Abstract
본 발명의 목적은 난방시 주위 온도가 과부하 조건일때 온도와 압력이 상승하게되는 실내열교환기 및 실외열교환기의 온도와 압력을 낮추어 해결할 수 있는데, 이를 위해 실내열교환기에는 온도감지센서를 부착하고 압축기 토출부에는 상기 온도감지센서에 의해 동작하는 3방변을 연결하되 1측은 실외열교환기 하단을 지나 실내열교환기에 연결되도록 하고 다른 1측은 직접 실내열교환기와 연결되도록 하여, 난방시 주위온도가 과부하 조건으로 되면 실내열교환기에 부착된 온도감지센서가 이를 감지하여 냉매를 3방변의 회로중 실외측열교환기의 하단부를 경유하는 냉매관으로 순환시키도록 함으로써 실외열교환기의 응축수와 실외팬에 의해 온도와 압력을 낮아지도록 하여 압축기에 가해지는 과부하를 개선할 수 있다.An object of the present invention can be solved by lowering the temperature and pressure of the indoor heat exchanger and the outdoor heat exchanger when the temperature and pressure rises when the ambient temperature is an overload condition during heating, for this purpose, a temperature sensor is attached to the indoor heat exchanger and the compressor Connect the three sides operated by the temperature sensor to the discharge part, one side is connected to the indoor heat exchanger through the bottom of the outdoor heat exchanger, and the other side is directly connected to the indoor heat exchanger. The temperature sensor attached to the indoor heat exchanger detects this and circulates the refrigerant to the refrigerant pipe via the lower end of the outdoor side heat exchanger in the three-way circuit, thereby reducing the temperature and pressure by the condensate and the outdoor fan of the outdoor heat exchanger. The overload on the compressor can be improved.

본 발명은 실외측 열교환기의 응축수를 이용한 난방 과부하 방지구조에 관한 것으로 특히 실외측 열교환기 하단부에 압축기 토출 파이프가 지나가도록 회로를 구성함으로써, 난방시 주위온도가 과부하조건으로 될 때 실외열교환기에서 생성되는 응축수와 실외팬에 의해 냉매의 온도 및 압력을 낮추어지도록 하여 압축기에 가해지는 과부하를 방지할 수 있도록 한 실외열교환기의 응축수를 이용한 난방 과부하 방지구조에 관한 것이다.The present invention relates to a heating overload prevention structure using condensate from an outdoor heat exchanger, and in particular, by configuring a circuit so that a compressor discharge pipe passes through a lower end of an outdoor heat exchanger, when the ambient temperature becomes an overload condition during heating, The present invention relates to a heating overload prevention structure using condensate of an outdoor heat exchanger to reduce the temperature and pressure of the refrigerant by the condensate and the outdoor fan to prevent the overload applied to the compressor.
종래의 일반적인 냉난방 겸용 공기조화기의 냉동 사이클의 구조는 제1도에 도시하였다.The structure of a refrigeration cycle of a conventional general air-conditioning combined air conditioner is shown in FIG.
종래기술의 일반적인 실내 냉난방 공기 조화기는 제1도에서와 같이 실내열교환기(1)와 실외교환기 사이(2)에 한쪽으로는 모세관(6)이 있고 다른 한쪽으로는 액분리기(9)와 압축기(5) 그리고 고압압력스위치(8)을 구비하고 있으며 실외열교환기(2)의 외부에는 실외팬(7)을 구비한 구성의 냉매 순환 구조를 이루고 있으며, 이 사이클 내에 냉매가 압축,응축,팽창,증발의 과정을 재반복하면서 원하는 실내의 난방효과를 얻을 수 있게 된다.A conventional indoor air conditioning air conditioner of the prior art has a capillary tube (6) on one side and a liquid separator (9) and a compressor (on the other side) between the indoor heat exchanger (1) and the outdoor exchanger (2) as shown in FIG. 5) And the high pressure switch (8) and the outside of the outdoor heat exchanger (2) constitutes a refrigerant circulation structure having an outdoor fan (7), the refrigerant is compressed, condensed, expanded, By repeating the process of evaporation, the desired heating effect of the room can be achieved.
그런데 난방시 주위온도가 과부하 조건으로 되면 실내열교환기(1) 및 실외열교환기(2)내의 온도와 압력이 상승하고 그 결과 압축기(5)에 고온 고압의 냉매가 유입됨으로서 압축기(5)에 과부하가 걸리게 되는데 이때 압축기(5)에 일정 이상의 압력을 넘어서면 압축기(5) 배출구에 있는 고압압력스위치(8)가 작동하여 압축기(5) 운전을 정지시키고 아울러 실외팬(7)의 모타에 인입되는 전기를 차단하여 팬(7)을 정지시키도록 하였다.However, when the ambient temperature becomes an overload condition during heating, the temperature and pressure in the indoor heat exchanger 1 and the outdoor heat exchanger 2 increase, and as a result, a high temperature and high pressure refrigerant flows into the compressor 5, thereby overloading the compressor 5. At this time, if the compressor 5 exceeds a certain pressure, the high pressure switch 8 at the outlet of the compressor 5 is operated to stop the operation of the compressor 5 and to be introduced into the motor of the outdoor fan 7. The electricity was shut off to stop the fan 7.
