Abstract

PURPOSE: A hybrid desiccant dehumidifier and a control method thereof are provided to reduce the energy consumed for cooling or regeneration by using the condensation heat of a freezer as the desiccant dehumidification source. CONSTITUTION: A hybrid desiccant dehumidifier comprises a first exterior air conduction line(1), an evaporator(V), a compressor(P), a condenser(C), an expansion valve(E), a desiccant rotor regenerating unit, a regeneration air conduction line(L1), a regeneration exhaust line(L3), an air supply line(L2), a dehumidification space(T), and a controller. The desiccant rotor regenerating unit eliminates the moisture from the exterior air frozen by the evaporator and heats the exterior air. The regeneration air conduction line heats the exterior air introduced from a second exterior air conduction line(2) connected to the condenser and supplies it to the desiccant rotor regenerating unit. The regeneration exhaust line collects and discharges the high temperature and high humidity regeneration air. The air supply line supplies the processed air to the dehumidification space. The dehumidification space maintains the internal temperature and humidity. The controller controls cooling or dehumidification and temperature rise of the introduced exterior air according to the exterior temperature and humidity condition.

본 발명은 하이브리드 데시칸트 제습 장치 및 그 제어방법에 관한 것으로, 더욱 상세하게는 환기를 재사용할 수 없는 선박도장과 같은 열악한 환경에 적용되는 외기공조기에 관한 것이며, 증발기를 이용하여 외기를 프리쿨링 후 이를 데시칸트제습기를 지나게 하여 제습 및 가온시키는 한편, 냉동기 응축기의 응축열을 이용하여 가열된 재생공기를 데시칸트제습기의 재생열원으로 공급하여 데시칸트로터를 열교환에 의해 탈착한 고온다습한 재생공기를 외부로 배기시킬 수 있도록 하여, 냉동기와 데시칸트제습기를 하나의 장치으로 병합시킴으로서 장치를 보다 콤팩트화하고 운전비를 대폭으로 절감할 수 있도록 한 하이브리드 데시칸트 제습 장치 및 그 제어방법에 관한 것이다.The present invention relates to a hybrid desiccant dehumidifying apparatus and a control method thereof, and more particularly, to an outdoor air conditioner applied to a harsh environment such as a ship coating in which ventilation cannot be reused, and after precooling the outside air using an evaporator. The dehumidifier is passed through a desiccant dehumidifier and dehumidified and warmed, while the regenerated heat of the refrigerator condenser is supplied to the regeneration heat source of the desiccant dehumidifier to supply the desiccant rotor to the outside of the hot and humid regenerated air by heat exchange. The present invention relates to a hybrid desiccant dehumidifier and a control method thereof, by which a refrigerator and desiccant dehumidifier are combined into a single device, thereby making the device more compact and significantly reducing operating costs.
종래 공조(냉방 및 제습)는 에어컨에 의한 방식이 일반적이다. 에어컨의 구조를 간단히 설명하면, 실내기와 실외기 사이에 냉매(상변화에 따라 열을 운반하는 물질)를 순환시켜 낮은 온도의 실내 측으로부터 높은 온도의 외기 측으로 열을 방출하는 장치이다. Conventional air conditioning (cooling and dehumidification) is generally by air conditioning. Briefly, the structure of the air conditioner is a device that circulates a refrigerant (a material that carries heat according to a phase change) between an indoor unit and an outdoor unit to release heat from a low temperature indoor side to a high temperature outdoor air side.
냉매는 실내기 내에서 실내의 공기로부터 열을 빼앗아 증발하고, 실외기로 이동한다. The refrigerant takes heat from the indoor air in the indoor unit, evaporates it, and moves to the outdoor unit.
실외기에 있는 압축기에 의해 냉매가 압축되고 외기로 냉각 응축되어 열을 외기로 방출한다. 증발열을 빼앗김으로써 실내의 공기는 냉각되어 냉방이 가능하게 된다.The refrigerant is compressed by the compressor in the outdoor unit and cooled and condensed to the outside to release heat to the outside. By removing the heat of evaporation, the air in the room is cooled and cooled.
