Czech-Chinese Project Transmission Enhancement and Energy Optimised Integration of Heat Exchangers in Petrochemical Industry Waste Heat Utilisation is a joint project of Czech Republic, SPIL, Brno University of Technology – VUT Brno and the People‘s Republic of China, Xi’an Jiaotong University, Xi’an, Shaanxi. The 3 y project contributes to solving the energy situation and reduction of emissions. The use of low-grade heat is an effective means of saving energy and reducing greenhouse gases, which is increasingly sought after both for large companies also in local industrial facilities and even households. It has been increasing the emphasis on the use of low-potential energy results in increased demand for sophisticated heat exchangers. Methods, standards and the creation of modular structures optimised for different outputs based on the practical use of research results are being developed for various sources of waste heat, types of circulating media and technical operating parameters. Layout and construction designs allow designers to professionally design and manufacture suitable heat exchangers for specific conditions of the production process from the very beginning and a wide scope of conditions and requirements. Utility models and software modules were created and supported with research publications.
