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 valve designed specifically to increase efficiencies of chillers and heat pumps.

Debuted at this week’s MCE2024 in Milan, the MVL702 is said to be easy to integrate into any existing automation system and saves development and testing costs. Its instant and precise response is said to ensure system stability for commercial heat pumps and chillers as well as high energy efficiency, with an annual energy saving potential of up to 14% for end customers. Compared to a stepper motor technology, Siemens maintains that OEMs can gain up to 21% more heating capacity when implementing the valve into their existing heat pumps. The valve also closes automatically in the event of a power failure or cable disconnection, offering additional safety in chiller and heat pump applications.
