This paper describes the investigation on current state of cold storage facilities, and analysis on the demand prediction in the near future. And based on the analysis results, we prospect the scale of cold storage facilities in the near future. The main analysis results are summarized by the followings ; The present circumstances of cold storage facility are determined by investigating actual loading capacity, average stock amounts, and return number of cold storage facility. From the results, the present situation for cold storage facility is about 3% over. It is found that the average stock amounts increase gradually, and accordingly that the demand of cold storage facility is predicted to be increased, resulting that the capacity of cold storage facilities in 2013 expects to reach up to 5,250,000 ton. It is considered that the results of demand prediction has significant implications on the management of cold storage facility in the near future.

It can be said that refrigeration and air-conditioning technology in Korea dates back to the ancient Shilla dynasty, all the way up to the Sokkuram(700s) and Seokbinggo(1700s). But modem refrigeration and air-conditioning technology was first developed in and introduced to Korea in the 1960s with the modernization of Korea. Today it is at a level which meets that of advanced countries in both the industrial and domestic fields. 62 million units of refrigeration and air-conditioning machinery and equipment were produced in 2003, worth a total of 7.7 trillion won(about 7.7 thousand million US$). As of 2003, there were about 700 companies that owned cold storage / freezing / refrigeration facilities, with cold storage capacity of about 2 million ton and capacity per company of about 3 thousand ton. This facilities most are continuously expanding and automatizing their facilities.

이 논문에서 암모니아 가스의 실내 누출 및 확산 현상을 FLACS 소프트웨어를 이용하여 시뮬레이션한 결과, 암모니아 가스가 실내에서 폭발 위험분위기를 쉽게 형성함을 확인하였다. 따라서 암모니아 가스를 냉매가스로 사용하는 고압가스 냉동제조시설의 냉동실은 환기장치를 갖추거나 가스누출검지경보장치를 설치하여야 한다. 그러나 냉동시설의 특성상 이들 설비를 설치할 수 없기 때문에 재발방지대책으로 암모니아 가스설비의 전기설비는 방폭구조로 설치하고 고압가스 냉동제조시설에서 가스누출 등의 이상사태가 발생하는 경우에 사업장 안의 모든 종사자가 신속히 대피할 수 있도록 통신시설을 설치할 필요가 있다.

This paper describes the analysis on freeze and refrigeration capacity of cold storage facilities for fisheries products during the last 15 years. And based on the analysis results, we prospect the number and scale of cold storage facilities in the near future. The main analysis results are summarized by the followings; Under the present conditions, the number and scale of our facilities is 879 and 3,586,824 ton, respectively. In comparison of the present and last 15 years ago, the business number increases about 22%, the accommodation capacity increases approximately 80%. In the reported update reference with the related data during the last 15 years, the capacity of cold storage facilities in 2011 expects to reach up to 4,600,000 ton. The newlyestablished facility in 2011 has the function of a multi-purpose distribution center as well as the existing cold storage, but this facilities converges in the capital area. Therefore, in this paper, we provided the basic reference data for the present situation and prediction of our cold storage facilities. But it is necessary to investigate and analyse widely our cold storage facilities for fisheries products in the near future.

본 연구에서는 냉장, 냉동 창고의 기초 자료가 부족하여, 불완전하기 때문에 이러한 기초자료를 제공하기 위하여 냉장 냉동 창고의 일반현황을 제시하는 데 목적이 있다. 조사내용은 냉장 냉동 창고의 일반적인 현황으로는 매출액, 자본금(출자금), 창고종류별 보유현황, 보관면적, 냉장냉동 시설용량 등과 설비현황으로는 랙의 유무, 건축물 구조 및 층고, 모유설비현황 등을 조사하였다. 조사결과에 따르면 지역별 분포는 수도권과 부산지역이 전체의 86.7%로 대부분을 차지하였으며 이들 지역이 평균보관면적 또한 큰 것으로 나타났다. 또한 전체 업체의 80%이상이 보세장치장을 보유하고 있는 것으로 조사되었으며, 냉장 냉동 창고의 면적 및 용량은 고른 분포를 보였다. 건축물 구조는 철근 콘크리트 구조가 대부분이었으며 설비의 경우 랙 설치 업체가 전체의 25%로 나타나 설치율이 낮았으며 랙의 설치여부와 자본금 및 매출액 규모와는 통계적 유의성을 보이지 않았다. 또한 보유설비는 화물용 승강기, 정보시스템, 도크 순이었으며 하역장비로는 지게차가 평균 9.1대, 리치스태커는 평균 2.2대 인 것으로 조사되었다. 본 조사가 국내 냉장 냉동 산업의 실태파악과 예측, 발전에 기초가 될 것으로 생각하며 향후 좀 더 세밀한 연구가 추가적으로 진행되어야 할 것이다.

Environmental control facilities are used to simulate an environment or combination of environments under which many kinds of research and tests can be performed. The design of the control system to maintain desired environmental conditions is essential to proper operation of the facility. A simulation model of the facility has been developed by analyzing each component of the system thermodynamically with necessary properties and heat transfer relations. Using the system simulation model, the required characteristics of the control system has been investigated. PI controller is considered as the most probable controller for this kind of the facility, and electric heater power is shown as the Proper manipulated variable for temperature control.

Facility data is created throughout the design and construction phase. But the most facility managers bear significant costs that arise from the lack of interoperability with facility lifecycle. This paper is concerned with the way to collect facility data using BIM technology. The aim of this paper is to suggest BIM data modeling guide for the facility management using the information that need to be delivered from design and construction phase to operation and management phase. The BIM data modeling guide focus on the properties of mechanical equipment. It is to be hoped that this study will contribute to collect facility data from as-built BIM data and to build facility management system database without difficulty.

On account of the technological development, intelligent building is on increasing where the artificial regulation on indoor environment is possible, thence the concern about those facilities such as water-supply facility, water-heater and drainage facility has becomes higher. However, due to diversification and complicated system of the facility-equipments, the noise generating from such facility equipment is gradually becoming a problem, and since especially equipment noises arising at the machine room frequently infringe into the resident's pleasant living environment with the complex types of an air-borne sound and a structure-borne sound, it is becoming the civil complaint. On such viewpoint, this Study ever observed the characteristics of noise generating from various facility-equipments in the building, and intended to evaluate the facility-noises by use of the valuation index such as PSIL, N, NC, NR. As result of, the facilities noise which happens in the machine room makes normal conversation very difficult due to high sound pressure level. Based on such data, this study is willing to present it as an essential material for establishment an efficient measure against the facility-noises arising at machine room hereafter.
