Abstract: According to research, the annual energy efficiency ratio of air conditioning and refrigeration
rooms in most public buildings in China is only 2.0-3.0, which is a low energy efficiency level. With the
issuance of the Implementation Plan for Carbon Peaking in Urban and Rural Construction (JB No. 53)
by the Ministry of Housing and Urban-Rural Development and the National Development and Reform
Commission, it is clearly proposed to strengthen the operation and debugging of key energy consuming
equipment such as air conditioning, improve equipment energy efficiency, and achieve a 10% increase
in the overall energy efficiency of public building electromechanical systems by 2030. How to build and
operate efficient air conditioning and refrigeration rooms has become a hot research topic. Using a
combination of theoretical research, IT development, and demonstration applications, the technology
related to the construction of efficient air conditioning and refrigeration rooms was studied. Through
project demonstration applications, the annual energy efficiency ratio of the demonstration project's air
conditioning and refrigeration room system was increased to 5.32, meeting the 3-level energy efficiency requirements specified in the current group standard Technical Specification for High Efficiency Refrigeration Room (T/CECS 1012-2022). The results show that this technology can significantly improve
the energy efficiency level of air conditioning and refrigeration room operation and should be further
promoted in the future step by step.
