The present invention relates to an energy saving required for the development of a low-cost, high-efficiency, and field supply type plant factory production system and, more specifically, to a control method of an energy saving heat pump thermo-hygrostat for plant factory, which overcomes disadvantages of low energy efficiency due to low airflow uniformity, low CO2 concentration, inadequate humidity control in an early stages of operation, and high level of heating and cooling loads required to provide an optimal plant growth environment of conventional general air conditioner type air conditioner. 본 발명은 저비용·고효율 현장보급형 식물공장 생산시스템 개발을 위하여 요구되는 공조 장치로서, 종래의 일반적인 스탠드 에어컨 타입의 공조 장치가 가진 낮은 기류 균일도, 낮은 CO농도, 운전 초기의 습도 관리 미흡, 최적의 식물 생육 환경을 제공하기 위하여 요구되는 높은 수준의 냉난방 부하로 인한 낮은 에너지 효율의 단점을 극복할 수 있는 에너지 절감형 식물공장 전용 히트펌프 항온항습기 및 그 제어 방법에 관한 것이다.
