Appeal No. 2006-1228
Application No. 09/802,982
1. A device for heating and/or air conditioning the
passenger compartment of a motor vehicle, comprising an
engine-cooling loop in which a heat-carrying fluid
circulates for taking up heat from the engine and
returning the heat to an air heater; a heat-pump loop
in which a refrigerant fluid circulates, said heat-pump
loop containing a compressor, a first evaporator
constituting a cold source of the heat jump at which
the refrigerant fluid takes up heat from the
surroundings, and a first condenser constituting a hot
source of the heat pump at which the refrigerant fluid
gives up heat, the first condenser being integrated
into the engine-cooling loop upstream of the air
heater, the device further comprising an air-
conditioning branch containing a second condenser and a
second evaporator, the air-conditioning branch having
an upstream end connected to the heat-pump loop
downstream of the compressor, and a downstream end
connected to the heat-pump loop upstream of the
compressor, and a switching device making it possible
to make the refrigerant fluid circulate either in the
air-conditioning branch, or in the heat-pump branch, is
[sic: in] such a way as to form a heat-pump loop.
