Industrial low temperature waste heat exists sparse in surroundings but its amount is huge. However, large portion of waste heat is discarded due to its poor recovery quality and inferior application technologies. The heat pump system in this research is based on the hybrid combination of compression cycle and absorption cycle in order to recycle various kind of industrial waste heat effectively. The prime objective is to design a compression absorption hybrid heat pump system which can produce high temperature above the level of 90°C and low temperature of 20°C at the same time using waste heat water of 50°C. A mathematical simulation was carried out as a basis to design a prototype 3 RT class hybrid heat pump. From the simulation results, fundamental parameters to design the system were obtained.
The Purpose of this study is to compare between domestic and international codes and its components about architectural environmental areas and establish contents of Korean Building Code-Environment, Energy saving, Mechanical and Electrical equipment(KBC-EEME), and propose its future directions. First of all, domestic and international codes about architectural environmental areas were compared and analyzed. Domestic code of architectural environmental areas was enacted by a variety of government ministries while all of the international codes investigated in this study were enacted by a single organization. Thus, in this study, all of the Korean codes about architectural environmental areas were integrated under the KBC-EEME table. Furthermore, some contradicted contents in domestic code were founded due to many different government ministries, so the necessity of a single organization for domestic code was suggested. Finally, some contents of international codes which were inadequate in domestic code were offered for the future KBC-EEME, and the future work for globalization of the KBC-EEME was raised.
