As an automobile engineer we will define it as, an atmosphere that provides relax and causes less fatigue to a human which can be achieved by an air conditioning of the particular cabin that includes maintaining the cabin’s temperature between 20 to 25 degree centigrade and removing the humidity from the cabin’s atmosphere, in short by fitting air conditioner in that cabin but now the question arises How is it possible in a car’s cockpit? Most of their customers operated limousines and luxury cars. As the Freon goes through the expansion valve it returns to a low-pressure gas and rapidly cools in the evaporator. It is also known as the heart of the AC system, A compressor provide pressure rise to the refrigerant to convert the vapour refrigerant into liquid refrigerant which in turn enables the further flow of the refrigerant through condenser. Usually three to four pounds of refrigerant is used to fill the system in most vehicles. In its gaseous form, refrigerant can absorb a lot of heat. Operated by an AC button on the dashboard, the air conditioning system is able to heat or cool air flowing into the car. Without the heating and air conditioning systems in today’s modern vehicles, we would all be miserable driving to our destinations. Brian Cooley You could look at the red and blue colors and ballpark what you wanted via analog switchgear and estimation. Anti-lock Braking System (ABS) – Working Principle, Main Components with Advantages and Disadvantages, How Automatic Transmission Works? Energy is consumed by the parts of the system that heat and cool the air and movement of air with fans requires energy. This is due to the rapid expansion of the compressed gas. Since the advent of the automotive air conditioning system in the 1940’s, many things have undergone extensive change. How a car’s cooling system works. Of course I could tell you to get the system checked BEFORE you ventured out, but what good would that do now? Why do We Need an Automobile or Car Air Conditioning System?

Let’s take a look at how both systems work to keep us comfortable all year round. The heater fan blows air through the heater core and into the passenger compartment of your car. HVAC system is basically an assembly of various types of equipment installed together to provide heating and cooling along with indoor climate control. It allows you to create a comfortable environment by controlling the blower motor’s speed, the amount of heat in your car, and the direction of air movement. The purpose of the compressor is to pressurize the air conditioning system and circulate the refrigerant. air condition Car air conditioning is a system within your car that allows you to cool the interior air of the vehicle in hot weather, providing for a cooler environment for the occupants. Your filter is the second part of the air return in which the air is drawn through. Modern cars are designed to have a constant through-flow of fresh air that keeps the interior atmosphere pleasant even with all the windows shut. With the push of a button or the slide of a lever, we make the seamless transition from heating to cooling and back again without ever wondering how this change occurs. It is a device that looks like another heat exchanger and is place just behind the AC vent over a dash board of a car, an evaporator takes heat from the passenger’s compartment and convert the liquid refrigerant sent by the expansion valve into vapor, which in turn provides cooling through the fan inside a passenger’s cabin. Whether you use your car’s air con a lot or hardly ever at all, air con gas will continue to permeate through the system over time so an air con service every two years will keep the gas topped up and the system lubricated so you always have a cool blast ready when you need it most. The car occupies the daily universe of our society; however, noise pollution, global warming gas emissions, and increased fuel consumption are constantly increasing. start the blower). If you need to do some work on your car or truck's AC system, be sure to have a repair manual specific to your vehicle. Pankaj Mishra is a blogger by passion and Mechanical Engineer by profession. Note – Thermal expansion valve is used in vehicles that enable the passenger to change the temperature according to the requirement, by just adjusting the knob provided over a dash board in passenger’s cabin. Feeling curious? It controls the movement, quality and temperature of air to ventilate, warm and cool the organism. The HVAC system is complex to say the least. – Best Explanation Ever, How Wind Power Plant Works?- Complete Explanation, How Synchromesh Gearbox Works? 1. This was the year Chrysler made big advances in their air-temp trunk mounted cooling system. The purpose of the system is to remove hot air from the inside of your vehicle.
