I’m preparing a full VRF layout for a new industrial facility on the outskirts of Chennai and need a specialist who can take the project from concept sketches to construction-ready drawings. The system must cover both heating and cooling loads and it will be built entirely around LG’s current VRF line-up, so familiarity with their outdoor and indoor units, piping constraints and control architecture is essential. Here’s what I expect at hand-over: • Detailed load calculations and equipment sizing that reflect Chennai’s climate and the thermal profile of an industrial process floor, offices, and ancillary spaces. • Single-line and double-line refrigerant piping diagrams showing branch selectors, refnet joints, and maximum allowable runs. • Control wiring schematics tied to LG’s central controller and BMS interface. • Coordinated AutoCAD (or Revit, if you prefer) drawings ready for my MEP set, with layer discipline and clear annotations. • Bill of materials listing model numbers, quantities, and recommended installation accessories. • A short design report summarizing diversity factors, simultaneous cooling/heating assumptions, and compliance with local ISHRAE guidelines. I already have architectural plans in DWG and the preliminary electrical schedule; you’ll get both on day one. Turnaround for the first draft should be one week, with two quick revision cycles to reach IFC status. If industrial-scale LG VRF is part of your everyday toolkit and you’re comfortable working remotely while aligning to Chennai norms, this assignment should be straightforward. Let me know your timeline and any similar projects you’ve wrapped recently, and we can lock in a start date right away.
