Tushe na Amfani: Raguwar Baya vs. Tsarin Gudanar da Baya

Iyakar farko tsakanin waɗannan nau'ikan samarun duk da ma'auni da kowanne ke ba da tare da tsarin gudanar da yanar gizo.
Differences in function comes down to basic design approaches. ARUs focus on moving large volumes of air at lower pressures with simple components, while AHUs handle complete environmental control through complex systems working together. When it comes to energy use, we see this divide clearly. ARUs use specially designed fans that move air efficiently, but AHUs consume much more electricity because they run multiple conditioning processes at once. That means ARUs work best in situations where just managing airflow is enough, without needing to control temperature or humidity levels. On the other hand, AHUs are necessary whenever buildings need to meet strict indoor air quality standards, maintain comfortable temperatures, or comply with regulations around healthy ventilation practices.
