In consideration of safety, the system load of an air conditioning system is usually excessively large in design. As a result, the capacity of energy transmission and distribution equipment of the system (e.g. fan) and the terminal heat exchanger drastically exceed actual needs. Systematic strategy can be used for optimizing fan coil system.

• The optimal energy-efficiency Control system adjusts the volume of air supply to control the humidity and temperature within air conditioned areas. When the load in air conditioned area is lower than design load, the controls can supply less air volume to the system in order to save the system operation energy consumption.
• In addition to reducing operation energy consumption, the control system optimizes the temperature difference of AC air supply to satisfy occupant’s comfort.
• CO2 detector is used to control supply volume of outdoor fresh air. Based on the hygiene requirements, fresh air shall be minimized in summer and winter, and maximized (even to full fresh air) during transitional seasons according to outdoor air conditions.
