It relates to a control device to make.
종래의 냉매순환 경로는 제1도에 도시한 바와 같이 압축기(1)와 실외 얼교환기(2)를 통하여 모세관(3)과 실내 열교환기(4)로 순환된다.The conventional refrigerant circulation path is circulated to the capillary tube 3 and the indoor heat exchanger 4 through the compressor 1 and the outdoor ear exchanger 2 as shown in FIG.
상기 압축기(1)와 실외 열교환기(2)까지의 순환이 실외기 동작이고, 상기 모세관(3)과 실내 열교환기(4)의 순환이 실내기 동작이다The circulation between the compressor 1 and the outdoor heat exchanger 2 is the outdoor unit operation, and the circulation between the capillary tube 3 and the indoor heat exchanger 4 is the indoor unit operation.
종래 에어콘의 회로 구성은 제2도에 도시한 바와 같이 전원을 RST상에 인가후 주기판(5)의 송풍스위치(SW1)를 누르면 실내모터(7)가 운전하면서 송풍운전을 한다.In the circuit configuration of the conventional air conditioner, as shown in FIG. 2, when the power is applied to the RST and the blow switch SW1 of the main board 5 is pressed, the indoor motor 7 operates while blowing.
이때, 상기 송풍스위치(SW1)의 접속 위치에 따라 상기 실내모터(7)는 강, 약으로 운전한다.At this time, the indoor motor (7) is driven in a strong, weak depending on the connection position of the blowing switch (SW1).
한편, 상기 주기판(5)의 냉방스위치(SW2)를 온하면 전자접촉기 코일(9)에 전원이 인가되면서 전자접촉기(8)를 온시켜 압축기(1) 및 실외모터(10)에 전원이 인가되어 압축기(1)와 실외모터(10)가 동작된다.On the other hand, when the cooling switch SW2 of the main board 5 is turned on, the power is applied to the magnetic contactor coil 9 while turning on the magnetic contactor 8 so that power is applied to the compressor 1 and the outdoor motor 10. The compressor 1 and the outdoor motor 10 are operated.
이때, 실외축의 주위온도가 온도감지센서(TH)의 설정온도보다 낮을시 상기 실외모터(10)는 약으로 운전한다.At this time, when the ambient temperature of the outdoor shaft is lower than the set temperature of the temperature sensor (TH), the outdoor motor 10 operates about.
그러나, 만약 실외측의 온도가 상기 설정온도 보다 높으면 상기 실외모터(10)는 강으로 운전한다.However, if the outdoor side temperature is higher than the set temperature, the outdoor motor 10 operates in a strong manner.
이와 같이 상기 실외모터가 강으로 운전할때 실외측의 온도가 보조기판(6)내의 온도감지센서(TH)의 설정치보다 낮을시 상기 실외모터(10)는 약으로 운전하여 실외기 열교환기(2)의 효율이 저하되어 쾌적한 냉방운전을 하지 못하는 단점이 있다.As described above, when the outdoor motor is driven in a strong manner, when the outdoor side temperature is lower than the set value of the temperature sensor TH in the auxiliary substrate 6, the outdoor motor 10 is operated at a low level so that the outdoor motor heat exchanger 2 There is a disadvantage in that the efficiency is lowered and the cooling operation is not comfortable.
또한, 실내모터기(7)는 약으로 운전할 때 실외측의 온도가 상기 보조기판(6)내의 온도감지센서(TH)의 설정치보다 높으면 상기 실외모터(10)는 강으로 운전하여 상기 실외기 열교환기(2)의 효율이 증대되어 실내기 열교환기(4)에서 토출되므로 압축기(1)에 흡입되는 온도가 저하된다.In addition, when the indoor motor 7 is operated with a weak temperature when the outdoor side temperature is higher than the set value of the temperature sensor (TH) in the auxiliary substrate 6, the outdoor motor 10 is driven to the steel to the outdoor unit heat exchanger Since the efficiency of (2) is increased and discharged from the indoor unit heat exchanger (4), the temperature sucked into the compressor (1) is lowered.
따라서 계속적인 냉방운전에 의해 상기 압축기(1)의 결빙 및 실내기 열교환기(4)에 결빙이 생겨 압축기(1)의 소손 및 불충분한 냉방운전을 하는 문제점이 있었다.Accordingly, there is a problem that the freezing of the compressor 1 and the freezing of the indoor unit heat exchanger 4 are caused by the continuous cooling operation, resulting in burnout of the compressor 1 and insufficient cooling operation.
따라서 본 고안은 압축기로 유입되는 냉매의 압력을 감지하여 냉방운전의 강, 약을 조절하므로서 상기한 문제점을 해결하고자 한다.Therefore, the present invention is to solve the above problems by controlling the strength and weakness of the cooling operation by sensing the pressure of the refrigerant flowing into the compressor.

첨부한 제3도는 본 고안의 제어장치의 구성도로서, 압축기(1)의 입구 압력을 감지하는 압력감지센서(20)를 상기 압축기(1)의 입구에 설치하여, 상기 압축기(1)의 흡입압력을 감지하므로써 실외모터(1)의 풍량을 자동으로 조절하여 강, 약으로 운전한다.3 is a configuration diagram of the control device of the present invention, in which the pressure sensor 20 for detecting the inlet pressure of the compressor 1 is installed at the inlet of the compressor 1, and the suction of the compressor 1 is performed. By sensing the pressure, the air volume of the outdoor motor 1 is automatically adjusted to operate with strong and weak.
