Categories	Description
AHU	The basic function of an Air Handling Unit is to take in outdoor air, re-condition it and supply it to a building, as part of a heating, ventilating, and air-conditioning (HVAC) system.
Basement	Basement floors of UM Campus are majorly serve as carpark and MEP plant rooms.
Central Chiller Plant	Central Chiller Plant located at N22 building serve the air condition system for UM Campus north buildings, such as University Hall, Sports Complex, Research Buildings, Faculty of Science and Technology, Faculty of Health Sciences. A central chiller plant usually has higher efficiency than separate chiller plants.
Chiller	A chiller is a machine that removes heat from a liquid via a vapor-compression or absorption refrigeration cycle for HVAC purpose.
Cooling Tower	A cooling tower disposes unwanted heat from a chiller through the cooling of a water stream to a lower temperature.
CW Pump	The pump of cold water on cooling tower loop.
ELV	ELV systems usually stand for a variety of sub-systems for control and security purpose utilizing Extra-Low Voltage signal, e.g. video intercom, voice broadcasting, CCTV, access control, HVAC control, building management system, data network.
External User	The feeder serves the external user such as restaurant and retail store.
Fire	Fire service plays an important role in life safety in buildings. It consists of automatic fire alarm system (AFA), sprinkler, hydrant, hose reel, inert gas suppression system.
Heat Pump	Heat pump applies the refrigeration-type cycle to absorb heat from a cold space (outdoor) and releasing it to a warmer space (indoor).
Hot Water Pump	Pump for chiller working in refrigeration-type cycle to deliver heat to indoor.
HVAC	Heating, Ventilating, and Air-Conditioning. Its goal is to provide acceptable thermal comfort and indoor air quality.
HVAC Heat Pump	Heat pump applies the refrigeration-type cycle to absorb heat from a cold space (outdoor) and releasing it to a warmer space (indoor).
Incomer	The cable which directs the electricity from upstream to distribution panel.
Lab	Short form of laboratory, in where experiments are conducted.
Landscape	Landscape architecture is the design of outdoor areas, landmarks, and structures, incorporating both natural plants and man-made materials, e.g. landscape lighting, fountain, waterfall.
Lift	An elevator is a type of vertical transportation machine which delivers people or goods between floors of a building.
Lighting And Socket	Lighting includes both illumination of space and decorative purpose with the use of lamps. Socket is for electric appliance to plug-in to use AC power supply.
Others
Plumbing And Drainage	Plumbing system is to supply water in a building. Drainage system is for unwanted water or waste to be discharged away.
Primary CHW Pump	The pump of primary chilled water loop (chiller side) in a chiller and plate heat exchanger system.
Pump Cooling Fan	Fan inside pump to prevent overheated.
QGBT	Short formed in Portuguese “Quadro Geral de Baixa Tensão”, also known as Low Voltage Switch Board in English, an assembly of switchgear to direct incoming electricity from supply source to downsteam distribution panels, with necessary switching, current protection, and metering function etc.
Refill Water Pump	To refill water to feed and expansion tank for chiller.
Secondary CHW Pump	The pump of secondary chilled water loop (demand side) in a chiller and plate heat exchanger system.
Stage
Swimming Pool	Swimming pool located inside Sport Complex.
Valve	To control flow rate of liquid.
VRV	Variable Refrigerant Volume is an outdoor condensing unit to circulate refrigerant efficiently within the building to multiple fan-coil units (FCUs) for air-conditioning purpose.
