I will answer your questions one by one.

What is the function of precision air conditioning in the computer room?

Precision air conditioning in the computer room can provide a constant temperature and humidity environment for the computer room. In many important jobs, information processing is an indispensable link. Therefore, the normal operation of the company can not be separated from the constant temperature and humidity reference room. IT hardware will produce unusual concentrated heat load and is also very sensitive to changes in temperature or humidity. The fluctuation of temperature or humidity may lead to some problems, such as garbled codes in the treatment process, and even cause the system to stop running completely in serious cases. This will bring huge losses to the company, depending on the system downtime and the value of lost data and time. The standard comfort air conditioner is not designed to deal with the heat load concentration and heat load composition of the data room, nor to provide accurate temperature and humidity settings for these applications. Precision air conditioning system is designed for precise temperature and humidity control. Precision air conditioning system has high reliability, continuous operation throughout the year, maintainability, assembly flexibility and redundancy, which can ensure the normal operation of air conditioning in data room in all seasons. Schneider Uni special air conditioner can fully meet the various needs of users:

1.AMICO series and Neptune series: suitable for narrow space or small computer room;

2. Gemini series integrated modular units: especially suitable for modern high-rise buildings and communication base stations;

3. Leonardo Lei Natuo series: suitable for all kinds of medium and large precision environments with constant temperature and humidity, such as the whole computer room and program-controlled switchboard room.

What is precision air conditioning? What is a special air conditioner? Is precision air conditioning a special air conditioner?

Hello precision air conditioning is a special air conditioner specially designed for modern electronic equipment room, and its working accuracy and reliability are much higher than ordinary aerodynamics. It has strong wind power, such as computer equipment and program-controlled switch products, and is composed of a large number of dense electronic components. In order to improve the stability and reliability of these devices, it is necessary to strictly control the temperature and humidity of the environment within a specific range. Precision air conditioning can control the temperature and relative humidity of the computer room within plus or minus 65438 0 degrees Celsius and 5%, thus greatly improving the service life and reliability of the equipment.

What's the difference between precision air conditioning and civil air conditioning?

With the rapid development of science and technology and the rise of modern information technology, modern electronic equipment rooms are becoming more and more popular. The application of many modern electronic components has put forward unprecedented high requirements for the computer room environment. Therefore, the application of air conditioning in the computer room is essential, and it plays an indispensable role in the computer room.

In the eyes of most people, the precision air conditioning we use is not worse than the special air conditioner in refrigeration, and it also has an advantage in price. Therefore, the application of civil air conditioning in computer room environment is wrong. As we all know, the design of civil air conditioning is people-oriented, and the design of special air conditioning for computer room is based on electronic components. There are many differences between them in application value and specific technical details.

Civil air conditioning is different from precision special air conditioning.

First of all, the applicants are different. Precision special air conditioning provides a constant temperature and humidity environment for the equipment in the computer room, while civil air conditioning serves people directly. Their design concepts and functions are completely different. The biggest difference in design concept is that the special air conditioner for computer room has large air volume, small enthalpy difference and high sensible heat ratio; Civil air conditioning is just the opposite, with small air volume, large enthalpy difference and low sensible heat ratio. The concept of sensible heat ratio refers to the relative ratio of refrigeration capacity and dehumidification capacity of air conditioning. Usually, the total refrigeration capacity of an air conditioner has two parts, one is used for refrigeration, which is called sensible heat refrigeration capacity, and the other is used for dehumidification, which is called latent heat refrigeration capacity. When using civil air conditioning, more than 60% of the cooling capacity is decreasing, and the remaining 30% is dehumidifying. In order to ensure low noise, low air volume and comfort, civil air conditioners have to be dehumidified. The sensible heat ratio of the special air conditioner in the computer room will be above 0.9. One of the reasons why civil air conditioners are not suitable for use in computer rooms is that there is no moisture source in the computer rooms. On the one hand, it is because the computer room is well sealed. On the other hand, the equipment in the computer room does not emit water vapor like people, but people produce water vapor through breathing and skin evaporation.

