Hollow fiber membrane dehumidifier and humidity control device having the same

Provided in the present invention are a hollow fiber membrane dehumidifier and a humidity control device having the same. In particular, a dehumidifier which has a dehumidifying hollow fiber membrane, which removes moisture from the air, as a main component, and a humidifier which has a humidifying hollow fiber membrane, which supplies moisture to the air, as a main component, are connected in parallel to control the amount of moisture in the air. Water mist is not generated at the hollow fiber membrane humidifier to achieve the perfect humidification. Aseptic humidification can be performed to solve the problem of conventional humidifier disinfectants. Therefore, a humidifier with excellent efficiency can be provided to perform instantaneous humidification. Hot water is not required to be generated for humidification, such that an additional energy (electricity) is not used to provide hot water. The humidification by using the hollow fiber membrane, unlike the humidifier in the refrigerating compression method, does not generate heat during the dehumidification process, such that the indoor temperature is not increased even during the lengthy dehumidifying operation. High-pressure air generated by a compressor and the like is not required, which reduces electricity consumption, thereby increasing energy efficiency compared to the conventional dehumidification method using a refrigerant. Humidification by using the hollow fiber membrane allows only the moisture, absorbed into the hollow fiber membrane, to be contained in the air. Consequently, impurities existing in the humidifying water can be prevented from being scattered in the air along with water particles, thereby providing clean humidified air. In addition, moisture particles in the gaseous state, passing through the hollow fiber membrane, are very small, in order to significantly widen the scattering range in the air, thereby preventing dew from condensing around an outlet of the humidified air. To this end, the present invention comprises: a dehumidifying housing; a hollow fiber membrane; an air inlet; an air outlet; a sweep air supply unit; and a sweep air discharge unit. 본 발명은 공기의 수분을 제거하는 제습용 중공사막 멤브레인을 주 구성요소로 하는 제습기와 공기에 수분을 공급하는 가습용 중공사막 멤브레인을 주 구성요소로 하는 가습기를 병렬로 연결하여 공기의 습도를 조절하여, 중공사막 가습기에서는 수적(water mist)이 발생되지 않으므로 완벽한 가습이 가능하고, 무균 가습이 가능(기존의 가습기 살균제 문제 해결)하며, 순간적인 가습이 가능한 매우 효율이 높은 가습기를 제공할 수 있고, 가습을 위해 일부러 열수를 만들어야 할 필요가 없어, 온수를 제공하기 위한 별도의 에너지(전기)가 사용되지 않으며, 중공사막 멤브레인을 이용한 제습은 냉동압축방식
