Description

P34958NLOO/NBL Vehicle cabin climate control system The invention pertains to a vehicle cabin climate control system.
In particular in electric vehicles, the vehicle cabin climate control system consumes a considerable amount of energy.
Several solutions have been proposed to reduce the amount of energy needed for vehicle cabin climate control. For example, DE102015115196 discloses a system which comprises a peripheral heat exchanger. In this peripheral heat exchanger, air that is introduced into the vehicle cabin climate control system from outside the vehicle flows through one side of the peripheral heat exchanger and air that is expelled from the vehicle cabin flows through the other side of the peripheral heat exchanger. This way, heat exchange takes place between the incoming air and the outgoing air, therewith pre-heating or pre- cooling the incoming air is obtained, depending on whether the temperature in the vehicle cabin is above or below the temperature of the outside air. This way, the heating or cooling that has to be done by the vehicle cabin climate control system is reduced, and therewith, the energy consumption is reduced.
However, the effect of this system on the total energy consumption of the vehicle cabin climate control system is limited.
The invention aims to provide an energy efficient vehicle cabin climate control system.
This object is obtained by a vehicle cabin climate control system which comprises: - an air inlet system comprising an air inlet, which air inlet system is adapted to allow outside air to enter the vehicle climate cabin control system and to generate an inlet air flow into the vehicle cabin climate control system, which inlet air flow is generated from outside air entering the vehicle cabin climate control system via the air inlet, - an air treatment device, comprising: - an air cooler comprising an air cooler inlet for receiving an air flow, which air cooler is adapted to generate a cooled air flow from the air flow that is received through the air cooler inlet, the air cooler being arranged downstream of the air inlet, - an air heater comprising an air heater inlet for receiving an air flow, which air heater is adapted to generate a heated air flow from the air flow that is received through the air heater inlet, the air heater being arranged downstream of the air cooler,

- a primary cabin air inlet, which is arranged to receive an air flow and to introduce at least a part of that airflow into a vehicle cabin, which vehicle cabin climate control system further comprises: - a first air treatment entry point, which is arranged upstream of the air cooler, - a second air treatment entry point, which is arranged between the air cooler and the air heater, - an entry point valve system which is arranged downstream of the air inlet and upstream of the first air treatment entry point and upstream of the second air treatment entry point, which entry point valve system has a first operational mode and a second operational mode which is different from the first operational mode, wherein in the first operational mode the entry point valve system is set to direct at least a part of the inlet air flow to the first air treatment entry point, and wherein in the second operational mode the entry point valve system is set to direct at least a part of the inlet air flow to the second air treatment entry point.
The vehicle cabin climate control system according to the invention comprises an air inlet system. The air inlet system comprises an air inlet.
The air inlet system is adapted to allow outside air to enter the vehicle climate cabin control system and to generate an inlet air flow into the vehicle cabin climate control system.
The inlet air flow is generated from outside air entering the vehicle cabin climate control system via the air inlet.
Optionally, the air inlet system further comprises a flow device, to actively generate the air flow and/or to provide a required flow rate for the inlet air flow. The flow device is or comprises for example a fan.
The vehicle cabin climate control system according to the invention comprises an air treatment device which comprises an air cooler and an air heater. The air heater is arranged downstream of the air cooler, downstream being related to the direction of the air flow through the air treatment device. So, the air flows through the air cooler before at least a part of the air flows through the air heater.
The air cooler of the air treatment device comprises an air cooler inlet for receiving an air flow. This air flow for example is comprised of at least a part of the inlet air flow, the entire inlet air flow, a combination of a part of the inlet air flow with recirculated air from the vehicle cabin or the entire inlet air flow in combination with recirculated air from the vehicle cabin.
The air cooler is arranged downstream of the air inlet, downstream being related to the direction of the air flow through the vehicle cabin climate control system.
-3- The air cooler is adapted to generate a cooled air flow from the air flow that is received through the air cooler inlet. The air cooler for example is or comprises an evaporator.
The air treatment device of the vehicle cabin climate control system according to the invention further comprises an air heater which is arranged downstream of the air cooler, downstream being related to the direction of the air flow through the air treatment device. So, the air flows through the air cooler before the air flows through the air heater.
The air heater of the air treatment device comprises an air heater inlet which is arranged to receive an air flow.
The air heater of the air treatment device is adapted to generate a heated air flow from the air flow that is received through the air heater inlet.
The vehicle cabin climate control system according to the invention further comprises a primary cabin air inlet, which is arranged to receive an air flow and introduce at least a part of that received airflow into the vehicle cabin.
Optionally, the air flow that is received by the primary cabin air inlet comprises at least a part of the heated air flow that is generated by the air heater of the air treatment device, an optionally all of the heated airflow that is generated by the air heater of the air treatment device. Optionally, the air flow that is received by the primary cabin air inlet comprises at least a part of the heated air flow that is generated by the air heater of the air treatment device in combination with an air flow coming from a different source, e.g. at least a part of the inlet air flow and/or recirculated air from the vehicle cabin. Optionally, the air flow that is received by the primary cabin air inlet comprises an air flow coming from a different source than the heated air flow that is generated by the air heater of the air treatment device, e.g. at least a part of the inlet air flow and/or recirculated air from the vehicle cabin.
The vehicle cabin climate control system according to the invention further comprises a first air treatment entry point, a second air treatment entry point and an entry point valve system.
The first air treatment entry point is arranged upstream of the air cooler of the air treatment device, upstream being related to the direction of the air flowing through the vehicle cabin climate control system.
The second air treatment entry point is arranged between the air cooler of the air treatment device and the air heater of the air treatment device.
The entry point valve system is arranged downstream of the air inlet and upstream of the first air treatment entry point and upstream of the second air treatment entry point. With the entry point valve system being located between the air inlet on the one hand and the first
-4- and second air treatment entry points on the other hand, the entry point valve system is arranged to control the direction of the inlet air flow to either the first air treatment entry point, or to the second air treatment entry point, and optionally to split the inlet air flow in a first flow to the first air treatment entry point and a second flow to the second air treatment entry point. The entry point valve system has a first operational mode and a second operational mode which is different from the first operational mode. In the first operational mode the entry point valve system is set to direct at least a part of the inlet air flow to the first air treatment entry point. In the second operational mode the entry point valve system is set to direct at least a part of the inlet air flow to the second air treatment entry point. Optionally, a first duct is provided between the air cooler and the air heater, and the second air treatment entry point is arranged at the first duct. In vehicle cabin climate control systems, an air cooler is often used for dehumidifying air, for example air that is withdrawn from the outside environment of the vehicle and/or air that is recirculated from the vehicle cabin. By cooling this air, the air gets dryer. In general, the colder the air gets, the less moisture it is able to contain. If the air is cooled to a temperature at or below the dew point, water vapour condensates from the air. However, this dehumidified air often has a temperature which is below the temperature at which the air should be introduced into the vehicle cabin of the vehicle in which the vehicle cabin climate control system is arranged for obtaining the desired temperature in the vehicle cabin, for example the desired cabin temperature as set by an occupant of the vehicle. Therefore, the dehumidified air often needs to be heated in order to obtain the desired vehicle cabin temperature.
However, cooling an air flow for the purpose of dehumidification consumes quite a lot of energy, and if the outside air is already sufficiently dry, cooling for dehumidification purposes is not necessary. The vehicle cabin climate control system according to the invention allows to avoid cooling of at least a part of the inlet air flow if the incoming air flow does not need to be cooled. The vehicle cabin climate control system according to the invention allows to tailor the setting of the entry point valve system to the outside air conditions, in particular to the outside air parameters of humidity, relative humidity and/or temperature, so the vehicle cabin climate control system does no more than what is necessary to obtain the desired vehicle cabin climate conditions in terms of humidity, relative humidity and/or temperature. Therewith, energy consumption of the vehicle cabin climate control system is reduced.
-5- In an embodiment of the vehicle cabin climate control system according to the invention, in the first operational mode the entry point valve system is set to direct a first portion of the inlet air flow to the first air treatment entry point and a second portion of the inlet air flow to the second air treatment entry point, and the first portion of the inlet air flow is larger than the second portion of the inlet airflow.

