51、指室空调负荷全部由水来负担。 系统适用性： 1、建筑空间小，不宜于布置风道； 2、不需通风换气的场所。 三、空气-水系统是指室空调负荷由空气和水共同负担。 1、室温、湿度要求一般的场合； 2、层高较低的场合； 3、冷负荷较小、湿负荷也较小的场所。 四、冷剂式系统是指空调房间负荷由制冷剂直接承担。 1、空调房间布置分散； 2、要求灵活控制空调使用时间；3、无法集中设置冷热源。全空气一次回风系统的空调机组送风量是恒定的，系统的夏季冷量由室冷负荷、新风负荷和再热负荷组成，对于送风温差无严格要求的舒适性空调，如采用大温差送风即露点送风的一次回风系统，可不需要消耗再热量，因此可节省能耗。但送风温差过大，

52、往往会造成送风口解霜现象，为避免此类现象的发生，采用一次回风空调系统需利用再热来解决送风温差受限制的问题，即为了保证必须的送风温差，一次回风系统在夏季需要再热，从而产生冷热抵消的现象风机盘管加新风系统是空气-水系统的一种主要形式，也是我国民用建筑中采用最普遍的一种空调方式，它的投资少，使用灵活和节省建筑空间等优点被广泛应用于各类建筑中。该系统具有以下特点：本设计为培训中心，通过对上述空调系统的分析，本设计采用空气-水系统。新风系统的形式采用分楼层水平式，每层设置新风系统，采用风机盘管加新风系统，新风处理方式不一样，对室空气品质有很大的影响。风机盘管加新风系统的空气处理方式有：（1）新风处理到室

53、状态的等焓线，不承担室负荷；（2）新风处理到低于室空气的焓值，并低于室空气的含湿量，承担部分室负荷。这里选用不承担室冷负荷方案，在每层的空调机房处设置一新风处理机组，负担新风负荷，新风不与风机盘管回风混合，新风口单独送风。水系统表 STYLEREF 1 s 4.SEQ 表 * ARABIC s 11系统方案比较类型特征优点缺点闭式管路系统不与大气相接触，仅在系统最高点设置膨胀水箱。设备腐蚀小，不需克服静水压力，水泵压力，功率低，系统简单。与蓄热水池连接较复杂。开式管路系统与大气相通。与蓄热水池连接较简单。易腐蚀，输送能耗大。同程式供回水干管中的水流方向一样，经过每一管路的长度基本相等。水量分配

54、，调度方便，便于水力平衡。需设回程管，管道长度增加，初投资稍高。续表类型特征优点缺点异程式供回水干管中的水流方向相反，经过每一管路的长度不相等。不需设回程管，管道长度较短，管路简单，初投资稍低。水量分配，调度较难，水力平衡较麻烦。两管制供热，供冷合用同一管路系统。管路系统简单，初投资省。无法同时满足供热和供冷的要求。三管制分别设置供冷、供热管路与换热器，但冷热回水的管路共用。能同时满足供冷、供热的要求，管路系统较四管制简单。有冷热混合损失，投资高于两管制，管路系统布置较简单。四管制供冷、供热的供、回水管均分开设置，具有冷、热两套独立的系统。能灵活实现同时供冷或供热，没有冷、热混合损失。管路系统

55、复杂，初投资高，占用建筑空间较多。单式泵冷、热源侧与负荷侧合用一组循环水泵。系统简单，初投资省。不能调节水泵流量，难以节省输送能耗，不能适应供水分区压降较悬殊的情况。变水量系统中的供回水温度保持定值，负荷变化时，通过改变供水量的变化来适应。输送能耗随负荷的减少而降低；配管设计，可以考虑同时使用系数，管径相应减少；水泵容量、电耗相应的减少。系统复杂；必须配备自控设备。底层停车场通风量风量计算本设计采用全面通风方式，可得： （公式 STYLEREF 1 s 4.SEQ （公式 * ARABIC s 11）式中：n 换气次数，制冷机房、水泵房排风量推荐换气次数为4-6次/h，此处换气次数取5次/h机
