본 고안은 실내나 밀폐된 공간에서 냉방기의 평균 온도 감지회로를 이용하여 평균 온도를 자동으로 제어하기 위한 냉방기 평균온도 감지회로에 관한 것이다.The present invention relates to an air conditioner average temperature detection circuit for automatically controlling the average temperature using the air conditioner's average temperature detection circuit in a room or enclosed space.

종래에는 실내온도 센서를 1개만 사용하기 때문에 실내 온도센서 주위의 급격한 온도 변화에 대하여 압축기가 단속이 걸려 설정된 온도보다 높아지며 이 때문에 실내 온도가 균일하지 않는 결합이 있었다.Conventionally, since only one indoor temperature sensor is used, the compressor is intermittent due to a sudden temperature change around the indoor temperature sensor, which is higher than the set temperature.

본 고안은 상기와 같은 결함을 해결하기 위하여 안출한 것인바, 실내 온도센서를 4개 사용하여 실내 주위에 평균온도를 감지하기 때문에 급격한 주위온도 변화에 대하여 압축기에 무리를 주지않고 일정한 동작을 하여 쾌적한 냉방을 실현하기 위한 것으로서 이하 첨부된 도면에 의하여 본 고안의 구성을 설명하면 다음과 같다.The present invention was devised to solve the above-mentioned defects. Since the average temperature is sensed around the room by using four indoor temperature sensors, the compressor is constantly operated without constant pressure on the compressor against sudden changes in ambient temperature. Hereinafter, the configuration of the present invention will be described with reference to the accompanying drawings as to realize cooling.

실내 온도를 감지하는 실온 센서부(10)는 각각의 실온 센서(TH1∼TH4)에 저항(R1∼R4)과 비교기(OP1)의 입력 비반전 단자(+)를 연결하고 상기 비교기(OP1∼OP4)의 출력신호를 궤환시켜서 비교기(OP1)의 입력반전단자(-)에 입력시킬 수 있도록 상기 비교기(OP1∼OP4)출력단자를 그의 입력반전 단자(-)에 각각 연결하고, 상기 비교기(OP1, OP2, OP3, OP4)의 출력단자는 평균 온도 회로부(20)내의 저항(R5), (R6), (R7), (R8)을 통하여 비교기(OP5)의 입력반전 단자(-)에 접속시킴과 동시에 저항(R9)을 상기 비교기(OP5)의 입력반전 단자(-)와 출력단자에 병렬로 연결하고, 상기 비교기(OP5)의 입력 비반전 단자(+)에 저항 (R10), (R11)이 접속된 그의 비교기(OP5)의 출력단자는 온도 비교부(30) 내의 저항(R12)을 통해 비교기(OP6)의 입력 비반전 단자(+)에 연결하고 상기 비교기(OP6)의 입력반전 단자(-)와 출력 단장에 저항(R13)을 병렬로 접속하고 상기 비교기(OP5)의 입력반전 단자(-)에는 온도조절기(VR)와 저항(R14), (R15)을 연결하며, 상기 비교기(OP6)의 출력단자는 구동부(40)내의 저항(R16)을 통하여 트랜지스터(TR1)의 베이스단에 접속하고 상기 트랜지스터(TR1)의 에미터 단이 접지된 그의 콜렉터 단은 다이오드(D1)와 압축기(C)의 동작을 제어하는 릴레이(RLY1)에 연결하여서 구성된 것이다.Room temperature sensor unit 10 for detecting the room temperature is connected to a resistor (R 1 ~R 4) and the non-inverting comparator input terminal (+) of (OP 1) to each of the room temperature sensor (TH 1 ~TH 4) and the the comparator (OP 1 ~OP 4) an output terminal inverted its input terminal so as to input to the (-) - a comparator (OP 1 ~OP 4) fed back by the output signal of the comparator input of the inverting terminal (OP 1) () The output terminals of the comparators OP 1 , OP 2 , OP 3 , and OP 4 are respectively connected to the resistors R 5 , R 6 , R 7 , and R 8 in the average temperature circuit section 20. a and simultaneously connected to the resistor (R 9) input-inverting terminal of the comparator (OP 5) - () ( -) connected in parallel to the output terminal, and the comparator (a comparator (OP 5) input inverting terminal of via OP 5) a comparator via a resistor (R 12) in the input non-inverting terminal (+) to the resistor (R 10), (R 11 ) an output terminal of its comparator (OP 5) connected to the temperature comparing section 30 of the ( connected to the non-inverting input terminal (+) of the OP 6) and The comparator (OP 6) input-inverting terminal of the (-) and a parallel connection of a resistance (R 13) to the output refurbished and type-inverting terminal of the comparator (OP 5) (-) and the temperature regulator (VR) resistance (R 14 ) and (R 15 ), and the output terminal of the comparator OP 6 is connected to the base terminal of the transistor TR 1 through the resistor R 16 in the driving unit 40 and is connected to the base of the transistor TR 1 . The collector stage whose emitter stage is grounded is configured by connecting to a relay RLY 1 which controls the operation of the diode D 1 and the compressor C.

상기와 같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.

