Project Name: Shenzhen Book City Computer Room Energy Saving and Efficiency Improvement Project

Project Location: No. 5033, Shennan East Road, Luohu District, Shenzhen City, Guangdong Province

Construction unit: Shenzhen Publishing Group

Building scale: The air-conditioned area is about 200,000 ㎡.

Refrigeration machine room: 2 sets of refrigerating mainframes with a total of 500RT, using 4-12° water cooling system, cold storage supply and return water temperature 4-12°C, freezing supply and return water temperature low temperature: 7-12°C, using the original fire pool to achieve cold storage and It is also used for fire fighting, and at the same time, the original main engine, water pump, pipeline, etc. are replaced and redesigned. The effective volume of cold storage is 900m³, 1 cold storage tank, 550mm inclined temperature layer, 92% cold storage efficiency, and the maximum cold storage and discharge capacity is 2200RTH. The overall system adopts a direct storage and indirect discharge system structure.

Quality and efficiency: The project was successfully accepted and highly praised, with stable operation and good economic and social benefits.
