Precision air conditioning for server rooms can provide a constant temperature and humidity environment for the server room, in many important work, information processing is an indispensable part, so the normal operation of the company can not be separated from the constant temperature and humidity of the data room. IT hardware generates an unusual concentrated heat load, and at the same time very sensitive to changes in temperature or humidity. Fluctuations in temperature or humidity can cause problems such as garbled processing and, in severe cases, complete system downtime. This can cost a company a great deal of money, depending on the duration of the system outage and the value of the data and time lost. Standard comfort air conditioners are not designed to handle the concentration and composition of heat loads in data rooms, nor are they designed to provide the precise temperature and humidity set points required for these applications. Precision air conditioning systems are designed for precise temperature and humidity control. Precision air conditioning systems are highly reliable, guaranteeing continuous operation of the system throughout the year, and have the maintainability, assembly flexibility, and redundancy to ensure that the data room air conditioner operates normally throughout the seasons, and the Schneider Ulli dedicated air conditioner, which can fully satisfy a variety of user needs:
1. AMICO Series and Neptune series: suitable for small space or small server room;
2. Gemini series integrated modular unit: especially suitable for modern high-rise buildings and communication base stations;
3. Leonardo Renaldo series: suitable for a variety of medium- and large-scale constant temperature and humidity precision environments, such as the computer room, the overall computer room, the programmable control switching room and so on.
What is precision air conditioning? What is special air conditioning? Precision air conditioning is a special air conditioning?
Hello Precision air conditioning is a special air conditioning designed for modern electronic equipment room, its work precision and reliability are much higher than ordinary air power. For example, computer equipment and program-controlled switching products, composed of a large number of dense electronic components. To improve the stability and reliability of the use of these devices, it is necessary to strictly control the temperature and humidity of the environment in a specific range. Precision air conditioning can control the temperature and relative humidity of the computer room to within plus or minus 1 degree Celsius and 5%, thus greatly improving the life and reliability of the equipment.
What is the difference between precision air conditioning and civilian air conditioning
The rapid changes in technology and the rise of modern information technology have made the modern electronic equipment room increasingly popular. And the application of numerous modern electronic components, the server room environment has also put forward unprecedented high requirements. Thus, the application of air conditioning in the machine room is essential, it plays an indispensable role in the machine room.
In most people's view, we apply the precision air conditioning in the cooling is not worse than the special air conditioning, and price advantage, so the civil air conditioning wrongly applied in the computer room environment. Do not know, civil air-conditioning design to people-oriented, computer room special air-conditioning design to the electronic components based on the value of the two in the application and the specific technical details of the design of a number of differences.
Civilian air conditioning is not equivalent to precision air conditioning
First, the application of different objects. Precision special air conditioning is for the equipment room to provide constant temperature and humidity of the operating environment, and civilian air conditioning are directly serving people. Their design concepts and functions are completely different. The biggest difference in the design concept is that the special air conditioner for machine room is large air volume, small enthalpy difference and high sensible heat ratio, while the civil air conditioner is just the opposite, which is small air volume, large enthalpy difference and low sensible heat ratio. The concept of sensible heat ratio refers to the ratio of the cooling capacity of the air conditioner to the cooling capacity of the two types of dehumidification. Usually, the total cooling capacity of an air conditioner has two parts, one part is used for cooling, called sensible heat cooling capacity, and the other part is used for dehumidification, called latent heat cooling capacity. When a residential air conditioner is applied, more than 60% of the cooling capacity is used for cooling, and the remaining 30% is used for dehumidification. Civilian air conditioners have to dehumidify in order to ensure low noise, low airflow and comfort. The sensible heat ratio of air conditioners specialized for machine rooms will be 0.9 or above. One of the reasons why civilian air conditioners are not suitable for use in computer rooms is that there is no source of humidity in computer rooms, on the one hand, because computer rooms are well sealed, and on the other hand, computer room equipment does not emit water vapor like a human being, and human beings will produce water vapor through breathing and evaporation of sweat through the skin.
