the  central  air  conditioning  main  engine,  the  auxiliary  engine  movement  operating mode change, the gathering temperature, the pressure and so on the many kinds of coefficient of variation,  then  through  the  load  move  computation,  the  change  system  freezing  water  current capacity,  the  cooling  water  current  capacity  and  the  cooling  tower  air  blower  amount  of  wind adapts  the  air  conditioning  load  change,  simultaneously  causes  the  main  engine  movement operating mode throughout to be in optimized in the best operating point. Generally when full load pumping machine needs  the  full speed movement, has not  conserved energy  the space, but uses the  redundant  technology  and  the  frequency  conversion  technology  unifies,  the  proportioning pump  and  the  variable  displacement  pump  coordinate,it  is  the  truths.To  freezes  the  aqueous system to use the best output energy control. When the ambient temperature, the air conditioning terminal  load  changes, Optimized  the main  engine movement  pattern  each  group  freezing water for the backwater temperature, the temperature difference, the differential pressure and the current capacity also along with it change, these parameters which the flowmeter, the differential-pressure pickup  and  the  temperature  sensor  examines  delivers  to  the  intelligent  controller,  the  real-time data and the system historyperformance data which the controller basis gathers, the real-time idea figures  out  the  refrigeration quantity which  the  terminal  air  conditioning  load  needs,  as well  as each  group  freezing  water  for  the  backwater  temperature,  the  temperature  difference,  the differential  pressure  and  the  current  capacity  best  value,  and  to  this  adjusts  various  frequency changers output  frequency,  the  control  freezes  the water pump  the  rotational  speed, Changes  its current  capacity  to  cause  the  freezing  aqueous  system  for  the  backwater  temperature,  the temperature difference,  the differential pressure and  the  current capacity movement  the optimum value which produces  in  the controller.Because  the  freezing aqueous system has used  the output energy  dynamic  control,  the  realization  air  conditioning  host  frozen    intermediary  current capacity follows the terminal load the demand supply, causes the air-conditioning system in each kind of load situation, all can both guarantee terminal user's comfortableness, and maximum limit has  saved  the  system  energy  consumption.The  cooling  water  system  uses  the  best  hot  transfer efficiency  control.  The  cooling  water  and  the  cooling  tower  air  blower  system  uses  the  best transfer  efficiency  control. When  the  ambient  temperature,  the  air  conditioning  terminal  load changes,  central  air  conditioning  main  engine  load  factor  along  with  it  change,  main  engine condenser best hot transformation temperature also along with it change. The intelligent controller basis  gathers  the  real-time  data  and  the  system  history  performance  data,  calculates  the  main engine  condenser  the best hot  transformation  temperature  (inflection  point  temperature)  and  the cooling water  is best,  the  inlet  temperature,  and by  this  adjustment  cooling water pump  and  the cooling tower air blower frequency changer output frequency, the control cooling water pump and the  cooling  tower  air  blower  rotational  speed,  the  dynamic  adjustment  cooling  water  current capacity and the cooling  tower air blower amount of wind, causes the cooling water to enter, the outlet  temperature approaches  the optimum value which  the  intelligent controller produces,  thus guaranteed  the  central  air  conditioning  main  engine  is  at  under  the  best  transfer  efficiency condition to move as necessary. Because  the  cooling water  system  uses  the  best  transfer  efficiency  control,  had  guaranteed  the central air conditioning main engine in the full load and in the partial load situation, is at the best active  status,  throughout  maintains  the  best  energy  use  factor  (namely  the  COP  value),  thus reduced the air conditioning main engine energy consumption, simultaneously because the cooling water pump and the cooling tower air blower frequently in are lower than under the fixed load to move, also maximum limit saved the cooling water pump and the cooling tower air blower energy consumption. 空调节能技术英文文献和中文翻译(6):http://www.751com.cn/fanyi/lunwen_31576.html
