도 1의 본 발명에 따른 히트펌프를 이용한 전기발전장치의 계통도로서, 도 1에 도시된 바와 같이, 어큐뮬레이터(50), 압축기(10) 및 사방밸브(60)를 포함하는 히트펌프(100)이다.1, a heat pump 100 including an accumulator 50, a compressor 10, and a four-way valve 60, as shown in FIG. 1, is a flow diagram of an electric power generating apparatus using a heat pump according to the present invention .

본 발명에 적용된 히트펌프(100)는 공지의 히트펌프(100) 구성인 압축기(10), 응축기(20), 팽창밸브(30), 증발기(40)를 포함하고 있으며, 압축기(10)를 통해관 작동유체는 냉매로서, 고온, 고압의 기체상태의 고압가스 상태이며, 응축기(20)를 지나면서 저온, 고압의 액체상태가 되고, 팽창밸브(30)를 지나면서 저온, 저압의 액체상태가 되며, 증발기(40)를 통과하면서 열을 빼앗거나 뺏겨 저압가스가 되어 다시 압축기(10)로 인입된다.The heat pump 100 applied to the present invention includes a compressor 10, a condenser 20, an expansion valve 30 and an evaporator 40 constituting a known heat pump 100, The tube working fluid is a refrigerant, which is a high-pressure gaseous state in a gaseous state at a high temperature and a high pressure, passes through the condenser 20 and becomes a low-temperature and high-pressure liquid state. The refrigerant passes through the evaporator 40, and the heat is taken or lost to be a low-pressure gas and then introduced into the compressor 10 again.

이때, 전기적 신호에 의해 작동하는 사방밸브(60)는 압축기(10)와 응축기(20), 증발기(40)의 배관 상에 설치되어 있으며, 여기에 다시 별도의 배관으로 연결된 에큐뮬레이터(50)가 설치되어 있다. 이러한 사방밸브(60)의 선택적 개폐에 따라 하절기에는 응축기(20) 냉방기로, 동절기에는 증발기(40)가 난방기의 기능으로 사용된다.The four-way valve 60 operated by the electrical signal is installed on the piping of the compressor 10, the condenser 20 and the evaporator 40 and is connected to the accumulator 50, Respectively. In accordance with the selective opening and closing of the four-way valve 60, the evaporator 40 is used as the function of the radiator in the summer and the radiator 40 in the winter season.

특히, 어큐뮬레이터(50)로는 압축기(10)로 저압가스가 인입되는 인입배관 외 별도로 설치되어 순환된 저압가스가 어큐뮬레이터(50)로 배기되는 리턴배관(R)이 설치되어 있다.Particularly, the accumulator 50 is provided with a return pipe R, which is installed separately from the inlet pipe through which the low-pressure gas is introduced into the compressor 10, and the circulated low-pressure gas is exhausted to the accumulator 50.

이 리턴배관(R)은 후술하는 복동실린더()를 작동시킨 후 순환하여 저압으로 배기되는 저압가스를 어큐뮬레이터(50)를 통해 압축기(10)로 공급하는 역할을 수행한다.The return pipe R serves to supply a low-pressure gas circulated after being operated by a double-acting cylinder (to be described later) and discharged at a low pressure to the compressor 10 through the accumulator 50.

다시, 압축기(10)로는 압축기(10)에서 배출된 고압가스 흐르고, 사방밸브(10)로 연결된 배관 상에서 분기되어 고압가스를 공급하는 공급배관(A)이 설치되어 있고, 이러한 리턴배관(R)과 공급배관(A)은 솔레노이드밸브(70)와 연결되어 있다.The high pressure gas discharged from the compressor 10 is supplied to the compressor 10 and a supply pipe A for branching on the pipe connected to the four-way valve 10 to supply high-pressure gas is provided. And the supply pipe (A) are connected to the solenoid valve (70).

도 2의 a와 b는 본 발명에 적용된 솔레노이드밸브의 작동상태를 보여주는 도면들로서, 도 1과 도 2의 a와 b를 참조하면, 본 발명에 적용된 솔레노이드밸브(70)는 방향제어가 가능한 밸브로서, 솔레노이드가 양단에 설치된 양 솔레노이드밸브가 적용되는 것이 바람직하며, 특히, 도 2의 a와 같이 압축기(10)를 통해 인입되는 고압가스를 복동실린더(80)에 공급하여 피스톤(82)을 상승시키고, 저압가스를 배기시키는 역할을 수행한다.2A and 2B are views showing the operating state of the solenoid valve applied to the present invention. Referring to FIGS. 1 and 2A and 2B, the solenoid valve 70 according to the present invention is a valve capable of controlling the direction , A solenoid valve provided at both ends of the solenoid is preferably applied. In particular, as shown in FIG. 2 (a), high pressure gas introduced through the compressor 10 is supplied to the double acting cylinder 80 to raise the piston 82 , And discharges the low-pressure gas.

또한, 도 2의 b와 같이 피스톤(82)을 하강시키기 위해서 다시, 압축기(10)를 통과한 고압가스를 복동실린더(80)에 공급하여 피스톤(82)을 하강시키고, 저압가스를 배기시킨다.2B, a high-pressure gas having passed through the compressor 10 is supplied to the double-acting cylinder 80 to descend the piston 82 to lower the piston 82, thereby exhausting the low-pressure gas.

이러한 솔레노이드밸브(70)의 작동은 피스톤(82)의 상사점과 하사점을 감지하도록 복동실린더(80)에는 센서(84)가 설치되어 있으며, 이 센서(84)들에 의해서 감지되며, 감지된 신호를 솔레노이드로 보내 방향제어밸브를 작동시켜 도 2의 a와 b와 같은 작동을 수행한다.The operation of the solenoid valve 70 is such that a sensor 84 is installed in the double acting cylinder 80 to sense the top dead center and the bottom dead center of the piston 82 and is sensed by the sensors 84, A signal is sent to the solenoid to actuate the directional control valve to perform the operations as in FIGS. 2A and 2B.

