Description

왕복동식 압축기의 운전제어방법{DRIVE CONTROL METHOD FOR RECIPROCATING COMPRESSOR}DRIVE CONTROL METHOD FOR RECIPROCATING COMPRESSOR}

본 발명은 왕복동식 압축기의 운전제어방법에 관한 것으로, 특히 기동시 일정 시간동안 저 스트로크로 운전을 수행하여 정확하게 TDC=0인 지점을 검출하도록 한 왕복동식 압축기의 운전제어방법에 관한 것이다.The present invention relates to an operation control method of a reciprocating compressor, and more particularly, to an operation control method of a reciprocating compressor that detects a point where TDC = 0 by performing operation at a low stroke for a predetermined time during startup.

일반적인 왕복동식 압축기는, 다상의 고정자에 권취된 코일에 공급되는 전원을 스위칭소자를 이용하여 단속함으로써, 회전 토오크(TORQUE)를 발생시키게 되는데, 회전자와 고정자간의 여자상태를 순차적으로 가변시킴으로써, 자기 흡입력에 의하여 정방향 회전 토오크를 발생시킬 수 있다.In general, a reciprocating compressor generates a torque by interrupting the power supplied to a coil wound around a multi-phase stator by using a switching element. By sequentially changing the excitation state between the rotor and the stator, The forward rotational torque can be generated by the suction force.

도1은 일반적인 왕복동식 압축기의 운전제어장치에 대한 구성을 보인 블록도로서, 이에 도시된 바와같이 스트로크 지령치에 따라, 내부 모터에 인가되는 전압에 의해, 피스톤이 상하운동으로 스트로크를 가변시켜 냉력을 조절하는 왕복동식 압축부(L.COMP)와; 인가전압에 의해 스트로크를 증가시킴에 따라, 상기 왕복동식 압축부(L.COMP)에 발생하는 전압을 검출하는 전압검출부(30)와; 인가전압에 의해 스트로크를 증가시킴에 따라, 상기 왕복동식 압축부(L.COMP)에 인가되는 전류를 검출하는 전류 검출부(20)와; 상기 전압검출부(30) 및 전류 검출부(20)로부터 검출된 전압과 전류로 스트로크를 계산하고, 그 스트로크를 스트로크지령치와 비교하여 그에 따른 스위칭제어신호를 출력하는 마이크로컴퓨터(40)와; 상기 마이크로컴퓨터 (40)의 스위칭제어신호에 따라, 교류전원을 트라이악(Tr1)으로 단속시켜 상기 왕복동식 압축부(L.COMP)에 전압을 인가하는 전기회로부(10)로 구성되고, 이와같이 구성된 종래 장치의 동작을 설명한다.1 is a block diagram showing a configuration of an operation control device of a general reciprocating compressor. As shown in FIG. 1, the piston changes the stroke in vertical motion by the voltage applied to the internal motor according to the stroke command value. A reciprocating compression unit (L.COMP) for adjusting; A voltage detector (30) which detects a voltage generated in the reciprocating compression section (L.COMP) as the stroke is increased by an applied voltage; A current detector 20 which detects a current applied to the reciprocating compressor L.COMP as the stroke is increased by an applied voltage; A microcomputer (40) for calculating a stroke from the voltage and current detected by the voltage detector (30) and the current detector (20), comparing the stroke with a stroke command value, and outputting a switching control signal accordingly; In accordance with the switching control signal of the microcomputer 40, it consists of an electrical circuit section 10 for interrupting the AC power to the triac (Tr1) to apply a voltage to the reciprocating compression section (L.COMP), and thus The operation of the conventional apparatus will be described.

먼저, 왕복동식 압축부(L.COMP)는 사용자에 의해 설정된 스트로크 지령치에 따른 인가전압에 의해, 피스톤이 상하 운동되고, 이로 인해 스트로크가 가변되어 냉력을 조절한다.First, the reciprocating compression section (L.COMP), the piston is moved up and down by the applied voltage according to the stroke command value set by the user, thereby the stroke is variable to adjust the cooling force.

