Forskning
Guangyu Caos forskning fokuserer på innendørs luftkvalitet og ventilasjonssystemer, med særlig vekt på helsemiljøer. Hans arbeid har bidratt med verdifulle innsikter til byggeteknikk og miljøhelse.
Hans forskning dreier seg om å forstå og forbedre luftfordelingen i ulike rom, spesielt operasjonsrom og bygninger. Han benytter en kombinasjon av eksperimentelle studier og matematisk modellering for å vurdere effektiviteten av ulike ventilasjonsstrategier for å håndtere luftbårne forurensninger som virus og bakterier.
Sentrale områder i hans forskning inkluderer:
-
Ventilasjon av operasjonsrom: Hans studier dykker ned i kompleksitetene ved ventilasjonssystemer i operasjonsrom. Han undersøker effektene av luftfordelingsmønstre, temperatur og bevegelse av kirurgisk personell på forurensningsnivåer under operasjoner.
-
Luftbåren sykdomsoverføring: Hans studier fokuserer på luftbåren overføring av sykdommer, spesielt i sammenheng med COVID-19. Han undersøker ventilasjonshastigheter, luftfuktighet og luftfordelingens rolle for å minimere risikoen for viral forurensning innendørs.
-
Innendørs luftkvalitet på skoler: Han samarbeider om forskning som undersøker innendørs luftkvalitet på skoler. Dette arbeidet vurderer kritisk sammenhengen mellom innendørs luftkvalitet og studenthelse, og bidrar til bedre skolemiljøer.
-
Eksperimentelle og simulerte studier: Han kombinerer eksperimentelle målinger med datamodellering for å vurdere ventilasjonsstrategier. Forskningen hans veileder utviklingen av effektive retningslinjer for å forbedre innendørs luftkvalitet og begrense risikoen for forurensning.
Alt i alt fremmer Guangyu Caos forskning vår kunnskap om innendørs luftkvalitet, ventilasjonssystemer og deres konsekvenser for menneskers helse i ulike miljøer. Hans tverrfaglige tilnærming, som kombinerer praktiske data, matematisk modellering og innsikter fra virkeligheten, adresserer kritiske bekymringer knyttet til kontroll av forurensning og bærekraftige byggepraksiser.
