Describe the Operation of the Typical Automotive Air Conditioning System

When the refrigerant is drawn into the compressor it is in. The switch inside the thermostat closes.

How A Car Air Conditioning System Works Nicely Explained Mechanical Booster

Commonly referred to as the heart of the system the compressor is a belt driven pump that is fastened to the engine.

. Full PDF Package Download Full PDF Package. Heres a quick rundown of how each part of a cars AC contributes to air conditioning operation in Madison TN. 27 Full PDFs related to.

Air conditioners work on the principle that liquids absorb heat when they become a vapor evaporate. Defined as discharge and suction. Some air conditioning systems are designed to prevent the compressor from being engaged when the level of refrigerant in the system is low.

The ac compressor initiates the high-side of the system where it is compresses. Describe the operation of the typical automotive air-conditioning system. Servo motor and blower motor as shown in the timing chart below.

32 Central Air Conditioning System. Automotive air conditioning systems operate under variable loads in order to provide passengers comfort under wide outside temperature conditions. Automobile air conditioning system.

An air conditioning system generally consists of five mechanical components. Automotive Air-conditioning and Climate Control Systems. Describe the operation of the typical automotive air-conditioning system.

It is the most important types of air conditioning system it uses when the required cooling capacity 25TR or more. Following are the application of Air Conditioning. Most central air conditioning systems include a hot side outside your home and a cool side inside your home.

Most air conditioning systems have five mechanical components. The automotive air conditioning system consists a refrigeration system air circulation and distribution system and a control system. It is responsible for compressing and transferring refrigerant gas.

The air circulating system circulate this cooled air into the car which include blower air duct etcThe controlling system. A chemical refrigerant in the system absorbs the unwanted heat and pumps it through a system of piping to the outside coil. That energizes the Y and the G circuit in the thermostat or the compressor contactor and the fan circuit.

The air conditioning system gets filled with refrigerant gas known as Freon or R135A. An air conditioner follows the following basic sequence of operation. Each of these components serves a different purpose.

As we have already mentioned that air conditioning system inside a cabin is required to provide a relaxed and fatigue free atmosphere to the. Refrigerant has the ability to change its physical properties during compression which as youll see momentarily is crucial to the operation of. Topic Discussedhow an Automotive Air Conditioning System works along with the different parts and functions of different components of an Automotive Air Co.

The greater the temperature difference between the two the more heat flows. Automotive Air-conditioning and Climate Control Systems. All automotive air conditioning systems are nearly closed loops with a high-pressure side and low-pressure side.

On the diagram use a blue pen to indicate the flow of air when the system is set to the hot position and a pencil to indicate when the system is set to cold. Learn more about the repetitive cycle of the system from the list of air conditioner components and the AC parts. Input to the AC amplifier the AC amplifier controls the compressor.

Commonly we remove heat from the inside and take it outside. A short summary of this paper. In an air conditioning system this hot gas is then circulated through a series of tubes where it dissipates its heat.

It uses when the airflow is more than 300 m³min or different zones in a building are to be air-conditioned. The AC system is split into two sides a high pressure side and a low pressure side. Auto Air Conditioning Design.

The basic theory states heat will flow from the warmer object to the colder one. Low-pressure R134a vapor entering the compressor is compressed to become high pressuretemperature R134a vapor. The freonrefrigerant resides in the ac system.

The major components of the automotive air conditioning system are a compressor an evaporator a condenser and an expansion valve. First take an affordable inert gas like freon and place it in a sealed system. The compressor is the heart of the air conditioning system.

As the high pressuretemperature vapor travels through the. And by the laws of physics a pressurized gas heats up by absorbing energy around it. The air conditioning system is made up of the following components.

With motor assembly air inlet control servo motor air outlet control. As the refrigerant absorbs heat it. This gas is then pressurized using a compressor.

This is then circulated along with lubricant oil to the condenser. Having a good understanding of how the components work can help to explain the methods of repairs in the air conditioning system. The thermostat set to cooling mode calls for cooling.

Well start with the high-pressure side as it leads from the engine to the passenger compartment. The compressor is a pump driven by a belt attached to the engines crankshaft. It actually takes the heat and moisture out of the air that is already in your car leaving behind cooler air.

The now-cool air is blown into your ducts to be distributed through your home. Describe the operation of the heating and ventilation system illustrated in figure 1 of Appendix I. The compressor continuously cycles on and off to meet the cooling requirements of the passenger compartment and is mounted.

The hot side generally consists of a condensing coil a. Condenser Coil Hot Evaporator Coil Cool Chemical Refrigerant. A fan blows air over the coil and the refrigerant in the coil absorbs heat from the air.

The fan located in the outside unit blows outside air over the hot coil transferring heat from the refrigerant to the outdoor air. D This control usually operates for approximately 3 minutes. This air conditioning system takes power from the engines crankshaft and is operated by the passengers from the cockpit by pressing the button assigned to this system.

2marksState the role of the electromagnetic clutch used on the air condition compressor 1mark h. Compressor condenser evaporator orifice tube or expansion valve and an accumulator or receiver-drier. Why do We Need an Automobile or Car Air Conditioning System.

The refrigeration system cool down the air which include many other parts like compressorcondenser etc. Under medium operating conditions temperature stratification in the air stream at the exit of the evaporator is observed which might lead to passengers discomfort. Cold refrigerant is pumped through the evaporator coil.

All ac systems are designed to pump heat from one point to another.
