HVAC Systems Design — Heating, Cooling & Ventilation (Course)

Heat in, heat out, fresh air through — and every number checked. A building’s HVAC system is a chain: the heat loss of a room, the radiator under its window, the pipe and the pump, the heat pump on the roof, the chiller in the basement, the air handling unit and the duct that reaches the diffuser. If one link is guessed, the whole chain fails. This course teaches you to design the whole chain the way an experienced engineer does — from the physics to the plant room, from the calculation sheet to the drawing.

Who it is for

HVAC and MEP design engineers in their first years, mechanical engineers moving into building services, engineers who know one part of HVAC and want the whole picture, reviewers who check HVAC submittals, and contractors’ design teams.

What you will be able to do

• Set design conditions and calculate room-by-room heat losses and cooling loads — by hand, so you can check any software
• Choose and size heat sources: condensing boilers, cascades, district heating substations and heat pumps
• Select radiators, underfloor heating, fan coils, trench convectors, radiant panels and air curtains — including low-temperature design for heat pumps
• Size pipes, pumps, expansion vessels and control valves, and balance a hydronic system
• Design domestic hot water systems that meet peak demand and keep Legionella out
• Understand the refrigeration cycle, select DX, VRF and chiller systems, and design chilled water and condenser water systems
• Calculate ventilation rates, work on the psychrometric chart, specify AHUs with heat recovery, and size ducts, diffusers and fans
• Design car park, kitchen and special ventilation, and control noise and vibration

What this course is not

It is not a manufacturer training and is not tied to any brand; catalogue values in the examples are illustrative. It summarises ASHRAE, EN, ISO and CIBSE-type guidance in its own words and does not replace them — always design to the standards and editions in force for your project. See our refund policy.
