Heptafluoropropane overview and scope of application

1. System introduction
Heptafluoropropane (HFC-227ea) is a clean gas extinguishing agent that extinguishes chemically. It is colorless, odorless, low-toxic, non-conductive, and does not pollute the protected object. In particular, it has no destructive effect on the atmospheric ozone layer and has an ODP value of zero. It meets environmental protection requirements and is an ideal substitute for halon fire extinguishing agents at this stage. The fire extinguishing agent has high fire extinguishing efficiency, high speed and no secondary pollution.
The QM series consists of storage bottles, liquid check valves, high pressure hoses, headers, selection valves, pipe networks, sprinklers and automatic fire extinguishing controllers. The storage pressure of the system at 20 ° C is 4.2 MPa and the maximum working pressure (At 50 ° C) is 5.3MPa,
2.Fire extinguishing agent characteristics
1) It is a colorless and odorless gas. Its ozone depletion potential (ODP) is 0, which meets environmental protection requirements and is an ideal substitute for halon fire extinguishing agents.
2) Physical and chemical fire extinguishing is a new type of high-efficiency and low-toxic fire extinguishing agent. It has a low fire extinguishing concentration, a small amount of steel cylinders and a small space;
3) Heptafluoropropane fire extinguishing agent is non-conductive, does not contain water, and will not cause damage to electrical equipment, tapes, materials, etc .;
4) The minimum design concentration is 7.35% (V / V);
5) The highest concentration of non-toxic reaction (NOAEL) is 9% (V / V), which can be used in the human area.
3. Applicable occasions
1) Can extinguish various types of fires A, B, and C, and can be used safely and effectively in people's places;
2) After the medicine is sprayed, it is required to leave no traces or difficult places to clean the residue;
3) The protected area contains valuables, priceless treasures, precious files, software and hardware, etc .;
4) Particularly suitable for: telecommunications main control room, airport control room, bank vault, archives, library, computer room and other occasions.
4. Not suitable for occasions
1) In the case of chemical substances that can be rapidly oxidized without air, such as nitrocellulose and black powder;
2) Storage and production sites of active metals-potassium, sodium, magnesium, titanium, and uranium;
3) Storage place for metal hydride.

Pipe network heptafluoropropane system composition and technical parameters

七氟丙烷 自动灭火系统组成 1. Composition of heptafluoropropane automatic fire extinguishing system

自动灭火系统 火灾报警系统、灭火控制系统和灭火装置三大部分组成,灭火装置 灭火储存装置及管网系统两部分组成。 Heptafluoropropane automatic fire extinguishing system consists of three parts: fire alarm system, fire control system and fire extinguishing device .

七氟丙烷 自动灭火系统分类 2. Classification of Heptafluoropropane Automatic Fire Extinguishing System

自动灭火系统为全淹没灭火系统。 1) The heptafluoropropane automatic fire extinguishing system is a fully submerged fire extinguishing system. 保护区 空间内任 一点火灾的一套装置 A fully submerged fire extinguishing system is a set of devices that can extinguish a fire in any point in the protected area space .

全淹没灭火系统分类 2) Classification of fully submerged fire suppression systems

合分配系统、无管网灭火系统。 According to the number of protected areas, it is divided into unit independent systems, combined distribution systems, and pipeless fire suppression systems.

管网 灭火系统。 The unit independent system refers to a pipe network fire extinguishing system that protects a protective area with a set of fire extinguishing agent storage devices .

二个或二个以上 防护区的 管网 灭火系统。 The combined distribution system refers to a pipe network fire extinguishing system that protects two or more protective areas with a set of fire extinguishing agent storage devices . The combined distribution system is mainly composed of three parts: fire alarm control, fire control and fire extinguishing device.

Pipeless network fire extinguishing system is also called prefabricated system. For details, see later in this chapter.
