Exploring the vast universe, developing the space industry, and building a strong space nation are our relentless pursuit of space dreams.
The development of China ’s space industry in recent years is obvious to all. The Long March series of rockets, the Beidou satellite lift-off, and the Chang'e lunar exploration project all indicate that China has made great progress in the space field.
The Space Application Engineering and Technology Center of the Chinese Academy of Sciences, on behalf of the Chinese Academy of Sciences, is responsible for the planning and implementation of manned space science and application missions, as well as the output and promotion of results.
The center organizes many research institutes across the country to carry out space science and applied research, and has achieved a large number of valuable science and technology in the fields of earth observation and earth environment monitoring, space life science and biotechnology, space material science, space astronomy and environmental exploration. Application results. These achievements are inseparable from the hard work and efforts of researchers.
In order to provide a more comfortable environment for scientific researchers, the building finally adopted FLEXMULTI Series Hitachi inverter multi air conditioning system, FLEXMULTI family heritage of Hitachi air conditioning products, high-end technology and superior quality, application of large capacity and high efficiency scroll compressor and high-pressure chamber Advanced frequency conversion technology realizes the sublimation and performance breakthrough of multi-line technology .
The Chinese Academy of Sciences' Space Application Engineering and Technology Center has a total construction area of ​​41,822 square meters and a building height of 45 meters. As a workplace for senior managers and R & D talents, the entire building is distributed with a variety of scientific laboratories. It has brought challenges to the provision of central air conditioning solutions.
0 1 Challenge 1 System configuration meets diversity
The center is composed of the space application research building in the south building and the environment and professional experiment building in the north building. The two floors belong to different departments, with different needs, and there are many types of laboratory disciplines, and the use time varies greatly.
When designing the air conditioning indoor and outdoor unit capacity ratio and indoor unit capacity configuration, Hitachi engineers fully combined the use differences of the laboratories in each building to formulate a plan, which can not only meet the needs of heating and cooling comfort, but also reduce unnecessary energy consumption. ,Energy saving and environmental protection.

Challenge 2 System installation is restrictedThere are 11 floors in the central building, and the air-conditioning area is from 1 to 11. The outdoor units are concentrated on the roof of the building, with a maximum drop height of 40m and a maximum total piping length of 80m.
In order to make the pipeline installation meet the requirements, Hitachi engineers strictly carried out the construction according to the plan, and specially formulated several kinds of brackets and hangers according to the different installation locations, so as to ensure the maximum installation effect.
Because there are a large number of scientific laboratories in the building, such as electromagnetic compatibility laboratories, component laboratories, environmental laboratories, etc., and these laboratories use special air conditioning equipment, the pipes of the multi-online system cannot cross it.
To this end, Hitachi technicians made detailed reservations and pre-embedded drawings after various investigations and communications, so that no missing or wrong embeds were laid, which laid a good foundation for the next step of construction.

Challenge 3 fits with the decoration styleThe decoration grade of the center is relatively high, and the large area of ​​indoor ceiling adopts the form of ceiling of long aluminum buckle plate. In order to avoid destroying the original decoration, Hitachi engineers strictly implemented Hitachi air conditioning installation and operation procedures during construction, accurately positioned the locations of various air outlets and air outlets to ensure the effect of air conditioning, and at the same time carefully conducted inspection and acceptance of each concealed project .
When choosing the form of indoor unit, it also fully considers the function and interior decoration of the room to reflect the individualization and diversification while effectively ensuring the air supply effect and reducing noise.
In addition, in order to increase the air circulation and freshness of the work and activity areas, according to the specific needs of the room , the fresh air system uses a fresh air processor and a full heat exchanger to introduce fresh air and control the temperature within the comfortable range of the human body. Inside, it brings comfort and health to the scientific researchers of the center.
Since the air conditioning acceptance of the entire building was completed on April 15, 2017, Hitachi Central Air Conditioner has been operating steadily here for more than 2 years. The operation effect is very good, and the inspection data have fully met the design requirements.
On April 4, 2018, a sudden snowfall instantly lowered the highest outdoor temperature in Beijing from 26 ° C to 0 ° C. In order to ensure a comfortable working environment in the technical center, the central air conditioning system must be switched from standby to heating operation as soon as possible. Hitachi's multi-online system quickly starts heating, and its strong and stable operation has won the appreciation and trust of property management staff and center staff.
