Abstract

The central air-conditioning system which runs under the mode of fresh air mixed with return air doesn´t take full advantage of the fresh air to remove air conditioning load, leading to high energy consumption and carbon emission. The calculation model for carbon emission reduction of all-fresh air operation in central air-conditioning system is proposed based on the air conditioning control strategies of thermal comfort and the qualification of constant air volume. It also consulted local meteorological condition, historical data of energy consumption of the system and coefficient of carbon emission. The study takes a commercial mall in Chongqing as the case to test the model.
