摘要
Abstract
An experimental system for a chilled beam air conditioning system combining an active chilled beam with an air ejector was designed.An experimen-tal method was adopted to investigate the influence of fresh air parameters on the cooling effect and perfor-mance of the chilled beam air conditioning system.The standard experimental conditions are as follows:com-pressed air supply temperature of 25℃,supply pres-sure of 0.7 MPa,supply flow rate of 9.08 m3/h,chilled beam chilled water inlet temperature of 17℃,and mass flow rate of 0.11 t/h.The influence of fresh air temperature on the cooling performance of the chilled beam air conditioning system is much greater than that of fresh air flow rate.Reducing the fresh air tempera-ture can significantly improve the indoor cooling effect,whereas simply increasing the fresh air flow rate has a limited effect.On the premise of meeting the necessary fresh air demand of the room,using fresh air at typical summer outdoor temperatures(30-35℃)can achieve satisfactory performance of the chilled beam air condi-tioning system.When the fresh air temperature was constant,an excessively high fresh air flow rate is not recommended.Obvious spatial differences exist in the vertical temperature distribution in the room cooled by the chilled beam.The vertical temperature distribution is more complex closer to the chilled beam,and becomes closer to the traditional thermal stratification farther away from it.关键词
