1. The energy-saving potential of efficient computer rooms

The electricity consumption of air conditioning systems accounts for 40% -50% of the electricity consumption of public buildings, while the electricity consumption of refrigeration rooms accounts for 70% -80% of the total electricity consumption of central air conditioning systems. However, the energy efficiency of domestic refrigeration rooms is relatively low, so building efficient rooms is an indispensable part of reducing the overall energy consumption of public buildings.

2. What is an efficient computer room

The annual comprehensive energy efficiency ratio (EER) of the refrigeration room is usually used to measure the actual operation of the refrigeration room, and the EER value refers to the ratio of the total refrigeration capacity of the room to the total electricity consumption of the refrigeration room. Namely: EER=total cooling capacity/(chiller+chilled water pump+cooling water pump+cooling tower) power consumption. Currently, in the industry, air conditioning rooms with an EER>5.0 are generally referred to as high-efficiency air conditioning rooms.

4. The significance of efficient computer room

·Effectively reducing the operating costs of the data center (for the efficient data center completed by Zhongjing, the energy savings throughout the entire lifecycle are usually more than 10% to 40%).

·Due to the overall rational planning, unnecessary costs have been reduced, and the initial investment in Zhongjing's efficient data center is similar to or even lower than that of traditional data centers (some projects have higher initial investments than traditional data centers, but the investment return period is short).

·Meet the requirements of the national new infrastructure development strategy for supporting computer rooms (usually the newly constructed supporting computer rooms require efficient ones).

·Can effectively assist homeowners in applying for green and energy-efficient building and LEED, Green Mark certifications, etc., improving project quality; At the same time, it can also receive corresponding national energy-saving subsidies (reducing investment costs).
