Air Conditioner is a tool capable of conditioning the air. In other words, AC Functioning Asthe desired air conditioning (cool or cold) and comfortable to the body. Ac More Widely used in tropical areas with air temperature conditions of relatively high (hot).
2.Komponen - Components of the AC
AC components grouped into 4 parts, the main component, supporting components,electrical, and coolant materials (refrigerants)
1. compressor
Compressor is a tool that serves to distribute the refrigerant gas to the entire system. If the analogy, how the air conditioning compressor such as the heart of the Human Body. The compressor has two pipes,, Namely Suction Pipe And Pipe press. And has 2 pressure area, low pressure and high pressure. There are three types of compressors, ie: pistoncompressor (Reciproacting) Centrifugal compressors and rotary compressors.
It functions as a condenser heat exchanger, refrigerant temperature decrease, and change the shape of the gaseous refrigerant into a liquid. The AC condenser is usually stored inoutdoor (outdoor). The condenser is usually cooled by fan (FAN), Fan is functioning exhalecondenser heat generated during the release of the Heat not absorbed by the refrigerant. In order for the heat release process can be faster, winding pipe condenser is designed and equipped with fins.
Capillary tube is the main component that functions lowers the refrigerant pressure andregulate the flow of refrigerant into the evaporator. The main function of the capillary tube is very vital because it connects two different pressures, ie high pressure and low pressure.high-pressure refrigerant before passing through the capillary tube will be changed orreduced tekananya. As a result of refrigerant pressure drop causes a decrease intemperature. In this section (capillary tube) refrigerant reaches the lowest temperature (the coldest). Capillary tube is located between the filter (filter) and Evaporator.
Functioning evaporator absorbing and transferring heat from air to refrigerant. As a result,realization of liquid refrigerant after passing through the pipe will kepiler transformed intogak. Simply put, the evaporator can say as a heat exchanger. Hot air around the air-conditioned reuangan absorbed by the evaporator and entered through the fins so that thetemperature of the air pipe coming out of the fins to be lower than the condition of all or amatch for. Air circulation, air-conditioned room set by indoor blower. Evaporator is usuallyplaced in the room.
1. filter or Strainer
Strainer or filter function to filter impurities carried by the refrigerant in air conditioningsystems, Manure who escaped from the filter due to damaged strainers can causeblockage of the capillary tube. As a result, the circulation of refrigerant to be interrupted.usually, the dirt is a plug pendingn systems, such as rust and metal flakes.
2. accumulator
Accumulator serves as a placeholder while the low-temperature liquid refrigerant andlubricant mixture evaporator. In addition, the accumulator controls the circulation of the refrigerant flow of material to get out of the compressor through the suction channel. To prevent liquid refrigerant from flowing into the compressor, accumulator condition the form of refrigerant remains in the form of gas. Because, as a form of gaseous refrigerant will be easier to get into the compressor and not damage the inside of the compressor.

3. Compressor Lubricant Oil
Lubricating oil or oil compressor in the AC system is useful to lubricate the compressor so that the parts do not wear out quickly due to friction. Additionally, lubricating oil serves to reduce heat in parts of the compressor. A small percentage of oil mixed with refrigerantcompressor, and then participate in the system circulates coolant through the condenserand evaporator. Therefore, compressor oil must have special requirements, which arelubricating, resistant to high temperature compressor, has a freezing point renndah, and no negative effects on the properties of refrigerants and air conditioning components in its path.

4. Fan (Fan or Blower)
In the AC component, located on the indoor blower is blowing cold air function that produced the evaporator. Fan or the fan is located in the outdoor section which cools therefrigerant in the condenser and to help release the heat at the condenser

1. thermistor
Thermistor is a temperature regulator. That way, the thermistor is able to set the compressor work automatically based on temperature changes. Typically, thermistormounted in the evaporator. Semikonduktro thermistor made from materials that are madein several forms, such as plate, bar, or granules, depending on the manufacturer of the AC. On the thermistor-shaped granules, has a diameter (approximately 3-5 mm). Then, a few grains of the thermistor is wrapped with a capsule made of glass (glass capsules).Furthermore, the glass capsule fitted with two foot terminal (pin). Because of its size is very small, grain shaped thermistor is able to react very quickly to changes in temperature.Thermistor is designed to have the prisoners whose value semaking shrink when the temperature increases. In the AC unit, there are two types of thermistor, namely roomtemperature thermistor and thermistor pipe evaporator. Room temperature thermistorfunction receives the response and gusts evaporator temperature changes. Pipethermistor serves to receive the pipe evaporator temperature changes.
Control PCB is a means to manage the overall work unit air conditioner. If the analogika,PCB control functions resemble the human brain functions. In the Control PCB componentconsists of a variety of electronic devices, sperti thermistor, sensors, capacitors, IC,transformer, fuse, switches, relays, and other electronic devices. Its function is also varied, ranging from controlling the indoor blower speed, the swing movement, regulatetemperature, length of operation (timer), to turn on or turn off air conditioners
Capacitors are electronic devices that serve as temporary storage of electrical charge.Said to be temporary, the capacitor will remove all the electrical charge contained in a sudden in a very short time. The amount of cargo that can be accommodated depending on the capacity of the capacitor. The unit of capacity of the capacitor is farad (F).Typically, capacitors function as a compressor drive the first time or starting capacitor.With the help of the starting capacitor, it takes only a split second or a very short time to make the compressor motor rotates at full speed. Long or short the time required depends on the amount of electric charge stored in the capacitor. After the compressor motor reaches full turn, automatically the electrical connections on the capacitor will be removed and replaced with a direct connection from the PLN. The capacitor will charge its cargo and will be reused at any time when the compressor turn on again. In the air conditioning unit, usually there are two starting capacitors, namely as a mover of the compressor and fan motor (fan). the AC-powered compressors 0.5 - 2 PK has a size of 15-50 nF capacitor start. At the fan motor (fan indoor or outdoor) have size 1-4 nF capacitor start.
3.Overload Motor Protector (OMP)
Motor Overload Protector (OMP) is an electric motor compressor safety device (usually found on the type of hermetic compressors). OMP Work is controlled by heat sensors made from a mixture of metallic and nonmetallic materials (bimetallic). Bimetallic rods is what opens and closes an electrical current to the electric motor automatically. When the bimetallic high electric current passed continuously or condition of the compressor is too hot, bimetal will open so that an electric current to the compressor will break. And vice versa. When the compressor temperature falls, bimetal will close, electric current will flow into the compressor so the compressor will return to work. OMP placement on hermetic compressors are of two kinds, namely OMP external (outside the body placed in the compressor) and internal OMP (placed in the compressor). Typically, External OMP is used for air-conditioning compressor engine that is not too large (0.5 to 1 PK), while internal OMP found in many large AC compressor engines (1.5-2 PK).
Electric motor serves to drive the fan (outdoor) and Blowers (indoor). The shape and size of indoor and outdoor electric motors are different. To help maximize the round, bothindoor and outdoor electric motor, capacitor start functioning required moving the firstelectric motor until it reaches a full turn. Furthermore, the start capacitor will be replacedby the current electricity to rotate the second electric motor.
5. motor Compressor The compressor motor functioning compressor engine moving. When the motor works, the compressor will serve as sirkulator material into the coolant throughout the cooling system.Generally, the compressor motor packed into one unti with kompresornya. Similar to thefan motor, compressor motor to start the beginning of the start capacitor also use the help.
