Job Description

POSITION OBJECTIVE:

Chiller Design & Integration: Lead the thermodynamic design, component selection, and system integration of Magnetic Bearing Centrifugal Chillers, with a specific focus on Danfoss Turbocor oil-free compressor technology.

Global Collaboration: Serve as the key technical bridge between the local team and the US G&D Chiller (Global Design) Chiller team to ensure alignment on global specifications and technology platforms.

Total Solution Synergy: Support the integration of the Chiller with CDU (Coolant Distribution Unit) and Fan Array systems to deliver a seamless "Total Solution" for high-density data centers.

Local Supplier & Tech Qualification: Supervise and qualify Chinese component suppliers (heat exchangers, pressure vessels, controls) to support local assembly and global compliance.

RESPONSIBILITIES:

System Modeling & Simulation: Perform refrigerant cycle simulations, heat transfer calculations, and thermodynamic analyses to optimize chiller system performance (COP, IPLV/NPLV).

Danfoss Turbocor Application: Lead the selection, configuration, and control logic design for Danfoss Turbocor compressors. Establish optimal running parameters and envelope control algorithms.

Localization Leadership: Lead localization work to seamless cooperated with G&D Chiller engineering team to transform global specifications and technical data to ensure meeting customer requirements.

Testing & Validation: Plan and execute Factory Acceptance Tests (FAT) and prototype verification under performance standards.

Technical Support & Sourcing Assistance: Provide advanced technical guidance to Global Sourcing for qualifying core components (e.g., flooded/falling-film evaporators, variable speed drives).

QUALIFICATIONS:

Experience: At least 5-8 years of experience in the design and development of large-scale water chillers, with a proven track record (at least 3 years) of hands-on project experience with Danfoss Turbocor (or equivalent magnetic bearing) compressor systems.

Education: Bachelor’s degree or above in Refrigeration, Cryogenic Engineering, Thermal Energy Engineering, or Mechanical Engineering.

Technical Expertise:

• Deep, practical knowledge of refrigeration cycle dynamics, and variable-speed centrifugal compressor systems.
• Proficient with thermodynamic simulation software (e.g., NIST Refprop, Aspen, or proprietary chiller selection tools).

Language: Fluent written and spoken English is mandatory for technical alignment with the US G&D Chiller Director and overseas engineering teams.

Software: Proficient in CAD software (Pro/E, Solidworks, UG), and thermal simulation/CFD tools.

Competence Requirement:

Leadership Competency: Strong Collaboration across global cultures, Strategic Thinking for product roadmaps, and Problem-Solving under tight project timelines.

Functional Competency: Excellence in Thermodynamic Analysis, Chiller Control Logic Development, and Supplier Technical Auditing.
