Problems solved by technology

However, the output of the evaporator mode is affected when the temperature of the air flow through the front face exchanger drops below 0°C and the air flow contains a certain level of humidity
This condition leads to icing of the front face exchanger, which affects heat exchange

Embodiment Construction

[0053]In the present invention shown in detail and described below Figures 2 to 7 In , fluid circulation is represented by solid lines and no fluid circulation is represented by dashed lines, as has been conventional.

[0054] As shown, an air conditioner 1 according to the present invention includes a refrigerant circuit 2 and a coolant circuit 3 .

[0055] The refrigerant circuit 2 is a closed circuit in which a refrigerant fluid circulates. The refrigerant fluid may be a subcritical refrigerant fluid, such as a composition known by the designation R1234yf or R134A. The refrigerant fluid may also be a supercritical refrigerant fluid, such as carbon dioxide known by the designation R744A.

[0056] The refrigerant fluid is circulated through a compressor 4 whose function is to increase the pressure and temperature of the refrigerant fluid. Compressor 4 is advantageously electric, particularly adapted to operate at a voltage between 200 and 500 volts. "Electric" is underst...

Abstract

The invention relates to an air conditioning device 1 comprising a refrigerant circuit 2 and a coolant circuit 3, - the refrigerant circuit 2 comprising at least a compressor 4, an internal heat exchanger 5, an external heat exchanger 6 and an evaporator 7, - the coolant circuit 3 comprising at least a first heat exchanger associated with a component 8, a second heat exchanger associated with a component 9 and a radiator 11, - a fluid / fluid heat exchanger 12 installed in the refrigerant circuit 2 and in the coolant circuit 3, the coolant circuit 3 comprising a first loop 13 and a second loop 14 which are interconnected by an interconnection device 15, characterized in that the first loop 13 comprises the fluid / fluid heat exchanger 12, the first heat exchanger associated with a component 8 and a means 16 for heating the coolant which means is interposed between the interconnection device 15 and the fluid / fluid heat exchanger 12, the second loop 14 comprising the second heat exchanger associated with a component 9 and the radiator 11.

Description

technical field [0001] The technical field of the invention is that of motor vehicles, in particular electric vehicles. More specifically, the invention relates to an air-conditioning device that ensures heating and cooling of the passenger compartment and the electric drive train of such vehicles. Background technique [0002] Currently, automobile manufacturers develop vehicles that work on the basis of new energy sources, which replace or complement vehicles with internal combustion engines. In particular, vehicles that provide propulsion based on electric power are proposed. Such a scheme presents an interesting alternative. However, different components associated with the electric drive train must be installed, such as a battery for storing electrical energy, an electric motor for ensuring the vehicle's propulsion, and an inverter for transmitting electric signals to the electric motor. [0003] The service life and performance levels of these components, especially...
