Application of energy flow chart on air conditioning system design for clean operating departments

The energy consumption of air conditioning system in operating rooms is higher than that of other zones in a hospital because of higher indoor environment requirement. In order to simplify energy consumption analysis, puts forward a new technical economical evaluation index, i.e. energy cost effectiveness (ECE) of air conditioning, which is used as an auxiliary analysis tool combined with an energy flow chart. With the energy flow chart and the ECE index, analyses the influence of building layout, air change rate, fan pressure head and air handling process on the energy consumption of air conditioning system for clean operating departments. Suggests that the method be used to make necessary comparison and perform technical and economic analysis for the energy consumption of air conditioning schemes at design phase.
