Abstract

A system for supplying air to first and second regions of a vehicle passenger compartment, has a first fan, a heater device, and first and second air conduits. The heater device has a first air inlet and outlet for air from the first fan and a second air inlet and outlet for recirculating air within the passenger compartment. The first and second outlets of the heater device supply air through the first and second air conduits to the first and second regions of the said vehicle. The second air conduit is connected to said second air outlet of said heater device via a second fan operable in use to selectively supply air through the second conduit to the second region of the vehicle.

Claims

1. A vehicle, comprising:

a passenger compartment having at least a first and a second region;

a heater device having, a primary air circuit, said primary air circuit having a first and second air inlets and first and second air outlets, air at the first inlet may pass substantially only to the first outlet and air at the second inlet may pass substantially only to the second outlet, said primary air circuit further including an evaporator such that air flow through the primary circuit crosses said evaporator;

a first fan having an air inlet and a fan outlet, said fan outlet being coupled to said first inlet of said heater device for supplying air thereto,

a secondary air circuit having an auxiliary inlet duct and an auxiliary inlet, air flow in said inlet duct impeded from fluid communication with air flow of said first and second inlets of said primary air circuit such that said auxiliary inlet duct is disposed to receive air from within said passenger compartment for recirculation of air in said passenger compartment so that air flow through said secondary air circuit does not cross said evaporator;

first and second air conduits coupled to first and second outlets of the heater device for supplying air to said first and second regions of the vehicle;

a second fan having an inlet and an outlet, said outlet of the second fan being coupled to the second conduit and said inlet of the second fan being coupled to the second outlet of the heater device whereby the second fan is operable in use to selectively supply air through said second conduit to said second region of the vehicle; and

said auxiliary inlet disposed within said passenger compartment, said auxiliary inlet being connected to the fan inlet of the second fan, whereby air from said passenger compartment may be recirculated by the second fan.

2. The vehicle according to claim 1, wherein said second region is a rear region and said first region is a front region of the passenger compartment.
