區域冷暖房（DHC）供應系統技術簡介
District Heating and Cooling (DHC) Supply System Technology
摘要
區域冷暖房（DHC）供應系統是藉由區域能源整合利用及維持冷暖氣系統高效率運轉，以顯著提升整體能源效率。相較傳統各別獨立系統，可提升整體能源效率達25％～35％，減少54％的CO2排放，此外，亦可減緩城市熱島效應（heat island effect）等。在國外已有超過40年的應用並有非常成功的案例，於2006年，僅在日本就有超過150套DHC系統及84家合格營運公司，其中，超過74％的DHC系統皆以燃燒天然氣及電力為主要的動力源，所產生的冰水、熱水或蒸汽主要以供給當地的飯店與商業大樓等。韓國與日本為了鼓勵業者建置DHC，所有DHC系統使用之天然氣價格分別僅為市價之39％與55％，以創造建置與使用之誘因。推動DHC的成功關鍵因素是需有完善之法規及其配套措施，例如，日本的「熱供給事業法」規定，新建物樓板面積超過10,000平方米者，其空調系統必須採用DHC系統，用以達成整體節能減碳的目的。

District heating and cooling system has significantly to improve overall energy efficiency by through regional energy integration and to maintain high efficiency of heating and cooling systems. Comparing with the individual cooling or heating system, DHC may increase 25%~35% overall energy efficiency, decrease 54% CO2 emission and reduce city's heat island effect. There are brilliant systems for over 40 years in the foreign areas. In 2006, there are 150 DHC systems and 84 qualified companies in Japan. 75% of the qualified DHC systems use nature gas and electric power as the energy source. They supply ice water, hot water or steam to the local restaurants and commercial buildings. In order to encourage the industries to establish DHC systems in Korea and Japan, all DHC systems use gas prices as the market price of 39% and 55% to create incentives to build and use. Promote the DHC key success factors were the need to improve the regulations and its supporting measures. For example, Japan's ”Heat Supply Business Act” stipulates that new floor area of more than 10,000 square meters, air conditioning systems must be in DHC system, to reach an overall objective of energy saving and carbon reduction.
