HVAC Fundamentals Every MEP Engineer in Dubai Must Know

HVAC fundamentals explained through a Dubai building — from the chiller to the room, step by step. It's 45°C outside and 22°C inside. That heat doesn't disappear — in this video I trace the exact path it takes out of the building, so you understand how an HVAC system actually works instead of memorising component names. This is HVAC basics for MEP engineers, mechanical engineers, and students working or planning to work in Dubai and the UAE. WHAT YOU'LL LEARN • The full cooling loop — chiller, chilled water pump, AHU, ducts, room, return • AHU working principle: coil, filter, fan and control valves explained • Chiller basics: evaporator, condenser and compressor — why it rejects heat rather than "making cold" • Cooling load in plain terms, and how chiller capacity is actually sized for a Dubai project • The three mistakes that cause failed designs — no diversity, undersized chiller, ignored fresh air load CHAPTERS 0:00 Where the heat actually goes 0:30 What you'll be able to do by the end 1:30 The cooling loop, start to finish 3:30 Inside the AHU 5:30 Chiller basics 7:30 How a chiller gets sized for a Dubai project 9:30 Common design mistakes 10:30 Recap WHO THIS IS FOR MEP engineers, mechanical and public health designers, fresh graduates and construction professionals working in Dubai and the wider UAE. If this was useful, subscribe — the channel covers practical MEP and building services tutorials focused on DEWA requirements, load schedules, HVAC and Dubai/UAE standards.
