Now a day’s usage of automobile is developed to next extent though for short and long travel distance people are preferring automobiles that to four wheelers for their comfortable journey. In order to increase the comfort level of the passenger several systems like HVAC and many other systems are developed. In order make the journey more comfort passengers need to feel good during their seating portion so in our project we had planned to obtain the cooling system for the seating arrangement.
The fan arrangement is placed below the seating and resting portion of the seat and this is powered due to the activation of the ignition key. This system is properly controlled by means of microcontroller board in order to identify the on and off state of the system.
Although thermal expansion systems worked well on low-output engines, they couldn’t cool the high-speed engines introduced in the 1920s. These made engine-driven water pumps come into common usage early in the century. Thermostats operated by wax pellets or thermostatic springs also came into common usage during the 1920s to warm the engine faster and maintain even operating temperatures.
Further refinements included a cooling system bypass system designed to circulate coolant throughout the engine while it’s warming up. Some engines also use double-seat thermostats to close the bypass when the thermostat opens, and pressurized cooling systems were introduced to prevent coolant boil-over on hot days.
The first cooling fans were conveniently mounted on the engine-driven water pumps and still are today. During the 1960s, cooling fans were mounted on temperature-sensitive fan clutch devices to reduce power loss at the engine crankshaft. The 1960s and ’70s also saw horizontal-core radiators being introduced to accommodate reduced body height and increased cooling system demand. Many horizontal-core radiators also require remote coolant reservoirs to help evacuate air from the cooling system.
Electric cooling fans began to appear on many imports because they could be activated only when engine temperatures reached a critical point. This eliminated the power loss associated with mechanical fans, and also increased fuel economy and reduced cold-engine exhaust emissions by reducing engine warm-up time. To further reduce emissions, thermostat opening temperatures were increased to about 195° F.
The system consists of pairs of fans placed behind the seating and resting portion of the seat, the working of fans is activated by means of push button which is placed at the seating portion of the seat. It gets powered from the microcontroller arrangement which senses the activation of the ignition key.
When the ignition key is turned on then the microcontroller receives the signal for activating the fan, when the passenger seats on the seat then the push button gets activated and tend to activate the fan which is powered by means of battery. Due to the activation of fan seat remains cool and so the body temperature of the passenger maintains constant so it helps them to make a comfortable journey.
• Simple system
• Cost and energy efficient
• Maintenance is easy
• components used are easily available
• This system can be applied for normal as well as luxurious car
