Description:FIELD OF INVENTION
[0001] Embodiments of the present disclosure relate to the field of a vehicle air-conditioning system, and more particularly, a system and a method for air-conditioning of a vehicle with dual line control.
BACKGROUND
[0002] A conventional vehicle air-conditioning (AC) system typically utilizes a single line control method, where a compressor operation is controlled based on a single AC request signal from a front AC control panel. Although this method has been widely used, this method has several disadvantages that limits its effectiveness and user convenience.
[0003] One of the main drawbacks is limited control over the air-conditioning system. Using a single AC request signal, the system fails to consider the specific requirements of passengers in a rear area of a vehicle. This results in a lack of customized cooling options for passengers in the rear area which can lead to dissatisfaction and discomfort during travel.
[0004] Further, compressor operation and AC control in vehicles with single AC signal restricts the passengers in the rear area to control over the compressor. While passengers can adjust the rear side AC settings, they are unable to independently control the compressor from the rear end. This limitation prevents them from effectively managing the cooling performance in rear area, as the compressor operation remains solely dependent on the front AC control panel.
[0005] Hence, there is a need for an improved system and method for air-conditioning of a vehicle with dual line control which addresses the aforementioned issue(s).
OBJECTIVE OF THE INVENTION
[0006] An objective of the invention is to provide air-conditioning of a vehicle with dual line control.
[0007] Another objective of the invention is to provide control over a compressor from the rear-end area of the vehicle.

[0021] FIG. 1 is a block diagram representation of a system for air-conditioning of a vehicle with dual line control in accordance with an embodiment of the present disclosure. The system (100) includes a first control unit (126) positioned at a front end of the vehicle. Examples of the vehicle includes, but is not limited to, car, van, sport utility vehicle (SUV) and the like. In one embodiment the vehicle has a large capacity to accommodate a 24-seater. The first control unit (126) includes a control panel (128) operatively coupled to a vehicle supply (120). The vehicle supply (120) refers to an electrical power source provided by a battery of the vehicle to supply necessary power for the control panel (128) and other components of the system (100) to operate effectively. The power from the vehicle supply (120) is first directed to a blower motor (122, 142). The blower motor (122, 142) is responsible for generating airflow by spinning fan blades of the blower motor (122, 142). The output of the blower motor (122) is then connected to a resistor (124, 144). The resistor (124, 144) acts as a control device, regulating the voltage or current supplied to the blower motor (122, 142). Further, the resistor (124, 144) allows for different fan speed settings by adjusting the resistance. The connection from the resistor (124) leads to the control panel (128). Likewise, the connection from the resistor (144) leads to the second control unit (146). The control panel (128) is configured to receive a first air-conditioning request from a user seated at the front end of the vehicle through a user interface. The first air-conditioning request is to customize a plurality of operations pertaining to the air-conditioning of the vehicle. Examples of the plurality of operations include, but is not limited to, adjusting the temperature to their desired level, selecting the appropriate fan speed, choosing between different modes such as cooling or ventilation, and other customizable options.
[0022] In an embodiment, the user interface may be a touchscreen display on the control panel (128), allowing the user to interact with the system (100) by tapping or swiping on the screen. The user interface may include buttons, sliders, and icons to adjust various settings to customize the plurality of operations. Through the user interface on the control panel (128), the user may easily navigate and select their preferred air-conditioning settings, thereby customizing the plurality of operations.
[0023] The control panel (128) includes a blower motor switch (130). The blower motor switch (130) is configured to allow the user to customize the plurality of operations related to at least one of fan speed and intensity of the airflow in accordance with the preference of the user. The control panel (128) includes an air-conditioning button (132). The air-conditioning button (132) is configured to enable the system (100) to exhibit an operative state and an inoperative state respectively. When the user turns the air-conditioning button (132) ‘ON’, the user has the option to activate the air-conditioning button (132) on the control panel (128). This action initiates an air-conditioning process and triggers the first air-conditioning request.
[0024] The control panel (128) in a vehicle's air-conditioning is typically connected to the ground (134) for electrical safety, maintains proper circuit operation and protects the system (100) and its components from potential electrical issues.
