In this section, we will take a brief look at some of the viable options which are ideal for use as an air conditioner PCB board. So, without further ado, let us dive into the discussion of available options which are both feasible and practical.
Options for an Air Conditioner PCB board
1. High Temperature PCB
PCB board manufacturers are trying their best to maximize the performance of their PCBs. We live in an age where we manufacture more and more electronic devices every day. Appliances such as an air conditioner are infrequent use. So, these appliances have high power densities and hence they operate on relatively higher temperatures. Hence, we need to observe special care that the dielectrics and conducting material we choose for our PCB are suitable for the job. When we are dealing with high temperatures then we get to observe an increase in conducting resistance and therefore current losses.
In the case of an HVAC system such as an air conditioner, this effect is even more prominent. Therefore, we get to observe a significant change in impedance properties and consequently a drastic change in thermal properties. Hence, the performance of the air conditioning system might decrease and might ultimately result in a severe system failure.
If we use normal PCBs for use in air conditioners then they might not work well. The primary reason for this is that normal PCBs cannot handle the extreme temperature fluctuations and therefore they are often prone to thermal stresses on top of mechanical stresses. Thermal stress takes place when an object is heated and cooled rapidly without any rest period. This can lead to a generation of cracks in the PCB which will ultimately contribute towards failure. The chances increase significantly if the number of heating and cooling cycles increases.
Additionally, if the operating temperature is very large then the PCB board might melt instantaneously. Hence, we need to go with High Frequency PCB because they have good thermal conductivity. This means that we can use them at very high operating temperatures and they won’t show failure. This is because heat can easily flow through High Temperature PCB. Therefore, these PCBs are indifferent to thermal stresses and the consequent cracking. On top of that, they are immune to localized heating phenomenon because heat is evenly and uniformly distributed in a High Temperature PCB.
2. High Frequency PCB
Most air conditioners today are often part of smart home systems. This means that you can control their cooling temperature by using the dedicated remote. However, some smart air conditioners even allow you to control their cooling temperature and other performance parameters even when you are not at home. In this case, you have to use a dedicated app for controlling the cooling temperature and other performance parameters of the air conditioner. An air conditioner is able to do this because it has the capability to process signals sent to it from the remote or the cloud servers.
This signal processing means that there are additional cycles on top of the thermal cycles of the HVAC system. If a device is subject to such cycles then the chances of system failure are considerably high. The reason for this is that such high operating cycles means that the electronic components will have to deal with very high frequencies.
Such high frequencies can not only degrade the electronic performance but also contribute towards noise inclusion. Therefore, it is empirical that we use an air conditioner PCB board which is not prone to consequences from such high frequencies. Hence, High Frequency PCB seems like a great fit for use in air conditioners. The reason for this is that they come with special laminates that allow easy operations at high frequencies. On top of that this special laminate allows for better able to handle the high heat transfer through the PCB board. The biggest benefit of using High Frequency PCB is that your air conditioning system will incur minimum noise.
3. Rigid PCB
Advanced appliances such as an air conditioner involve high-end mechanics and are basically HVAC systems. So, the components we use in them are often subject to a lot of thermal stresses. If we use a normal PCB in an air conditioner then chances are that its performance will decrease and the entire system might collapse. An air conditioner involves numerous heating and cooling cycles. This means that the normal PCB will have to face frequent thermal expansion and thermal contraction.
Therefore, the normal PCB will lose its dimensions, shape, and form. If this happens then the PCB will fail and its functionality won’t meet the set benchmark. Therefore, we need an air conditioner PCB board that has remarkable dimensional stability and doesn’t change its shape or form under any conditions.
So, we can choose a rigid PCB for use in any given air conditioner because it has amazing dimensional stability and is not prone to deformation due to thermal stresses. These kinds of PCB boards are manufactured by using a rigid substrate. This rigid substrate is responsible for supplying strength and durability to this kind of PCBs. Hence, a rigid PCB has a higher lifespan and is able to function well even on elevated temperatures. That is why it is the perfect fit for uses in HVAC systems such as an air conditioner.
Air conditioner PCB board
Thousands of years ago people were living in harsh environments and the intense summer heat was simply unbearable. However, we don’t have to endure such conditions thanks to the invention of smart devices such as the air conditioner PCB board. These PCB boards make it possible to design and develop high-end HVAC systems such as an air conditioner. Therefore, whenever we feel like that the heat is beyond our endurance level, all we have to do is to turn on the air conditioner.
