5. Introduction to High-rise Air Conditioning and Fire Protection:
High-rise: Refers to tall buildings, typically residential structures with 18 floors or more. Individuals in high-ranking official positions or with high social status have historically been considered part of the upper echelon. The term is also used to describe atmospheric layers with greater altitude and more floors.
Central Air Conditioning: The central air conditioning system comprises one or more hot and cold source systems and multiple air conditioning systems. Unlike traditional refrigerant-based air conditioning (such as standalone units, VRV), this system centrally processes air to meet comfort requirements. It utilizes the principle of liquid vaporization refrigeration to provide the required cooling for air conditioning systems, offsetting indoor environmental heat loads. The heating system provides the required heat to offset indoor temperature loads.
The refrigeration system is a crucial component of the central air conditioning system, and its type, operation mode, and structural form directly affect the system’s economy, efficiency, and rationality during operation.
Ice Storage Cooling System: During periods of lower electricity demand and favorable electricity prices, the system uses electric refrigeration to produce ice in the main air conditioning unit. The ice is stored in ice storage equipment. During periods of higher electricity demand during the day, avoiding peak electricity prices, the electric refrigeration unit is either stopped or operated intermittently. This releases the stored cooling capacity from the ice storage equipment to meet the building’s air conditioning load.
Fire Protection: “Fire protection” involves eliminating hazards, preventing disasters (referring to the general term for preventing and solving man-made and natural, accidental disasters encountered by people in the process of life, work, and study). In the early stages of human understanding, the narrow meaning was to extinguish fires.
It mainly includes personnel rescue at the fire scene, rescue of important facilities, equipment, cultural relics, security protection, and salvage of important property, as well as firefighting. The goal is to reduce the extent of damage caused by fires, minimize casualties, and prevent property losses. During wartime, it is unified and commanded by the various levels of people’s air defense command, with professional firefighting forces as the backbone, mobilizing the firefighting teams of enterprises, institutions, towns, volunteer teams, and the general public.
Firefighting actions mainly include:
1) Investigating the fire situation and damage, understanding the terrain, wind direction at the fire scene, the structure and entrances/exits of the burning building, and the situation of trapped individuals.
2) Implementing on-site command, organizing forces to quickly reach the fire scene, selecting firefighting agents and equipment based on the nature of the fire, and correctly applying firefighting tactics based on the fire scene. Key methods include preventing the spread of fire, establishing firebreaks, blocking fire paths, extinguishing remaining embers, and guarding the fire scene.
3) Quickly rescuing trapped individuals and transferring and transporting injured individuals.
4) Timely evacuating or isolating dangerous items near the fire scene to prevent secondary disasters. Firefighting uses water and chemical extinguishing agents, employing equipment such as firefighting vehicles, fire extinguishers, and mobile water pumps to implement firefighting. Adhering to the principles of prioritizing lives over property, controlling before extinguishing, and ensuring key actions.
