Selection should be based on fan coil fan coil can provide sensible and total heat required for room cooling load can meet the sensible and total heat load of the principle of selection.
Between public health and other toilet room shall be provided mechanical ventilation device, generally set exhaust fan, bathroom ventilation volume by 20-30. Bathroom without windows must set air vents, exhaust duct from the same ground out by the exhaust fan to the outside row. Close to the wall and there is a bathroom outside the window directly outside.
Noise is loud and noisy or strident is not needed for a particular job or interfere with the sound.
Waves in gases, liquids and solids in the transmission. Noise is a sound wave, which has all the characteristics of sound waves. Frequency and intensity of different sounds together irregularly become noise.
The noise inside the building was mainly due to setting air conditioning, plumbing, electrical equipment produced after which the noise generated by air-conditioning equipment greatest impact. Air conditioning engineering major noise source is the fan, refrigerator, mechanical draft cooling tower.
To prolong the life of the heating system, heating system pipes to prevent corrosion of equipment, it needs to be anti-corrosion treatment process.

绪论
地球上本没有建筑,人类创造了建筑;地球上本没有城市,人类构建了城市。建筑扩大了人类的生存低于,延长了人类的个体寿命;城市增强了人类的交流合作,加快了人类社会的发展。建筑和城市是人类最伟大的工程创造,彰显着人类文明进步的历史。建筑和城市的出现,将原来单纯统一的地球环境分割为三个不同的层次。第一层次为自然环境,其性状和变化由自然力量决定;第二层次为城市环境,其性状和变化由自然力量和人类行为共同决定;第三层次为建筑环境,其性状和变化由人类行为决定。
由于城市物质文化活动的高效益,人们越来越多的聚集于城市。发达国家的城市人口已达全国人口的70%左右;中国正在加快城市化进程,实际上的城市人口很快就将超过50%。现代社会,人类大多数活动在建筑内开展。城市居民一生中约有90%的时间在建筑环境中度过。为了提高生产水平,保护生态环境,包括农业在内的现代生产过程也越来越多地从自然环境转移进建筑环境。建筑环境已成为现代人类社会生存发展的重要空间。 四星级酒店中央空调系统设计+CAD图纸(3):http://www.751com.cn/gongcheng/lunwen_8024.html
