In terms of transfer functions a model has been established for dynamic modulation characters of air conditioning terminal systems.Its input function is the outdoor temperature while a responding indoor temperature is obtained as its output.Based on these mathematical descriptions variable flow systems can be controlled.The software SIMULINK has been applied to analyze the modulation process.According to these studies further analyses can be carried out on modulation characters of the variable flow water systems.
