Siemens presents innovative and sustainable building technology at MCE 2024

Highly efficient chillers and heat pumps with magnetic expansion valve
One of the highlights will be the fast MVL702 magnetic expansion valve. The product, which has been designed specifically for refrigeration cycle processes in heat pump and chiller applications, is easy to integrate into any existing automation system and saves development and testing costs.

Its instant and precise response ensures system stability for commercial heat pumps and chillers as well as high energy efficiency, with an annual energy saving potential of up to 14 percent for end customers. Compared to a stepper motor technology, OEMs can gain up to 21 percent more heating capacity when implementing the valve into their existing heat pumps. With the integration of the MVL702, the heat pump continues to provide the same heating output, while consuming less energy and therefore delivering cost savings and improving sustainable operations. In addition, the valve closes automatically in case of power failure or cable disconnection, offering additional safety in chiller and heat pump applications.

Efficient heat pump automation for residential buildings
The Climatix system is part of the open digital business platform Siemens Xcelerator, which enables customers to accelerate their digital transformation easier, faster and at scale. The product allows OEMs in the HVACR sector to design, control, install, maintain, and innovate their offering in an efficient, open and sustainable way, while enabling Software-as-a-Service (SaaS) offerings. With the new Climatix S400 controller, Siemens provides equipment automation – specifically for residential HVACR applications, such as heat pumps and heat recovery ventilation. Its use favors the shift towards energy efficiency and decarbonization as due to its modularity, it can be employed in innovative and scalable heat pump applications. In addition, the controllers’ native cloud connectivity ensures remote access, which provides full transparency to OEMs and installers and allows fast, cost-efficient and sustainable reactions.
