The present invention relates to an adaptive flow control method for controlling the indoor temperature of an air conditioning system, and a device thereof. According to the present invention, based on data such as the building's indoor temperature, outdoor temperature, and circulating water intake temperature, by actively controlling the flow rate of circulating water flowing into an air conditioner and heater such as fan coil units (FCU), in the case of a complex heat source system in which, in addition to a main heat source such as circulating water flowing between a heat pump and the air conditioner and heater, auxiliary heat sources flowing within a solar or geothermal system are used together, as the circulating water intake flow rate can be customized according to the indoor temperature, the dependence on auxiliary heat sources required for indoor temperature control is lowered, deriving the effect of increasing energy efficiency and system economic feasibility. 본 발명은 공조 시스템의 실내온도 제어를 위한 적응형 유량제어 방법 및 장치에 관한 것으로, 건물의 실내온도, 실외온도, 순환수 입수온도와 같은 데이터를 기초로 팬 코일 유닛(FCU)과 같은 냉난방기에 유입되는 순환수 입수유량을 능동적으로 제어함으로써, 히트펌프와 냉난방기 사이에서 유동하는 순환수와 같은 메인열원 이외에도 태양열이나 지열 시스템 내에서 유동하는 보조열원이 함께 활용되는 복합열원 시스템의 경우 실내온도에 따라 맞춤형으로 순환수 입수유량을 선정할 수 있게 됨에 따라, 결국 실내온도 제어를 위해 요구되는 보조열원 의존도를 낮춰 에너지 효율 및 시스템 경제성을 높일 수 있게 하는 효과를 도출한다.
