Research on Energy-saving Optimization of Air Conditioning Systems in Office Buildings in Hot Summer and Warm Winter Areas
With the rapid development of social economy,the number and energy consumption of office buildings are increasing day by day.In order to alleviate the current situation of energy shortage,the en-ergy-saving transformation of existing office buildings has become one of the important means to save en-ergy consumption and reduce carbon emissions.For areas with hot summer and warm winter,the energy consumption of office buildings is mainly refrigeration by air conditioning system.Based on the original air conditioning system of an office building in Shenzhen,this paper proposes two energy-saving optimi-zation schemes based on the main equipment of the air conditioning system,namely,magnetic levitation unit+variable frequency chilled water system,variable flow unit+variable frequency variable flow system.The two optimization schemes were compared and analyzed by Trnsys software.The results show that the energy consumption of the air-conditioning system can be reduced to a certain extent by chan-ging the equipment energy and adopting frequency conversion technology,and the COP of the system can be greatly improved.
