Refrigeration systems designer

MEDIUM DemandLOW AI RiskGROWING in SL

Refrigeration Systems Designer is an elite specialisation combining deep engineering knowledge with real-world cold chain impact. You are one of very few people in Sri Lanka who can design a system that keeps food safe from farm to supermarket. The role is intellectually stimulating, well-compensated, and increasingly important as food export, pharmaceuticals, and cold chain development grow. Remote design consulting opens global earning potential.”

A Day in the Life

You design complete commercial and industrial refrigeration systems from first principles — calculating cooling loads, selecting equipment, producing technical drawings and specifications for cold store construction, food processing plants, and HVAC projects.

Calculate refrigeration load for cold stores, freezers, and process cooling applications
Select refrigeration equipment — condensing units, evaporators, expansion devices, controls
Design refrigerant piping layout — pipe sizing, routing, and support specifications
Produce system design drawings and schematics in AutoCAD
Specify control systems and automation for refrigeration plant
Prepare technical specifications and bills of quantities for procurement
Review and approve shop drawings and contractor submittals
Provide technical support during system commissioning

Work Environment

OFFICETeam: SMALLBUSINESS CASUALRemote: MEDIUM

Engineering consultancy office or in-house design team. Reviews are conducted at project sites but primary work is design and documentation. In Sri Lanka, refrigeration systems designers work in MEP engineering consultancies, refrigeration equipment companies, and large food processing companies.

Typical hours: 45h/week · WLB score 7/10 · OCCASIONAL overtime

Primarily office-based design work with project site visits. More structured hours than field trades. Occasional overtime during proposal deadlines and commissioning support.
