Preface

The prioritization placed on comfort and convenience reflects in modern day car buying practices. While the air conditioning spells out the blast of cool air feels heavenly during hot summer drives, a seat ventilation system takes it a notch higher. It serves as a game-changing feature for both passengers and drivers alike.
Unlike before, there is now more focus onto the comfort aspects of modern cars which is what we will be diving deeper into. A seat ventilation system shouldn’t be considered an unnecessary add-on. This article aims to explain the reasons for their growing preference among buyers, how these systems function, and the advantages they confer.

What is a seat ventilation system?

A seat ventilation system is exactly what it sounds like – a system designed to keep your car seats cool and comfortable, even in the hottest weather. But how does it differ from your car’s regular air conditioning? Let’s break it down.
A seat ventilation system is a specialized feature in modern cars designed to improve comfort by circulating air through the seat’s upholstery. Unlike traditional air conditioning, which cools the air in the cabin, a seat ventilation system cools the seat directly, providing targeted relief for the driver and passengers.

Comparing Seat Ventilation to Traditional Air Conditioning

When considering methods of keeping cool in a car, traditional air conditioning is a common thought. Traditional air conditioning works by chilling the entire cabin, moving cooled air around through vents to drop the overall temperature, which usually has less of a disadvantage than advantages. With this, every passenger is ensured a cold environment, which is ideal for long trips with family or friends. But, the system has its drawbacks too. It can take several minutes to cool a sun-baked car interior, and it consumes a significant amount of energy, resulting in less fuel efficiency.
To this end, we have a ventilation system built into the seats, which is an evolution on an air conditioning system. That unit’s cooling should be the most intensive in the area of the seat. Unlike ordinary AC, which lowers ambient temperature, seat ventilation relies on the infusion of air into the seat itself. It is possible to create a micro-climate inside the vehicle which is customized to individual passengers. This offers some very specific advantages. Furthermore, since the scope of the cooling area of seat ventilation unit is much larger, less energy is used relative to what is used by traditional AC systems. This could serve to minimize the overall usage of air conditioning, potentially saving fuel and reducing the environmental footprint of the car.
Feature Seat Ventilation Traditional Air Conditioning
Cooling Area Directly cools the seat surface and body for targeted relief Cools the entire cabin, impacting all areas of the car
Energy Consumption More energy-efficient, cooling a localized area Consumes more energy as it cools the entire cabin
Time to Cool Down Provides quicker relief to individual passengers Takes longer to cool down the cabin, especially if the car has been sun-heated
Comfort Personalized comfort for each passenger with adjustable fan speeds Uniform cooling but less customizable for individual comfort
Environmental Impact Lower environmental impact due to reduced energy use Higher environmental impact due to greater energy consumption
Supplementary Feature Works best in combination with traditional AC for overall comfort Acts as the primary cooling system in the vehicle
However, a ventilated seat does not serve as a replacement for traditional AC, so the caveat needs to be made upfront. Instead, it operates best as an assistive feature, enabling a target temperature for the driver and passengers to be achieved quickly, while the conventional AC cools the cabin. The two devices combined broaden the range of possible cooling solutions to the driver/passengernand can greatly improve comfort when driving during hot summer days.

How Seat Ventilation Systems Improve Comfort

Now that we know what a seat ventilation system is, let’s look at how it actually works to keep you cool and comfortable.

Components of a Seat Ventilation System

A standard seat ventilation system has a number of important components:
  • Fans or blowers: These serve as the system’s ‘workhorses’, propelling air through the seat.
  • Perforated leather or fabric: This facilitates the movement of air through the seat’s surface.
  • Temperature sensors: These check the seat temperature to moderate comfort on the seat.
  • Controller: This is the system’s ‘brain’ since it varies the fan’s power according to the data received from the sensors.

The Process: From Air Circulation to Cooling

Let us see how everything works together:
  • The system starts by collecting air from the cabin through tiny intake vents.
  • Then, this air is forced through the channels that pass through the seat cushion and the backrest.
  • As the air exits from the perfurated surface of the seat, it comes in contact with the body and exits the seat. As a result, a cooling effect is generated.
Though this is a basic process, the end result greatly increases one’s level of comfort. A chair with such ventilation systems reportedly has high comfort when sitting. A study by the National Renewal Energy Laboratory indicates that ventilated seats can allow a sun-heated seat surface temperature to decrease by 15°C (27°F) in just 1 minute of use.

Types of Seat Ventilation Systems

All seat ventilation systems are different and unique. Let’s analyze the two most common types of systems intently alongside their functionalities and their possible applications.

Fan-based systems

The use of small fans or blowers that move air through a seat is referred to as fan-based systems. This is the most common type of seat ventilation. The systems normally make use of axial fans or centrifugal blowers. Centrifugal blowers expel air at right angles to the intake while axial fans move air parallel to the shaft. Due to their compact nature, axial fans are most commonly used for their small size. On the other hand, centrifugal blowers are preferred for their functionality in moving air against high pressure found in luxury vehicles.
Normally, the fans draw air from the cabin, and blow it through channels in the seat foam. The fans are usually found in the seat cushion or the backrest. This air exits the seat covering through tiny perforations, producing a cooling effect.
These technologies are quite effective, and inexpensive, which is why many automobile makers prefer them. You can find ventilation systems working on fans in various types of cars, starting with average priced sedans and ending with expensive SUVs. Their use is especially common in cars made for warmer regions or long distances.

Hybrid systems

Hybrid systems These systems are more sophisticated, because they combine ventilation with additional comfort features. For instance, some systems combine heating elements for more cold weather, or even massage elements to provide the best possible in-car experience. More advanced blower designs, with additional components, are often used in these systems.
A good example are Tesla seat ventilation systems offered in the Model S, where seat heaters are incorporated into the ventilation system. Such systems are growing popular among elite cars since there is always an effort to improve user experience.

Benefits of Having Ventilated Seats

After learning how seat ventilation systems operate, it is time to understand why you could need one in vehicles.

Comfort in Different Climates

The greatest advantage is without a doubt comfort. For instance, if you are in a humid state like Florida or are facing a heatwave in Arizona, dry and cool is the preferred state. Still, these systems are not specific to warm weather only; during colder seasons, these systems can assist in evenly spreading warmth in the vehicle alongside heated seats.

Health and Ergonomic Advantages

There is a health component as well. As opposed to heated seat systems, seat ventilation has its perks too. By keeping irritation at bay, seat ventilation systems help cool the user which results in little to no sweating. Some studies indicate that well ventilated car seats promote blood circulation which reduces the likelihood of the user experiencing discomfort or even numbing effects while on long rides. Warm and moist conditions are ideal for bacteria and fungi, which can also be avoided. With proper seat ventilation, growth can be prevented.
From an ergonomic perspective, a cooler seat eases fatigue. A cooler seat, as a result, lowers fatigue. The International Journal of Industrial Ergonomics conducted a study and thermal comfort provided something during high fatigue levels.

Improved focus while driving

As a result of comfort, you can relax and concentrate more on the road. This is particularly critical whilst taking long journeys or driving in congested traffic. Seat ventilation systems have the potential of improving safer driving because they enhance comfort and keep drivers cool.
