它是矿井通风动力和风流网络体的组合。通风系统形式是指矿井进风井与周风井的布置形式，可以分为对角式和混合式。通风方式是指主要通风机的工作方式，可以分为压入式、抽出式以及混合式。通风方法就是指获取力量的通风动力，有自然通风和机械通风两种。通风网路就是指风道的联接形式，有串联、并联和角联三种。

It is a combination of mine ventilation power and air flow network. The form of ventilation system refers to the layout of mine air intake shaft and peripheral air shaft, which can be divided into diagonal type and hybrid type. Ventilation mode refers to the working mode of the main fan, which can be divided into press in type, draw out type and mixed type. Ventilation method refers to the ventilation power to obtain power, including natural ventilation and mechanical ventilation. Ventilation network refers to the connection form of air duct, including series, parallel and angular connection.

水管安装。水管安装要严格执行国家规范，冷冻水主干管及冷却水管吊架要采用弹簧减振吊架，而且吊架不能固定在楼板上，应尽量固定在梁上，或在梁与梁之间架设槽钢横梁固定。水管穿过楼板或过墙采用套管，且套管与水管之间要用阻燃材料填封。 风系统安装。风管制作安装要严格按照国家规范进行施工，在风机进出口安装阻抗消声器，新风进口处采用消声百叶，风管适当部位设置消声器

Water pipe installation. Water pipes shall be installed in strict accordance with national specifications. Spring damping hangers shall be used for the main chilled water pipes and cooling water pipes, and the hangers shall not be fixed on the floor, but shall be fixed on the beam as far as possible, or channel steel beams shall be erected between beams for fixation. When the water pipe passes through the floor or wall, the casing shall be used, and the fire-retardant material shall be filled between the casing and the water pipe. Installation of air system. The fabrication and installation of air duct shall be carried out in strict accordance with national specifications. Impedance muffler shall be installed at the inlet and outlet of fan, silencing shutter shall be used at the inlet of fresh air, and muffler shall be set at appropriate parts of air duct

五星酒店对暖通的要求集中体现在：系统运行的可靠性要高；室内的舒服度要高；系统要实现节能运行。设需要注意以下几方面的问题：不同的酒店管理集团有不同的设计标准，例如某酒店的室内空调设计标准：五星酒店客房的夏季、冬季设计温度分别为24℃、22℃，其它房间的室内设计标准也都比较高，负荷计算时应按照酒店管理集团的标准进行（往往设计院认为不满足设计规范要求，但对于五星酒店审图不会卡这个）。

The requirements of five-star hotel for HVAC are mainly reflected in: the reliability of system operation should be high; Indoor comfort should be high; The system shall realize energy-saving operation. Attention should be paid to the following aspects during design: different hotel management groups have different design standards, such as the indoor air conditioning design standards of a hotel: the design temperatures of five-star hotel rooms in summer and winter are 24 ℃ and 22 ℃ respectively, and the indoor design standards of other rooms are also relatively high. The load calculation should be carried out in accordance with the standards of the hotel management group (the design institute often thinks that it does not meet the requirements of design specifications, but it will not be stuck for the drawing review of five-star hotel).
