Installation for thermal conditioning of a passenger compartment and / or at least one member of a motor vehicle
The present invention relates to a thermal conditioning installation for a passenger compartment and / or at least one member of a motor vehicle.
Known installations are capable of heating or cooling (air conditioning) the passenger compartment of a vehicle, as well as heating or cooling a member of the vehicle, such as the battery.
Electric vehicles use electric motors coupled to inverters, these elements tend to heat up during their use. In addition, a hybrid vehicle also includes a heat engine capable of ensuring the advancement of the vehicle, alternately or in addition to the electric motors.
In order to ensure optimal functioning of these organs, it is useful to condition them thermally, that is to say to maintain their temperature within a determined temperature range. For example, the optimal temperature range of a battery is between 0 and 55 ° C, preferably between 25 and 35 ° C.
At the same time, the installation must also be able to effectively condition the passenger compartment, especially when the outside air is relatively cold or hot. There is a need to be able to condition the passenger compartment quickly, in particular when the passenger compartment is at temperatures very far from the comfort temperature desired by the user.
The object of the invention is in particular to provide a simple, effective and economical solution to these problems.
To this end, it offers a thermal conditioning installation for a passenger compartment and / or at least one member of a motor vehicle, comprising:
- a first circulation circuit for a heat transfer fluid,
- A second refrigerant circulation circuit, capable of forming a heat pump type circuit, characterized in that the heat transfer fluid circuit includes heating and / or cooling means intended to heat and / or cool the at least one member of a motor vehicle, such as for example a battery, an electric motor or a heat engine, means for storing calories and / or frigories, a first heat exchanger forming an evaporator and able to exchange heat with the refrigerant circuit, and means for circulating the heat transfer fluid, capable of drawing frigories and / or calories from the storage means or the first exchanger, so as to transfer them to the means of heating and / or cooling.
The storage means make it possible to very quickly deliver calories or frigories to the air opening into the passenger compartment of the vehicle, so as to quickly reduce the temperature thereof to a set temperature. Said calories or frigories can also be used to condition the organ of the vehicle.
The first heat exchanger makes it possible to produce an interface between the refrigerant circuit and the heat transfer fluid circuit, so as to be able to use the heat pump to cool the organ of the vehicle to be conditioned, or even to recharge a calorifier , if needed.
The heat pump type circuit may include at least one compressor, at least one heat exchanger forming a condenser, at least one pressure reducer and at least one heat exchanger forming an evaporator.
The heat pump type circuit can also include an accumulator, also called an expansion tank, upstream of the compressor.
The heat transfer fluid circuit may include a second heat exchanger capable of heating or cooling air intended to open into the passenger compartment of the vehicle, the means for circulating the heat transfer fluid being able to draw frigories and / or calories from storage means or the first exchanger, so as to transfer them to the second exchanger.
The second exchanger is for example located in a duct of a heating, ventilation and / or air conditioning installation, also called H.V.A.C. (Heating, Ventilation and Air-Conditioning, in English), said duct being intended to open into the passenger compartment of the vehicle.
The storage means can be a removable storage device, which can either be a calorie storage device or a cold storage device, depending on requirements.
As a variant, the storage means comprise at least one calorie store and at least one refrigeration store.
The heat transfer fluid circuit may include a third heat exchanger capable of exchanging heat with outside air, the means for circulating the heat transfer fluid being able to transfer frigories from the third heat exchanger to at least one components of the vehicle, for example to the heat engine or the electric motor, and / or the battery.
In this way, the third heat exchanger makes it possible, at least in part, to cool at least one of the components of the vehicle.
The third exchanger is for example located on the front of the vehicle.
The third heat exchanger makes it possible to compensate for a possible lack of cooling power supplied by the first exchanger, depending on the conditions external and / or internal to the vehicle.
The refrigerant circuit may include a fourth heat exchanger capable of forming a condenser and capable of exchanging heat with air intended to open into the passenger compartment of the vehicle.
The fourth exchanger is for example located in the duct of a heating, ventilation and / or air conditioning (H.V.A.C.) installation.
The refrigerant circuit may include a fifth heat exchanger capable of forming an evaporator and / or a condenser and capable of exchanging heat with air outside the vehicle.
The fifth exchanger is for example located on the front face of the vehicle.
The refrigerant circuit may include a sixth heat exchanger capable of forming an evaporator and capable of exchanging heat with air intended to open into the passenger compartment of the vehicle.
The sixth exchanger is for example located in a duct of an installation of the H.V.A.C. type.
The heat transfer fluid circuit may include first heating means, such as for example a first electrical resistance, capable of heating the heat transfer fluid upstream of one of the vehicle components.
These first heating means are for example located upstream of the battery, so as to operate in addition to the corresponding cooling and / or heating means.
The heat transfer fluid circuit may include second heating means, such as for example a second electrical resistance, capable of heating the heat transfer fluid intended to circulate in the calorifier.
The second heating means can thus function in addition to the elements already present, to ensure or facilitate the storage of calories in the calorie store.
The installation may include third heating means, such as for example a third electrical resistance, capable of heating the air intended to open into the passenger compartment of the vehicle.
The third heating means can thus operate in addition to the second heat exchanger and / or the fourth heat exchanger, for example.
The heat transfer fluid circuit may include bypass means capable of deriving all or part of the heat transfer fluid outside of said heating and / or cooling means.
The installation may include means for circulating the coolant and means for circulating the refrigerant designed to operate in at least one of the following modes:
