An air sampling fire detection system including a heat exchanger capable of preventing condensation and freezing

摘要

The present invention relates to a cold storage air inhalation type fire detection system capable of preventing condensation and freezing. More specifically, a system for detecting a fire in a cold storage comprises: an air inhalation type fire detector installed outside the cold storage, and detecting the fire by introducing the air in the cold storage; an inhalation pipe provided between the cold storage and the fire detector, and introducing the air in the cold storage to the fire detector side; and a heat exchanger provided on one side of the inhalation pipe, and heating the air introduced to the fire detector.