[0025] Further, the first control unit (126) includes a first thermo-amplifier (136) operatively coupled to the control panel (128). The first thermo-amplifier (136) is an integrated circuit (IC) specifically designed for air-conditioning control systems to accurately control and regulate the temperature inside the vehicle. The first thermo-amplifier (136) works by analyzing temperature inputs and generating corresponding signals to adjust the plurality of operations. The first thermo-amplifier (136) generates a first air-conditioning signal based on analyzing the first air-conditioning request and temperature from a first sensor (138). The first sensor (138) is configured to monitor the temperature input by monitoring the temperature in the front end of the vehicle.
[0026] In one embodiment, the first sensor (138) is an evaporator temperature sensor. The first sensor (138) is typically positioned near a front evaporator coil that is responsible for cooling the air before it enters a cabin of the vehicle. The evaporator temperature sensor measures the temperature of the refrigerant flowing through the evaporator coil. It can provide precise temperature readings to the first thermo-amplifier (136), allowing the system (100) to accurately assess the cooling requirements.
[0027] Furthermore, the first control unit (126) includes a first logic relay (140) to generate an output air-conditioning signal by employing logical operations on the first air-conditioning signal. By employing logical operations, the first logic relay (140) ensures that the output air-conditioning signal accurately reflects the desired air-conditioning settings and temperature inside the cabin of the vehicle.
[0028] The system (100) includes a second control unit (146) positioned at a rear end of the vehicle. The second control unit (146) includes a second thermo-amplifier (152) operatively coupled to the second control unit (146). The second thermo-amplifier (152) is configured to generate a second air-conditioning signal based on analyzing a second air-conditioning request received through a blower switch (148) and temperature from a second sensor (154). The second sensor (154) is configured to monitor the temperature on the rear end of the vehicle. Further, the second control unit (146) includes a second logic relay (156) operatively coupled to the second thermo-amplifier (152). The second logic relay (156) is configured to generate the output air-conditioning signal by employing logical operations on the second air-conditioning signal. The blower switch (148) allows the user to operate the blower switch (148) to the 'ON' or 'OFF' state. The blower switch (148) triggers the air conditioning request in the rear end when the blower switch (148) is in the 'ON' state.
[0029] The blower switch (148) in the vehicle's air-conditioning system (100) is connected to the ground (150) for electrical safety, maintains proper circuit operation and protects the system (100) and its components from potential electrical issues.
[0030] The system (100) includes a control unit (158) operatively coupled to the first logic relay (140) and the second logic relay (156). The control unit (158) is configured to receive the output air-conditioning signals from the first logic relay (140) and the second logic relay (156) via a pressure switch (160). It must be noted that the only one output air-conditioning signal will pass through the pressure switch (160). Further, only when both the first logic relay (140) and the second logic relay (156) passes a signal indicating that air conditioning is not required, the compressor relay (164) will turn to the ‘OFF’ state (until then the compressor relay (164) will be in the ‘ON’ state). The pressure switch (160) is commonly used to monitor the pressure of a refrigerant within the system (100). It is typically installed in the refrigerant lines or components such as a compressor or condenser. The pressure switch (160) is designed to detect and respond to variations in pressure.
[0031] Further, the control unit (158) is configured to control a compressor relay (164) based on the output air-conditioning signals. The compressor relay (164) is turned to ‘ON’ state in response to the output air-conditioning signal indicating the air-conditioning request. The compressor relay (164) is turned to 'OFF' state in in response to the output air-conditioning signal indicating no air-conditioning request, thereby causing a dual control for air-conditioning to the vehicle.
[0032] When the first logic relay (140) and second logic relay (156) are ‘ON’, the system (100) is activated and the compressor relay (164) turns ON, resulting in the vehicle's air-conditioning operating to provide cooling and the desired air-conditioning mode. If the first logic relay (140) is OFF and the second logic relay (156) is ON, the system (100) remains activated, and the compressor relay (164) stays turned ON, indicating that the user in the rear area have requested air-conditioning while the front area may not require cooling. Similarly, if the first logic relay (140) is ON and the second logic relay (156) is OFF, the system (100) remains activated with the compressor relay (164) turned ON, indicating that the front area requires air-conditioning while the user in the rear area may not need cooling. However, when the first logic relay (140) and second logic relay (156) are OFF, the system is deactivated, and the compressor relay (164) is turned OFF, indicating that the user in the front area and the rear area does not require cooling.
