1. High-precision constant temperature and humidity air conditioners meet the cleanliness requirements of the computer room.
    In high-precision constant temperature and humidity air conditioners, air filters that meet the above standards are installed, strictly designed according to 0.5 microns/liter <18,000 (Class B), and 30 air volume cycles per hour to ensure the cleanliness of the computer room. This filter device can fully meet the requirements of the computer room for air cleanliness. What is more practical is that this filter device is directly installed in the precision air conditioner and does not need to occupy any additional space. It is also very convenient to clean and replace. Comfort air conditioners only have simple filtering functions and do not provide filter spare parts. Generally, they have no filtering function after 1-2 months of use.
2. High-precision constant temperature and humidity air conditioner has a unique air supply method.
    The design concept of precision air conditioner is to make the equipment work in a high-quality environment. In addition to the air supply organization method of upper delivery and side return of the usual air conditioner, high-precision constant temperature and humidity air conditioner also chooses the air supply organization method of upper delivery and lower return and lower delivery and upper return. This method places the precision air conditioner rack on the anti-static movable floor, and uses the space under the floor as the air supply static pressure box. According to the principle of consistent static pressure, the uniformity of the air supply airflow is increased. This method also allows the cold air sent by the precision air conditioner to directly cool the electronic equipment in the programmable rack from bottom to top. Then it returns to the upper return air outlet of the air conditioner, so that it can fully cool the electronic equipment and play the maximum efficiency for normal operation.
3. High-precision constant temperature and humidity air conditioner outlet temperature is suitable for
    precision air conditioner. In the design of outlet temperature, it avoids the "dew point problem" and solves the overall cooling problem of the computer room through the design of large air volume (the minimum ventilation frequency is designed to be 30 times, that is, the air in the computer room is effectively filtered once every 2 minutes).
4. High-precision constant temperature and humidity air conditioners can operate normally below -5℃.
    The design of precision air conditioners strictly adapts to the requirements of various outdoor temperature changes. The air conditioner can operate normally 24 hours a day between -40℃ and +45℃, including cooling and heating.
5. High-precision constant temperature and humidity
    air conditioner temperature adjustment accuracy. The temperature adjustment accuracy of high-precision air conditioners is 1℃. The sensing point is the entire machine room, and the temperature does not fluctuate.
6. High-precision constant temperature and humidity air conditioners have a long design life.
    The design life of precision air conditioners is 10 years, and the operation requirement is 365 days a year, 24 hours a day.
7. High-precision constant temperature and humidity air conditioners have low maintenance costs.
    The design of precision air conditioners is aimed at "maintenance-free". The control system uses a highly intelligent microprocessor control device with fast response speed, high precision and good reliability. Its maintenance volume is only concentrated on simple tasks such as filter replacement and humidification tank cleaning automatically prompted by the unit, without the need for a professional maintenance team. Maintenance departments tend to use precision air conditioners.
8. High-precision constant temperature and humidity air conditioning can realize network management.
    High-precision constant temperature and humidity air conditioning system conforms to the trend of the times and develops highly practical networking software. It can connect the air conditioners distributed in different rooms and floors in the building and the air conditioners distributed in various areas of the city through twisted shielded pair cables, telephone networks and modems, and implement centralized monitoring. Usually, the output of the computer is a digital signal, which is converted into an analog signal through a modem and transmitted through a public telephone network. A modem is also required in the remote site to convert the analog signal into a digital signal to achieve communication. Its main feature is that it uses a vivid chart system for display and operation, which is simple and easy to operate, making the system and user contact interface very harmonious. The alarms occurring in each site are actively connected and reported to the central computer, and it has an automatic printing function. Through networking, the management and control level can be improved and some problems can be discovered in time.
9. High-precision constant temperature and humidity air conditioning energy efficiency The energy efficiency
    ratio (EER) is the ratio of the amount of cooling (heating) obtained to the energy paid, including the power consumed by the system fan. The high-precision constant temperature and humidity air conditioner adopts industrial standards, with an energy efficiency ratio of up to 3.4, while the energy efficiency ratio of the comfort air conditioner is 2.9.