한편, 전기회로부(10)의 트라이악(Tr1)은 마이크로컴퓨터(40)의 스위칭제어신호에 의해 턴온 주기가 길어짐에 의해 스트로크가 증가되는데, 이때 왕복동식 압축부(L.COMP)의 모터(M)에 인가되는 인가전압과 전류를 각기 전압검출부(30)와 전류검출부(20)에서 검출하여 이를 마이크로컴퓨터(40)에 인가한다.Meanwhile, the stroke of the triac Tr1 of the electric circuit unit 10 is increased due to a long turn-on period due to the switching control signal of the microcomputer 40, wherein the motor M of the reciprocating compressor L.COMP is increased. The voltage and the current applied to the) are detected by the voltage detector 30 and the current detector 20, and applied to the microcomputer 40.

그러면, 상기 마이크로컴퓨터(40)는 상기 전압검출부(30)와 전류검출부(20)로부터 검출된 인가전압과 전류를 이용하여 스트로크를 계산한후, 이 스트로크를 스트로크지령치와 비교하여 그에 따라 스위칭제어신호를 출력한다.Then, the microcomputer 40 calculates a stroke using the applied voltage and current detected from the voltage detector 30 and the current detector 20, and compares the stroke with the stroke command value and accordingly switches the control signal. Outputs

즉, 상기 마이크로컴퓨터(40)는 계산된 스트로크가 스트로크 지령치 보다 작으면, 트라이악(Tr1)의 온주기를 길게 하는 스위칭제어신호를 출력하여 왕복동식 압축부(L.COMP)에 인가되는 전압을 증가시킨다.That is, when the calculated stroke is smaller than the stroke command value, the microcomputer 40 outputs a switching control signal for lengthening the on-cycle of the triac Tr1, thereby converting the voltage applied to the reciprocating compressor L.COMP. Increase.

상술한 바와 달리, 상기 마이크로컴퓨터(40)는 계산된 스트로크가 스트로크 지령치보다 크면, 트라이악(Tr1)의 온주기를 짧게 하는 스위칭제어신호를 출력하여 왕복동식 압축부(L.COMP)에 인가되는 전압을 감소시킨다.Unlike the above, when the calculated stroke is larger than the stroke command value, the microcomputer 40 outputs a switching control signal for shortening the on-cycle of the triac Tr1 and is applied to the reciprocating compressor L.COMP. Reduce the voltage.

여기서, 상술한 바와 같은 종래 장치는, 도2와 같이, 초기 기동시 스트로크를 서서히 증가시켜 'TDC=O'인 지점까지 스트로크가 증가되면 그 시점의 스트로크를 유지하도록 제어한다.Here, the conventional apparatus as described above, as shown in Fig. 2, when the initial start-up gradually increases the stroke is controlled to maintain the stroke at that time if the stroke is increased to the point of 'TDC = O'.

이렇게, 스트로크가 '0'에서 부터 'TDC=O'인 지점까지 급격히 증가하게 되면, 왕복동식 압축부의 흡입압과 토출압이 급변하게 되어 'TDC=O'인 지점을 찾지 못하는 경우가 발생하는데, 만약 과스트로크가 발생하면 압축기가 파손되고, 저스트로크이면 냉력이 부족하게 되는 문제점이 있다.In this way, if the stroke is rapidly increased from '0' to the point of 'TDC = O', the suction and discharge pressures of the reciprocating compression unit are suddenly changed, and thus, the point of 'TDC = O' cannot be found. If the overstroke occurs, the compressor is broken, if the low stroke there is a problem that the cold power is insufficient.

또한, 스트로크와 부하의 급변으로 인하여 변동 소음이 크게 발생하는 문제점이 있다.In addition, there is a problem that large fluctuation noise occurs due to sudden changes in stroke and load.