We might not realize it simply due to our casual attitudes or plain ignorance, however, it is not an easy task to design and manufacture an AC. This immense task requires superior design skills of talented engineers and precise handling by trained workers. On top of that, we need many important components and we need to come up with efficient circuit designs. If we were to simply embed each component into the circuit individually then it is an impractical approach. Therefore, we use special devices known as the air conditioner PCB board. These allow us to simultaneously embed several stacks of components in layer form. Hence, it is practical, economical, and efficient. In this article, we will take a look at the significant roles and functionalities of the air conditioner PCB board.
Working of an Air Conditioner
An air conditioner works by removing heat from a certain space and hence it cools it down. So, we come to wonder how an air conditioner manages to do this. Well, an air conditioner removes the hot air from a room or a building. After that, it injects cool air into the same room or building. That is why an air conditioner always comes in two separate units. These two separate units include the condenser and the evaporator.
We place the condenser in the indoors (the room or building which we want to cool down) and we place the evaporator in the outdoors (so that it has access to the outer air). The condenser extracts the hot air from the room or the building and ejects it out through the evaporator. At the same time, the condenser uses liquid gases to cool the air coming from the outside and then injects it inside the room or the building.
Both the condenser and the evaporator are connected by sophisticated parts and modules such as a compressor which complements the condenser. There is also an accumulator which accumulates the cooled air before injecting it inside the room or the building. We also have a compressor which compresses the hot air before sending it outside the room. There is an expansion valve as well which primarily serves to control the contraction and expansion of the incoming and outgoing air and gases. The condenser features a fan which makes it easier to inject the cool air into the room. Similarly, the evaporator features a blower which makes it easier to eject the hot air from the room to the outside air.
The requirements of PCB boards in an Air Conditioner
There are many electronic circuits and components in an air conditioner. So, there are many electronic processes occurring at the same time. Therefore, we have to use sophisticated and smart control and optimization processes. We implement these processes by using advanced electronics. Hence, we have to rely on an air conditioner PCB board so that we can implement these electronic circuits and embed the required components.
1. Able to Withstand Temperature Fluctuations
Since an air conditioner is an HVAC system, therefore, we often observe rigorous and intense heat transfer and temperature fluctuations within the air conditioner. Hence, we need an air conditioner PCB board that can endure these fluctuations in temperature and the intense heat transfer. So, a high temperature is ideal for use in an air conditioner. A high temperature PCB will have the ability to withstand these rigorous thermal conditions.
2. Ability to Withstand a large number of Cycles
The air conditioner removes the warm air from inside the room. At the same time, it takes the air from the outside environment and injects it inside the room after cooling it. For this purpose, we often use liquid gases to cool the air. These processes often involve intense heat cycles such as condensation, compression, expansion, contraction, accumulation, and finally evaporation. These processes are often performed in a cycle and in a given day theses cycles are repeated hundreds of times. Hence, we need an air conditioner PCB board which has the ability to withstand these large number of cycles. Therefore, a high frequency PCB is ideal for use in an air conditioner. This is because the high-frequency PCB board is able to withstand numerous cycles without incurring any strain.
3. Ability to maintain their shape, form, and dimensions
An air conditioner is a prime example of HVAC systems that involve advanced thermodynamics and thermal changes. These large changes in temperature can affect the shape and form of any electronic component. If this occurs then the certain electronic component might lose its functionality. Consequently, it will disrupt the electronic circuit and network. Subsequently, the system of the entire air conditioner will collapse. Therefore, we need an air conditioner PCB board that has superior dimensional stability so that it doesn’t undergo thermal expansion or thermal contraction.
Hence, we need a PCB board that has the ability to maintain its form, shape, and dimensions. So, a PCB with considerable rigidity makes sense because it is indifferent to dimensional changes due to any reason. Therefore, a rigid PCB board is ideal for use in an air conditioner. This is primarily due to the fact that a rigid PCB board is very capable of maintaining its shape, texture, consolidation, form, and dimensions. On top of that, a rigid PCB is impartial to thermal cycles because it doesn’t show considerable thermal expansion or thermal contraction.
