"When the construction materials are burned, it can go up to 500 degrees celsius. This means that the temperature inside the burning room could be anywhere from 300 to 500 degrees celsius. With such a high temperature, it would be impossible to put it out with normal water. This is why using dry powder would be a better alternative. However, with these sprinklers, it can quickly lower the temperature of the water, turning it into a fluid that is still in a liquid state at negative 20 degrees celsius. If it was in a normal situation, the water would immediately turn into ice as soon as it was released from the sprinklers. but with such a temperature inside the room, it would only turn into water. This is why the huge fire from just now could be put out so rapidly. It is because of the water at that temperature."
Zhan Lichuan's explanation caused another huge round of applause.
