Refrigerating fluid is the working medium in cooling systems such as central air-conditioning, heat pump air-conditioning, household air-conditioners, and other small-sized cooling equipment. The fluid circulates through the system, exchanging energy with the outside via changes in its thermodynamic states to provide cooling. Freon, the high-performing refrigerant introduced by DuPont…
The Internet of Things (IoT) is a vast information system based on the Internet, where RFID and wireless data communication connect the sensing layer with the application layer. This interconnection creates a comprehensive network that integrates human activity with the environment through sensing and control systems. The Importance of Low…
Scrubbing solution is added in the washing section during the fractional extraction process to eliminate impurities and fission fragments from the loaded organic phase. Various scrubbing solutions are used for different demands. ISWeek demonstrates how to detect the liquid level of scrubbing solutions in washing equipment before it gets too…
