본 발명은 냉방기에 관한 것으로서, 보다 구체적으로는 실외기 기능을 실내기 내에서 이루어지게 함으로 해서 설치의 간편성, 도심미관 및 도시온도 상승의 문제점 해소, 냉방 효율 극대화를 제공하는 실외기 없는 냉방기를 제공코자 한 것이다.The present invention relates to an air conditioner, and more particularly, to provide an outdoor unit air conditioner that provides an outdoor unit function within an indoor unit to solve the problems of ease of installation, urban aesthetics and city temperature rise, and maximize cooling efficiency. .

일반적으로 널리 사용되는 냉방기는 냉매가 기체 또는 액체가 되는 과정을 끊임없이 반복할 수 있도록 냉매를 증발시키는 증발기와, 증발된 기체 냉매를 액체로 환원하는 압축기와, 압축된 냉매에서 발생하는 열을 배출하는 응축기와, 응축된 액체 냉매를 증발기에 기체 상태로 공급하는 팽창밸브로 구성된다.In general, a widely used air conditioner is an evaporator for evaporating a refrigerant so that the refrigerant can be repeatedly gas or liquid, a compressor for reducing the evaporated gas refrigerant into a liquid, and a heat discharger from the compressed refrigerant. And an expansion valve for supplying the condensed liquid refrigerant in a gaseous state to the evaporator.

이러한 메커니즘으로 구성되는 종래 냉방기는 실내기와 실외기로 대분 구성되며, 실내기에는 증발기와 증발기 후방에 설치되는 송풍팬 및 팽창밸브가 설치되고, 실외기에는 응축기와 응축기 후방에 설치되는 송풍팬 및 압축기가 설치된다.The conventional air conditioner composed of such a mechanism is mainly composed of an indoor unit and an outdoor unit, and an indoor unit is provided with a blowing fan and an expansion valve installed at the rear of the evaporator and an evaporator, and an outdoor unit is equipped with a blowing fan and a compressor installed at the rear of the condenser and the condenser. .

상기 증발기 및 응축기의 경우 각각 팽창밸브 및 압축기와 연결 구성되는 가는 동 파이프를 지그재그로 절곡하고 그 표면에 방열핀을 설치한 것을 복수로 설치하여 열 교환이 이루어지게 하고, 이들 각각의 동 파이프를 압축기와 팽창밸브에 연결한 구성으로 각각의 동 파이프로 이동하는 냉매의 압력조건을 동일하게 제공하기가 어려워 냉방효율을 극대화시킬 수 없는 단점이 있었고, 특히 증발기로 냉매를 공급하는 팽창밸브의 경우 냉매의 정체 현상 등으로 인해 동결되어 냉방기 가동이 정지되는 문제점도 있었다.In the case of the evaporator and the condenser, each of the thin copper pipes connected to the expansion valve and the compressor is zigzag-folded, and a plurality of heat radiating fins are installed on the surface of the evaporator and the condenser so that heat exchange is performed. It is difficult to maximize the cooling efficiency because it is difficult to provide the same pressure condition of the refrigerant moving to each copper pipe with the configuration connected to the expansion valve. Especially, in the case of the expansion valve that supplies the refrigerant to the evaporator, the stagnation of the refrigerant Due to the phenomenon, there was a problem in that the air conditioner was stopped due to freezing.

또한 상기한 구성으로 냉방기를 구성할 경우 설치작업이 어렵고 실내기와 실외기 간을 배관 연결해야 하는 바, 많은 량의 냉매를 필요로 하게 되며 그로 인해 실외기가 커지게 되는 등 설치에 많은 어려움이 있었으며, 실외기로 인한 도심미관 훼손 및 소음공해, 열기로 인해 주변 온도가 상승하게 되는 등 다수의 문제점이 있었다. In addition, when the air conditioner is configured with the above configuration, the installation work is difficult and the pipe connection between the indoor unit and the outdoor unit requires a large amount of refrigerant, which causes the outdoor unit to be large. There are a number of problems, such as damage to the city's aesthetics, noise pollution, and ambient temperature due to heat.

이에 본 발명자는 실외기 기능을 실내기 내에서 이루어지게 한 냉방기를 구성하여 설치의 간편성, 도심미관 및 도시온도 상승의 문제점 해소, 냉방효율의 극대화를 제공할 수 있는 실외기 없는 냉방기를 제공함에 발명의 기술적 과제를 두고 본 발명을 완성한 것이다.Accordingly, the present invention provides an air conditioner without an outdoor unit that can provide the outdoor unit function in the indoor unit to solve the problems of ease of installation, urban beauty and city temperature rise, maximization of cooling efficiency by configuring the air conditioner in the indoor unit. The present invention has been completed.

상기 기술적 과제를 해결하기 위해서는 먼저 압축기로 압축된 액상의 냉매에서 발생하는 열을 방열하여 냉각하는 응축기의 열 교환을 실내에서 행하면서도 냉방 효율을 유지하여야 하는바, 본 발명에서는 냉방기 본체 내측으로 트랙형의 밀폐공간을 형성하고 그 내부에 응축기 및 응축기를 냉각할 수 있는 냉각수단을 설치함으로 해서 실외기 없이 냉방기 작동이 이루어질 수 있게 하였다.In order to solve the above technical problem, the heat exchange of the condenser that radiates and cools the heat generated by the refrigerant in the liquid phase compressed by the compressor must be maintained indoors while maintaining the cooling efficiency. By forming a confined space of the condenser and a cooling means for cooling the condenser and the condenser therein, it is possible to operate the air conditioner without an outdoor unit.

그리고 본 발명에서는 냉방 효율을 극대화할 수 있도록 하기 위해 수단으로 팽창밸브 및 압축기에 배관 연결되는 증발기 및 응축기 구성을 적극적으로 개량하여 냉매의 순환주기를 빠르게 하면서도 신속한 열 교환이 가능하게 하였다.In the present invention, by actively improving the evaporator and condenser configuration connected to the expansion valve and the compressor as a means to maximize the cooling efficiency, it is possible to quickly heat exchange while circulating the refrigerant cycle.

본 발명은 냉매를 기체 상태로 공급하는 팽창밸브와, 팽창밸브에 연결되어 냉매를 증발시키는 증발기 및 증발기에 연결된 압축기가 내장 설치된 냉방기 본체를 구성함에 있어서, 압축기에서 압축된 냉매에서 열을 방열하는 응축기 및 응축기를 냉각하는 냉각수단을 더 부가한 것이다.The present invention comprises an expansion valve for supplying a refrigerant in a gas state, an evaporator connected to the expansion valve to evaporate the refrigerant, and a cooler main body provided with a compressor connected to the evaporator, wherein the condenser radiates heat from the refrigerant compressed by the compressor. And cooling means for cooling the condenser.