[0033] In an example, let’s consider a car installed with the system (100) for air-conditioning with dual line control. The car has two users: User 'X' who is sitting in the front area of the car, and User 'Y' who is sitting in the rear area of the car. Each user has their own specific preference for cooling and air-conditioning mode. The user ‘X’ selects his/her preference by adjusting the air-conditioning setting through the user interface of the first control unit (126) available in the front area which trigger the first air-conditioning request. The user ‘Y’ selects his/her preference by adjusting the blower switch (148) on the second control unit (146) in the rear area which in turn triggers the second air-conditioning request. The first thermo-amplifier (136) of the first control unit (126) continuously monitors the first air-conditioning request along with the temperature reading from the first sensor (138), which is typically located in the front area. Based on this information, the first thermo-amplifier (136) generates the first air-conditioning signal. Similarly, the second thermo-amplifier (152) of the second control unit (146) analyses the second air-conditioning request received and considers the temperature reading from a second sensor (154), which is usually placed in the rear area of the car. This analysis results in the second air-conditioning signal. The first and second air-conditioning signals are then processed by the first logic relay (140) and second logic relay (156) respectively and logical operations are performed on the signals to obtain an output air-conditioning signal. Further, the output air-conditioning signal from the first logic relay (140) and second logic relay (156) is sent to the control unit (158). The control unit (158) receives the signal and determines the action for the system (100). Based on the received signal, the control unit (158) activates or deactivates the compressor relay (164), which is responsible for turning the air-conditioning system ON or OFF. If both the front and rear air-conditioning signals indicate a request for cooling, the control unit (158) turns ON the compressor relay (164), allowing the system to cool the cabin of the car. If any one of the signals indicates the air-conditioning request, the control unit turns ON the compressor relay (164). If there is no air-conditioning request, then the compressor relay (164) is turned OFF, thereby user ‘X’ and user ‘Y’ get their desired cooling condition.

FIG. 2(b) illustrates continued steps of the method of FIG. 2(a) in accordance with an embodiment of the present disclosure. The method (300) includes receiving, by a control panel of a first control unit, a first air-conditioning request from a user seated at the front end of the vehicle through a user interface. The first air-conditioning request is to customize a plurality of operations pertaining to the air-conditioning of the vehicle in step 310. The user interface, which may include buttons, sliders, and icons, allows the user to customize a variety of air-conditioning operations specific to the vehicle.
[0035] The method (300) includes generating, by a first thermo-amplifier of the first control unit, a first air-conditioning signal based on analyzing the first air-conditioning request and temperature from a first sensor. The first sensor is configured to monitor temperature on the front end of the vehicle in step 320.
[0036] The method (300) includes generating, by a first logic relay of the first control unit, an output air-conditioning signal by employing logical operations on the first air-conditioning signal in step 330. The first logic relay ensures that the output air-conditioning signal accurately represents the desired air-conditioning settings and conditions inside the vehicle's cabin.
[0037] The method (300) includes generating, by a second thermo-amplifier of a second control unit, a second air-conditioning signal based on analyzing a second air-conditioning request received through a blower switch and temperature from a second sensor. The second sensor is configured to monitor the temperature on the rear end of the vehicle in step 340.
[0038] The method (300) includes generating, by a second logic relay of the second control unit, the output air-conditioning signal by employing logical operations on the second air-conditioning signal in step 350. The second logic relay ensures that the output air-conditioning signal accurately reflects the desired air-conditioning settings and conditions specific to the rear end of the vehicle.
[0039] The method (300) includes receiving, by a control unit, the output air-conditioning signals from the first logic relay and the second logic relay via a pressure switch in step 360.
[0040] The method (300) includes controlling, by the control unit, a compressor relay based on the output air-conditioning signals. The compressor relay is turned to ‘ON’ state in response to the output air-conditioning signal indicating the air-conditioning request. The compressor relay is turned to 'OFF' state in in response to the output air-conditioning signal indicating no air-conditioning request, thereby causing a dual control for air-conditioning to the vehicle in step 370.