제4도는 본 고안의 회로구성도로서, 압축기(1)와 실외모터(10)는 전자접촉기(8)에 연결되며, 실외온도를 감지하여 실외모터(10)의 풍량을 절환시키는 보조기판(6)이 상기 실외모터(10)의 한쪽에 연결된다.4 is a circuit configuration diagram of the present invention, the compressor (1) and the outdoor motor 10 is connected to the magnetic contactor (8), and senses the outdoor temperature to switch the air volume of the outdoor motor (10) (6) ) Is connected to one side of the outdoor motor (10).
상기 보조기판(6)은 압축기(1)의 흡입압력을 감지하여 상기 실외모터(10)의 풀량을 절환시키는 압력감지센서(20)와 직렬로 연결되어 상기 실외모터(10)와 접속된다.The auxiliary substrate 6 is connected in series with a pressure sensor 20 that detects the suction pressure of the compressor 1 and switches the amount of the outdoor motor 10 to be connected to the outdoor motor 10.
전원은 RST상에 실내모터(10)와 전자접촉기(8)에 병렬로 접속된다.The power source is connected in parallel to the indoor motor 10 and the magnetic contactor 8 on the RST.
상기 보조기판(6)의 저속인 단자(62)와 상기 압력감지센서(20)의 고압단자(22)는 병렬로 연결되어 상기 실외모터(10)의 강에 연결된다.The low speed terminal 62 of the auxiliary substrate 6 and the high voltage terminal 22 of the pressure sensor 20 are connected in parallel to each other and to the steel of the outdoor motor 10.
또한, 상기보조기판(6)의 고속단자(63)는 상기 압력감지센서(20)의 고압단자(21)에 연결되고, 상기 압력감지센서(20)의 저압단자(23)는 상기 실외모터(10)의 약에 연결된다.In addition, the high speed terminal 63 of the auxiliary substrate 6 is connected to the high pressure terminal 21 of the pressure sensor 20, the low pressure terminal 23 of the pressure sensor 20 is the outdoor motor ( 10) is connected to the drug.
이와같이 구성된 본 고안의 동작 및 작용효과를 설명하면 다음과 같다.Referring to the operation and effect of the present invention configured as described above are as follows.
냉방운전 동작시, 실내모터(7)를 강(접점 53 접속)으로 운전할 때 실외측의 온도가 보조기판(6)내의 온도감지센서(TH)의 설정치보다 낮으면 상기 보조기판(6)내의 접점은 (61-63)에서 (61-62)로 이동하여 강으로 절환됨으로써 실외기는 강으로 운전하여 쾌적한 냉방운전을 한다.In the cooling operation, when the indoor motor 7 is operated in a strong state (contact 53 connection), if the temperature of the outdoor side is lower than the set value of the temperature sensor TH in the auxiliary substrate 6, the contact point in the auxiliary substrate 6 The silver moves from (61-63) to (61-62) and is switched to the river, whereby the outdoor unit is driven to the river for comfortable cooling operation.
한편, 상기 실내모터(7)를 약으로 운전할 때 실외측의 온도가 상기 보조기판(6)내의 온도감지센서(TH)의 설정치보다 높으면, 상기 보조기판(6)내의 접점은 (61-62)에서 (61-63)으로 전환접속되고, 상기 압력감지센서(20)의 접점은 (21-22)로 고정되어 초기의 실외모터(10)는 강으로 운전하지만, 실외기 열교환기(2)의 효율증가에 따라 압축기(1) 흡입축의 압력은 감소한다.On the other hand, when the indoor motor 7 is operated weakly, if the temperature of the outdoor side is higher than the set value of the temperature sensor TH in the auxiliary substrate 6, the contacts in the auxiliary substrate 6 are (61-62). Is connected to (61-63), the contact of the pressure sensor 20 is fixed to (21-22) so that the initial outdoor motor 10 is driven by steel, but the efficiency of the outdoor unit heat exchanger (2) As the pressure increases, the pressure in the suction shaft of the compressor 1 decreases.
따라서, 감소된 압력이 상기 압력감지센서(20)의 설정치보다 낮으면 상기 압력감지센서(20)의 접점은 (21-22)에서 (21-23)으로 전환접속되어 실외 모터(10)는 강에서 약으로 절환되고 상기 실외모터(10)는 약으로 운전한다.Therefore, if the reduced pressure is lower than the set value of the pressure sensor 20, the contact point of the pressure sensor 20 is switched from (21-22) to (21-23) so that the outdoor motor 10 is strong. Is switched to about and the outdoor motor 10 operates about.
이상에서와 같이 본 고안은 실내기, 실외기의 운전조건이 다를때 실외기의 온도 및 압력을 감지하여 실내기의 운전과 실외기의 운전을 동일하게 해주어 쾌적한 냉방운전을 하고, 압축기의 소손을 방지할 수 있는 유익한 효과가 있다.As described above, the present invention senses the temperature and pressure of the outdoor unit when the operating conditions of the indoor unit and the outdoor unit are different, thereby making the operation of the indoor unit the same as the operation of the outdoor unit to provide a pleasant cooling operation, and to prevent the damage of the compressor. It works.