-8- The cabin sensor system is adapted to generate vehicle cabin parameter measurement data. Optionally, the cabin sensor system comprises a plurality of sensors, e.g. climate parameter sensors and/or other sensors, wherein different sensors of the plurality of sensors measure different parameters and/or wherein different sensors of the plurality of sensors measure parameters at different locations.
In this embodiment, the entry point valve system comprises an entry point valve system controller which is adapted to control the setting of the operational mode of the entry point valve system at least partly based on the climate parameter measurement data as generated by the cabin sensor system.
In an embodiment of the vehicle cabin climate control system according to the invention, the vehicle climate control system further comprises a primary cabin air outlet and a recirculation line. The recirculation line extends between the primary cabin air outlet and the air treatment device. The recirculation line is arranged to supply a recirculation air flow from the vehicle cabin to the air cooler inlet. The first air treatment entry point is arranged at the recirculation line upstream of the air cooler.
In this embodiment, air is extracted from the vehicle cabin. The extracted air is at least partly recirculated back into the vehicle cabin via a recirculation line. The recirculated air may need to be dehumidified because if vehicle occupants are present in the vehicle cabin, the humidity of the air in the vehicle cabin increases. In addition to the extraction of air from the vehicle cabin for the purpose of recirculation, air will be extracted from the cabin and dumped outside the vehicle cabin in order to keep the carbon dioxide level in the vehicle cabin at an acceptable level. For example, an air exhaust line may be present which is connected to the recirculation line, and the portion of air that is extracted from the vehicle cabin via the recirculation line flows into the air exhaust line and from there to outside the vehicle. Alternatively or in addition, a second primary cabin air outlet may be provided which obtains air directly from the vehicle cabin and an air exhaust line is connected to the second primary cabin air outlet for direct discharge of air from the vehicle cabin.

If the entry point valve system is in an operational mode in which at least a portion of the inlet air flow is directed to the first air treatment entry point, this portion of the inlet air flow is mixed with recirculated air from the vehicle cabin.
In case the entry point valve system is in an operational mode in which none of the inlet air flow is directed to the first air treatment entry point, the air cooler of the air treatment device only dehumidifies the recirculated air (by cooling).

This is advantageous if the desired vehicle temperature setting does not require that all cooled air is heated in order to obtain the desired vehicle cabin temperature.
In an embodiment of the vehicle cabin climate control system according to the invention, the vehicle cabin climate control system further comprises a peripheral heat exchanger. The peripheral heat exchanger has a first side passage and a second side passage, and the first side passage and the second side passage are arranged to allow heat transfer between an air flow within the first side passage and an air flow within the second side passage.

-10- side passage of the peripheral heat exchanger and the vehicle cabin climate control system further comprises a cabin air discharge passage which is adapted to discharge air from the vehicle cabin. The cabin air discharge passage is in fluid communication with the upstream end of the second side passage of the peripheral heat exchanger. The cabin air discharge passage and the air discharge passage both may form part of an air exhaust line.
Optionally, in this first variant, the vehicle cabin climate control system further comprises a cold air discharge which comprises a cold air discharge inlet which is arranged to receive at least a part of the cooled air flow that is generated by the air cooler of the air treatment device and a cold air discharge outlet which is in fluid communication with the upstream end of the second side passage of the peripheral heat exchanger.