제습의 경우에는 실내공기 중에 포함되어 있는 수증기가 응결하는 온도까지 냉각되어 공기와 수분을 분리한다. In the case of dehumidification, the water contained in the indoor air is cooled to a temperature where the water vapor condenses to separate air and moisture.
일반적으로 응결온도는 공조에 적당한 온도보다 낮아 과도하게 냉각된 공기를 그대로 실내에 공급하는 것은 쾌적성을 해칠 우려가 있어 적당하지 않다. In general, the condensation temperature is lower than the temperature suitable for the air conditioning is not suitable to supply excessively cooled air to the room as it may damage the comfort.
그러므로 냉각된 공기를 재가열하는 등 적절한 온도로 조절하여 실내에 공급한다.Therefore, the cooled air is supplied to the room by adjusting to an appropriate temperature such as reheating.
이와 같이 종래의 공조방식에서는 온도제어만 하는 수단이었지만 습도제어도 실현할 필요가 있어짐에 따라 냉각-재가열 이라는 조작이 필요하게 되었다.As described above, in the conventional air conditioning system, only the temperature control is used, but as the humidity control needs to be realized, an operation of cooling and reheating is required.
최근 가정용 에어컨은 재가열을 위해 종래는 외부에 방출되던 응축열의 일부를 실내기 측에서 이용하는 방식도 개발되어 있지만 덕트공조 장치에서는 별도의 가열을 위한 열원을 필요로 한다.Recently, home air conditioners have been developed to use a part of the condensation heat that has been released to the outside in the indoor unit for reheating, but the duct air conditioner requires a heat source for separate heating.
한편 선박도장과 같은 열악한 환경이나 위험한 물질을 취급하는 작업장과 같이 환기 공기를 재이용할 수 없는 현장에서는 통상의 공조 장치을 적용할 수 없는 문제점이 있었다.
또한 환기를 재이용할 수 없으므로 온도 및 습도를 적정하게 맞추기 위해 냉방 및 제습장치를 더 많이 가동하여야 하므로 이로 인해 에너지 소모가 증가되는 문제점이 있다.
On the other hand, there is a problem that can not be applied to the normal air conditioning equipment on the site that can not reuse the ventilation air, such as in the harsh environment, such as ship coating or the workplace handling dangerous substances.
In addition, since the ventilation can not be reused, more cooling and dehumidification apparatuses must be operated to properly adjust temperature and humidity, thereby increasing energy consumption.
본 발명은 상기한 종래 기술의 문제점을 해소하기 위해 안출된 것으로, 선박도장과 같은 열악한 환경에 적용되는 외기공조기에 관한 것이며, 공랭식 냉동기의 냉각(증발기)을 이용하여 외기를 전단냉각(프리쿨링) 후 이를 데시칸트제습기를 지나게 하여 제습 및 가온시키는 한편, 냉동기 응축기의 응축열을 이용하여 가열된 공기를 데시칸트제습기의 재생열원으로 공급하여 상기 냉각된 외기를 열교환에 의해 처리부는 제습 및 가온이 되고 재생부는 재생(탈습)시킬 수 있도록 한, 냉동기와 데시칸트제습기를 하나의 장치으로 병합시킴으로서 장치를 보다 콤팩트화하고 운전비를 대폭으로 절감할 수 있도록 한 하이브리드 데시칸트제습 장치 및 그 제어방법을 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems of the prior art, and relates to an outdoor air conditioner applied to a harsh environment, such as ship coating, shear cooling (precooling) the outside air using the cooling (evaporator) of the air-cooled freezer After passing through the desiccant dehumidifier, it is dehumidified and warmed, while the heated air is supplied to the regenerated heat source of the desiccant dehumidifier by using the heat of condenser of the freezer condenser, and the treated part is dehumidified and warmed and regenerated by heat exchange. The Department provides a hybrid desiccant dehumidifier and a control method thereof by combining the refrigerator and desiccant dehumidifier into a single device, which enables regeneration (dehumidification), to make the device more compact and to significantly reduce operating costs. There is a purpose.
