압축기 온도센서 이탈감지방법 { Method for detecting a separation of a temperature sensor of a compressor}{Method for detecting a separation of a temperature sensor of a compressor}

본　발명은　공기조화기에　관한　것으로서，보다　상세하게는 압축기 온도센서가　본래의　위치에서　이탈할　경우,　이를　감지하는 압축기 온도센서 이탈감지방법에　관한　것이다．The present invention relates to an air conditioner and, more specifically, to a method of detecting the departure of the compressor temperature sensor, which detects when the compressor temperature sensor is moved out of its original position.

일반적으로　공기조화기는　압축기，실외열교환기，모세관，실내열교환기로 구성된　냉동싸이클에서　냉매의　열교환작용에　의하여　냉방운전을　수행한다．이때，공기조화기는　상술한　냉방운전을　수행하기　위해서　여러가지의 냉방운전 실행조건을　설정한다．그리고，공기조화기는 주위　환경과　사용자의　조작에 의해　상기　설정조건에　해당되면　냉방운전을　실행한다．그러므로，공기조화기는 상기　설정조건과　현재상태를 비교하기　위한　감지수단이　구비되는 바，일반적인　감지수단으로　센서가　사용된다．이와　같은　공기조화기의 구성을　도　１에 도시하였다．In general, an air conditioner performs a cooling operation in accordance with the heat exchange action of a refrigerant in a refrigeration cycle consisting of a compressor, an outdoor heat exchanger, a capillary, and an indoor heat exchanger. The air conditioner performs the cooling operation when the above conditions are met by the surrounding environment and the user's operation. Therefore, the air conditioner is equipped with a sensing means for comparing the current condition with the above setting conditions. F. The sensor is used as a general sensing means. The configuration of the air conditioner is shown in FIG.

도　１은　일반적인　공기조화기의　구성을　나타낸　제어블럭도이다．　Fig. 1 is a control block diagram showing the configuration of a typical air conditioner.

전원부(10)와　센서부(70)　및　키입력부(60)는　마이컴(40)에　전원　및　감지신호를　전달하고，표시부(50)와　부하구동부(20)는　마이컴(40)에 의해 제어된다．The power supply unit 10, the sensor unit 70, and the key input unit 60 transmit power supply and detection signals to the microcomputer 40, and the display unit 50 and the load driving unit 20 are controlled by the microcomputer 40.

전원부(10)는　전원을　공급하는　구성요소이고，키입력부(60)는　사용자의 선택신호를　전달한다．센서부(70)는 실내의 온도를 감지하는 실내온도센서(71)와, 실외의 온도를 감지하는 실외온도센서(72)와, 실외열교환기의 온도를 감지하는 실외열교환기 온도센서(74)를 포함한다. 또한, 실내열교환기의 온도를 감지하는 실내열교환기 온도센서(73)와, 압축기의 온도를 감지하는 압축기 온도센서(75)를 더 포함한다. 　The power supply unit 10 is a component for supplying power, and the key input unit 60 transmits a user's selection signal. The sensor unit 70 includes an indoor temperature sensor 71 for sensing an indoor temperature and an outdoor temperature. It includes an outdoor temperature sensor 72 for sensing the temperature, and an outdoor heat exchanger temperature sensor 74 for detecting the temperature of the outdoor heat exchanger. In addition, the indoor heat exchanger temperature sensor 73 for detecting the temperature of the indoor heat exchanger, and the compressor temperature sensor 75 for detecting the temperature of the compressor further includes.

이하, 상기와 같은 구성을 갖는 공기조화기에서 종래의 압축기 온도센서의 이상을 감지하는 방법을 설명한다.Hereinafter, a method of detecting an abnormality of a conventional compressor temperature sensor in an air conditioner having the above configuration will be described.

도 2는 종래의 압축기 온도센서의 이상감지방법을 나타낸 플로우 차트이다.2 is a flowchart illustrating a method of detecting an abnormality of a conventional compressor temperature sensor.

