STELF 기술의 핵심의 되는 IMPEX 블록의 잔류 공급률, 겉보기 밀도, 흑연의 혼합비 등 여러 가지 주요 변수가 블록의 특성에 미치는 영향을 조사하여 실제 반응기를 설계하는데 필요한 자료를 구하였다. 대표적인 염들에 대하여 물질전달 및 열전달 문제를 일으키지 않는 영역에서 최소의 부피를 갖는 값들을 계산하였고, 각각의 물질이 갖는 특정 전도도에서의 최대 냉방 및 난방 에너지 밀도를 계산하였다. 이로부터 얻은 값들을 8시간 동안 사용할 수 있는 6kW 냉방용 반응기 설계에 적용하여 본 결과 SrCL2-8/1 NH3가 최적의 염임을 확인하였다.

In this study the reactor design procedure and method of solid-solid-gas chemical heat pump system using STELF technology were investigated. For manufacturing IMPEX block which is the kernel of reactor, proper salt pair should be selected, and equilibrium temperature drop and COP should be examined for selected salt pair. Moreover, apparent density, residual porosity, and graphite ratio should be calculated to give minimum block volume and mass, and maximum energy density without causing heat and mass transfer problems. Since heat exchange area can be changed with operating condition, reactor diameter, length, and stainless steel thickness should be decided for desired specifications. These procedure and method were applied to the case study of 6kW cold production and 8 hours storage capacity reactor.

AN EXTENSIVE RESEARCH AND DEVELOPMENT WORK WILL BE CARRIED OUT FOR THE COMMERCIALIZATION OF THE CHEMICAL HEAT PUMP SYSTEM WHICH BASED ON THE ELF AQUITAINE FRANCE PATENTED AND KIME LICENSED SOLID/GAS CHEMICAL REACTION TECHNOLOGY. TOWARD ON THAT GOAL, THE BASIC AND ENGINEERING DETAILS SUCH AS IMPEX BLOCK MATERIAL, PHYSICO-CHEMICAL AND THERMO-CHEMICAL CHARACTERISTICS OF REACTION MECHANISMS IN THE SOLID/GAS CHEMICAL REACTION HEAT PUMP SYSTEMS. THREE KIND OF APPLICATION SYSTEM ARE NOW INVESTIGATED; AIR CONDITIONING, REFRIGERATOR AND INDUSTRIAL PROCESS HEATING AND COOLING SYSTEM.
