| Abstract: |
| The long-term performance of heat exchangers in air conditioners degrades gradually as the increase of operation duration, which leads to the decline of cooling and heating capacity of air conditioner system. This paper is devoted to present the research status on long-term performance of heat exchangers in air conditioners, and focuses on factors such as dust deposition, corrosion, intermittent operation condition and bio-fouling. Research problems and direction of long-term performance of heat exchangers in air conditioners are pointed out. |
| Key words: heat exchanger long-term performance dust corrosion intermittent operation condition bio-fouling |