사용자가　키입력부(60)에　구성된　구동스위치(도시되지 않음)를　온하게　되면　마이컴(40)에　구동선택신호가　전달된다(S1)．마이컴(40)은　상기　구동선택신호가　인가됨에　따라서　실내온도센서(71)와　실외온도센서(72)를　통하여 실내 및 실외의　온도를　감지한다．그리고，마이컴(40)은 감지된　실외온도에　따라서　내부에 저장된 설정온도와, 실내온도센서(71)를 통하여 감지된　실내온도를　비교판단한다(S2)．비교판단결과，실내온도가　설정온도보다　높으면，마이컴(40)은　부하구동부(20)를　제어하여　공기조화기의　냉방운전을　실시한다(S3)．따라서，공기조화기는　토출구(도시되지 않음)를　통해서　차가운공기를 토출함으로　실내의　온도를　적정온도로　낮추기 시작한다．When the user turns on the drive switch (not shown) configured in the key input unit 60, the drive selection signal is transmitted to the microcomputer 40 (S1). The microcomputer 40 is subjected to the above-described drive selection signal, and thus the room temperature. Through the sensor 71 and the outdoor temperature sensor 72, the indoor and outdoor temperatures are sensed. The microcomputer 40 stores the set temperature stored in the interior according to the detected outdoor temperature and the indoor temperature sensor 71. The detected indoor temperature is compared (S2). As a result of the comparison judgment, when the indoor temperature is higher than the set temperature, the microcomputer 40 controls the load driving unit 20 to perform cooling operation of the air conditioner (S3). Therefore, the air conditioner starts to lower the indoor temperature to the appropriate temperature by discharging cold air through the discharge outlet (not shown).

상기　냉방운전 실시단계(S3) 이후，마이컴(40)은　압축기 온도센서(75)의 이상유무를 판단한다. 즉, 압축기 온도센서(75)에서 전달되는 압축기 온도감지신호의 유무에 따라서 이상유무를 판단한다(S4).After the cooling operation execution step (S3), the microcomputer 40 determines whether there is an abnormality of the cooling compressor temperature sensor 75. That is, it is determined whether there is an abnormality according to the presence or absence of the compressor temperature detection signal transmitted from the compressor temperature sensor 75 (S4).

따라서, 상기 압축기 온도센서(75)의 이상유무 판단단계(S4)에서, 상기 마이컴(40)은 압축기 온도센서(75)로 부터 신호가 전달되지 않으면 표시부(50)를 제어하여 압축기 온도센서(75)의 에러모드표시를 나타나게 한다(S5). 또한, 마이컴(40)은 부하구동부(20)를 제어하여 압축기(도시되지 않음)를 오프시킴으로 냉방운전을 종료한다. 이때, 사용자는 상기 압축기 온도센서(75)의 연결상태, 즉, 상기 압축기 온도센서(75)와 회로기판(도시되지 않음)을 연결시키는 와이어(Wire)와 커넥터(Connector)의 상태를 조사함으로 고장을 원인을 찾을 수 있다.Accordingly, in the step S4 of determining whether the compressor temperature sensor 75 is abnormal, the microcomputer 40 controls the display unit 50 when a signal is not transmitted from the compressor temperature sensor 75 so as to control the compressor temperature sensor 75. Error mode display (S5). In addition, the microcomputer 40 ends the cooling operation by controlling the load driving unit 20 to turn off the compressor (not shown). At this time, the user breaks down by checking the connection state of the compressor temperature sensor 75, that is, the state of a wire and a connector connecting the compressor temperature sensor 75 and a circuit board (not shown). Find the cause.

또한, 상기 압축기 온도센서(75)의 이상유무 판단단계(S4)에서, 상기 압축기 온도센서(75)로 부터 신호가 전달되면 부하구동부(20)를 제어하여 정상적인 냉방운전을 수행한다(S6).In addition, in step S4 of determining whether the compressor temperature sensor 75 is abnormal, when a signal is transmitted from the compressor temperature sensor 75, the load driving unit 20 is controlled to perform normal cooling operation (S6).

상기 냉방운전수행단계(S6) 이후, 마이컴(40)은 정지선택신호가 인가되는 지를 판단한다(S7). 이때, 사용자가 키입력부(60)에 구성된 정지스위치(도시되지 않음)를 온하면 마이컴(40)은 상기 정지선택신호를 인지한다. 따라서, 마이컴(40)은 정지선택신호가 인가됨에 따라 부하구동부(20)를 제어하여 각 부하를 오프시킴으로 냉방운전을 종료한다.After the cooling operation performing step (S6), the microcomputer 40 determines whether the stop selection signal is applied (S7). At this time, when the user turns on the stop switch (not shown) configured in the key input unit 60, the microcomputer 40 recognizes the stop selection signal. Therefore, the microcomputer 40 terminates the cooling operation by turning off each load by controlling the load driving unit 20 as the stop selection signal is applied.

그러나，이와　같은　종래의 압축기 온도센서 이상감지방법은 상기 압축기 온도센서를 회로기판에 연결시키는 와이어와　커넥터의 연결상태가 불량하여 센서를 인지할 수 없는 경우에만 해당된다. 따라서, 상기 압축기 온도센서가　원래의 위치에서　이탈할　경우，마이컴은 이탈센서에서 전달되는 온도감지신호로써　부적절한 제어를 하게 되므로, 공기조화기의　시스템에　치명적인　손상이　발생되는 문제점이　있다．　However, such a conventional compressor temperature sensor abnormality detection method is applicable only if the sensor cannot be recognized because the connection between the wire and the fan connector connecting the compressor temperature sensor to the circuit board is poor. Therefore, when the compressor temperature sensor is displaced from its original position, the microcomputer improperly controls the temperature detection signal transmitted from the dissipation sensor, which causes a serious damage to the air conditioner system.

따라서，본　발명은　상기와　같은　문제점을　해결하기　위하여　안출한　것으로서，실내외 온도와 실내외 열교환기 및 압축기 온도센서에서 감지된 온도에 대한 일정조건을 정함으로 압축기 온도센서가 본래의　위치에서　이탈됨을　감지할 수 있는 압축기 온도센서 이탈감지방법을　제공함을　목적으로　한다．Therefore, the present invention was devised to solve the above-mentioned problems, and it is possible to detect the deviation of the compressor temperature sensor from the original position by setting a certain condition for the indoor and outdoor temperature and the temperature detected by the indoor and outdoor heat exchanger and compressor temperature sensor. It aims to provide a method for detecting the deviation of the compressor temperature sensor.

그러므로, 상기와 같은 본 발명에 따른 압축기 온도센서 이탈감지방법은 압축기 온도센서가 고정위치로 부터 이탈됨을 감지하여 압축기 온도센서 이탈표시와 함께 공기조화기의 동작을 중지시키므로 압축기 온도센서가 이탈됨으로써 마이컴의 부적절한 제어로 인한 공기조화기의 시스템 손상을 미연에 방지하는 효과가 있다.Therefore, the compressor temperature sensor departure detection method according to the present invention as described above detects that the compressor temperature sensor is separated from the fixed position and stops the operation of the air conditioner with the compressor temperature sensor departure indication so that the microcomputer by leaving the compressor temperature sensor It is effective to prevent system damage of the air conditioner due to improper control of the air conditioner.

이하, 본 발명에 따른 압축기 온도센서 이탈감지방법의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, a preferred embodiment of the compressor temperature sensor departure detection method according to the present invention will be described in detail.

도 3은 본 발명에 따른 압축기 온도센서의 이탈감지방법을 나타낸 플로우 차트이며, 아울러 종래와 동일한 구성요소는 동일부호를 부여하여 설명한다.3 is a flow chart showing a departure detection method of the compressor temperature sensor according to the present invention, and the same components as in the prior art will be described with the same reference numerals.

최초단계에서, 마이컴(40)은 구동선택신호가 인가되는 지를 판단한다(S21). 따라서, 사용자가 키입력부(60)에 구성된 구동스위치(도시되지 않음)를 온하면 마이컴(40)은 상기 키입력부(60)로 부터 전달되는 구동선택신호를 인지한다.In the first step, the microcomputer 40 determines whether the drive selection signal is applied (S21). Therefore, when the user turns on the drive switch (not shown) configured in the key input unit 60, the microcomputer 40 recognizes the drive selection signal transmitted from the key input unit 60.