전술한 바와 같이, 배기된 저압가스는 리턴배관(R)으로 이동하며, 고압가스는 공급배관(A)으로 공급된다.As described above, the evacuated low-pressure gas moves to the return pipe R, and the high-pressure gas is supplied to the supply pipe A.

위와 같이, 본 발명은 히트펌프(HP)의 고압가스를 이용하여 복동실린더(80)를 작동시켜 냉매인 작동유체의 운동에너지를 이용할 수 있다.As described above, the present invention can use the kinetic energy of the working fluid, which is a refrigerant, by operating the double-acting cylinder 80 using the high-pressure gas of the heat pump HP.

다시, 복동실린더(80)의 작동을 통해 발전하는 과정을 설명한다.The process of generating electricity through the operation of the double-acting cylinder 80 will be described again.

도 3은 본 발명에 적용된 복동 실린더를 통해 기어장치가 회전하는 상태를 보여주는 작동도이다.3 is an operation diagram showing a state in which a gear device is rotated through a double acting cylinder applied to the present invention.

도 1 내지 도 3을 참조하면, 본 발명은 복동식 실린더(80)의 왕복운동을 회전운동으로 변환시켜 발전기(100)를 작동시키는 기어장치(90)를 포함하고 있다.1 to 3, the present invention includes a gear device 90 for converting a reciprocating motion of a double-acting cylinder 80 into a rotational motion to operate the generator 100.

본 발명에 적용된 기어장치(90)는 피스톤(82)에서 연장된 피스톤로드(86)와 회동가능하게 결합된 커넥팅로드(92)를 포함하고 있다.The gearing 90 applied to the present invention includes a connecting rod 92 pivotally coupled to a piston rod 86 extending from the piston 82.

피스톤로드(86)와 커넥팅로드(92)의 결합은 회동가능하게 동요각(動搖角)을 갖고 있다. 이 동요각에 의해서 피스톤로드(86)의 상하 왕복운동시 피스톤로드(86)에서 발생할 수 있는 휨 등에 의한 변형을 방지하나, 그렇다고 이러한 회동결합에만 한정되지 않고, 동요각 없이 결합될 수도 있다.The engagement between the piston rod 86 and the connecting rod 92 has a swinging angle. The piston rod 86 is prevented from being deformed due to a bending or the like which may occur in the piston rod 86 during up-and-down reciprocating movement of the piston rod 86 by this swaying angle, but it is not limited to such pivotal connection.

본 발명은 커넥팅로드(92)의 왕복운동을 회전운동으로 변환하도록 기어가 형성된 플라이휠(94)의 일측과 결합되어 있다.The present invention is combined with one side of a flywheel 94 in which a gear is formed to convert the reciprocating motion of the connecting rod 92 into rotational motion.

다시, 커넥팅로드(92)의 왕복운동을 회전토크로 변환시키기 위하여 커넥팅로드(92)와 플라이휠(94) 사이에는 크랭크축(98)이 결합되어 있다.Again, a crankshaft 98 is coupled between the connecting rod 92 and the flywheel 94 to convert the reciprocating motion of the connecting rod 92 into rotational torque.

플라이휠(92)은 그 외면으로 기어가 형성되어 있으며, 상기 동요각에 의해서 사점(dead point)을 통과하기 쉽게하고, 또 회전력을 평균화한다. The flywheel 92 has gears formed on its outer surface, which makes it easier for the dead point to pass through the swaying angle and averages the rotational force.

본 발명은 플라이휠(92)과 치합되어 회전하는 피니언(96)이 설치되고, 피니언(96)은 증속기(110)에 의해서 더욱 가속된 후 다시 발전기(100)와 연결되어 최종적으로 발전하게 된다.The present invention is provided with a pinion 96 that rotates in conjunction with a flywheel 92. The pinion 96 is further accelerated by the gearbox 110 and then connected to the generator 100 to be finally developed.

본 발명에 있어서 피니언(96)은 플라이휠(92)보다 상대적으로 작은 지름을 가지고 있어 그 회전속도가 가속된다.In the present invention, the pinion 96 has a smaller diameter than the flywheel 92, and the rotational speed thereof is accelerated.

이러한 피니언(96)의 축은 증속기(110)와 결합되어 가속된 피니언(96)의 회전을 1:10, 1:20의 비율과 같이 증속하여 발전기에서 필요로 하는 회전력을 발생시킨다.
The axis of the pinion 96 is coupled with the speed reducer 110 to increase the rotation of the accelerated pinion 96 at a ratio of 1:10 and 1:20 to generate a rotational force required by the generator.

본 발명은 그 정신 또는 주요한 특징으로부터 일탈하는 일없이, 다른 여러 가지 형태로 실시할 수 있다. 그 때문에, 전술한 실시예는 모든 점에서 단순한 예시에 지나지 않으며, 한정적으로 해석해서는 안된다. 본 발명의 범위는 특허청구의 범위에 의해서 나타내는 것으로써, 명세서 본문에 의해서는 아무런 구속도 되지 않는다. 다시, 특허청구범위의 균등 범위에 속하는 변형이나 변경은, 모두 본 발명의 범위 내의 것이다.
The present invention may be embodied in many other forms without departing from the spirit or essential characteristics thereof. Therefore, the above-described embodiments are merely examples in all respects, and should not be construed restrictively. The scope of the present invention is indicated by the appended claims, and the present invention is not restricted by the specification. Modifications and variations falling within the scope of the appended claims all fall within the scope of the present invention.