실래 온도가 높으면 센서부(10) 4개의 실온센서(TH1∼TH4)에 의하여 감지된 온도가 높기 때문에 전압은 낮아지고 따라서 낮은 전압이 각각 4개의 비교기(OP1∼OP4)입력비반전 단자(+)에 인가되어 출력되고 상기 출력은 평균온도 회로부(20)내의 저항(R5∼R8)을 통하여 비교기(OP5)의 입력반전 단자(-)에 인가되어 저항(R5∼R8)과 저항(R9)의 값에 의해 온도에 해당하는 전압이 비교기(OP5)에서 평균네어져 출력된다.If the actual temperature is high, since the temperature detected by the four room temperature sensors (TH 1 to TH 4 ) of the sensor unit 10 is high, the voltage is lowered, and thus the low voltages are respectively input to four comparators (OP 1 to OP 4 ). and the output is applied to the terminal (+), the output resistance (R 5 ~R 8) input of the comparator (OP 5) through the inverting input terminal in the mean temperature circuit 20 (-) is applied to the resistor (R 5 ~R 8 ) The voltage corresponding to the temperature is averaged by the comparator OP 5 and outputted according to the values of the resistor R 9 .

좀더 상세하게는 비교기(OP1)의 출력을 E1비교기(OP2)을 출력을 E2, 비교기(OP3)의 출력을 E3, 비교기(OP4)의 출력을 E4로 하면, 각각의 비교기(OP1∼OP4)의 출력단자에 연결된 저항(R5∼R8)은 동일한 저항이므로 즉 R5=R6=R7=R8이 된다.More specifically, when the output of the comparator the output of the output of the (OP 1) E 1 comparator to output a (OP 2) E 2, the comparator (OP 3) E 3, a comparator (OP 4) to E 4, respectively, Since the resistors R 5 to R 8 connected to the output terminals of the comparators OP 1 to OP 4 have the same resistance, that is, R 5 = R 6 = R 7 = R 8 .

이것을 R로 표시하고 R9를 R/4로 설정하면, 이때 비교기(OP5)의 출력전압 V0If this is expressed as R and R 9 is set to R / 4, the output voltage V 0 of the comparator OP 5 is

로 되므로 상기 비교기(OP5)의 출력단으로 평균된 값의 전압 즉 온도가 산출된다. Therefore, the voltage, that is, the temperature of the average value is calculated at the output terminal of the comparator OP 5 .

상기와 같이 비교기(OP5)로부터 출력된 평균값의 전압은 실내온도가 높으면 높아지기 때문에 저항(R12)을 통하여 비교기(OP6)의 입력비반전 단자(+)에 인가되고 인가된 평균 출력 신호는 온도 조절기(VR)에 의하여 설정된 온도 전압보다 높으므로 비교기(OP6)의 출력단으로부터 신호가 출력되고, 출력된 하이신호는 구동부(40)내의 저항(R16)을 통하여 트랜지스터(TR1)베이스단에 인가되어 트랜지스터(TR1)가 도통된다.As described above, since the voltage of the average value output from the comparator OP 5 increases when the room temperature is high, the average output signal applied to the input non-inverting terminal + of the comparator OP 6 through the resistor R 12 is applied. Since the temperature is higher than the temperature voltage set by the temperature controller VR, a signal is output from the output terminal of the comparator OP 6 , and the output high signal is outputted from the base of the transistor TR 1 through the resistor R 16 in the driver 40. Is applied to the transistor TR 1 .

이때 전압 (VCC)은 릴레이(RLY1)와 트랜지스터(TR1)의 콜렉터 및 에미터단을 통하여 접지(GND)되므로 릴레이(RLY1)가 동작되고 따라서 압축기(C)가 작동하기 시작한다.At this time, since the voltage VCC is grounded through the collector and emitter stages of the relay RLY 1 and the transistor TR 1 , the relay RLY 1 is operated and thus the compressor C starts to operate.

한편, 실내온도가 온도비교부(30)내의 온도조절기(VR)에 의하여 설정된 온도 보다 낮아지면 평균온도 회로부(20)내의 비교기(OP5)의 출력 전압은 감소되고 따라서 비교기(OP6)의 출력단자로 로우(LOW)신호가 출력되어 트랜지스터(TR1)의 베이스단에 인가되므로 트랜지스터(TR1)는 동작하지 않는다.On the other hand, when the room temperature is lower than the temperature set by the temperature controller VR in the temperature comparator 30 , the output voltage of the comparator OP 5 in the average temperature circuit part 20 decreases and thus the output of the comparator OP 6 . is a low (lOW) signal output to the terminal so applied to the base of the transistor (TR 1) transistor (TR 1) is not operated.

이때 전압(VCC)은 릴레이(RLY1)와 트랜지스터(TR1)는 동작을 멈추게 되고 따라서 압축기(C)도 동작을 멈추어 실내온도는 높아지게 된다.At this time, the voltage VCC stops the operation of the relay RLY 1 and the transistor TR 1 , and thus the compressor C also stops the operation, thereby increasing the room temperature.

상기와 같이 실내온도를 평균 온도로 제어할때 실온 센서를 4개 사용함으로써 실내의 곳곳에 설치하여 전체 실내를 평균온도로 제어하기 때문에 쾌적한 냉방을 할 수 있고 급격한 실내온도 변화에 대해서도 안전한 냉방 동작을 할수 있는 편리한 점이 있다.When controlling the room temperature to the average temperature as described above, by using four room temperature sensors, it is installed in various places in the room to control the whole room to the average temperature, so that the user can enjoy a comfortable cooling and safe cooling operation even in the case of a sudden change in the room temperature. There is a convenient thing to do.