그런데 상기 종래기술의 공조기 구조는 난방시 주위온도가 과부하 조건일 때 압축기의 운전이 정지되기 때문에 연속적인 난방이 이루어질 수 없어 난방효율이 저하될 뿐만 아니라, 갑작스런 찬바람 취출로 인하여 사용자는 커다란 불편을 느껴야 했다. 요컨대 상기 종래기술의 공기조화기 구조는 압축기(5)에 가해지는 과부하에 대하여 단지 압축기(5) 작동을 중단시키는 것으로 해결하는 미봉책에 그치는 것이었으며 압축기(5)의 운전정지때문에 발생하는 난방효율의 감소라던지 혹은 사용자의 불편에 대해서는 이를 해결할 만한 아무런 수단을 구비하고 있지 못한 것이라고 할 수 있다.By the way, the air conditioner structure of the prior art, because the operation of the compressor is stopped when the ambient temperature is an overload condition when heating, not only the continuous heating can not be achieved, but also the heating efficiency is lowered, the user must feel a great inconvenience due to the sudden cold wind blowing did. In other words, the air conditioner structure of the related art is merely an unsolved solution to stop the operation of the compressor 5 in response to the overload applied to the compressor 5, and the heating efficiency caused by the operation of the compressor 5 is stopped. Reduction or inconvenience to the user can be said to have no means to solve this.
본 발명은 위와같은 종래의 기술이 가지고 있는 문제점을 해결하기 위한 것으로서 그 구체적인 실시예를 첨부된 도면에 의거 구체적으로 설명하면 다음과 같다.The present invention is to solve the problems of the prior art as described above in detail with reference to the accompanying drawings the specific embodiment as follows.
본 발명에서는 제2도에 도시된 바와 같이 실내열교환기(1)에 온도감지센서(11)를 부착하고 압축기(5) 토출부에는 3방변(10)을 설치하되, 3방변의 ②방향은 실외열교환기(2) 하단부를 지나 실내열교환기(1)로 연결되도록 하고, 나머지 ①방향은 곧 바로 실내열교환기(1)로 연결되도록 한 것으로서 3방변(10)이 상기 실내열교환기(1)에 부착된 온도감지센서(11)에 의하여 동작되도록 한 것이다.In the present invention, as shown in FIG. 2, the temperature sensor 11 is attached to the indoor heat exchanger 1, and the three discharge sides 10 are installed at the discharge part of the compressor 5, and the ② direction of the three directions is outdoors. It passes through the lower end of the heat exchanger (2) and connected to the indoor heat exchanger (1), and the remaining ① direction is directly connected to the indoor heat exchanger (1), and the three sides 10 are connected to the indoor heat exchanger (1). It is to be operated by the attached temperature sensor (11).
위와같은 구성의 본 발명에 있어서는 먼저 실내열교환기(1)에 부착된 온도감지센서(11)는 실내열교환기(1) 내의 온도를 감지하여 온도와 압력이 일정이하의 정상상태일 경우에는 냉매를 3방변(10)의 ①방향으로 통하게 하고, 고온 고압의 난방과부하시에는 냉매를 ②방향으로 흐르게 한다. 고온 고압의 난방 과부하 조건일 때 온도감지센서(11)의 동작에 의해 냉매가 ②방향으토 순환되면 실외팬(7)과 실외열교환기(2)에서 생성되는 응축수에 의하여 냉매의 온도와 압력이 낮추어 지므로 냉매 순환시 압축기(5)에 과도하게 가해지는 부하를 방지할 수 있다. 따라서 본 발명을 이용할 시에는 압축기의 연속적인 동작으로 가능해 짐으로서 지속적인 난방 효과를 얻을 수 있게 된다.In the present invention having the above-described configuration, first, the temperature sensor 11 attached to the indoor heat exchanger 1 senses the temperature in the indoor heat exchanger 1 to provide a refrigerant when the temperature and pressure are in a steady state below a certain level. In the direction of ① of the three sides 10, the refrigerant flows in the direction of ② under high temperature and high pressure heating. When the refrigerant is circulated in the direction of ② by the operation of the temperature sensor 11 in the heating overload condition of high temperature and high pressure, the temperature and pressure of the refrigerant are lowered by the condensed water generated in the outdoor fan 7 and the outdoor heat exchanger 2. Therefore, an excessive load on the compressor 5 during the refrigerant circulation can be prevented. Therefore, when using the present invention it is possible to achieve a continuous heating effect by being possible by the continuous operation of the compressor.
