Classification of kitchen fire extinguishing equipment pipe network:
Water distribution network: Pipes that send water to the distribution network and the user.
Annular pipe network: An arrangement of the water distribution pipe network. The pipes are connected to each other vertically and horizontally to form a ring.
Branch pipe network: an arrangement form of water distribution pipe network, the main and branch pipes are distinct,
Pipe network characteristic curve: Under different circumstances, the refrigeration and air-conditioning pipe network has different pipe network characteristic curves.
The characteristic curve of the pipe network is the H-W curve representing the relationship between the water flow W in the pipe network and the pressure loss H of the pipe network.
