This study aimed to investigate the dynamic simulation of a sorption thermal battery using water-lithium bromide as a working fluid. Sorption thermal battery assisted with solar power is a key technology for zero-energy buildings. During the charging period, thermal energy is stored in the form of chemical potential by sorption reaction, and it is released in the form of thermal energy during the discharging period. Because the solar energy varies with time and cooling load of the building is not in a steady state, the sorption thermal battery also does not operate in a steady state. In addition, it is difficult to accurately analyse the transition point from charging to discharging period and predict the heat duty and pressure variation of the evaporator/absorber when using only the steady state. Therefore, dynmaic modelling of the sorption thermal battery considering both transient and steady state performance is important. Also, there is no standard for setting the charging and discharging period of the thermal battery, so it is not possible to select the optimal operating time. The purpose of this study is to find the optimal thermal energy sotrage density and performance behaviours according to the time scale by introducing the non-dimensional arameters through the mass flow rate of the cooling water and solution. The final optimized energy storage density is estimated of 144.91 kJ/kg and COP is 0.64 at the optimized non-dimensional time constant.

A diffusion absorption refrigeration cycle (DAR) employs the bubble pump as the driving machine with the thermal energy input. As the bubble pump is critical in determining the performance and the operating characteristics of the DAR, the parameters which affect its efficiency are of major interest. In this study, the evaporation temperature was experimentally measured for each configuration of the bubble pump with different number of tubes. The objective of this study is to apply HFO series refrigerant as an alternative working fluid for the DAR. R1234ze(E) was selected as the alternative low GWP refrigerant while DMAC and helium were used as an absorbent and an auxiliary gas, respectively. During the experiments, the heat input was varied from 50W to 120W by electric heaters. The pressure was maintained at 600㎪, which is the saturation pressure of R1234ze(E) at around 30℃. It was found that the lowest evaporation temperature was measured as –10.2℃ at the condition in which two tubes were used and the given heat input was 70W. The diameter of each tube was 4.76㎜.

빠르게 변화하는 경영 환경 속에서 기업들은 변화에 대응하며 기업의 지속적인 성장을 위해서 프로세스 경영, ERP 등 기업의 업무 프로세스 혁신기법과 업무를 지원할 수 있는 IT시스템들을 도입하여 왔다. 하지만 통합적 관리 체계의 부재로 업무 프로세스와 IT간의 분리 현상이 발생하여 기업 경영의 효율이 저하되는 문제가 나타났다. 이러한 문제의 해결을 위해 BPM(Business Process Management) 개념이 대두되었고, 많은 기업들이 도입을 시도하고 있는 상황이다. 본 연구는 BPM 도입을 시도하고 있는 국내 건설기업을 대상으로 단위업무에 대한 IT시스템 지원도 평가를 통해서 BPM 도입의 주요 배경이 되는 업무 프로세스와 IT간의 분리현상에 대한 정량적 평가를 목적으로 하였다. 이를 위해 문헌 고찰과 사례 분석을 통해 평가의 필요성을 제시하고, 평가를 위해 건설기업의 본사업무를 중심으로 단위 업무를 계층화 하였으며, 업무지원 IT시스템을 분석하였다. 이를 토대로 평가 방법을 설계 하고, 평가 결과 분석을 통해서 건설기업의 BPM구현에 있어서의 시사점을 제시하였다. Many enterprises have adopted various management techniques and IT systems such as "Process Management", "ERP" for coping with rapid business environment change and for continual growth. However, the separation problem between business process and IT system which causes reduction of business management efficiency has occurred for the lack of integration management mechanism. To solve this problem, many companies try to adopt BPM (Business Process Management) concept. The purpose of this study is to identify this separation problem in Korean construction companies which are trying to apply BPM to their business through evaluating IT system support to business processes. This study indicated the need of evaluation through current researches and case studies, then made hierarchy of home business of construction companies and analyzed IT systems for supporting business. The evaluation method is designed based on these researches. This study proposed the implications for adopting BPM in construction companies based on evaluation results analysis.

In this study, a simulation study of thermal battery for cooling and heating in buildings using H2O-LiBr was conducted. With the assumption of well-conditioned external fluids, a mathematical model is established. The characteristics such as pressure, temperature, concentration, and power change of the thermal battery system during charging and discharging were investigated, and the performance of the thermal battery system was analyzed. As a result, it was found that the COPs of cooling and heating were 0.594 and 0.960, respectively. This demonstrates that the H₂O-LiBr thermal battery system can be an effective means for the storage of thermal energy in building.

In this study, a simulation of applying new working fluids other than the previously commercialized lithium bromide or ammonia was studied for a simultaneous cooling/heating absorption cycle that combines type 1 absorption cycle and type 2 absorption cycle. The new working fluid uses an ionic liquid as an absorbent, especially an imidazole-based ionic liquid. Water and R32 are used as refrigerants. The state of the solution mixed with the refrigerant and absorbent is predicted using the NRTL model. The ionic liquid to be used with water refrigerant is 1,3-dimethylimidazolium dimethylphosphate([DMIM][DMP]), 1-ethyl-3-methylimidazolium dimethylphosphate([EMIM][DMP]), 1-ethyl-3-methyl tetrafluoroborate([EMIM][BF₄]), and the ionic liquid to be used with R32 refrigerant is 1-hexyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide([HMIM][Tf₂N]). It was found that the water refrigerant and ionic liquid pairs were suitable for simultaneous cooling/heating absorption cycle with reasonable cooling and heating COPs, while R32 refrigerant and ionic liquid pair was not.

財政政策의 發展과 New Deal政策에 關한 考察

崔亨源 慶北專門大學 (영주경상전문대학) 1979 慶北專門大學 論文集 Vol.2 No.-

Fiscal Policy means all the economic policies through public finance under the modern capitalism and it can include all the economic policies practiced by government. In the industrial caitalism which has formed industrial capital by mercantilism, classical economists insisted on Cheap government which a nation looks on its economy. But every nation, which has been endured monopolistic capitalism and experienced the Great crisis of 1930's, has been taken High government that regulates the national economy as the positive fiscal policy, In my thesis, I investigated each chronical order of public finance policy which has been developed with the development of capitalism and divided the New Deal by president Roosevelt of United States of America into three: 1) relief spending policy 2) Pump-priming- policy 3) compensatory fiscal policy. And I studied these policies and problems and investigated fiscal policy of all the nations over the world based on the principles of supplementary fiscal policy in the postwar days.
