Developed by Chinese researchers, the system is designed to reach a heating capacity of 5.7 kW and an overall coefficient of performance of 1.40 at nominal conditions. It is made with an engine unit, a heat pump unit, and a gas resonator unit in a loop.Researchers led by the Chinese Academy of Sciences have designed a novel thermoacoustic heat pump system that they claim is able to use medium/low-grade heat for heating supply in domestic applications. "The system consists of one simple thermoacoustic energy-conversion unit with a direct-coupling configuration, which greatly reduces the system ...Den vollständigen Artikel lesen ...
