Abstract

Highly effective aerosol fire-extinguishing agent (HEAE) is a safe and practical alternative to Halon which developed from pyrotechnics. When HEAE starts up, it generates aerosol products with high temperature so that its temperature must be lowered to not harmful to person and material. Aerosol products are cooled with exterior cooling by use of chemical coolant. This article mainly discussed the influences of refrigerant contents, apertures, proportion of refrigerant on the spout temperature of HEAE.
