Study on Energy Consumption Characteristics of Air Conditioning Cold Source in Public Buildingsand Carbon Reduction Effect of Collaborative Mode of Photovoltaic and Power Grid
Making full use of renewable energy is the key to realize building energy conservation and emission reduction, a-mong which building photovoltaic has attracted widespread attention. For public buildings in hot summer and warm winter areas, taking a library as an example, this paper establishes the TRNSYS simulation model of air conditioning cold source and rooftop pho-tovoltaic system, and simulate the energy consumption of cold source system and the power generation of photovoltaic system. The re-sults show that the running power demand of cold source system and photovoltaic power supply have a good match on typical days of air conditioning. During the operation period of air conditioning in summer, the self-sufficiency rate of building photovoltaic power generation for cold source system reaches 68％, and the carbon emission is reduced by 657.71 t/a. Building photovoltaic can be ef-fectively absorbed by air conditioning cold source, and the emission reduction effect is remarkable.
