Belajar sirkulasi freon AC untuk pemula agar bisa servis atau perbaiki AC

Summary

In this video, the presenter explains the circulation process of refrigerant (preon) in an air conditioning (AC) system. Starting from the compressor in the outdoor unit, the refrigerant is pumped and travels through various components like the condenser, filter, capillary tube, and evaporator. The refrigerant undergoes a transformation from gas to liquid as it moves through the system, cooling the indoor environment. The process continues as the refrigerant cycles back through the compressor, ensuring continuous cooling. The presenter offers a clear and detailed explanation, with a promise to delve deeper in future videos.

Takeaways

• 😀 The refrigerant (preon) circulates through the AC system, starting from the outdoor unit.
• 😀 The compressor pumps the refrigerant under high pressure, pushing it to the condenser.
• 😀 In the condenser, the refrigerant releases heat and turns from a gas to a liquid.
• 😀 The refrigerant then passes through a filter to remove impurities and prevent blockages in the system.
• 😀 The capillary tube reduces the refrigerant's pressure, causing it to change back from liquid to gas.
• 😀 The EPAP (Electronic Expansion Valve) further controls the temperature and pressure of the refrigerant.
• 😀 The refrigerant travels to the indoor unit, where it absorbs heat from the air inside the room.
• 😀 Once the refrigerant absorbs heat in the indoor unit, it turns into gas and returns to the compressor.
• 😀 The cycle of refrigerant circulation continues to transfer heat from the inside of the building to the outside, providing cooling.
• 😀 The video provides a high-level overview of the refrigerant circulation in an AC system, with more details promised for future videos.

Q & A

What is the main function of the compressor in an air conditioner?

The main function of the compressor is to pump the refrigerant, or 'preon,' and keep it circulating through the system, from the condenser to the indoor unit and back.

What role does the condenser play in the refrigerant circulation process?

The condenser's role is to receive the refrigerant from the compressor, where it is then cooled and moves through various pipes before being filtered.

Why is the refrigerant filtered before passing through the capillary tube?

The refrigerant is filtered to prevent any debris or impurities from clogging the small capillary tube, which could hinder its function.

What is the purpose of the capillary tube in the AC system?

The capillary tube’s primary function is to transform the refrigerant from a gas into a liquid, allowing it to be properly cycled through the system.

What happens after the refrigerant exits the capillary tube?

After the refrigerant exits the capillary tube, it passes through the valve (called the expansion valve or 'palep') and enters the indoor unit where it is distributed through the evaporator.

What is the role of the evaporator (EPAP) in the air conditioning process?

The evaporator's role is to allow the refrigerant to expand and absorb heat from the air, which cools the space. It’s where the refrigerant evaporates and transforms into a gas.

How does the refrigerant move from the indoor unit to the compressor?

After the refrigerant passes through the evaporator and absorbs heat, it exits via the larger pipe, entering the valve and then flowing into the compressor's suction side.

What is the function of the accumulator in the AC system?

The accumulator ensures that only refrigerant in gas form enters the compressor, preventing any liquid refrigerant from damaging the compressor.

How does the refrigerant return to the compressor after circulating through the system?

After passing through the accumulator and the expansion valve, the refrigerant is sucked back into the compressor’s suction side, where the process starts again.

Why is it important to monitor the pressure of the refrigerant in the system?

Monitoring the refrigerant pressure helps ensure that the system is functioning properly. It helps to detect issues such as leaks or improper refrigerant levels, which could impact the cooling efficiency.