The second difference is that it will be windy in precision air conditioning. For example, we will circulate the air in the IDC computer room for about 30 times, that is, we will treat the air in the computer room every two minutes. The air volume of civil air conditioners will be very small. This is because the high heat in the computer room requires large air circulation, which is similar to the small air volume of civil air conditioners. The high heat of the equipment cannot be taken away by the rapid circulating wind speed. The design of small air volume and low noise of civil air conditioning is based on the consideration of human comfort.

The third difference is that the outlet temperature of precision special air conditioner is higher than that of civil air conditioner. The higher air temperature of special air conditioner in computer room can avoid dew condensation, while the lower air temperature of civil air conditioner sometimes causes dew condensation on the equipment, endangering the normal operation of the equipment. In addition, civil air conditioners can only dehumidify and have no humidification function, but special air conditioners can be appropriately humidified according to the specific needs of the computer room.

The fourth point is the difference between high precision. Due to the different technical control methods, the temperature and humidity control of the special air conditioner in the machine room can reach the high precision and higher cleanliness of 1℃ and 1% RH. In the northern region, it can be suitable for all kinds of low-temperature operation. In the case of MINUS 30 degrees, the temperature of the computer room can still be controlled normally through some options. There is no essential difference between the characteristics of the computer room in winter and summer, and the computer room in winter also needs refrigeration. However, civil air conditioners can hardly work normally in the environment of MINUS 30 degrees Celsius.

The core of precision special air conditioning lies in the full guarantee of key business.

Wang, manager of Emerson's network energy and air conditioning system department, said: the greatest value that precision special air conditioners can bring to users is to ensure the objective requirements of the main equipment and operating environment. The purpose of meeting the requirements is to reduce the power consumption rate of main equipment, reduce the failure rate of main equipment and reduce the total cost of users in the operation cycle. This is essentially different from the simple temperature control function of civil air conditioners.

Focusing on the core value of precision special air conditioner to protect the main equipment, which is different from civil air conditioner, the design of Emerson's special air conditioner for computer room embodies details such as high stability, high energy efficiency, economic operation, maintainability, high adaptability, powerful expansion and heating function. Its core is to use Emerson's advanced product technology and management experience, with the help of a powerful platform, to ensure the stable operation of customer-side products, the normal operation of customer-side core business and the continuous improvement of customer-side business operation efficiency, and to provide users with all-round services.

First of all, the precision special air conditioner has stronger stability and longer service life. Take Emerson DataMate3000 as an example, it can provide uninterrupted continuous operation for 24 hours, 365 days and more than 10 years. And the people ... >>

Where is precision air conditioning mainly used? Five points.

Telecommunications, finance, medical treatment, laboratory, electronic instrument assembly plant, precision machinery, measuring room, base station, thermostatic chamber and other industries or places.

What does precision air conditioning mean? What is its main working principle? What are the advantages and disadvantages?

Precision air conditioning, which can also be regarded as a special air conditioner for computer room, has the function of constant temperature and humidity. It can be turned on 24 hours, and its service life is longer than that of household air conditioners, but the price can be imagined. Precision air conditioning has a large air volume and a small enthalpy difference, which is also a major feature of precision air conditioning! The working principle is the same as that of the household air conditioner, but this precision air conditioning compressor is inside, unlike the household air conditioner compressor outside!

Hospital operating rooms also have clean air conditioners, and the air conditioners we use can be roughly divided into these three categories.

I hope to adopt. This is handwritten. A little hard, hehe.

What is industrial professional air conditioning? Is it the same concept as precision air conditioning? What brands are there?

The temperature and humidity accuracy of industrial air-conditioning control environment is not as high as that of precision air conditioning, so it is an industrial air-conditioning environment.

Industrial air conditioners include Daikin, Emerson, stulz, APC and RC in precision air conditioning.
