Design practice of energy saving and carbon reduction renovation of air conditioning system for a dispatch communication building

This paper focuses on the energy saving and carbon reduction renovation design of the air conditioning system for a dispatch communication building. Through the comprehensive use of waste heat recovery, renewable energy, solid heat storage, high efficiency refrigeration room and other technologies, a safe, reliable, green, low-carbon, high efficiency and energy saving air conditioning system is constructed. The HDY-SMAD air conditioning load calculation and analysis software is used to simulate the annual air conditioning energy consumption of the building, and the operation energy consumption and the carbon emission of the air conditioning system before and after optimization are calculated. The results show that the optimized air conditioning system saves 1 million kW·h of electricity and reduces 573 t of carbon emission in the whole year, and the effect of energy saving and carbon reduction is remarkable.
