Practicability analysis of using natural cold source for cooling an IDC plant

Based on the application status of air conditioning energy saving technologies in telecommunication industry, analyses the energy saving renovation of air conditioning in an IDC plant in Langfang, Hebei Province. The analysing and comparing results of directly introducing fresh air system and isolated fresh air exchanging system indicate that using outdoor fresh air for cooling the plant is practicable according to its air conditioning load characteristics and outdoor climatic conditions. Economic analysis results show that using natural cold source can reduce the operation energy consumption of air conditioning, realizing electric power reduced over 30% with recovery period less than 2.5 years, which has favorable economic and social benefits.
