공조시스템 단위기기 제어알고리즘의 통합

The efficient operation of a HVAC system is recommanded to save the energy consumption at a building. The effective control of a HVAC system was considered as one of the near-term energy saving solutions. To minimize difficulties to develop various unit control algorithm and to avoid their related tuning problems, an unified unit control algorithm was proposed. This algorithm was developed based on the fuzzy logic which used the control error, its first and second derivatives as input variables. In order to verify the control performance, the initial start-up test and the step change test were performed. Test showed good results for the control of various units of a HVAC system.