본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로, 기동시 일정 시간동안 저 스트로크로 운전을 수행하여 싸이클을 안정시킨후, TDC=0인 지점을 정확하게 검출하도록 한 왕복동식 압축기의 운전제어방법을 제공함에 그 목적이 있다.The present invention has been made to solve the above problems, the operation control method of the reciprocating compressor to accurately detect the point of TDC = 0 after performing the operation at a low stroke for a certain time during start-up, to stabilize the cycle The purpose is to provide.

상기와 같은 목적을 달성하기 위한 본 발명은, 왕복동식 압축기에 있어서,초기 기동되면, 왕복동식 압축기의 스트로크를 제1 기준시간에 도달할 때까지 서서히 증가시키면서, 운전시간이 제1 기준시간에 도달하였는지를 판단하는 제1 과정과; 상기 판단결과, 운전시간이 상기 제1 기준시간에 도달하면, 그 시점의 스트로크를, 제2 기준시간에 도달할때까지 유지시키는 제2 과정과; 상기 제2 과정의 스트로크 운전시간이, 제2 기준시간에 도달하면, 다시 스트로크를 증가시켜 TDC=0인 지점의 스트로크를 검출한후, 그 검출한 TDC=0인 스트로크로 왕복동식 압축기를 운전하는 제3 과정으로 수행함을 특징으로 한다.The present invention for achieving the above object, in the reciprocating compressor, when initially started, the operation time reaches the first reference time while gradually increasing the stroke of the reciprocating compressor until the first reference time is reached. A first process of judging whether it has been done; A second step of, if the operation time reaches the first reference time as a result of the determination, maintaining the stroke at that time until the second reference time is reached; When the stroke operation time of the second process reaches the second reference time, the stroke is increased again to detect the stroke at the point of TDC = 0, and then the reciprocating compressor is operated with the detected stroke of TDC = 0. Characterized in that the third process.

이하, 본 발명에 의한 왕복동식 압축기의 운전제어방법에 대한 작용 및 효과를 첨부한 도면을 참조하여 상세히 설명한다.Hereinafter, the operation and effect of the operation control method of the reciprocating compressor according to the present invention will be described in detail with reference to the accompanying drawings.

본 발명 왕복동식 압축기의 운전제어방법이 적용되는 장치는 도1과 동일하고, 도3은 본 발명 왕복동식 압축기의 운전제어방법에 대한 동작흐름도로서, 이에 도시한 바와같이, 사용자에 의해 기동되면, 스트로크를 일정시간에 도달할 때까지 서서히 증가시키는 제1 과정과; 일정시간에 도달하면, 그 시점의 스트로크로 소정 시간동안 운전하는 제2 과정과; 상기 소정시간이 지나면, 다시 스트로크를 증가시켜 TDC=0인 지점의 스트로크 검출한후, 그 TDC=0인 스트로크로 운전하는 제3 과정으로 이루어지고, 이와같은 본 발명의 동작을 설명한다.Apparatus to which the operation control method of the reciprocating compressor of the present invention is applied is the same as that of FIG. 1, and FIG. 3 is an operation flow chart of the operation control method of the reciprocating compressor of the present invention. Gradually increasing the stroke until reaching a certain time; A second process of driving for a predetermined time at the stroke at that time when the predetermined time is reached; After the predetermined time has elapsed, a third step is performed in which the stroke is increased again to detect the stroke at the point where TDC = 0, and the operation is performed at the stroke at the TDC = 0, and the operation of the present invention will be described.

먼저, 발명은, 도4와 같이 초기 기동시, 스트로크를 증가시키다가 일정 시점에 도달하면 그 스트로크를 유지하여 압축기를 운전시킨후, 다시 스트로크를 증가시켜 TDC=0인 지점에서의 스트로크를 검출한후, 그 TDC=0인 지점의 스트로크로 압축기를 운전시키는데,이를 상세히 설명한다.First, as shown in Fig. 4, when the initial start is increased as shown in Fig. 4, when the stroke reaches a predetermined time point, the compressor is operated by maintaining the stroke and then increasing the stroke to detect the stroke at the point where TDC = 0. Thereafter, the compressor is operated with the stroke at the point where TDC = 0, which will be described in detail.

