요약1 본 연구에서는 에너지 절약적 공기조화기인 열펌프에 대한 특허 출원동향을 조사 분석하여 향후 열펌프 기술개발의 기초자료를 제공하고자 한다. 본 연구는 1983년부터 2002년 사이에 출원된 특허를 대상으로 하였으며, 이들 특허에 대하여 국가별, 형식별, 주요 출원인별로 기술흐름과 기술동향 및 기술분포 등을 분석하였다.
요약2 A technical analysis was conducted to predict the development trends for heat pump system. This study was based on submitted patents from 1983 to 2002 in Korea, USA, and Japan. The total number of raw data from the registered database was 19,261 and the obtained data to be analyzed through the filtering process was 5,143. Japan's technical development for the heat pump system was more dominant than the other countries. Approximately 54% of the total patents related with the heat pump system was registered by Japan. The number of patents for the heat pump system registered by Korea was very low in 1980's, but it increased rapidly in 1990's. As a result, the number of patents applied by Korea was 21% of all patents. When the patent was categorized into compression, absorption/adsorption, and chemical type, the technology of compression type made up over 80% in each country. Approximately 93% of the patents surveyed in this study was developed for air or water source heat pumps because of easy applications compared with other heat sources. The 89% of all patents was applied by companies when applicants were divided into three groups of company, individual, and the others(national institute, university, and so on).
