A cutting-edge air conditioning system that can be used to create negative-pressure wards without polluting the air is soon expected to join the fight against COVID-19, an academic-medical team told a news conference yesterday.
The team, led by National Chin-Yi University of Technology professor Weng Kuo-liang (翁國亮), developed the system, which utilizes the exchange of water molecules between indoor and outdoor environments under different pressure to create a cooler, cleaner space with low pressure.
The system uses separate pipes to collect outdoor air and discharge indoor air, as well as devices to disinfect air and absorb airborne particles, Weng said at the Ministry of Science and Technology in Taipei.

It can be used to convert an ordinary ward into a negative-pressure ward, while its energy conversion rate can exceed 85 percent, better than that of conventional air conditioners at 65 to 78 percent, he said.
The system, which costs NT$150,000 (US$4,946) would be used by Changhua-based Show Chwan Memorial Hospital in a collaborative project supported by the ministry, he said.
It could be used in other settings, such as households, hotels or regional centers, Weng added.
Taiwan has nearly 1,100 isolation beds, which would be sufficient as long as the nation keeps the COVID-19 pandemic under control, but the hospital hopes to take preemptive action by preparing more space for quarantine, the hospital’s Asian Institute of TeleSurgery dean Wayne Huang (黃士維) said.
Negative-pressure isolation wards for patients with infectious diseases have to be certified by the Ministry of Health and Welfare, while wards with negative-pressure conditions do not need such certification and could be used to quarantine people with suspected symptoms, he said.
The hospital would use the system developed by the team to convert an ordinary ward into negative-pressure space and build two quarantine stations with similar conditions outside the hospital, he said.
Under its industrial value creation program that started in 2017, the ministry has been supporting academics to commercialize their research achievements by working with business partners, Deputy Minister of Science and Technology Hsu Yu-chin (許有進) said.
Nineteen cases funded through the program have set up start-ups, and their aggregate commercial value have reached NT$4.77 billion, he said.
UNDER INVESTIGATION: Huang’s body was found just outside the bathroom and showed no signs of a struggle, and no alcohol or drugs were found Singer and actor Alien Huang (黃鴻升) was found dead at his home in Taipei’s Beitou District (北投) yesterday. He was 36. Huang was also known by the nickname Xiao Gui (“little ghost”). His body was found when his father went to check on him after being unable to reach him by telephone, and called emergency services to the house at 11am, the Taipei City Police Department said. Huang’s body, which was discovered just outside the bathroom, showed no signs of a physical struggle, and he appeared to have been dead for some time, police said, adding that no drugs or alcohol were
CONFIRMED IN PHILIPPINES: The CECC would conduct contact tracing for the migrant workers to determine if they had come into contact with elderly people or children Six Filipinos tested positive for COVID-19 upon returning home from Taiwan, the Central Epidemic Command Center (CECC) said yesterday as it reported a case of imported COVID-19 infection, bringing the number of confirmed cases in Taiwan to 500. Philippine authorities reported four of the cases through the National IHR Focal Point, while the other two were reported by the company that they had worked for in Taiwan. The six — five women and one man — are aged from their 20s to 40s, and worked as in-home care workers, domestic workers, factory workers and sailors in Taiwan, said Minister of Health and
The COVID-19 pandemic might not have originated from a seafood market in Wuhan, China, National Taiwan University College of Public Health professor Tony Chen (陳秀熙) said yesterday. While many countries are experiencing second waves of COVID-19 infections, many are also lifting lockdowns to revive their economies, allowing travelers to cross national borders, Chen said. Academics have been questioning whether genetic mutations in the novel coronavirus in different countries have made it more infectious, he added. Academics from different backgrounds have conducted phylogenetic analysis of SARS-CoV-2 genome sequences, he said, adding that the studies can help scientists understand how the virus spread among
The Taiwan Railways Administration (TRA) yesterday said that it has allocated NT$68 million (US$2.32 million) to build an Internet-of-things (IoT) platform that would facilitate proactive maintenance of the railway system and enhance service punctuality. The agency said that it decided to build the platform to promote horizontal communication among its departments after an investigation into the Puyuma Express derailment in October 2018 found that its four main departments — electrical engineering, rolling stock, construction and transportation — failed to share information with one another. The platform would use artificial intelligence to analyze maintenance data collected by its departments, including railway crossings,
