Research on Performance of Large Rotor-type Heat Recovery Exchanger using CFD Analysis on Surface Corrugation

ABSTRACT:The field of the large volume heat exchanger for wasted heat recovery ventilation system is being expanded enormously seeing as the fact that the quantity of reducing energies are huge due to the large volume heat exchanger for wasted heat recovery system at large buildings and factories, which consume large amount of energies while it has been arising huge amount of losses in Korea because of the lack of technology. To develop large volume waste heat recovery heat exchanger, rotor type heat exchanger was simulated for the surface corrugation. Based on the simulation results produced 30,000 ㎥/h grade waste heat recovery, heat exchanger was performed for the actual experiment. In addition, performance tests exceed the capacity of a large waste heat recovery heat exchanger performance test methods proposed.Keywords:Waste heat recovery(폐열회수), Temperature efficiency(온도교환 효율), Heat exchange efficiency(열교환 효율), Computational fluid dynamics(전산유체역학) †Corresponding author Tel.: +82-51-629-6178; fax: +82-51-629-6178 E-mail address: jskum@pknu.ac.kr
