Know about Anti-Lock Braking System

An anti-lock braking system (ABS) is a automobile safety system that lets the motor vehicle wheels continue interacting with the road surface as directed by steering inputs given by driver, and while braking, preventing the wheels from locking up. In other words, it is a technology designed to help the driver to maintain some steering ability and avoid skidding or slipping while braking.

The anti-lock braking system was introduced in the mid 1980’s and has become standard equipment on the majority of the four wheeler vehicles such as cars, trucks and multipurpose vehicles. This helps maintain directional stability and helps you steer while maximizing braking.

The primary function of the ABS is to prevent the wheels getting locked up. This is possible by modulating automatically brake pressure in the event of an emergency. Preventing the wheels from locking helps you maintain control over steering and to stop the vehicle in the shortest possible distances under most conditions.

In emergency situations, you can sense the pulsation in the brake pedal during ABS operation and is indicated by a fall and rise height of brake pedal and a clicking sound. ABS system consists of some following components:

  • Speed sensors.
  • Brake calipers.
  • A hydraulic motor.
  • Anti-lock brake control module.
  • Hydraulic control module.

Sensors calculates the speed of the vehicle and the difference of the rotational speeds of the braked wheels and this information is converted into electrical signals. If a wheel gets locked up, the hydraulic valves reduce the effect of brake on that wheel. This prevents skidding and allows you to maintain steering control. Read the rest of this entry »

Know the Importance of Humidity Control by Your Air conditioners

Centrifugal FanAir conditioners are equipment designed to distribute fresh air, comfortable room temperature, ventilation and humidity. These conditions are necessary for maintaining fresh air in the house to help one to stay active, healthy and work efficiently.

According to experts of HAVC (Heating, ventilation and air conditioning), good air conditioners maintain comfortable room temperature of 27O Celsius and humidity between 40% to 60%. When such optimum levels are not maintained in you room, you may not get sufficient cooling from air conditioners no matter how efficient the cooling the room is. When humidity is not maintained we tend to sweat slowly, this makes the difficult to lose heat, which makes us uncomfortable even under less hot conditions.

Most advanced air conditioners are equipped with dehumidifiers that efficiently remove excess moisture in the room. While purchasing air conditioners one needs to observe whether air conditioners are equipped with humidity monitor, dehumidifier and that it matches with the size of your room. Among different types of air conditioners central air conditioners are according to a reliable technology in maintaining exact humidity with better ventilation and fresh air supply.

Since humidity affects you in many ways from your health to efficiency of air conditioners, you may have to keep a regular track of humidity levels in your house using humidity meters or use of air conditioners equipped with dehumidifiers.
