Abstract

Abstract: Temperature and humidity distribution of curing rooms which are mainly used in the production line of concrete component factory are studied by simulation. Considering high temperature and high humidity in the curing room, wall condensation and mist condensation are used to simulate the condensation in the room. The simulation results show that the relative humidity of most areas reaches 100% very fast, but the temperature distribution is extremely uneven and temperature difference is up to 26℃. In addition, by changing the nozzle orientation, position and quantity, it is found that the temperature is more uniform when the nozzle is downward; when the nozzle is located in 46% to 65% of the total height of the room, the temperature distribution achieves the best uniformity; the increase in the number of nozzles can improve the temperature distribution between the nozzles.

Key words: curing rooms of concrete, temperature and humidity distribution, numerical simulation, condensation simulation, optimization analysis
