AC Components

AC Main Components include:
1 Compressor
A compressor is a tool that serves to deliver gas refrigerant throughout the system. If the analogy, how the air conditioning compressor is just like the heart in the Human Body. Compressor That Has 2 Pipe,, Suction Pipe And Pipe press.
And Has 2 pressure region, ie low pressure and high pressure. There are three types of compressors, ie: Compressor Torak (Reciproacting) Centrifugal compressors and rotary compressors.

2 Condenser
Functioning as a condenser heat exchanger, lowering the temperature of refrigerant, and change the shape of the refrigerant gas into a liquid form.
In the air conditioning condenser is usually stored in the outdoors (outdoor). By Fan cooled condenser usually (FAN), Fan is functioning exhale condenser heat generated at the time of the release of Heat absorbed by the refrigerant tub. The release process so that heat can be faster, winding pipe condenser is designed and equipped with fins.

3 Capillary Pipe
The capillary tube is the main component that serves to decrease the refrigerant pressure and regulate the flow of refrigerant to the evaporator. The main function of the capillary tube is very vital because it connects two parts of different pressures, namely high pressure and low pressure. High pressure refrigerant before passing through the capillary tube will be changed or lowered pressure. As a result of a decrease in pressure causes a decrease in the temperature of the refrigerant. In this section (capillary tube) refrigerant reaches the lowest temperature (the coldest). The capillary tube located between the filter (filters) and Evaporator.

4. Evaporator
Evaporator and absorbs heat from the air stream to the refrigerant. Consequently, realization of the liquid refrigerant after passing through the pipe kepiler will change into a gas. 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 the temperature of the air pipe coming out of the fins being lower than all or cold conditions. Air circulation air-conditioned room set By the indoor blower. Evaporators are usually placed in the room.

Supporting AC Components Among them:
1 Strainer or Sieve
Strainer or filter function to filter impurities carried by the refrigerant in the air-conditioning system, which escaped Dirt filter for damaged strainer can cause blockage of the capillary. As a result, the circulation of the refrigerant becomes interrupted. usually, the dirt stopper pendingn systems, such as rust and metal flake.

2 Accumulator
Accumulator serves as a reservoir while the low-temperature liquid refrigerant and lubricant oil mixtures evaporator. In addition, the accumulator controls the circulation of material flow of refrigerant to be out of the compressor through the suction channel. To prevent liquid refrigerant flowing to the compressor, accumulator condition refrigerant remains in the form of a gas. Therefore, when the form of gaseous refrigerant will be easier to get into the compressor and does not destroy the inside of the compressor.

3 Compressor Lubricant Oil
Lubricating oil or oil in the compressor air conditioning system is useful to lubricate the compressor section to prevent rapid attrition. Additionally, lubricating oil serves to reduce the heat in the compressor section. A small portion of the oil mixed with refrigerant compressor, then participated in the cooling system circulates past the condenser and evaporator. Therefore, the compressor oil must have special requirements, which is to lubricate, resistant to high temperature compressor, has a freezing point renndah, and no negative effects on the properties of the refrigerant and air conditioning components in its path.

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

In AC Electrical Components:
1 Thermistor
Thermistor is a temperature regulating device. By doing so, the thermistor is able to regulate the compressor automatically based on changes in temperature. Typically, thermistors mounted on the evaporator. Semikonduktro thermistor is made of materials that are made in several shapes, such as discs, bars, or granules, depending on the manufacturer of the AC. In granular thermistor, has a diameter (approximately 3-5 mm). Then, a few grains of the thermistor wrapped in a capsule made ​​of glass (glass capsules). Furthermore, the glass capsule fitted with two legs terminal (pin). Because the size is very small, granular thermistor able to react very quickly to changes in temperature. Thermistor is designed to have a resistance whose value decreases when the temperature increases semaking. In the air conditioning unit, there are two types of thermistor, ie room temperature thermistor and evaporator pipe thermistor. Room temperature thermistor function receives the response and gusts evaporator temperature changes. Pipe thermistor functions accept changes in temperature on the evaporator pipe.

2 PCB Control
PCB Control is a tool set working air conditioning unit overall. If in analogika, PCB control function resembles the function of the human brain. In the Control PCB component consists of a variety of electronic devices, just as thermistor, sensors, capacitors, ICs, transformers, fuses, switches, relays, and other electrical appliances. Its function is also varied, ranging from indoor blower speed control, swing movement, set temperature, operation time (timer), to turn on or turn off the AC.

3 Capacitors
The capacitor is an electronic device that serves as a temporary storage of electrical charge. Said to be temporary, the capacitor will discharge all the electrical charge contained abruptly in a very short time. The amount of charge that can be stored depends on the capacity of the capacitor. The units of capacity capacitor is farad (F). Typically, capacitor functioned as a first mover or compressor starting capacitor. With the help of the starting capacitor, it takes only a split second or so short to make the compressor motor spinning at full speed. Long or short amount of time depends on the amount of electric charge stored in the capacitor. After the compressor motor reaches full rotation, automatic electrical connections on the capacitor will be removed, and replaced with a direct connection from the PLN. The capacitor will charge charge

and will be used again at any time when the compressor turned on again. In the air-conditioning units, usually there are two starting capacitors, namely as a driver of compressor and fan motor (fan). AC powered compressor 0.5 - 2 PK have start measuring 15-50 nF capacitor.
At the fan motor (fan indoor or outdoor) have start measuring 1-4 nF capacitor.

4. Motor Overload Protector (OMP)
Motor Overload Protector (OMP) is a safety device electric motor compressor (usually found in the type of hermetic compressors). Work OMP controlled by heat sensors made ​​of a mixture of metal and non-metal (bimetal). Bimetallic rods that opens and closes automatically electric current to the electric motor. When an electric current is passed bimetallic continuous high or condition of the compressor is too hot, the bimetal will be open so that the electric current to the compressor will drop out. Vice versa. When the compressor temperature dropped, the bimetal will be closed, electric current will flow to the compressor so that the compressor will return to work. Placement OMP in hermetic compressors are of two kinds, namely external OMP (the compressor is placed outside the body) and internal OMP (placed in the compressor). Typically, External OMP is used for air-conditioning compressor machine that is not too large (0.5-1 OD), whereas the internal OMP abundant in large air conditioning compressor engine (1.5-2 PK).

5. Electric Motors
Electric Motors serves to drive the fan (outdoor) and Blowers (indoor). The shape and size of the electric motors of different indoor and outdoor. To help maximize the rounds, both in indoor and outdoor electric motor, capacitor start functioning needs drive the first electric motor to achieve full rotation. Furthermore, the function of the start capacitor will be replaced by a current of electricity to the electric motor rotating both.

6 Motor Compressor
Compressor motors drive the machine functioning compressor. When the motor works, the compressor will serve as coolants circulators headed to all parts of the cooling system. Generally, the compressor motor is packed into one unti with the compressor. Similar to the fan motor, compressor motor to start early also use the help of a start capacitor are mounted parallel between running and starting windings.
