注：①用各分类指标M分别乘以建筑中相应类型房间的空调面积N （顶层房间M值宜加大20-25％），然后全都相加所得总和就是建筑物的空调系统负荷。

考虑各类房间的同期
使用率等情况，将系统负荷乘以0.84-0.86的修正系数，计算得制冷机组总安装容量即可计算出空调系统总负荷的概算值，即Q＝（0.84-0.86）M×N
用分类指标乘相应类型房间每间的面积，得各房间的空调负荷，这就是选择房间末端空气处理设备的参考数值.
②对于空气一水系统（风机盘管）. 办公楼所需最小新风量可按4.60～7.20m3/h.m2选用.
旅馆卧室
单人房 0.80～1.20m3/h.m2
双人房 1.20～2.00m3/h.m2
③剧场、电影院观众厅最小新风量可按7～lOm3/（h.人）选用，电影放映机的排风量按下值选用：7OO m3/（h.台）（弧光灯）；600 m3/（h.3KW）（氙灯）；800 m3/（h.5KW）（氙灯）
④一般的民用建筑不考虑新风
换气负荷。

对于某些高级民用建筑，其中一些房间要求保证一定的通风量，以满足卫生换气的需要。

当卫生要求的换气量小于渗透风量时，可以不再计算卫生要求通风量。

当卫生要求的换气量大于渗透风量时，要设专门的送排风系统，要计算通风换气增加的空调负荷。

客房出风量 =新风量 / (0.8-0.9)系数。

④一般的民用建筑不考虑新风
换气负荷。

对于某些高级民用建筑，其中一些房间要求保证一定的通风量，以满足卫生换气的需要。

当卫生要求的换气量小于渗透风量时，可以不再计算卫生要求通风量。

当卫生要求的换气量大于渗透风量时，要设专门的送排风系统，要计算通风换气增加的空调负荷。

客房出风量 =新风量 / 系数。

半集中式中央空调系统设备冷负荷分配方式的探讨王　靖,李晓虹摘　要:　讨论了在夏季半集中式中央空调系统(风机盘管加独立新风系统)干湿工况中,风机盘管和新风机组在承担冷负荷上的不同形式,并指出了风机盘管和新风机组承担不同负荷分配的计算方法。

以及各设备在承担不同负荷时,负荷计算在设备选型时的作用。

关键词:　负荷;风机盘管;新风系统;设备选型;湿工况 中图分类号:TU83116;O551;O414文献标识码:B 中央空调系统中,运用风机盘管加独立新风系统较为常见,在设备选型设计中如何合理选择风机盘管和新风机组的大小是设计人员普遍关心的问题。

在相同的室内、室外参数的条件下,总热、湿负荷分别由室内风机盘管和新风机组共同承担,但是室内风机盘管和新风机组所承担的负荷(包括热负荷和湿负荷)的大小,因负荷分配上存在着不同的形式,所以其承担负荷的大小是可以变化的。

并且室内风机盘管和新风机组承担负荷的大小决定了其设备的大小,所以如何将总冷负荷分配给室内风机盘管和新风机组,其负荷计算就显得非常重要,否则将给设计选型带来困难,最终使设计方案达不到最满意的效果。

下面作者就其负荷分配形式和设备选型中的几个问题进行分析。

1　风机盘管加独立新风系统的机组冷负荷组成风机盘管加独立新风系统的机组总冷负荷等于室内负荷、新风负荷、再加热负荷之和,并由室内风机盘管和新风机组共同承担;其相互关系如图1所示。

从下面的几种焓湿图的分析中可以看出,风机盘管加独立新风系统中的各参数,只有室外设计参数W 、室内设计参数N 、新风量G w 是确定值,而室内热湿比线ε、机器露点L 1、L ′1、L 2、L ′2等,将随着风机盘管和新风机组承担负荷的不同,以及回风量的大小的变化而位置发生改变。

如果以室内热湿比线ε确定室内送风状态点,将会出现因风机盘管、新风机组承担负荷的变化而使室内热湿比线ε难以确定的矛盾。

所以作者拟采用先确定新风机组的负荷,再确定热湿比线ε的方法绘制空调过程的焓湿图。

一般设计的空气工况：（广州，数据有微调）
干球温度湿球温度相对湿度比焓（kJ/kg）
新风工况35 28 60 91
24 18 55 51
回风工况（室内状
态）
送风工况14 12 80 34
新风冷负荷：（90-34）*1.2*1000/3600=18.7≈20KW
回风冷负荷：（51-34）*1.2*1000/3600=5.7≈5KW
新风的冷负荷：偏大估算：冷量=风量*20（冷量单位是千瓦，风量单位是千方）
回风的冷负荷：偏大估算：冷量=风量*5（冷量单位是千瓦，风量单位是千方）
前表冷器主要是负责处理新风的。

所以：偏大估算：冷量=风量*20
后表冷器主要是负责处理新风+回风的。

所以：偏大估算：冷量=风量*5
但是因为转轮除湿机的很大一部分（约60%）的再生热量在除湿过程转换为被处理空气的冷负荷，所以要加上这一部分冷负荷。
