초록

본 연구는 저온환경에서의 평판형 열교환기에 대해 제빙을 억제할 수 있는 방법을 살펴보았으며, 그 방법으로 초음파의 발생에 따른 제빙특성을 관찰하였다. 본 실험에서 최적의 조건을 찾아내기 위해 에틸렌글리콜을 브라인으로 사용하고, 온도는 $-8{\sim}-16^{\circ}C$로 순환시켰으며, 제빙에 사용된 물은 1~3mm 두께로 공급하여 데이터를 기록하였다. 또한 초음파의 발생정도에 따른 변화를 확인하기 위해 출력을 조절하여 실험을 진행하였다. 그 결과 제빙억제 효과는 브라인 온도, 제빙두께, 초음파 주파수의 영향을 받는 것을 알 수 있었다.

This study attempted to examine a method of anti-freezing on a plate-type heat exchanger in a low-temperature environment. Freezing condition was observed after ultrasonic waves were generated. Data were recorded to determine the optimal conditions for freezing. Ethylene glycol, which is commonly used in antifreeze formulations, was used as the brine, and the temperature was varied between -8 and $-16^{\circ}C$. The water for freezing provided by the thickness of 1-3 mm. In addition, experiments were conducted by adjusting the output to identify the changes that occurred due to the incidence of ultrasonic energy. The results of the anti-freezing effect were brine temperature, freezing thickness, and frequency band of ultrasonic waves.
