In today's increasingly serious data center energy consumption problem, the refrigeration system is undoubtedly the key to energy saving (the energy consumption of the refrigeration system accounts for 40-50% of the total energy consumption of the data center). At present, the energy-saving technologies of refrigeration systems commonly used in the industry include fresh air energy-saving systems and ethylene glycol energy-saving systems. However, these technologies also have certain disadvantages. For example, the fresh air system will reduce the cleanliness of the computer room, and the glycol energy-saving system has complicated installation, large footprint, and high investment. In response to these problems, Emerson Network Energy Co., Ltd. began to develop intelligent energy-saving dual-cycle air conditioning products in 2005. After four years of development and a large number of experiments, it was officially released in 2009 and applied for patent protection. The system is efficient, energy-saving, and environmentally friendly. It is a revolutionary innovation in the computer room refrigeration industry and will become a model for energy-saving innovation in the computer room refrigeration industry.

Energy saving principle

The SDC intelligent energy-saving dual-cycle unit adopts a modular design idea, adding an energy-saving refrigeration cycle module to the same set of units. When the outdoor temperature reaches the switching point, the compressor refrigeration system is stopped and the energy-saving refrigeration cycle is turned on. Outdoor low temperature cooling refrigerant. Send the refrigerant to the indoor unit to achieve the purpose of energy-saving cooling. The unit can also intelligently adjust the switching and configuration of the two refrigeration systems according to indoor load and outdoor temperature to ensure that the unit maintains the maximum energy-saving operating state under any circumstances.

System Features:

High reliability, high flexibility, low cost throughout life;

Intelligent switching between conventional refrigeration cycle and energy-saving refrigeration cycle. Taking 90kW cooling capacity and dual compressor units as an example, the energy saving rate can reach 70% during energy-saving refrigeration operation;

Do not directly introduce fresh air, maintain the airtightness of the machine room, and achieve precise control of temperature, humidity, and cleanliness;

Without adding independent operation equipment, the conventional system and the energy-saving system can be operated in a set of units to save space;

Removable handling structure, 100% full frontal maintenance; conventional units can be transformed into energy-saving units;

Emerson Copeland high-efficiency scroll compressor, suitable for environmentally friendly refrigerants;

Unique high-efficiency far-infrared humidification system, fast humidification speed, adapt to poor water quality, low maintenance;

Air-cooled full-speed condenser, low noise and low power consumption;

Large screen full Chinese graphic display;

Provide standard RS485 interface to realize remote monitoring.

energy saving effect

Taking the 90kW cooling capacity and dual compressor SDC unit as an example, the energy saving amount and energy saving rate are calculated relative to the traditional air conditioner in the traditional computer room. The data shows that the energy saving rate of SDC intelligent energy-saving dual-cycle air conditioners in most parts of northern China is more than 20%, especially in the northeast, north and northwest regions, and the energy saving is very considerable. For example, the average energy saving rate in Harbin is 34%, the annual energy saving is 32,000 kWh, and carbon emissions are reduced by 31.8 tons.

In 2009, Emerson SDC intelligent energy-saving dual-cycle air conditioner was successfully applied in Inner Mongolia Bayannur Mobile Company. The actual energy saving rate test data shows that when the outdoor temperature is -1 ℃, the energy saving rate exceeds 40%.

Application range

SDC units use outdoor natural cooling sources to achieve energy saving. The lower the temperature and the longer the duration, the better the energy saving effect. For the central and northern regions of China, especially the northeastern, northern and northwestern regions of China, as well as the regions with long periods of low temperatures throughout the year are the main areas of use, and due to the large-capacity air conditioner, the energy saving effect will be better and the return rate will be higher. Therefore, it is more suitable for medium / large data computer rooms, computer rooms and data centers, industrial control rooms and laboratories and other places with medium and large air conditioning.

Lying in the sofa and enjoying a movie with family is the happiest thing in life! We offer you one more reason to enjoy, because we create the most comfortable living room for you.

One full set of living room usually consists of sofas set (Fabric Sofa or Leather Sofa), wall units, hanging shelves, or TV stand, center Coffee Table, side Coffee Tables or End Tables .