The second difference is that the air volume of precision air conditioning will be very large. For example, we in the IDC server room air circulation will reach about 30 times, that is, every two minutes to the server room air treatment once. The airflow of a residential air conditioner, on the other hand, will be very small. This is because the high heat of the server room requires a large air volume to circulate, similar to the small air volume of civil air conditioning, and the high heat of the equipment cannot be taken away by the rapid circulation of the air speed. Civilian air conditioning of small air volume and noise design is to consider the comfort of people.
The third difference, precision special air conditioning out of the wind temperature than civilian air conditioning. The high outgoing air temperature of the special air conditioner for machine rooms can avoid condensation, while the low outgoing air temperature of civilian air conditioners can sometimes cause condensation on the equipment, jeopardizing the normal operation of the equipment. In addition, civilian air conditioning has no humidification function can only dehumidify, but the special air conditioning can be based on the specific needs of the room to give appropriate humidification.
The fourth point is the difference between high precision. Because of the different technical means of control, the special air conditioning temperature and humidity control of the server room can reach ± 1 ℃, ± 1% RH of high precision, as well as a higher degree of cleanliness. In the northern region can be suitable for a variety of low-temperature operation, more than 30 degrees below zero, can still be normal through a number of options for the computer room cooling temperature control. The characteristics of the machine room in winter, summer, there is no essential difference, winter machine room also need refrigeration. Civilian air conditioning in the minus 30 degrees Celsius environment is basically no way to achieve normal work.
The core of dedicated precision air conditioning lies in the full protection of key services
Wang Tiewang, manager of the air conditioning system department of Emerson Network Power, said: The greatest value that dedicated precision air conditioning can bring to users is to protect the objective requirements of the main equipment and the operating environment. The purpose of meeting the requirements is to reduce the power consumption rate of the main equipment, reduce the failure rate of the main equipment, and reduce the total cost of the user in the operation cycle. This is essentially different from the simple temperature control function of civil air conditioning.
Based on the core value of precision air conditioning to protect the main equipment, which is different from civilian air conditioning, Emerson's dedicated server room air conditioners are designed to reflect the details of high stability, high energy-efficiency, economic operation, maintenance, high adaptability, and powerful expansion and heating functions. The core of the project is to utilize Emerson's advanced product technology and management experience to ensure the stable operation of client-side products, the normal operation of client-side core services, and the continuous improvement of client-side business operation efficiency, providing comprehensive protection for users' key businesses.
First, the precision air conditioner is more stable and has a longer lifespan. Take Emerson's small server room dedicated air conditioner DataMate3000 as an example, it can provide 24 hours, 365 days, more than 10 years of uninterrupted, continuous operation. And the people ...... >>

Precision air conditioning is what it means? What is its main operating principle? What are the advantages and disadvantages?
Precision air conditioning, can also be seen as a special air conditioning room, with constant temperature and humidity, and 24 hours a day all year round, so the life of the air conditioning than the family life, but the price can be imagined. Precision air conditioning air volume, enthalpy difference is small, which is also a main feature of precision air conditioning! The principle of work with the family applicable air conditioning floating the same, also with Freon refrigeration, but the precision air conditioning compressor is in the inside, unlike the family applicable air conditioning compressor in the outside!
There is also a purification air conditioning in the hospital operating room, we use the air conditioning is probably divided into these three categories
Hope to adopt, purely hand-written, a little bit of hard work fee, huh
What is called industrial-grade professional air conditioning? The first thing you need to do is to get your hands on a new one, and you'll be able to do that. I'm not sure if you're going to be able to do that.
Industrial grade air conditioning control environment temperature humidity accuracy is not as high as precision air conditioning, industrial grade sense of the air conditioning environment.
Industrial air conditioners have Daikin, precision air conditioners have Emerson, stulz, APC, RC and so on.
