随着人民生活水平的提高,对建筑的舒适性要求也越来越高。中央空调在二、三线城市公共建筑中的使用也越来越普遍。直燃机作为一种高效、节能的冷热源设备,在暖通空调设计中选用也增多。多数直燃机房设在建筑单体的地下室中,设备噪声与振动的消除就尤为重要。本文主要分析直燃机房噪声与振动产生的原因及消除的途径。 With the improvement of people’s living standards, the requirements for the comfort of buildings are also getting higher and higher. Central air-conditioning in the second and third tier cities in the use of public buildings is also more and more common. Direct combustion engine as a high-efficiency, energy-efficient cold and heat source equipment, HVAC design also increased. Most direct engine room is located in the basement of a single building, equipment noise and vibration elimination is particularly important. This paper mainly analyzes the causes of noise and vibration in direct combustion engine room and ways to eliminate them.
