Description

초절전형 냉방기 { a power saving air conditioner }Ultra low power air conditioner {a power saving air conditioner}

본 발명은 초절전형 냉방기에 관한 것으로, 더욱 상세하게는 복수의 냉각부를 조합시킴으로써 열교환 효율을 향상시킬 수 있어 적은 냉동용량으로도 큰 냉방능력을 얻을 수 있게 한 초절전형 냉방기에 관한 것이다.The present invention relates to an ultra low-power type air conditioner, and more particularly, to an ultra-low power type air conditioner that can improve heat exchange efficiency by combining a plurality of cooling parts, thereby obtaining a large cooling capacity even with a small freezing capacity.

일반적으로 전화국의 교환실이나 전자계산실과 같은 전산장비가 구비된 전산실은 기기장치에서 다량의 열이 발생되어 항상 실내온도가 높아지는데, 이를 냉각시켜 주지 않으면 과열에 의해 기기장치의 오동작이 발생될 우려가 있어 별도의 냉방기를 이용해 실내온도를 적정 온도로 유지해야 한다.In general, computer room equipped with computer equipment such as telephone exchange center or electronic computing room generates a large amount of heat from the device and always raises the room temperature.If it is not cooled, overheating may cause the device to malfunction. Therefore, a separate air conditioner should be used to maintain the room temperature at an appropriate temperature.

따라서 대부분의 전산실에는 에어컨이나 항온항습기와 같은 냉방기를 설치하여 실내온도를 적정하게 냉각시키고 있다.Therefore, most computer rooms are equipped with air conditioners such as air conditioners and thermo-hygrostats to properly cool the room temperature.

상기 냉방기의 냉동사이클을 살펴보면, 압축기에서 고온,고압으로 압축된 냉매가 응축기에서 중온,고압으로 응축되고, 건조기에서 건조된 후 팽창장치를 통과하면서 팽창되어 증발기로 보내지며, 팽창과 동시에 압력과 온도가 낮아진 냉매는 증발기에서 열을 흡수하게 되고, 열을 흡수하면서 기체가 되어 다시 압축기로 보내지면 1회의 순환을 완료하게 되는 것이다.Looking at the refrigeration cycle of the air conditioner, the refrigerant compressed to a high temperature, high pressure in the compressor is condensed to medium temperature, high pressure in the condenser, dried in the dryer and then expanded while passing through the expansion device is sent to the evaporator, at the same time the pressure and temperature Lower refrigerant absorbs heat from the evaporator, becomes a gas while absorbing heat, and is sent back to the compressor to complete one cycle.

이때 상기 압축기와 응축기, 실외기홴(Fan)은 대개 실외기 내부에 설치되며, 상기 증발기 및 팽창장치, 실내기 홴은 실내기 내부에 설치되는 것이다.At this time, the compressor, the condenser, and the outdoor unit (Fan) are usually installed inside the outdoor unit, and the evaporator, the expansion device, and the indoor unit (F) are installed inside the indoor unit.

따라서 상기 증발기에 흐르는 저온의 냉매와 실내공기가 열교환됨으로써 냉방이 이루어지는 것이다.Therefore, cooling is achieved by heat exchange between the low temperature refrigerant flowing through the evaporator and the indoor air.

그런데 종래의 냉방기는 실내면적이 클수록 이에 비례하여 증발기의 크기를 크게해야 하고 아울러 압축기, 응축기, 팽창장치의 크기도 크게 제작해야 하므로 제조비용과 설치비용이 상승하게 되는 문제점이 있었다.However, the conventional air conditioner has to increase the size of the evaporator in proportion to the larger indoor area, and also to increase the size of the compressor, the condenser, and the expansion device, thereby increasing the manufacturing cost and the installation cost.

또한 실외기를 외부에 따로 설치해야 하므로 별도의 설치비용이 증가되는 문제점이 있으며, 특히 냉방기의 냉동용량이 클수록 전력소모량이 증가되므로 유지비용이 상승하게 되는 문제점이 있었다.In addition, since the outdoor unit must be installed separately from the outside, there is a problem in that a separate installation cost is increased, and in particular, as the refrigeration capacity of the air conditioner is increased, the power consumption increases, so that the maintenance cost increases.

본 발명은 상기 종래 기술의 문제점을 해소하기 위해 안출된 것으로, 냉동사이클이 이루어지는 제1 및 제2 냉각부를 복수로 조합시킴으로써 다중의 열교환에 의해 실내공기가 냉각되게 하여 냉동효율을 극대화시킬 수 있는 초절전형 냉방기를 제공하는 데 첫번째 목적이 있다.The present invention has been made in order to solve the problems of the prior art, by combining a plurality of first and second cooling unit of the refrigeration cycle to allow the indoor air to be cooled by a plurality of heat exchanger ultra-power saving can maximize the refrigeration efficiency The first purpose is to provide a type air conditioner.

또한 본 발명은 제1 냉각부를 소형으로 제작함으로써 별도의 실외기가 없이도 냉매의 압축 및 응축이 가능하도록 하여 제작비용과 설치비용을 절감시킬 수 있고, 전력소모량도 절감시킬 수 있는 초절전형 냉방기를 제공하는 데 두번째 목적이 있다.In another aspect, the present invention provides a super-cooling type air conditioner that can reduce the production cost and installation cost by reducing the production cost and installation cost by enabling the compression and condensation of the refrigerant without a separate outdoor unit by making the first cooling unit to a small size There is a second purpose.

이때 상기 증발기(42)는 도 3에 도시된 바와 같이, 이중관 구조로 하여 내측관(45)에는 상기 제1냉각부(2)의 제1냉매가 흐르도록 하고, 외측관(43)에는 상기 제2냉각부(4)의 제2냉매가 흐르도록 하여 제1냉매와 제2냉매간에 열교환이 이루어지게 하였다.In this case, as shown in FIG. 3, the evaporator 42 has a double tube structure such that the first refrigerant of the first cooling unit 2 flows through the inner tube 45, and the first tube is provided in the outer tube 43.
