摘要
功率超声在某些介质中传播可以产生热效应、机械效应和空化效应。这些效应在特殊情况下,可以起到促进传热、传质,产生高频振动等效果。超声技术在暖通空调与制冷领域多方面有应用和研究,如雾化、除尘、强化换热等。本文介绍超声技术在暖通空调与制冷领域的研究和应用现状,及其发展重点。
The heat effect, vibration and cavitation occur with the high power ultrasonic spreading in some medium. Such efforts can promote heat transfer, mass transfer or bring high frequency vibration in some specific situation. The application and study of ultrasonic technique has appeared in many areas of HVAC＆R field, such as atomization, dust catching and heat transfer promoting. This paper describes the present situation of ultrasonic technique used in HVAC＆R field, and overlooks the investigation emphasis in future.
