1）风机盘管的送风口、回风口和送风管、回风管布置：一台风机盘管一般设一个送风口；送、回风口距离超过7m但小于10m时，可一台风机盘管设两个送风口；超过10m时宜设两排及以上风机盘管。一台风机盘管一般设一个回风口。送风管就是风机盘管与送风口的连接管。回风管就是风机盘管与回风口的连接管（有的习题风机盘管带回风口，也就带了回风管）。风机盘管的送风口与回风口不在同一水平面时（如送风口为上侧送、回风口为上回），送风口与回风口距离可相对近一些。风机盘管的送风口与回风口在同一水平面时（如送风口为上侧送、回风口为上侧回；送风口为上送、回风口为上回等），送风口与回风口不宜太近，尽量远一些。送风口中心距墙不宜小于1m，因送风口一般为散流器，从风口向斜下方吹的气流遇到墙后向下，会使向下的气流过大。

1) the air outlet of the fan coil, the return air port and the air duct, the return duct arrangement: a fan coil is usually set up to give a mouth; A fan coil shall be set up by two air lines at less than 10 megabytes. More than 10 megabytes have two rows and above fan coil. A fan coil usually has a return port. Air pipe is the connection pipe between the fan coil and the outlet port. The back duct is the connection pipe of the fan coil and the backwind. (some of the problem fan coil is brought back to the vents, and the wind tube is brought back.) Fan coil air diffuser and return air mouth isn't in the same horizontal plane, such as air supply outlet as upper send and return air mouth as last time), air diffuser and return air mouth distance can be relatively close to. Fan coil air diffuser and return air mouth at the same horizontal plane (such as air supply outlet send, return air mouth as the upper back; for upper air supply outlet for beam, return air mouth for the last time, etc.), air diffuser and return air mouth shoulds not be too close, far away as far as possible. The center distance of air supply outlet wall should not be less than 1 m, normally because of air supply outlet diffuser, blowing air from beneath the tuyere syncline down after you run into a wall, can make the down the flow of air is too large. 

　2）新风口、排风口和新风管、排风管布置:为使室内维持一定的新鲜空气量，要根据人员多少、停留时间、污染程度等因素把室外空气经过加热、冷却、加湿、过滤等处理后单独送入房间。习题对新风管的连接有要求时，如：新风接风机盘管入口、新风接风机盘管出（送）风管等，按题目的要求布置；题目无要求时，新风单独接风口。新风送入房间后经过人的呼吸不再新鲜，要排出房间以使新风再进入。

2) fresh air outlet and the mouth and fresh air tube, exhaust duct layout: to make the fresh air in the interior to maintain a certain amount, according to how much, residence time, factors such as the pollution level of outdoor air after heating, cooling, humidifying and filtering after processing into separate rooms. When the problem sets are required for the connection of the new wind pipe, such as: the inlet of the new wind fan coil, the coil of the new wind fan, and the wind tube, etc., to be arranged in accordance with the requirements of the subject; When the title is not required, the new wind will be alone. The new wind comes into the room and the breath is no longer fresh, and the room is expelled to allow the new wind to enter.
