In recent years, smog has become more and more serious, people began to worry about the health of themselves and their families, so air purifiers and fresh air systems have become more and more concerned about air quality products. But for these two products, what many people don't know is that although they are of the same kind, they are very different. If you still can't decide, let Xiaobian explain it to you one by one.
air purifier
The principle of the air purifier can be basically called “internal circulationâ€. The air purifier draws the surrounding air into the machine through the fan, filters out some particles and other pollutants in the air through the filter, and then discharges the filtered air. A small cycle of "dirty air" to "clean air" is formed to achieve air purification.
In the closed state of the air purifier, the carbon dioxide generated by the human body's breathing cannot be discharged in the closed environment of the closed door and window. It can only be "infinitely circulated" indoors. Over time, the indoor carbon dioxide content will increase, and chest discomfort, headache and other discomfort will occur.
The indoor environment is not exposed to fresh air, the air cannot be replaced, and formaldehyde cannot be discharged outside in time. In the case of low indoor ventilation, the formaldehyde content will increase the intensity of the emission. The measured data shows that under certain conditions, the concentration of formaldehyde in the air in the small living room can be above the standard allowable level, and the release period is relatively long. The research of Yokohama National University in Japan shows that the release period of indoor formaldehyde is 3-15 years.
In the process of use, the small purification area and slow wind speed are also problems that people gradually find. Under a certain space in the room, the purifying area of ​​the air purifier can only reach 60 square meters, and the purification frequency is as low as 6h/time, which determines that the basic demand for breathing cannot be met. Unless you choose to place multiple air purifiers in your home, you will not be able to achieve full house purification.
In summary, it is not a complete negation of the purification effect of the air purifier, the air purifier also has the ability to purify, but in principle brings some limitations. This is why more and more people choose new fan systems.
New fan
The working principle of the fresh air system is that the outdoor air is piped to the inside of the machine, and then converted into fresh air into the room through multiple filtration inside the machine, and then the indoor dirty air is discharged outside the room through the micro-air pressure inside and outside. If the function of the air purifier is to purify the indoor air, then the fresh air system has the function of purifying at the same time, and also has the function of ventilation and ventilation.
The working principle of the fresh air system determines that it is not a range of purification, but space, that is, the whole house is cleaned, and the door and window are not opened in time, and the effect of “passing the wind†can be achieved. Compared to the air purifier's 6h/time, the fresh air system takes only 2 hours to keep the indoor air in the standard air range. The purification area depends on the amount of air volume, and the large air volume is also one of the advantages of the fresh air system. High-quality filter screen is used for efficient air filtration, and the purification efficiency is ensured without considering the trouble of frequently changing the filter screen.
What are IC Sockets?
Most of our everyday electrical devices contain integrated circuits (ICs) or chips which are installed on the printed circuit board (PCB). Most chips are soldered directly onto the board but sometimes they need to be interchangeable, or removed, and this is when an IC socket is used.
The IC socket fits onto the board and holds the chip, protecting it from heat damage which could be caused by soldering. Programmable chips are a great example where IC sockets are used, allowing removal for testing, programming or replacement due to failure.
IC (Integrated circuit) Sockets
IC Sockets connector is designed to provide a compressive interconnect between component leads and a printed circuit board (PCB). This connector is designed to provide a compressive interconnect between component leads and a printed circuit board (PCB). It simplifies the board design, enables simple reprogramming and expansion and easy repair and replacement, and offers a cost-effective solution without the risk of direct soldering. With a wide range of solutions for land grid array (LGA) and pin grid array (PGA) sockets, this connector features contact tip geometry optimized to reduce risk of contact damage during handling and package installation.
Antenk offer a comprehensive range of DIP, SIP and PGA sockets to suit most multiple electrical applications.
Types of IC Sockets
DIL /DIP– Dual in-line. These have two parallel rows of pins, available in various numbers to match the relevant IC and are normally very cost effective. A larger socket can be created by placing two smaller ones together, end-to-end, e.g. two 8-pins become 16-pin.
SIL/SIP – Single in-line. This socket has a single line of pins and are frequently used in smaller applications like resistor arrays or boards with short lead pins, such as a desktop computer. There are many different sizes and attributes available.
PGA – Pin Grid Array Sockets. Complex printed circuits are too valuable to risk direct soldering to expensive integrated circuits (ICs). Using a socket is the answer. The use of sockets offers advantages that prove cost effective and simplify board design.
DIMM – Dual In-line Memory Module. Random Access Memory (RAM) can be easily installed in computers or laptops using DIMM sockets. These are important components that help to ensure reliable connectivity. They have two separate rows of electrical contacts or pins on either side. It`s a general rule that the more pins the higher the RAM it supports. There are various pin sizes available.
SIMM – Single In-line Memory Module. These have a single row of pins which connect memory modules to circuit boards. They are space saving and can be installed at predetermined angles with positive polarisation to prevent memory modules from being inserted incorrectly. They are used mainly in older computers dating from the 1980s to late 1990s. Available in various sizes and number of pins.
IC Sockets Connector/Integrated Circuit Sockets Typical Applications
In notebook and desktop computers, LGA sockets feature a robust bolster plate for reliable connection to the microprocessor package while limiting PCB bowing during compression.
In servers, our mPGA and PGA sockets -- with custom arrays available in more than 1,000 positions --offer zero insertion force (ZIF) interface to the microprocessor PGA package and attach to the PCB with surface-mount technology (SMT) soldering. Antenk's IC sockets are designed for higher performance CPU processors.