상기 구동선택신호 감지단계(S21) 이후, 마이컴(40)은 실내온도센서(71)를 통하여 감지되는 실내의 온도를 인지하고, 실외온도센서(72)에서 전달되는 실외온도를 인지한다. 그리고, 마이컴(40)은 상기 실외온도에 대비되어 설정된 상기 공기조화기의 냉방운전 실시가능온도와 실내온도를 비교판단한다(S22). 판단결과, 실내온도가 설정온도에 비해 높으면 각부하를 제어하여 냉방운전을 실행한다(S23).After the driving selection signal detection step S21, the microcomputer 40 recognizes the indoor temperature detected by the indoor temperature sensor 71, and recognizes the outdoor temperature transmitted by the outdoor temperature sensor 72. Then, the microcomputer 40 compares the room temperature with the room temperature for performing the cooling operation of the air conditioner set in contrast to the outdoor temperature (S22). As a result, when the indoor temperature is higher than the set temperature, the cooling operation is performed by controlling each load (S23).

상기 냉방운전 실행단계(S23) 이후, 마이컴(40)은 카운터(30)를 통하여 냉방운전 실행시간이 4분이 경과하였음을 감지한다(S24). 따라서, 마이컴(40)은 냉동싸이클의 각구성요소가 정상운전시에 도달되는 온도범위에 도달하였다고 판단하여, 실내온도센서(71)와 실내열교환기 온도센서(73)를 통하여 실내온도와 실내열교환기 온도를 감지한다(S25). 그리고, 상기 감지단계(S25)에서 인지된 실내온도에서 실내열교환기 온도를 뺀 결과값이 일정치 보다 큰지를 비교판단한다(S26).After the cooling operation execution step (S23), the microcomputer 40 detects that the cooling operation execution time has elapsed 4 minutes through the counter 30 (S24). Therefore, the microcomputer 40 determines that each component of the refrigeration cycle has reached the temperature range reached in normal operation, and thus, the indoor temperature and the indoor heat exchanger through the indoor temperature sensor 71 and the indoor heat exchanger temperature sensor 73. Sensing the temperature (S25). Then, it is determined whether the resultant value obtained by subtracting the indoor heat exchanger temperature from the perceived indoor temperature in the sensing step S25 is greater than a predetermined value (S26).

상기 비교판단단계(S26)에서, 결과값이 일정치보다 작으면, 마이컴(40)은 실내열교환기의 열교환작용이 원활하게 이루어지지 않음을 판단하여 표시부(50)를 제어하여 냉동싸이클의 확인요구표시를 나타낸다(S35). 그리고, 마이컴(40)은 부하구동부(20)를 제어하여 압축기(도시되지 않음)를 오프시킨다. 아울러, 사용자는 냉동싸이클을 순환하는 냉매의 누설여부를 판단함이 바람직하다. 또한, 사용자는 마이컴(40)이 압축기 온도센서(75)가 이탈되어 잘못된 온도를 마이컴(40)에 전달하여, 마이컴(40)의 부적절한 제어로 인하여 냉매싸이클의 열교환작용이 위축되었는 지를 확인함이 바람직하다. 상기 비교판단단계(S26)에서 일정치는 5℃로 정함이 바람직하다.In the comparison determination step (S26), if the result value is smaller than a predetermined value, the microcomputer 40 determines that the heat exchange action of the indoor heat exchanger is not performed smoothly, and controls the display unit 50 to confirm the refrigeration cycle. Indication (S35). Then, the microcomputer 40 controls the load driving unit 20 to turn off the compressor (not shown). In addition, the user preferably determines whether the refrigerant circulates through the refrigeration cycle. In addition, the user checks whether the microcomputer 40 decompresses the compressor temperature sensor 75 and transmits the wrong temperature to the microcomputer 40, thereby reducing the heat exchange action of the refrigerant cycle due to improper control of the microcomputer 40. desirable. In the comparative determination step (S26) it is preferable to set a predetermined value to 5 ℃.

상기 비교판단단계(S26)에서, 상기 결과치가 일정치보다 크면, 마이컴(40)은 실외온도센서(72)와 실외열교환기 온도센서(74)를 통하여 실외온도와 실외열교환기의 온도를 감지한다(S27). 그리고, 상기 실외온도와 실외열교환기 온도감지단계이후, 감지된 실외열교환기 온도에서 실외온도를 뺀 결과값이 일정치 보다 큰지를 비교판단한다(S28). 아울러, 상기 일정치는 5℃로 정함이 바람직하다.In the comparison determination step (S26), if the result value is larger than a predetermined value, the microcomputer 40 detects the outdoor temperature and the temperature of the outdoor heat exchanger through the outdoor temperature sensor 72 and the outdoor heat exchanger temperature sensor 74. (S27). After the outdoor temperature and outdoor heat exchanger temperature sensing step, it is determined whether the resultant value obtained by subtracting the outdoor temperature from the detected outdoor heat exchanger temperature is greater than a predetermined value (S28). In addition, the constant value is preferably set to 5 ℃.

