaust to the inlet of said heat exchange coil whenever heating is desired and for expanding liquid from the outlet of said condenser into the inlet of said heat exchange coil whenever cooling is desired.

Claim 6

In combination, a vehicular propulsion unit power plant of the vapor cycle type and an air-conditioning system, said plant and system using the same working fluid, comprising: a. a boiler for supplying hot vapor; b. a power turbine for driving the vehicle connected to said boiler; c. a first condenser connected to the exhaust of said power turbine; d. a boiler feed pump connected between said condenser and said boiler; e. a first auxiliary turbine also connected to said boiler and said condenser and arranged to drive said boiler feed pump; f. a heat exchange coil; g. means establishing an airflow over said coil; h. a second auxiliary turbine connected between said boiler and said condenser; i. a compressor arranged to be driven by said second auxiliary turbine; j. a second condenser having its outlet connected to the outlet of said first condenser; k. means connecting said compressor between the outlet of said heat exchange coil and the inlet of said second condenser; l. and valve means selectively operable to admit hot vapor from said power turbine exhaust to the inlet of said heat exchange coil whenever heating is desired and for expanding liquid from the outlet of said condenser into the inlet of said heat exchange coil whenever cooling is desired.

Claim 7

The combination defined by claim 4 including a recuperator heat exchanger having a fluid path connected between said boiler feed pump and said boiler, and a second fluid path connected between the exhaust of said power turbine and the inlet of said first condenser.

Claim 8

The combination defined by claim 5 in which said valve means connects the inlet of said heat exchange coil to a point between said recuperator and said first condenser when heating is desired.

Claim 9

The combination defined by claim 5 in which said valve means connects the inlet of said heat exchange coil directly to the exhaust of said power turbine when heating is desired.

Claim 10

The combination defined by claim 4 in which said auxiliary turbines are connected in parallel with each other and with said power turbine.

Claim 11

The combination defined by claim 4 in which said auxiliary turbines are connected in series with each other and in parallel with said power turbine.
