西门子新型阀门提高热泵效率

编译/ 冷热前行

西门子公布了一种新型磁性膨胀阀的详细信息，专为提高冷水机组和热泵的效率而设计。

在近于米兰举行的MCE2024展会上亮相，据说可以轻松集成到任何现有的自动化系统中，并节省开发和测试成本。 

据称，其即时性和jingque性可确保商用热泵和冷水机组的系统稳定性，以及高能效，为终客户提供高达14%的年节能潜力。 

与步进电机技术相比，当将该阀门纳入现有热泵时，OEM厂商可以获得高达21%的更多供热能力。 

如果发生电源故障或电缆断开，该阀门还会自动关闭，从而为冷水机组和热泵应用提供额外的安全性。

Siemens has revealed details of a new magnetic expansion valvedesigned specifically to increase efficiencies of chillers and heatpumps.

Debuted at this week’s MCE2024 in Milan, the MVL702 issaid to be easy to integrate into any existing automation systemand saves development and testing costs. Its instant and precise response is said to ensure systemstability for commercial heat pumps and chillers as well as highenergy efficiency, with an annual energy saving potential of up to14% for end customers. Compared to a stepper motor technology, Siemens maintainsthat OEMs can gain up to 21% more heating capacity whenimplementing the valve into their existing heatpumps. The valve also closes automatically in the event of apower failure or cable disconnection, offering additional safety inchiller and heat pump applications.
