상기와 같이 구성된 본 발명의 작용을 살펴보면 다음과 같다.Looking at the operation of the present invention configured as described above are as follows.

입출력부(8)의 운전스위치를 누르면 운전명령이 제1제어부(2)에 전달되고,제1제어부(2)에서는 기억부(7)에 기억되어 있는 프로그램에 의해 운전에 들어갈 수 있는 모든 조건이 충족되어 있는가를 제1,제2 입력부(1)(5)를 통해 확인한다.When the operation switch of the input / output unit 8 is pressed, an operation command is transmitted to the first control unit 2, and in the first control unit 2, all conditions under which the operation can be entered by the program stored in the storage unit 7 are satisfied. Check whether it is satisfied by the 1st, 2nd input part (1) (5).

또한,확인 결과 운전조건이 충족되어 있으면,흡수액 펌프를 기동시키면서 운전을 수행하게 된다.In addition, if the operation condition is satisfied as a result of the check, the operation is performed while starting the absorbent liquid pump.

그러나,운전조건이 하나라도 충족되어 있지 않으면,프로그램에 의해 이상이 발생되어 있는 부분을 제1제어부(2)에서 표시부(9)를 통해 한글및 영문으로 표시하고 운전을 수행하지 않게 된다.However, if any one of the operating conditions is not satisfied, the part in which the abnormality is generated by the program is displayed in Korean and English through the display unit 9 in the first control unit 2 and the operation is not performed.

한편,기동이 완료되면,제2출력부(6),입출력부(8),표시부(9)를 통하여 그 상태를 표시하고,기기운전에 연동되어야 하는 보조기기(예를들어 급배기팬)를 제2출력부(6)를 통하여 운전시킨다.On the other hand, when the start is completed, the state is displayed through the second output unit 6, the input / output unit 8, the display unit 9, and the auxiliary device (for example, the supply / exhaust fan) which should be linked to the operation of the device. The operation is performed through the second output unit 6.

또한,제2출력부(6)를 통하여 운전되는 보조기기가 정상적으로 운전에 들어갔는지를 제2입력부(5)를 통하여 확인하고 확인결과 이상이 없으면,기억부(7)에 기억되어 있는 프로그램 순서에 따라 다음 동작을 수행한다.In addition, if it is confirmed through the second input unit 5 whether the auxiliary device operated through the second output unit 6 has been normally operated, and there is no abnormality as a result of the check, the program sequence stored in the storage unit 7 Therefore, perform the following operation.

그러나,제2입력부(5)를 통하여 확인결과 이상이 있을 때에는 입출력부(8)와 표시부(9)를 통하여 그 내용을 경보하고 기기는 제1제어부(2)에서 연산한 시간에 의해 정지운전상태로 들어간다.However, when there is an abnormality in the result of confirmation through the second input unit 5, the contents are alerted through the input / output unit 8 and the display unit 9, and the device is in the stop operation state by the time calculated by the first control unit 2. Enter

그리고 보조기기 운전이 완료되었으면,기억부(7)에 기억된 프로그램에 따라 연료제어변의 구동 허락 신호를 제2출력부(6) 또는 제1출력부(3)를 통하여 출력시킴과 동시에 제2출력부(6)를 통하여 냉매 펌프 기동신호를 출력시킨다.When the auxiliary device operation is completed, the driving permission signal of the fuel control valve is output through the second output unit 6 or the first output unit 3 according to the program stored in the storage unit 7 and at the same time, the second output. Through the unit 6, the refrigerant pump start signal is output.

이와같은 동작이 모두 완료되면,제1제어부(2)에서는 기억부(7)에 기억되어 있는 온도제어 프로그램에 따라 다음과 같은 순서로 온도제어를 수행하게 된다.When all such operations are completed, the first control unit 2 performs temperature control in the following order according to the temperature control program stored in the storage unit 7.

즉,제1제어부(2)에서는 입출력부(8)로부터 온도를 제어하고자 하는 목표치를 읽어 들여 목표치를 기억부(7)에 기억시키고 제1입력부(1)를 통하여 기기의 냉수온도를 읽어들인다.That is, the first control unit 2 reads the target value for controlling the temperature from the input / output unit 8, stores the target value in the storage unit 7, and reads the cold water temperature of the device through the first input unit 1.

따라서,제1제어부(2)에서는 기억부(7)에 기억된 목표치와 제1입력부(1)를 통하여 읽어들인 냉수온도를 비교하여 발생된 편차를 판단하고 그 편차량을 기억부(7)에 기억된 프로그램의 온도제어 연산식에 대입시켜 연산을 실행한다.Accordingly, the first control unit 2 compares the target value stored in the storage unit 7 with the cold water temperature read through the first input unit 1 to determine the deviation generated and stores the deviation amount in the storage unit 7. The operation is performed by substituting the stored temperature control equation of the stored program.

그리고 연산된 결과를 제1제어부(2)에서 제2제어부(4)로 전달하면 제2제어부(4)에서는 제1입력부(1)를 통하여 입력된 연료제어변의 현재의 개도율과 제1제어부(2)로부터 전달받은 연산결과를 비교하여 개도율의 연산결과가 일치하도록 제1또는 제2출력부(3)(6)를 통하여 연료제어변을 동작시키며,이와같은 과정을 기기운전이 정지될 때까지 자동반복한다.When the calculated result is transmitted from the first control unit 2 to the second control unit 4, the second control unit 4 transmits the current opening ratio of the fuel control valve input through the first input unit 1 and the first control unit ( Comparing the calculation result received from 2) and operating the fuel control valve through the first or second output unit (3) (6) to match the calculation result of the opening degree, when such operation is stopped Auto repeat until

이때,제1제어부(2)는 운전중 모든 입력장치로부터 전송되어 오는 신호를 연속적으로 확인하여 기억부(7)에 기억된 프로그램에 따라 적절한 제어동작을 수행하게 된다.At this time, the first control unit 2 continuously checks the signals transmitted from all the input devices during the operation, and performs the appropriate control operation according to the program stored in the storage unit 7.

따라서,운전자가 입출력부(8)에 위치한 정지스위치를 눌렀거나 입출력부(8)로부터 이상확인신호가 입력되면,즉시 연료제어변을 닫고 기억부(7)에 기억된 프로그램에 따라 이상의 종류변 우선순위를 판단하여 판단된 우선순위를 따라 기기의 운전정지를 수행한다.Therefore, when the driver presses the stop switch located in the input / output section 8 or the abnormality confirmation signal is input from the input / output section 8, immediately closes the fuel control valve and gives priority to the abnormal type valve according to the program stored in the storage section 7. Determines the priority and stops the operation of the device according to the determined priority.

이때,흡수액 펌프및 냉매 펌프,보조기기는 제1제어부(2)에서 연산한 최적의 시간마다 제2출력부(6)와 제1출력부(3)를 통하여 정지하게 된다.At this time, the absorbent liquid pump, the refrigerant pump, and the auxiliary device are stopped through the second output unit 6 and the first output unit 3 at the optimum time calculated by the first control unit 2.

이와같이 정지동작이 완료되면,기기의 운전이 완전히 정지하였음을 표시부(9)와 입출력부(8)의 램프를 통하여 운전자에게 경보한다.When the stop operation is completed in this manner, the driver is alerted via the lamps of the display unit 9 and the input / output unit 8 that the operation of the device is completely stopped.

한편,상기와 같은 본 발명은 빌딩 자동화에 대응하기 위하여 발명된 장치로서,중앙감시 제어변에 설치된 상위 컴퓨터와 본 발명의 장치를 상호 접속하면 중앙감시 제어변에서 기기를 운전하거나 정지시킬 수 있으며,기기의 모든 운전 데이타를 중앙 감시반에서 확인할 수 있게 된다.On the other hand, the present invention as described above is a device invented to cope with building automation, interconnecting the host computer and the apparatus of the present invention installed in the central monitoring control valve, it is possible to operate or stop the device in the central monitoring control valve, All operating data of the unit can be checked in the central station.

즉, 제1제어부(2)에 접속된 통신부(10)를 통하여 중앙 감시반의 상위 컴퓨터로부터 데이타를 전송받으면 제1제어부(2)에서는 기억부(7)에 기억된 통신 프로그램에 따라 제어동작을 실행시키게 된다.That is, when data is transmitted from the host computer of the central monitoring panel via the communication unit 10 connected to the first control unit 2, the first control unit 2 executes the control operation according to the communication program stored in the storage unit 7. Let's go.

그리고,통신부(10)에 프린터를 접속하고 프린터 명령을 입력시키면 제1제어부(2)에서는 기억부(7)에 기억된 프로그램에 따라 데이타를 프린터로 전송하게 된다.When the printer is connected to the communication unit 10 and a printer command is input, the first control unit 2 transmits data to the printer in accordance with the program stored in the storage unit 7.

