Application of water curtain air conditioning

A five-star hotel adopts the pool with an artificial waterfall to improve the indoor thermal environment. Analyses and compares the improving effect of different temperature chilled water from 10 ℃ to 16 ℃ in the pool on the indoor thermal environment in the three conditions of natural ventilation under thermal pressure, fan and air conditioning running at night, and air conditioning. The results show that using fan and low temperature chilled water in the pool can meet occupants’ thermal comfort requirement in part of the hotel without running air conditioning units. Suggests that the temperature of chilled water in the pool is set at 10 ℃, the air conditioning units run in the day, and that the fans run in some areas and air conditioning units run in the rest at night to realize energy saving.
