초록

본 연구는 무창계사에 대한 효율 비교분석 연구가 전무한 실정으로 무창계사의 환경효율을 검증하고자 하였다. 본 실험은 축산기술연구소 신축 실험계사에서 2002년 5월 9일에서 5월 30일 사이에 실시하였으며 실험결과는 다음과 같다. 1. 무창계사는 외부의 기온은 9.6${\sim}$21.2$^{\circ}C$로 편차는 약 11.6$^{\circ}C$를 나타내었는데 비하여 단열이 우수한 무창계사에서는 병아리 사육적온기인 32${\sim}$33$^{\circ}C$ 범위를 유지하여 약간의 보조열원으로 낮과 밤의 편차는 2$^{\circ}C$ 이상 나타나지 않아 온도효율이 높았다. 2. 공기풍속에 있어서는 무창계사는 상부 0.57 m/sec, 하부 0.04 m/sec로 각각 나타나, 계사내 적정 풍속유지를 위한 덕트입기구의 천공으로 인하여 계사내 전체공간에서 공기의 유속흐름 분포가 고르게 나타났다. 이상의 실험결과를 종합해 볼 때 조사대상이 된 무창계사의 온도 및 습도 환경이 우수하게 나타났으며, 특히 공기속도는 계사 공간 내에서 아주 고른 분포를 가져와 측벽 덕트 입기사설과 측벽 배기기스템이 우수하였다.

The experiment was conducted to evaluate a ventilation system, which was devised to encourage farmers to use the enclosed poultry housing system. The study was observed in the National Livestock Research Institute from May 9 to May 30 in 2002. The main results of the experiment are as follows: 1. Although the outside temperature of the enclosed poultry house was 9.6 ${\sim}$ 21.2$^{\circ}C$ with 11.6$^{\circ}C$ variation, the house with an excellent heat insulation was maintained at 32${\sim}$33$^{\circ}C$ in a variation of 2$^{\circ}C$ which is within the range of the optimal temperature for broiler, being aided with two small electric heaters. 2. The average of air flow rates of the upper, middle and low parts of the room in the broiler house were detected at 0.57, 0.22 and 0.04 m/sec, respectively. The air flow in the whole room was distibuted uniformly by a perforated duct. In conclusion, heat and humidity could be controlled without any problem in this enclosed housing system. Especially, air flow in all parts of the room was detected in uniform rates, resulting in the better ventilation performance with air inhalation through the duct and air exhaust through the side walls of the house.
