A heating system (50) for heating a cabin (2) of an aircraft (1), said heating system including an annular heat exchanger (10) positioned around an exhaust pipe (21) of a turbine engine (20), and through which a heat transfer fluid (14) and ambient air (25) flow. Said heat exchanger (10) is provided with a rear casing situated at an outlet of said heat exchanger (10) and directing the ambient air (25) exiting form said heat exchanger (10) towards said exhaust gas (15) exiting via said exhaust pipe (21). Said exhaust gas (15) then generates a flow of ambient air (25) through said heat exchanger (10) by the Coanda effect. Said ambient air (25) flowing through said heat exchanger (10) is thus heated by convection from said pipe (21), and said heat transfer fluid (14) is heated firstly by radiation from said pipe (21) and secondly by convection between said heat transfer fluid (14) and said ambient air (25).

A waste-heat collection system for a vehicle is provided. The vehicle includes an internal combustion engine and an exhaust manifold via which exhaust manifold hot exhaust gas coming from the internal combustion engine is introduced into an engine-side segment of an exhaust system. The exhaust manifold and/or the engine-side segment of the exhaust system, an exhaust gas turbocharger and/or a catalytic converter are at least partially surrounded by a waste-heat collecting housing. Air contained in the waste-heat collecting housing is heated by waste heat of these components and the heated air is used to charge a latent heat accumulator.

An auxiliary power unit for a vehicle is configured to provide cool or heated air within the vehicle with the main engine off. The auxiliary power unit includes an auxiliary diesel engine that receives fuel from the fuel tank of the vehicle. The auxiliary diesel engine is connected to a hydraulic pump of a hydraulic power system by a first magnetic clutch to provide mechanical power. The hydraulic pump converts the mechanical power to hydraulic power. The hydraulic power system delivers the hydraulic power to a hydraulic compressor drive motor that converts it back to mechanical power. The hydraulic power system is connected to a compressor drive via a second magnetic clutch. The compressor drive provides power to an air conditioner (AC) compressor of the vehicle such that the AC compressor activates while the auxiliary power unit is operating.
