Description

물을 열매체로 이용한 하이브리드형 냉난방기Hybrid air conditioner using water as a heating medium
본 발명은 물을 열매체로 이용한 하이브리드형 냉난방기에 관한 것으로, 보다 상세하게는 실내기와 실외기 사이에 물을 순환시켜 냉방을 공급함과 동시에 냉방작동과는 구분된 보일러 구조에 의해 난방을 공급할 수 있도록 된 물을 열매체로 이용한 하이브리드형 냉난방기에 관한 것이다.The present invention relates to a hybrid air conditioner using water as a heat medium, and more particularly, to supply cooling by circulating water between an indoor unit and an outdoor unit, and at the same time to supply heating by a boiler structure separate from the cooling operation. It relates to a hybrid type air conditioner using as a heat medium.
일반적으로 에어컨이나 보일러 또는 온풍기와 같이 냉방이나 난방을 공급하도록 된 냉난방기는 대개 실내기와 실외기를 냉매라인으로 연결하여 냉매에 의해 열을 흡수 또는 방출하는 열교환을 통해 실내에 냉방이나 난방을 공급하는 것으로, 장치에 따라서는 냉방과 난방을 선택적으로 공급할 수 있도록 냉매라인 상에 냉매의 흐름을 절환할 수 있는 삼방 또는 사방밸브 등을 구비하여 정역사이클에 의해 냉방과 난방작동을 선택적으로 교번시킬 수 있도록 구성된 것이다.In general, an air conditioner to supply cooling or heating, such as an air conditioner, boiler, or heater, connects an indoor unit and an outdoor unit with a refrigerant line to supply cooling or heating to a room through heat exchange in which heat is absorbed or released by a refrigerant, Depending on the device, a three-way or four-way valve that can switch the flow of refrigerant on the refrigerant line is provided so that cooling and heating can be selectively supplied, so that cooling and heating operations can be selectively alternated by forward and reverse cycles. .
그런데, 통상적인 냉난방기에서는 프레온가스와 같은 냉매를 열매체로 사용하여 열교환이 이루어지고, 이러한 냉매가 순환되는 냉매라인은 동파이프를 단열재로 감싼 상태로 실내기와 실외기를 연결하도록 연장하는데, 이와 같은 냉매라인은 사용자가 원하는 위치에 실내기를 설치하거나 설치장소를 이동시키는 데에 번거로움이 클 뿐만 아니라 부식 등에 의한 유지보수의 번거로움이 따르는 것이다.However, in a typical air conditioner, heat exchange is performed using a refrigerant such as Freon gas as a heat medium, and the refrigerant line through which the refrigerant circulates is extended to connect the indoor unit and the outdoor unit while the copper pipe is wrapped with an insulator. Such a refrigerant line In this case, it is not only cumbersome to install the indoor unit at a location desired by the user or to move the installation location, but also inconvenient maintenance due to corrosion.
또한 종래의 냉난방기는 전술된 바와 같은 냉매라인 등으로 인해 장치의 전체적인 설치나 이동 등이 불편할 뿐만 아니라 동절기에 실외기 측에 적상되어 이를 제거하기 위한 제상작업에 의해 장치의 난방효율 저하되거나 난방공급의 제한 또는 지연의 문제점이 발생될 수 있고, 이로 인해 종래에는 보조보일러를 가동하여 실내온도를 유지함에 따른 장치의 추가설치나 비용의 부담이 발생될 수 있는 것이다.In addition, conventional air conditioners are not only inconvenient to install or move as a whole due to the refrigerant lines as described above, but also to reduce the heating efficiency of the device or limit the heating supply by defrosting work to remove them from the outdoor unit side during the winter season. Alternatively, a problem of delay may occur, and due to this, additional installation of a device or a burden of cost may occur due to conventionally operating an auxiliary boiler to maintain room temperature.
특히 비닐하우스와 같이 농작물을 재배하는 공간 등에서 설치 사용하는 경우에는 냉난방기의 잦은 고장이나 효율저하로 인해 작물의 생장이나 고사 등과 같은 피해가 발생될 수 있다는 점에서 그 중요도가 매우 큰 데, 종래의 냉난방기에 의해서는 전술된 바와 같은 장치의 설치나 효율저하 등의 문제점이 발생될 수 있다는 점에서 개선의 여지가 큰 것이다.In particular, in the case of installation and use in a space where crops are grown, such as a plastic greenhouse, it is very important in that damage such as crop growth or death may occur due to frequent breakdowns or efficiency reduction of the air conditioner. Conventional air conditioners There is a great room for improvement in that problems such as installation of the above-described device or reduction in efficiency may occur.
본 발명은 전술한 바와 같은 문제점을 해결하기 위한 것으로, 본 발명은 간단한 배관구조에 의해 실내기와 실외기 사이에 물을 순환시켜 냉방을 공급함에 따라 장치의 설치나 이동 등의 편리함을 제공하고, 냉방구성과는 별도로 된 간단한 보일러 구조에 의해 난방을 공급하여 동절기의 난방효율을 개선할 수 있도록 된 물을 열매체로 이용한 하이브리드형 냉난방기를 제공하는 것이다.The present invention has been made to solve the above-mentioned problems, and the present invention provides convenience such as installation or movement of a device by circulating water between an indoor unit and an outdoor unit through a simple piping structure to supply cooling, and provides a cooling configuration.
