  • This paper provides a fusion technology between a district cooling energy system and an environment conservation policy based on the energy savings and reusable cold energy resources. The district heating and cooling systems are very effective ways for an energy saving, a cost reduction and a safety control. It is necessary to equalize the energy savings and an environmental preservation policy for an improved human lift. A gasification process of a liquefied natural gas, cooling water from deep seawater and an ice water thermal storage system may produce a cold energy. A district cooling system is used to cool an apartment, office buildings and factory facilities with a cooling energy supply pipeline. LNG cooling energy will switch a conventional air-conditioning system, which is operated by on electrical energy and a Freon refrigerant. Coincident with significant clean energy and operating cost savings, LNG cold energy system owen radical reductions in an air-borne pollutant, $CO_2$ and the release of environmentally harmful refrigerants compared with that of the conventional air-conditioning system. This study provides useful information on the fusion technology of a LNG cold energy usage and energy savings, and environmental conservation.

  • The district heating system has been successfully implemented with higher efficiency levels of energy production and reduction of carbon emissions during heat generation. Traditionally the system consisted of small number of production and demand sites, but, recently it has evolved into a network with large number of sites interconnected each other. By connecting multiple sites into a network, heat from low-cost production sites can be supplied to distant demand sites so as to lower the total operation cost. In this study, we simulate and analyze distict heating networks focused on critical links. a critical link is defined as a link in which capacity is fully utilized. If a newtork has critical links, then those cricial links become bottlenecks and it is difficult to improve the overall network efficiency.

  • As GHG reduction becomes a major global issue, the importance and interest of ETS is increasing. Korea experienced positive effects of the system since the introduction of ETS in 2015, but also faced various problems. The focus of this study is on the issue of applying the ETS system to the group energy of industrial complexes. The group energy of industrial complexes is a unique industrial form of Korea that cannot be found in the world. Therefore, if the system is implemented in the same way as the preceding countries, it will inevitably cause problems. In particular, the group energy of industrial complexes has the characteristic that the conditions and amount of heat supplied are dtermined according to the demands of customers and the amount of power generation is determined accordingly. We investigated how differenct temperatures of heat produced in cogeneration affect carbon credit calculations.
