150平的空间需要多大的精密空调，制冷量是如何计算的？150平的空间需要多大的精密空调，制冷量是如何计算的？

关于算法:面积x-450(根据机房实际情况)/860=制冷量150x/860=70，不小于70可以考虑大余量点可以把换成450。

机房精密空调功率选择根据机房内设备的热值计算信息机房的专用精密空调的制冷量怎样计算？具体有几部分组成？一般是估算还是精确计算。

专用空调房间不同于一般空调，房间空调是全天候工作的，另外，房间空调主要是除去“感热”。计算机机房空调一定要精确，尤其是机房结构，如果不按照空调机房的特殊结构进行施工，制冷量的计算应更加仔细，应首先根据当地平均温度等参数，室外环境进行传热计算，这是关键，然后计算室内设备包括照明、发热等，要考虑新风引入时的热损失，计算室内总热量，将数据放大到一定冗余，选择制冷主机。

150平的空间需要多大的精密空调，制冷量是如何计算的？一般家庭每平米需要的制冷量为120W - 150W，如果是顶层干燥或西干，每平米的制冷量需要相应增加。在单层建筑中中国房间290 ~ 350W /m2[250 ~ 300kcal/h?m2]在多层建筑中房间175 ~ 290W /m2[150 ~ 250kcal/h?m2]在绝大多数房间(设备发热一般)，不准确的计算机房热量的设备,精密空调的选择可以直接根据标准设计的290 ~ 350 w / m2, 0.29 - -0.35千瓦/ m2(等于250 ~ 300千卡/ h?m2),为了安全,在大多数情况下,根据标准的0.35千瓦/ m2(即300千卡/ h?m2)。简单的办法，1
