Air-conditioning system for a motor vehicle, and motor vehicle equipped with the system
First Claim
1. An air-conditioning system (7) for a motor vehicle having a passenger compartment (4) and an engine compartment (2), the air-conditioning system (7) comprising at least a first heat exchanger (11) for exchanging heat between external air and a first intermediate fluid, and at least a second heat exchanger (8) for exchanging heat between air within said passenger compartment (4) and a second intermediate fluid;
- said air-conditioning system (7) further comprising a condenser (21) wherein a coolant yields heat to said first intermediate fluid, an evaporator (22) wherein said coolant subtracts heat from said second intermediate fluid, and an internal heat exchanger (19), designed to enable heat exchange between the coolant coming out from said evaporator (22) and the fluid coming out from said condenser (21);
said air-conditioning system (7) being characterized in that at least said condenser (21), said evaporator (22), and said internal heat exchanger (19) are integrated so as to form a one piece assembly (16) designed to be housed in said engine compartment (2).

Abstract
An air-conditioning system is described which comprises at least one heat exchanger for exchanging heat between external air and a corresponding intermediate fluid, at least one heat exchanger for exchanging heat between air within the passenger compartment and a corresponding intermediate fluid, and an enbloc assembly wherein at least a condenser for a coolant, an evaporator of the coolant, and an internal heat exchanger are integrated. The internal heat exchanger is designed to enable heat exchange between the coolant coming out from the evaporator and coolant coming out from the condenser. The enbloc assembly is housed inside the engine compartment, along with a compressor for the coolant.