우선, 실험에 의해, 싸이클이 안정되기 위한 제1,제2 기준시간을 기설정하여 롬에 저장한다.First, by experiment, the first and second reference times for stabilizing the cycle are preset and stored in the ROM.

이후, 왕복동식 압축부(L.COMP)가, 사용자에 의해 기동되면, 스트로크 지령치에 따른 인가전압에 의해, 피스톤이 상하 운동되고, 이로 인해 스트로크가 서서히 증가되다가 제1 기준시간에 도달하면 그 시점의 스트로크로 운전되다가,제2 기준시간이 지난후, 다시 가변되어 냉력을 조절한다.Subsequently, when the reciprocating compression section L.COMP is started by the user, the piston moves up and down by the applied voltage according to the stroke command value, whereby the stroke gradually increases and then reaches the first reference time. After the second reference time has elapsed, it is adjusted again to adjust the cooling power.

이때, 전기회로부(10)의 트라이악(Tr1)은 마이크로컴퓨터(40)의 스위칭제어신호에 의해 턴온 주기가 길어짐에 의해 스트로크가 증가되는데, 이때 상기 마이크로컴퓨터(40)는 초기 설정된 제1 기준시간에 도달하면 그 시점의 스트로크에 해당되는 스위칭제어신호를 트라이악(Tr1)에 인가한다.In this case, the stroke of the triac Tr1 of the electric circuit unit 10 is increased due to a long turn-on period due to the switching control signal of the microcomputer 40. At this time, the microcomputer 40 initially sets the first reference time. When is reached, the switching control signal corresponding to the stroke at that time is applied to the triac Tr1.

여기서, 상기 마이크로컴퓨터(40)는, 제2 기준시간에 도달할때까지 상기 스위칭제어신호로 트라이악(Tr1)의 온/오프를 제어하여 현재 스트로크를 유지하다가, 그 제2 기준시간이 지나면 다시 스위칭제어신호의 턴온주기를 길게하여 스트로크를 증가시킨다.Here, the microcomputer 40 maintains the current stroke by controlling the on / off of the triac Tr1 with the switching control signal until the second reference time is reached, and then again after the second reference time passes. The turn-on period of the switching control signal is lengthened to increase the stroke.

이후, 상기 마이크로컴퓨터(40)는 TDC=0인 스트로크를 검출한후, 그 TDC=0인 스트로크시의 스위칭제어신호로 트라이악(Tr1)의 온/오프를 제어하여 왕복동식 압축부(L.COMP)를 구동한다.Thereafter, the microcomputer 40 detects a stroke having a TDC = 0, and then controls the on / off of the triac Tr1 by a switching control signal at the stroke having the TDC = 0, thereby reciprocating the compression unit L. COMP).

다시 말해서, 본 발명은 초기 기동시, 압축기의 흡입압과 토출압이 급변함으로 인한 싸이클의 불안정을 제거하기 위하여, 일정시간동안 저스트로크로 운전하여 싸이클이 안정되면 TDC=0인 스트로크를 검색함으로써, 정확하게 TDC=0인 스트로크를 검출한다.In other words, in order to eliminate the instability of the cycle due to the sudden change in the suction and discharge pressures of the compressor during the initial start-up, the present invention is operated by a low stroke for a predetermined time to search for a stroke of TDC = 0 when the cycle is stable. Detects a stroke with exactly TDC = 0.

이상에서 상세히 설명한 바와같이 본 발명은, 기동시 일정 시간동안 저 스트로크로 운전을 수행하여 싸이클을 안정시킨후, TDC=0인 지점을 정확하게 검출함으로써, 과스트로크나 저스트로크를 방지함과 아울러 스트로크와 부하의 급변으로 인한 변동소음을 최소화하는 효과가 있다.As described in detail above, the present invention performs the operation with a low stroke for a predetermined time during start-up, stabilizes the cycle, and accurately detects the point where TDC = 0, thereby preventing overstroke and low stroke, It is effective to minimize fluctuation noise caused by sudden change of load.
