이에 의하면, 환절기의 주간에 시설하우스의 온도가 상승할 때에는 열매체저장부(310)에 저장된 저온의 열매체를 순환시킴으로써 시설하우스에 냉방이 이루어지게 하되, 열매체저장부(310)에 축열이 이루어지게 할 수 있으며,In this case, when the temperature of the facility house rises in the daytime of the season, the low-temperature heat medium stored in the heat medium storage unit 310 is circulated to cool the facility house, and heat storage is performed in the heat medium storage unit 310 And,

환절기의 야간에 시설하우스의 온도가 하강할 때에는 주간에 축열된 고온의 열매체를 순환시킴으로써 시설하우스에 난방이 이루어지게 할 수 있다.
When the temperature of the facility house falls in the nighttime of the season, the heating house can be heated by circulating the high-temperature heat medium that has been stored during the daytime.

결국, 상기와 같은 구성으로 이루어진 본 발명에 의한 제습 기능이 구비된 냉난방장치에 의하면,As a result, according to the air conditioning apparatus having the dehumidifying function according to the present invention,

냉방모드, 난방모드, 제습모드 및 축열모드의 운전이 가능하되, 각 운전모드의 변경 시 격리되는 냉매가 발생하지 않게 됨으로써 장치가 안정적으로 운전될 수 있으며, 열매체순환파트(300)의 펌프(320)를 가동하는 것만으로 열매체를 이용한 냉난방모드 및 축열모드의 운전이 가능함으로써 장치의 운전비가 절감될 수 있다.
It is possible to operate the cooling mode, the heating mode, the dehumidification mode, and the heat storage mode. However, since the refrigerant isolated during the change of each operation mode is not generated, the apparatus can be operated stably, It is possible to operate the heating / cooling mode and the heat storage mode using the heating medium, so that the operation ratio of the apparatus can be reduced.
