Structure refers to the structure that determines the standing and bearing parts of houses, bridges and tunnels;

Architecture refers to the entity part that constructs the style and image of the object by separating, combining, decorating and modifying the inner and outer space of the load-bearing structure;

Water refers to building water supply and drainage engineering, which is a branch of water supply and drainage engineering and also a branch of building installation engineering. It mainly studies the water supply and drainage problems in buildings to ensure the function and safety of buildings. Mainly divided into: building water supply system, building drainage system (including rainwater, sewage and wastewater), fire hydrant water supply system, automatic sprinkler system, landscape system, hot water system, reclaimed water system and so on. (For example, pipes, sanitary wares and appliances that provide water supply for houses, pipes and appliances that discharge sewage and waste water, fire hydrants and fire sprinklers are rare in your common water supply and drainage projects);

Electricity is customarily divided into strong electricity (electricity) and weak electricity (information). Strong electricity projects mainly include: residential electricity, power electricity, commercial electricity, landscape lighting electricity, office electricity and so on. General 380/220V V weak current projects include: TV project, communication project, fire protection project, security project, video project, etc. And the integrated wiring project for the above projects. (such as power equipment, cables and electrical appliances (high voltage) that provide lighting, power distribution, power generation and elevator power for houses, as well as intelligent system equipment, cables and electrical appliances such as television, telephone, broadband, monitoring and fire fighting);

HVAC is the abbreviation of HVAC engineering, including heating engineering, ventilation engineering and air conditioning engineering.

For example, the structure you ask here is like the skeleton of the human body; Buildings are like meat, clothes, decorations, etc. On people; Hydropower is like blood and heart; HVAC is like skin (including skin pores and hair) and subcutaneous fat, which is responsible for ventilation and heat dissipation.

Taking Beijing Water Cube as an example, the structure refers to the steel frame structure of foundation, column, beam, shear wall and roof; Architecture, including the shape of the water cube and the decorative effect of the facade, also includes indoor brick walls and partitions, as well as other decorative partitions, ceilings, floors and so on. , as well as outdoor decorative curtain walls and decorative plates; Water refers to indoor and outdoor cold and hot water pipes, drainage pipes, rainwater pipes, water meters, valves, faucets, washstands and basins, toilets, fire hydrant pipes, automatic sprinkler pipes, feed pumps, drainage pumps, fire pumps, etc. Electricity refers to power distribution cabinets, generators, transformers, wires and cables, trunking, bridges, conduits, switches, sockets, lamps and lanterns, as well as access control, simultaneous interpretation, electronic display screens, intelligent management, monitoring, television, telephone, broadband, fire alarm, etc.

Heating and ventilation, including heating, such as radiators in northern shopping malls and schools, supporting pipes for conveying hot water to radiators, boilers for providing hot water, etc. Ventilation, including air supply, exhaust and smoke exhaust, for example, the largest square pipe under the basement roof of a shopping mall is the pipe for ventilation and fire smoke exhaust, and of course there is a fan in the computer room in the system; Air conditioning refers to air conditioning. The air conditioning unit (located in the machine room) heats or cools the water, and the water is transported through the pipeline and flows through the coil copper pipe (under the ceiling) of the fan coil. When air comes into contact with a copper tube, it becomes cold or hot. The fan coil is driven by electricity, and the cooled air is sent to the required place through the air inlet of the input air duct, which plays a role in regulating the air there (of course, another group of fans pass through other independent air inlets and air ducts in the room).
