Vehicle Environmental Conditioning System and Method
An air conditioning system for a vehicle includes a climate control system for selectively heating and cooling ambient air in a passenger compartment of the vehicle. One or more fans cooperate with the climate control system and are configured to draw air from the passenger compartment to expel air to the exterior of the vehicle. One or more devices are provided in proximity to the passenger compartment to detect a variety of conditions of the air in the passenger compartment. The one or more devices selectively signal a controller to activate and deactivate the one or more fans prior to an occupant entering the vehicle. The controller may activate the one or more fans to draw air from the passenger compartment based on detection of predetermined conditions in response to input from the one or more devices.
1 . An environmental conditioning system for a vehicle comprising:
a climate control system for selectively heating and cooling ambient air in a passenger compartment of the vehicle;
one or more fans cooperating with the climate control system configured to draw air from the passenger compartment to expel air to the exterior of the vehicle;
a controller operatively connected to and communication with the climate control system and the one or more fans; and
one or more devices provided in proximity to the passenger compartment for detecting the condition of the air and selectively signaling the controller to activate and deactivate the one or more fans prior to an occupant entering the vehicle,
wherein the controller activates the one or more fans to draw air from the passenger compartment based on detection of predetermined conditions in response to input from the one or more devices.
2 . The system of claim 1 wherein the one or more fans include a single bidirectional fan cooperating with the climate control system to provide air to and draw air from the passenger compartment.
3 . The system of claim 1 wherein the one or more fans include multiple unidirectional fans disposed adjacent vents in the passenger compartment to draw air from the passenger compartment.
4 . The system of claim 1 wherein the one or more devices comprise one or more temperature sensors configured to sense the temperature of ambient air in the passenger compartment and transmit a signal to the controller.
5 . The system of claim 1 wherein the one or more devices comprise a timer configured to transmit a signal to the controller to activate the one or more fans at a predetermined time.
6 . The system of claim 1 wherein the one or more devices comprise a manual actuator configured to transmit a signal to the controller to activate the one or more fans.
7 . The system of claim 1 wherein the one or more devices include a remote keyless entry system configured to transmit a signal to the controller to activate the one or more fans.
8 . The system of claim 1 wherein the controller automatically activates the one or more fans when the one or more devices provide input to the controller indicative of a condition exceeding a predetermined level.
9 . The system of claim 1 wherein the one or more fans are components of the climate control system.
10 . The system of claim 1 wherein the one or more fans are independent of the climate control system.
11 . The system of claim 1 wherein the controller selectively operates a retractable window cover in response to input from the one or more devices.
12 . An environmental conditioning system incorporating a climate control system for selectively heating and cooling ambient air in a passenger compartment of a vehicle, the system comprising:
one or more fans cooperating with the climate control system configured to draw air from the passenger compartment to expel air to the exterior of the vehicle;
a controller operatively connected to and communication with the one or more fans and a remote keyless entry system of the vehicle; and
one or more devices provided in proximity to the passenger compartment for detecting the condition of the air and selectively signaling the controller to activate and deactivate the one or more fans prior to an occupant entering the vehicle,
wherein the controller activates the one or more fans to draw air from the passenger compartment based on detection of predetermined conditions in response to input from the one or more devices and an activation signal from the remote keyless entry system.
13 . The system of claim 12 wherein the one or more fans include a single bidirectional fan cooperating with the climate control system to provide air to and draw air from the passenger compartment.
14 . The system of claim 12 wherein the one or more fans include multiple unidirectional fans disposed adjacent vents in the passenger compartment to draw air from the passenger compartment.
15 . The system of claim 1 wherein the one or more devices comprise one or more temperature sensors configured to sense the temperature of ambient air in the passenger compartment and transmit a signal to the controller.
16 . The system of claim 1 wherein the one or more devices comprise a timer configured to transmit a signal to the controller to activate the one or more fans at a predetermined time.
17 . The system of claim 1 wherein the one or more devices comprise a manual actuator configured to transmit a signal to the controller to activate the one or more fans.
18 . A method of conditioning the environment in the passenger compartment of a vehicle, the method comprising:
providing a controller for monitoring the environmental conditions of the passenger compartment;
sending a signal to the controller from the one or more devices;
analyzing the signal input from the one or more devices; and
selectively operating one or more fans with the controller based on the analysis of input from the one or more devices to remove air from the passenger compartment.
19 . The method of claim 18 further comprising the step of sensing the environmental conditions of the passenger compartment with one or more devices and transmitting signals to the controller for analysis.
20 . The method of claim 18 further comprising the step of selectively operating at least one of the vehicle engine, climate control system, windows, doors and air purifier based on the analysis of input from the one or more devices to remove air from the passenger compartment.
