Reviews the different methods for the coolingdevicesand water distribution system simulation. Describes the simulation models and methods suitable forthe building energy consumption simulation, in the DeST program for the cooling/heating plant and waterdistribution system. Also explainshow to do the cooling/heating plant and water distribution system full yearsimulation in the DeST program with an example.Keywordsnull cooling/heating plant, water distribution system, ful-lyear simulationnull Tsinghua University, Beijing, China0nulldbd,%d?pp,g1s,9?h1sbH31GLdbyN?aaVLbd!9,P?Mx,iO?pp,Bbd!91TbYVS=30E,K,vK9b!9ZEi/K:a)E!#da,M/?!91b!9Z!91pbL=H,i=yHWM,!vsHW!9/,7s/byNVn,E!,vsHWTrT,9E!9eZT?dM1bb)E!M?fbG!9|,9?EV!M?,yN!9ZEEM?s,V7E!9Z6b7,!#!M/?1M?#dZN1Ib!9iK,4ZEM?f,4ZG,9E!9ZbyN1dZMHEsbdZEs,ZHEs,!9ZrT(?b)!H1p()()?bEXHq:a)b)!H1p()();b)dZT#5s,=Q,d;c)ZT,T+QV;d)X!,M1-,-;e)X!,s/T?;f)!eZT,eZTe,g,bdZHEs,V/ET:a)!da,?b)!H1p()(),iqf;b)5H;c)!Harq?;d),Harq?bYVET,Vb#!9ZM?f,V7VZ44VLGbnull43nullnull null null null null null null null 暖通空调 HV&ACnull 2005年第 35卷第4期 null null null null5VsXWDeSTEq!#EsZEb/s|dME9ZEbn5e1-dZEC,W%DeSTdZEEZE,iLb1nulldEC,bdaa,FeZTs,t+dE4bBZ,1aaeZTbd8yiadpdv4,-B?KblbdE,E$5vdEb6BZ5,BYTebeT+min,Y/aarE,1 hHWMeVEV?QLb7evH(7qaH(aH(EE,5|dn,7L=dC?Eb6,5,Yef/,|5+TMd+s,|s/Mvb7L?C,f/5dMlbVtf/,8+8+