상기 비교판단단계(S28)에서, 결과치가 일정치보다 작으면, 마이컴(40)은 표시부(50)를 제어하여 압축기 온도센서의 이탈유무 및 냉동싸이클의 확인요구표시를 나타낸다(S35). 그리고, 마이컴(40)은 부하구동부(20)를 제어하여 압축기(도시되지 않음)를 오프시킨다(S34). 이때, 사용자는 상술한 바와 같이 냉동싸이클에서 냉매의 누설이 발생되었는지를 확인하고, 압축기 온도센서(75)의 위치를 확인함이 바람직한다.In the comparison determination step (S28), if the result value is less than a predetermined value, the microcomputer 40 controls the display unit 50 to display the presence or absence of the compressor temperature sensor and the confirmation request of the refrigeration cycle (S35). Then, the microcomputer 40 controls the load driving unit 20 to turn off the compressor (not shown) (S34). At this time, the user is to check whether the leakage of the refrigerant occurs in the refrigeration cycle as described above, it is preferable to check the position of the compressor temperature sensor (75).

또한, 상기 비교판단단계(S28)에서, 상기 결과치가 일정치 보다 크면, 마이컴(40)은 압축기 온도센서(75)를 통하여 압축기 온도를 감지하고(S29), 외기온도에 따라서 설정된 압축기 적정온도를 산출한다(S30). 그리고, 마이컴(40)은 감지된 압축기 온도에서 설정된 압축기 온도를 뺀 결과값이 소정치 보다 작은지를 비교판단한다(S31). 아울러, 상기 소정치는 20℃로 정함이 바람직하다.In addition, in the comparison determination step (S28), if the result value is larger than a predetermined value, the microcomputer 40 detects the compressor temperature through the compressor temperature sensor 75 (S29), and adjusts the compressor proper temperature set according to the outside air temperature. Calculate (S30). Then, the microcomputer 40 determines whether the result value obtained by subtracting the set compressor temperature from the detected compressor temperature is smaller than a predetermined value (S31). In addition, the predetermined value is preferably set to 20 ° C.

상기 비교판단단계(S31)에서, 상기 결과값이 소정치보다 작으면 마이컴(40)은 압축기 온도센서(75)가 설정된 위치에 고정됨을 인지하여 냉방운전을 계속 수행한다(S32).In the comparison determination step (S31), if the result value is less than a predetermined value, the microcomputer 40 recognizes that the compressor temperature sensor 75 is fixed to the set position continues to perform the cooling operation (S32).

그러나, 상기 비교판단단계(S31)에서, 결과값이 소정값보다 작지않으면, 마이컴(40)은 상기 압축기 온도센서(75)가 설정된 위치에서 이탈되었다고 판단하여 압축기를 오프시켜 냉방운전을 중지하고, 표시부(50)를 제어하여 압축기 온도센서가 이탈되었음를 표시한다(S33)(S34).However, in the comparison determination step (S31), if the result value is not smaller than a predetermined value, the microcomputer 40 determines that the compressor temperature sensor 75 is separated from the set position, the compressor is turned off to stop the cooling operation, The display unit 50 is controlled to indicate that the compressor temperature sensor is separated (S33) (S34).

상기와 같은 본 발명에 따른 압축기 온도센서 이탈감지방법은 압축기 온도센서가 고정위치로 부터 이탈됨을 감지하여 압축기 온도센서 이탈표시와 함께 공기조화기의 동작을 중지시키므로 압축기 온도센서가 이탈됨으로써 마이컴의 부적절한 제어로 인한 공기조화기의 시스템 손상을 미연에 방지하는 효과가 있다.Compressor temperature sensor deviation detection method according to the present invention detects that the compressor temperature sensor is separated from the fixed position and stops the operation of the air conditioner with the compressor temperature sensor departure indication, so that the compressor temperature sensor is separated by the inappropriate microcomputer It is effective to prevent system damage of the air conditioner due to the control.
