VRF / VRV System Design — Professional Online Course

From room loads to a buildable VRF drawing set

One outdoor unit. Dozens of rooms. Two copper pipes. Every decision in between is yours. This course walks you through that decision chain the way an experienced design engineer does it on a real project.

Start the free modules (1–3) — no account needed

What you will be able to do

• Calculate room cooling loads component by component and read the result like a senior engineer
• Choose and place the right indoor unit — cassette, ducted, wall, ceiling-suspended, floor
• Size outdoor units and judge the connection ratio: what 90 %, 100 % and 130 % really mean on site
• Size every refrigerant pipe segment, check length and height limits, calculate the additional charge
• Design condensate drainage that drains: slopes, traps, pumps, risers
• Check refrigerant safety in the smallest room (EN 378 / ISO 5149) and fix it when it fails
• Integrate fresh air and heat recovery; coordinate power, controls and ceilings
• Produce a clean drawing set — and spot the ten mistakes reviewers find most often

What is inside

• 12 narrated modules with animated diagrams (refrigerant flow, airflow, leaks, drains)
• Two complete worked projects as DWG + DXF drawing sets (plans, riser diagrams, schedules)
• VRF CAD block library — 42 brand-neutral blocks (indoor and outdoor units, branch kits, BS boxes, drain and control symbols, tag blocks with attributes) in DWG + DXF, mm and m versions
• 137-page PDF course book with every diagram
• Interactive “find the 10 mistakes” exercise and check questions in every module
• Final exam — retake as often as you need, every attempt draws new questions
• Certificate with QR verification, signed by Serhat Çelik, M.Sc. Mechanical Engineer
