본 연구는 기존에 사용하여 왔고, 최근에 온습도의 정확도를 검증하였던 강제 흡출식 복사선 차폐장치 (Aspirated Radiation Shield; ARS)와 모 기업(A 회사)에서 개발한 시스템으로 측정한 온습도를 비교하여 성능을 검토한 후, 시스템의 성능을 개선할 목적으로 수행되었다. 그 결과를 요약하면 다음과 같다. 딸기의 무성도가 두 계측시스템에 영향을 미친 경우를 제외하면, 전체적으로 볼 때 플레이트 2개의 시스템이 1개보다 복사선 차폐효과가 미미하지만 좋은 것으로 나타났다. 그리고 A회사의 시스템과 ARS장치로 측정한 최고온도의 전체적인 범위는 각각 20.5~53.3oC 및 17.8~44.1oC정도로써 A사 제품이 2.7~9.2oC정도 높게 나타났고, 일별 최대 편차는 12.2oC 정도였다. 평균온도의 경우, 두 기관의 전체적인 범위는 각각 12.4~38.6oC 및 11.8~32.7oC정도로써 A사 시스템이 0.6~5.9oC정도 높게 나타났고, 일별 최대 편차는 6.7oC정도 였다. 최저온도의 경우도 각각 4.2~28.6oC 및 2.9~26.4oC정도로써 A사 제품이 1.3~2.2oC정도 높게 나타났고, 일별 최대 편차는 2.9oC정도로써 두 기관의 장치로 측정한 온도에 편차가 있는 것으로 나타났다. 또한 상대습도의 경우, A회사와 ARS장치로 측정한 평균상대습도의 전체적인 범위는 각각 52.9~93.3% 및 55.3~96.5%정도로써 A회사의 시스템이 ARS장치보다 2.4~3.2%정도 낮게 나타나는 경향을 보였다. 그러나 일별로 비교하여 보면, 최대 18.0%정도 A회사의 시스템이 낮게 나타나는 날도 있었다. 결국 상대습도 도 온도와 마찬가지로 미미하긴 하지만 두 기관의 장치로 측정한 온도에 편차가 있는 것으로 나타났다.

This study compared the temperature and humidity measured by an aspirated radiation shield (ARS), the accuracy of which has been recently verified, and those measured by a system developed by the parent company (Company A) to investigate and improve the performance of the developed system. The results are as follows. Overall, the two-plate system had a lower radiation shielding effect than the one-plate system but showed better performance results when excluding the effect of strawberry vegetation on the systems. The overall maximum temperature ranges measured by company A’s system and the ARS were 20.5~53.3oC and 17.8~44.1oC, respectively. Thus, the maximum temperature measured by company A’s system was 2.7~9.2oC higher, and the maximum daily temperature difference was approximately 12.2oC. The overall average temperature measured by company A’s system and the ARS was 12.4~38.6oC and 11.8~32.7oC, respectively. Thus, the overall average temperature measured by company A’s system was 0.6~5.9oC higher, and the maximum daily temperature difference was approximately 6.7oC. The overall minimum temperature ranges measured by company A’s system and the ARS were 4.2~28.6oC and 2.9~26.4oC, respectively. Thus, the minimum temperature measured by company A’s system was 1.3~2.2oC higher, and the minimum daily temperature difference was approximately 2.9oC. In addition, the overall relative humidity ranges measured by company A’s system and the ARS were 52.9~93.3% and 55.3~96.5%, respectively. Thus, company A’s system showed a 2.4~3.2% lower relative humidity range than the ARS. However, there was a day when the relative humidity measured by company A’s system was 18.0% lower than that measured by the ARS at maximum. In conclusion, there were differences in the relative humidity measured by the two company’s devices, as in the temperature, although the differences were insignificant.
