To study the impact of introducing low-temperature chilled water from ice storage air conditioning into a radiant air conditioning system on the internal temperature of a refuge chamber, a three-dimensional model of the refuge chamber was established, and the FLUENT software was used to simulate the effects of parameters such as the position of ice storage-radiant air conditioning, surface temperature, and wall temperature on the temperature field of the refuge chamber. The results show that the ice storage-radiant air conditioning system can help reduce indoor temperature, and the lower the surface temperature of the radiant panel, the greater the cooling effect; the closer the outer surface of the radiant panel on the ice storage-radiant air conditioning system is to a square, the better the cooling effect; the wall temperature has little effect on the cooling effect of the ice storage-radiant air conditioning system; the best effect is achieved when the ice storage-radiant air conditioning is located in the center between the indoor and the wall.
