The refrigerant chemical oxygen respirator of the room temperature phase-change material comprises a mask, an oxygen-producing purifier, a balloon, a cooling machine, a battery, global position system (GPS) controller, and the like. Gas gets into the oxygen-producing purifier through the mask and a respiratory tube in the process of working. Carbon dioxide inside the oxygen-producing purifier reacts with drug to produce oxygen, and the oxygen enters into the balloon to be stored in the exhaling process. In the inhaling process, after the gas flowing out from the balloon is cooled through the cooling machine, the gas enters into the mask through the respiratory tube for people to breathe. The cooling machine utilizes the room temperature phase-change material to conduct a phase-change cooling to cool. The refrigerant chemical oxygen respirator of the room temperature phase-change material overcomes the shortcoming that a traditional respirator is not convenient to use because the traditional respirator needs to utilize electricity or ice to cool. Meanwhile, the refrigerant chemical oxygen respirator of the room temperature phase-change material has the advantages of being simple in structure, convenient to use and supply.
