Air conditioners have become essential to one’s daily life, especially if you live in hot and humid places. While most people may only think of A/C for its external benefits, what about the technology behind these devices? Indeed, its internal parts play a crucial role in its optimal performance. Printed circuit boards (PCBs) are one of these crucial components and serve as the brain of the A/C. This feature will explain how and why printed circuit boards are necessary for air conditioners. In addition, we will talk about how the advancements in its technology have made air conditioners more efficient and reliable. All these and more, so you can better understand how your AC works from the inside.
The Role of Printed Circuit Boards in Air Conditioners
Printed circuit boards act as the primary command center of air conditioners. It aids in temperature and fan speed control and monitor compressor operation. Without PCBs, air conditioners cannot function properly. If that is the case, we would not be able to enjoy the cooling comfort that we got to depend on.
PCBs convert the alternating current (AC) from the power supply into the direct current (DC) needed to fuel the air conditioner’s components. Apart from that, they also house and manage the microprocessors and sensors. It allows for precise control over the air conditioner’s operation. This precision control helps air conditioners run more efficiently. And that may lead to cost savings on energy bills and a longer lifespan for the unit.
Types of Printed Circuit Boards Used in Air Conditioners
For a better understanding, let us look at the different types of PCBs for air conditioners and how they help us to stay cool in hot weather.
Main PCB: This type of PCB serves as the brain of the air conditioner, controlling the overall operation of the unit, including temperature regulation, fan speed, and compressor operation.
Inverter PCB: Inverter PCBs are used in newer air conditioners with inverter technology. These PCBs control the speed of the compressor motor, allowing it to run at variable speeds. At the same time, they can adjust the cooling output according to the room’s temperature and humidity.
Display PCB: Display PCBs show the temperature, fan speed, and other settings on the air conditioner’s control panel.
Power PCB: Power PCBs convert the AC power from the electrical outlet into the DC power needed to operate the air conditioner’s electronic components.
Sensor PCB: Sensor PCBs monitor the temperature and humidity levels inside and outside the air conditioner. With this data, the main PCB can adjust the cooling output to match the needs of your living space.
Advancements in PCB Technology for Air Conditioners
There have been several advancements in PCB technology for air conditioners. Some of these include:
Surface-mount technology (SMT): This allows for placing smaller components on the PCB, resulting in a smaller overall size.
Micro-vias: These smaller holes drilled into the PCB allow for more routing space, making the PCB more compact.
Miniaturization of components: The advancements in SMT allow the use of smaller components, which results in a smaller overall size for the PCB.
Use of advanced materials: Advanced materials such as high-temperature laminates and metal-core PCBs are now available for use in air conditioners to increase their reliability and durability.
Repairing Air Conditioner Printed Circuit Boards
PCBs can fail for various reasons. Overheating, power surges, or physical damage can all be potential causes of failure. When a PCB fails, it can result in poor cooling performance or no cooling at all.
Regular A/C maintenance and inspection of PCBs can help make sure they stay in good condition and last a long time. Still, when breakdowns do occur, you have two options: repair or replace the faulty PCB. Yet, your decision depends on the severity of the damage. In some cases, replacing the entire board might be more cost-effective than attempting to fix it. Whatever the case may be, carefully check the A/C to ensure a safe and efficient operation.
