摘要：
This paper presents a design scheme of composite air conditioning control system. The air conditioning control system comprises an water chiller, evaporative cooling fresh air unit and dry fan coil (inlet water temperature 18 degrees C). The water chiller comprises an evaporative cooling water chiller and a mechanical refrigeration water chiller (air- source heat pump). The Johnson distributed control system is used to control the air conditioning system. Control scheme include outlet water temperature control of water chiller, inlet water temperature control of dry fan coil (inlet water temperature 18 degrees C), outlet air temperature control of evaporative cooling fresh air unit and auxiliary heat source control.
