大型中央空调节能策略

Industry & Commercial Air Conditioning system Energy Saving Planning.

根据绿色节能规范，对每个冷冻及制热系统因地制宜的进行节能设计和改造。

Based on Green eco-energy code,we should design or change the existing heating & air conditioning system in each  local conditions.

①冷却塔  Cooling Tower

提高换热效率  Promote heat efficiency

减少漂水率  Reduce feed water

提高进水温度  Higher supply temperature

CTI认证  CTI approval

②水泵组  Pumps

提高水泵效率  Promote pump effciency 

变频控制  Frequency control

大温差  High temp. difference

减少流量和扬程  Less waterflow and head

③空调机组  Air Conditioning unit

大温差减少风机能耗  Higher diff. temp to reduce fan’s power.

CO2控制减少新风能耗  Fresh air control by CO2 sensor. 

季节性节能全新风控制  Seasonal eco-energy full fresh air control 

风机变频  Fan’s Variable control

④末端系统  Terminal air system

变风量系统  Variable Air Volume System

避免过冷过热能耗损失  Avoid over cooling & heating

提升舒适度  Promote comfortable enviroment

⑤系统控制  Control system

智能化优化运行管理  Intelligent optimal operation management

远程监控  Remote Monitoring system

⑥冷冻机组  Chiller  

提高能效  Promote energy effiency

螺杆式  Screw  COP>5.5

离心式  Centrifugal  COP>6.1 

一次泵变流量  Chiller pump variable flow

热水回收系统/免费取冷技术  Heat recovery/economizer

⑦水蓄冷/冰蓄冷  Water/ICE Thermal Storage

利用电价差，白天放冷夜间制冷

To store cooling load at lower Elec. cost time. (Night & day time)
