The performance of regenerator in heat pump integrated liquid desiccant (LD) system was investigated for the operation in winter. The performance parameters for regenerator were the regeneration effectiveness and enthalpy exchange effectiveness. There were five independent parameters of inlet air temperature, inlet air humidity ratio, inlet solution temperature, concentration of solution and liquid-to-gas ratio. The experimental model was constructed using an adiabatic cross flow regenerator with lithium chloride solution. Based on 2<SUP>k</SUP> and 3<SUP>k</SUP> factorial design method, total 48 experiment sets were designed to develop prediction models for two performance parameters. The results showed that the solution temperature and liquit-to-gas ratio have significant effects on the regeneration effectiveness and enthalpy exchange effectiveness of regenerator. In addition, the amount of humidification was ranged from 3.23 g/㎏a to 51.18 g/㎏a, therefore it was enough for humidification system in winter.

물건을 이용 가치를 중심에 두고 구매하는 형태는 공유경제라는 새로운 소비문화를 이끌어내었다. 2011년 이후 국내에서는 다양한 공유기업의 서비스가 시작되었으며, 그 중에 차량 공유는 합리성, 환경성, 경제성 측면에서 가장 주목을 받고 있는 분야다. 차량 공유 서비스는 운영 구조에 따라 P2P와 B2C로 나눌 수 있으며 공유 대상에 따라서는 좌석 일부를 공유하는 승차 공유, 차량 전체를 공유하는 차량 공유로 분류할 수 있다. 현재 시행중인 차량 공유를 지속 성장이 가능한 서비스로 만들기 위해서는 영역과 관계적 관점에서의 조사가 필요한 시점이다. 따라서 본 연구에서는 공간의 영역과 관계적 관점을 기준으로 차량 공유 서비스에 미치는 요인을 이론적으로 논의하였다. 연구 결과, 영역적 관점에서 공적 영역과 사적 영역의 형성은 서비스 유형과 시간 요인에 영향을 받았다. 차량전체 공유 서비스는 공적 공간인 차량 안에서 일정 시간동안 개인의 사적 영역을 형성하는 양상을 보였다. 반면, 승차 공유 서비스는 타인의 사적 영역과 나의 사적영역이 공적 공간 안에서 공존한다. 이러한 관계는 한회의 공유 서비스가 종료되는 시점까지 유지되며 영역은 공유경제 서비스가 지속되는 동안 수차례에 거쳐 순환되는 구조이다. 관계적 관점에서는 공유적 관계와 교환적 관계를 통해 사적영역이 형성되는 범위에 대해 고찰하였다. 공유경제 참여자 간에 공유적 관계가 형성될수록 사적 영역이 확장되지만, 교환적 관계가 형성되면 사적 영역이 축소되고 호혜성의 원칙에 따라 행동하는 양상이 보였다. 따라서 공유경제의 공동체적 특성을 유지하고 지속적인 공유경제의 유지를 위해서는 참여자들이 공유적 관계를 지향해야 한다. The form of purchasing goods based on use value led to a new consumption culture called sharing economy. Since 2011, various sharing companies have begun to provide services in Korea. Among various sharing area, car sharing have attracted people because it is rational, environmental, and economical. It could be divided into P2P and B2C depending on the operation structure. Also, it could be classified as car sharing which shares the entire vehicle and carpool which shares a part of the seat depending on sharing object. To discuss a sustainable development of car sharing economy’s direction, research for a spatial and relational perspective is needed. Therefore, in this study, the factors affecting the car sharing service based on spatial relations and contracting relations were theoretically discussed. As a result, the formation of public and private space was influenced by service type and time factor. The car sharing service showed the shape of the private space during certain period of time in the public space. On the other hand, private spaces in the carpool service coexists with others. This relationship is maintained until the end of the one-time sharing service, and the space is circulated several times while the sharing economy service continues. From the point for view of the relationship, the formed domain of private space was examined through the communal and exchange relationship. The private space is expanded as the communal relationship is formed between the participants of the sharing economy. However, when the exchange relationship is formed, participants reduced the private space and acted according the principle of reciprocity. Therefore, in order to maintain a sustainable sharing economy, the participants should aim for a communal relationship.

Objectives The purpose of this study is to understand formation courses of the ten types of LBP (十種腰痛) in Korean medicine through reviewing classic literatures. Methods We summarized sentences describing syndrome differentiation of LBP directly in Uibujeonrok (醫部全錄) and Donguibogam (東醫寶鑑), and then organized similarities and differences among diagnostic factors described in the classic literatures. Results In most of the classics LBP was classified according to the cause but the causes varied depending on the classic literatures. Cheonkeumbang (千金方) tried to suggest a reasonable classification of LBP in a relatively early age. In Dangyesimbeop (丹溪心法) the causes of LBP were divided into 6 factors; qi movement stagnation (氣鬱), dampness-heat (濕熱), kidney deficiency (腎虛), static blood (瘀血), sprain (挫閃) and phlegm accumulation (積痰). It had a lot of influence on the classic literatures published later. Donguibogam was also influenced by the Dangyesimbeop and the ten types of LBP in Donguibogam was similar to the information on the classification shown in Uihakipmun (醫學入門) and Uijongpildok (醫宗必讀). Conclusions We verified universality of the ten types of LBP; kidney deficiency, phlegm-retained fluid (痰飮), food accumulation (食積), sprain, static blood, wind (風), cold (寒), dampness (濕), dampness-heat and qi (氣).

This study aims to evaluate the energy saving potential of a fuel cell integrated thermoelectric heat pump and liquid desiccant assisted dedicated outdoor air system (TELDOAS) for building energy retrofit via detailed energy simulations. The target building is general public office building, and the reference system is enthalpy recovery ventilator with electric heat pump (EHP) with a humidifier for air conditioning. For a detailed energy simulation, all the simulation models of each component based on the mathematical and empirical models were integrated using MATLAB, and simulation was conducted in hourly progress. As a result, proposed system can save 49% of annual operation energy by using TELDOAS instead of ERV and steam humidifier except the generated electricity from fuel cell. It can be achieved by efficiently reclaiming the waste heat from fuel cell.

This paper proposes a thermoelectric module radiant cooling panel (TEM-RCP) and its desirable arrangement of thermoelectric modules (TEMs) for uniform temperature distribution. The design methods for the TME-RCP was developed based on the semi-black box model of TEM and the two-dimensional finite difference method. A mock-up model of the TEM-RCP was constructed to verify the proposed model and results. The constructed TEM-RCP consists of seven TEMs, an aluminum panel, a heat sink attached to the TEMs, air duct and fan for heat rejection. The TEM is a solid state heat pump operated by direct current based on the Peltier effect. When the panel temperature at the aluminum radiant panel was maintained at 16°C during operation, the heat rejection was occurred at the hot side of TEM and it was removed using forced convection by outside air. The main design factor in this study was the panel temperature distribution. Therefore, the suitable arrangement and interval between TEMs were investigated not to exceed the maximum temperature difference of 3°C across a given grid. As a result, the triangular grid was found as the best grid for an uniform temperature distribution of the TEM-RCP. The optimal interval between the TEMs was 0.2 m to 0.3 m according to the room condition and operation characteristics of the TEM. The optimized results were validated through experiments using the mock-up model of TEM-RCP.
