Chiller System Engineer

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.