본 발명에 의하면,흡수액 순환량을 최적제어할 수 있는 것으로,제1입력부(1)를 통하여 입력된 온도데이타를 기억부(7)에 기억된 연산식에 대입시켜 제1제어부(2)에서 연산을 수행하고 그 연산결과를 제1출력부(3)를 통하여 주파수 변환장치로 보낸다.According to the present invention, it is possible to optimally control the absorption liquid circulation amount, and the operation is performed in the first control unit 2 by substituting the temperature data input through the first input unit 1 into the equation stored in the storage unit 7. The calculation results are sent to the frequency converter via the first output unit 3.

그리고 흡수액 펌프는 주파수 변환장치에 접속되어 있어 주파수 변환장치의 주파수에 의해 흡수액 펌프의 회전수를 가감시킴으로써 흡수액의 순환량을 최적의 상태로 유지하여 기기의 효율을 증대시키게 된다.The absorption liquid pump is connected to the frequency converter so that the rotation speed of the absorption liquid pump is reduced by the frequency of the frequency converter to maintain the circulation amount of the absorption liquid in an optimal state, thereby increasing the efficiency of the device.

또한, 본 발명은,고장을 판단하여 경보해 주는 기능을 가진 것으로,입출력부(8)를 통하여 입력된 흡수액 펌프,냉매펌프,연료제어변 장비 기준 운전시간및 기동횟수와 제2입력부(5)를 통하여 입력된 흡수액 펌프,냉매 펌프 연료 제어변의 실제운전시간을 제1제어부(2)에서 비교판단하여 표시부(9)를 통하여 경보함으로써 운전자가 사전에 해당 부속장치를 정비할 수 있게 된다.In addition, the present invention, having a function to determine the failure and alarm, the absorbing liquid pump, refrigerant pump, fuel control valve equipment reference operation time and the start frequency and the second input unit 5 input through the input and output unit 8 By comparing the actual operating time of the absorbent liquid pump, the refrigerant pump fuel control valve input through the first control unit 2 and the alarm through the display unit 9, the driver can maintain the accessory in advance.

그리고 본 발명은 제1입력부(1)를 통하여 입력된 온도데이타를 기억부(7)에 기억된 프로그램 연산식에 대입하여 제1제어부(2)에서 연산한 후 흡수액의 농도가 기억부(7)에 기억된 기준치이상이면 제2출력부(6)또는 제1출력부(3)를 통하여 흡수액의 결정이 발생하지 않도록 연료제어변을 제어하게 된다.In the present invention, the temperature data input through the first input unit 1 is substituted into the program calculation formula stored in the storage unit 7, and the concentration of the absorbing liquid is calculated by the first control unit 2. The fuel control valve is controlled so that the determination of the absorbing liquid does not occur through the second output unit 6 or the first output unit 3 when the reference value is equal to or larger than the reference value stored in the control unit.

또한,제1입력부(1)를 통하여 입력된 온도데이타가 기억부(7)에 기억된 프로그램의 이상판단기준치와 비교하여 이상이라고 판단되면 이상이 발생한 온도센서의 종류를 재확인하여 기억부(7)에 기억된 이상발생시 처리 프로그램에 따라 제어동작을 실행하고 입출력부(8),표시부(9)를 통하여 이상상태를 운전자에게 경보한다.In addition, if it is determined that the temperature data input through the first input unit 1 is abnormal in comparison with the abnormal determination reference value of the program stored in the storage unit 7, the type of temperature sensor in which the abnormality has occurred is reconfirmed and stored in the storage unit 7. The control operation is executed in accordance with the processing program when an abnormality is stored in the memory, and the driver is alerted to the abnormal state through the input / output unit 8 and the display unit 9.

본 고안 흡수식 냉동기기 제어장치에 의하면,기기의 운전상태를 감시하여 운전자에게 알려주는 경보기능을 가짐은 물론,용액펌프의 수명을 알려주는 예지기능과 이상상태 발생시 이상의 종류를 판단하여 판단된 내용에 따라 기기를 최적으로 정지시키는 최적운전기능,온도제어 연산식을 이용한 정확한 온도제어 기능등을 구비하여 기기의 신뢰성을 향상시킬 수 있음은 물론 사용자의 운전 메뉴얼이 없어도 표시부를 통하여 운전을 편리하게 수행할 수 있는 효과가 있는 것이다.According to the present invention, the absorption refrigeration apparatus control device has an alarm function that monitors the operation state of the device and informs the driver, as well as a predictive function that informs the life of the solution pump and the type of abnormality when the abnormal condition occurs. Therefore, it is possible to improve the reliability of the device by providing the optimal operation function to stop the device optimally and the accurate temperature control function using the temperature control calculation formula, and to perform the operation conveniently through the display without the user's operation manual. It can be effective.
