Abstract: Due to the report of incidences of damage caused by chloride deicers in recent years, the need for eco-friendly deicers has increased. However, it is necessary to enhance the quality and economic feasibility. The present study derived the optimal mix of eco-friendly deicers utilizing industrial by-products and compared their performance with those of existing chloride deicers. The test results showed that the eco-friendly deicer had better performance in terms of freezing point and in ice melting tests than calcium chloride-based deicers. The eco-friendly deicer displayed little corrosion in the steel corrosion test. In the snow melting performance evaluation, liquid eco-friendly deicers demonstrated a better performance in initial snow melting than powder calcium chloride-based deicers, verifying their applicability to real sites.

Abstract: New designed residential-sized refrigerators subjected to repetitive random vibrations can be damaged during transportation. The damage consists of fracturing of the tubes between the compressor and condenser and tearing of the compressor rubber mounts. As the reliability quantitative (RQ) test specifications, parametric accelerated life testing (ALT) through sample inspections and corrective action plans was used to identify the key control parameters for the connecting tubes and compressor rubber mounts. The shape of failures in refrigerators found experimentally was identical to those of the failed samples in field. The connecting tube fractures resulted from the problematic shape of the compressor rubber mount. To correct these problems, the mounts and connecting tubes were redesigned. The refrigerators with targeted B1 life were expected to survive without failure during rail transport. Parametric ALTs were effective in identifying the missing design parameters of mechanical system
