Registered Public Utility Engineer - HVAC (China) study guide
Registered Public Utility Engineer - HVAC (China) · Work through your exam, one topic at a time.
The Registered Public Utility Engineer (HVAC) qualification - 注册公用设备工程师（暖通空调） - is a Chinese professional engineering credential for practitioners who design heating, ventilation, air conditioning, smoke control and building services systems. It is aimed at engineers working in design institutes, engineering consultancies, contractors and facility organisations who take responsibility for HVAC design decisions and sealed drawings. The Registered Public Utility Engineer - HVAC (China) study guide has 8 sections and about 3,097 words.
01HVAC Fundamentals and Load Calculations
Design heating and cooling loads are the numerical foundation of every later decision - equipment capacity, duct and pipe size, terminal selection and energy compliance. The exam tests whether you can build a load from its components, choose the correct outdoor design conditions for the project's climate zone, and carry a psychrometric state through to a supply-air quantity.
406 words, about 2 min02Heating Systems, Equipment and Design
Heating system design is judged on three things: the correct load, correctly corrected terminal capacity, and a hydraulically stable circuit. Chinese practice fixes design temperature differences (95/70 °C for high-temperature hot water, 85/60 or 75/50 °C for low-temperature, 45/35 °C for radiant floor), so most marks come from translating catalogue ratings into actual conditions.
411 words, about 2 min03Ventilation, Smoke Control and Industrial Exhaust
Ventilation and smoke control are examined together because both concern moving air through defined paths at defined rates. Industrial ventilation asks for capture and transport; smoke control asks for tenability in escape routes and for a fan that survives 280 °C.
406 words, about 2 min04Air Conditioning Systems, Air Handling and Refrigeration
This domain covers the plant-to-room chain: how the system type is chosen, how coil and fan are matched, how the refrigeration cycle behaves at part load, and how air is distributed. Central chilled water with fan coils plus dedicated outdoor air suits multi-room buildings; VAV suits large open floors with varying loads; DX split or multi-split suits small zones; radiant panels need separate ventilation because they handle sensible load only and risk condensation.
361 words, about 2 min05Building Energy Efficiency, Codes and Standards
Energy questions test whether you know which requirement is a mandatory provision (强制性条文) and which is a design option. GB 55015-2021 sets the performance floor for new buildings; GB 50189-2015 gives detailed public-building requirements; both are read against the climate zone of the project.
378 words, about 2 min06Automatic Control, Testing, Commissioning and Operation
These questions are the practical ones: can you sequence a plant so it does not trip, tune a loop so it does not hunt, and prove installed performance? Sensor location decides whether a loop can work: a discharge air sensor too close to the coil sees stratification; a room sensor in a dead corner controls the wrong space.
388 words, about 2 min07Fire Protection and Life-Safety Engineering for HVAC
Fire and life safety is where mechanical design meets GB 50016 and GB 51251. Questions usually concern boundaries, ratings and paths: where a duct crosses a fire compartment, how a stair is kept clear of smoke, and what the fan must survive.
363 words, about 2 min08Professional Practice and Engineering Ethics
Professional practice tests judgement as much as knowledge. As a registered public utility engineer (暖通空调) you seal drawings, carry design responsibility, and must refuse instructions that breach mandatory provisions - even when the client is paying.
