Weak current is used as the connection, monitoring, broadcasting and network of communication equipment.

Each booth should build a collecting well, and the main drainage ditch of the shopping mall should plan a maintenance well, so as to drain water layer by layer and arrange maintenance layer by layer.
3. HVAC system: Compared with strong and weak electricity systems and water supply and drainage systems, HVAC system is bigger, because not all farmers' markets use HVAC system. HVAC system is the general name of air conditioning, fresh air system and smoke exhaust system. The smoke exhaust system belongs to the category of fire protection planning and reconstruction, and it is not necessary to consider whether natural smoke exhaust meets the requirements.
