Abstract: An onboard air conditioning device wherein the heating capability of air conditioning is improved, and gas is prevented from flowing into the vehicle interior even in the unlikely event that gas is produced by a battery. In this device, one end of an air flow channel is connected to an air conditioning unit for blowing temperature-regulated air into a vehicle interior, and the other end opens into the vehicle interior. The air flow channel draws air into the vehicle interior from the opening, the intake air is passed through a battery and heated by heat exchange, and the air is then sent to the air conditioning unit. The air conditioning unit sends the air from the air flow channel to a sensible heat exchanger, and after this air undergoes heat exchange with air taken in from another channel, the air is exhausted out of the vehicle interior.

Abstract: 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).

Abstract: An air-conditioner ECU sets the maximum flowrate or a set flowrate which is less than the maximum flowrate as a required flowrate Vr based on outside air temperature when a DEF mode is selected, and requires that coolant be circulated (steps 100 to 110). Also, when the coolant temperature Tw during heating is between a set temperature TS3 and a set temperature TS1, circulation of coolant at the minimum flowrate is required (steps 134, 130, 132). When a blower fan is stopped when the coolant temperature is equal to or less than the set temperature TS3 and a fresh air mode is selected, the circulation of coolant at the minimum flowrate is required when the vehicle speed Sv is above a set vehicle speed (steps 134 to 146). Cool air is prevented from being blown out of an air outlet and heating of the coolant is promoted by suppressing the speed of an electric pump while maintaining the ability to prevent fogging.
