집열장치(100)는 태양 에너지를 집광하여 열매체유를 고온으로 가열하고, 상기 집열장치(100)는 열매체유배관(150)을 통해 축열조(200) 내부의 중간에 위치한 열교환기(210a)에 연결되어, 열매체유는 집열장치(100)와 축열조(200)를 순환하면서 집열장치(100)에서 고온으로 가열되고 축열조(200)에서 물과의 열교환에 의해 온수를 만든다.The heat collecting device 100 collects solar energy to heat the heat medium oil to a high temperature, and the heat collecting device 100 is connected to a heat exchanger 210a located in the middle of the heat storage tank 200 through the heat medium oil pipe 150. Thus, the heat medium oil is heated to a high temperature in the heat collecting device 100 while circulating the heat collecting device 100 and the heat storage tank 200 to make hot water by heat exchange with water in the heat storage tank 200.

이때 축열조(200)에서 물과 열교환에 사용된 열매체유를 집열장치(100)에 순환하는 열매체유배관(150)에는 열매체유 순환펌프(152)가 구비되며, 열매체유로는 예를 들어 합성 열매체유인 Therminol 55가 사용된다.At this time, the heat medium oil pipe 150 circulating the heat medium oil used for heat exchange with water in the heat storage tank 200 to the heat collecting device 100 is provided with a heat medium oil circulation pump 152, and the heat medium oil is, for example, a synthetic heat medium oil. Therminol 55 is used.

상기 집열장치(100)에 추적(tracking)수단(160) 즉, 상기 집열장치(100)의 본체(102)에 고정되어 집열관(110)을 수평방향으로 회전하는 수평 회전부(162)와, 상기 집열관(110)의 경사각을 조절하는 경사각 조절부(164) 및 내부에 집속되는 태양열의 온도를 감지하여 태양의 이동 궤도를 추적할 수 있도록 하는 태양추적센서(166)를 구비하여, 태양의 이동 궤적을 따라가면서 집열관(110)의 수평 회전과 경사각이 조절된다.A horizontal rotating part 162 fixed to a tracking means 160 to the heat collecting device 100, that is, fixed to the main body 102 of the heat collecting device 100, to rotate the heat collecting pipe 110 in a horizontal direction; It is equipped with an inclination angle adjusting unit 164 for adjusting the inclination angle of the heat collecting pipe 110 and a solar tracking sensor 166 for detecting the temperature of the solar heat focused therein and tracking the movement trajectory of the sun.

고정식 집열장치보다는 상기 추적수단(160) 설치로 인해 집광(집열) 효율을 높일 수 있다.Rather than a stationary collector, the tracking means 160 may be installed to increase the light collecting efficiency.

상기 축열조(200) 내부의 아래에 위치한 열교환기(210b)는 냉동장치(300)의 냉매순환배관(350)으로 연결되어 냉동장치(300)의 응축기(320)에서 대기중으로 버려지는 응축열이 축열조(200)에 공급되어 물과 열교환한다.The heat exchanger 210b located below the heat storage tank 200 is connected to the refrigerant circulation pipe 350 of the refrigerating device 300, so that the heat of condensation that is discarded into the air from the condenser 320 of the freezing device 300 is stored in the heat storage tank ( And heat exchange with water.

즉, 축열조(200) 하부 물의 온도는 냉동장치(300)에 의해 유지를 하고 상부 물의 온도는 태양열을 이용하여 승온하게 된다.That is, the temperature of the lower water of the heat storage tank 200 is maintained by the refrigerating device 300, and the temperature of the upper water is increased by using solar heat.

이렇게 축열조 내부의 물이 축열조(200)에 공급된 열(응축열과 태양열)과 열교환기(210a,210b)에서의 열교환에 의해 온수가 되고 이 온수를 공기조화기(400)와 연계함으로써 에너지를 절감할 수 있다.Thus, the water inside the heat storage tank becomes hot water by heat (condensation heat and solar heat) supplied to the heat storage tank 200 and heat exchange in the heat exchangers 210a and 210b, and saves energy by linking the hot water with the air conditioner 400. can do.

믹스실(420)에서는 실내 순환공기와 외부의 신선한 공기가 유입되어 혼합되며, 믹스실(420) 후단에 설치된 공기여과기(430)를 통해 공기가 여과된다.In the mix chamber 420, indoor circulation air and fresh air from outside are introduced and mixed, and the air is filtered through an air filter 430 installed at the rear of the mix chamber 420.

상기 여과된 공기는 냉각코일(440)에 의해 냉각 및 제습되고 가열코일(450)에 의해 가열되며, 이때 냉각 및 가열코일(440,450)은 열전달 능력을 향상시키기 위해 동관 외부에 알루미늄 핀을 강제적 확관으로 밀착시켜 제작한다.The filtered air is cooled and dehumidified by the cooling coil 440 and heated by the heating coil 450, wherein the cooling and heating coils 440 and 450 are forcibly expanded with aluminum fins outside the copper pipe to improve heat transfer capability. Produce it in close contact.

냉동장치(300)의 팽창밸브(330)를 통과한 저온저압의 액체냉매가 냉각코일(440)의 동관에 공급되는 경우 여과된 공기와 열교환되면서 공기는 냉각 및 제습되고, 냉매는 저온저압의 기체로 상변환되어 냉매순환배관(350)을 통해 냉동장치(300)의 압축기(310)에 공급된다.When the low temperature low pressure liquid refrigerant passing through the expansion valve 330 of the refrigerating device 300 is supplied to the copper tube of the cooling coil 440, the air is cooled and dehumidified while being exchanged with the filtered air, and the refrigerant is a low temperature low pressure gas. It is phase-converted to and is supplied to the compressor 310 of the refrigerating device 300 through the refrigerant circulation pipe 350.

이때 사용되는 냉매는 성능에 따라 R-22나 그 대체 냉매가 사용된다.At this time, the refrigerant used is R-22 or an alternative refrigerant depending on the performance.

상기 가열코일(450)의 동관이 축열조(200)와 난방배관(220)으로 연결되어 상기 축열조(200)의 온수가 가열코일(450)에 공급되는 경우, 냉각된 공기와 열교환되면서 공기는 가열되어 가습기(460) 쪽으로 이동하고 온수는 냉각되어 난방순환펌프(240)에 의해 다시 축열조(200)에 공급 순환된다.When the copper pipe of the heating coil 450 is connected to the heat storage tank 200 and the heating pipe 220 so that hot water of the heat storage tank 200 is supplied to the heating coil 450, the air is heated while heat-exchanging with the cooled air. Moved toward the humidifier 460 and the hot water is cooled and supplied to the heat storage tank 200 again by the heating circulation pump 240.

상기 가열코일(450)을 통해 승온된 공기는 가습기(460)에 의해 가습되어 습도가 증가된 채 실내측 토출구에 설치된 송풍기(470)를 통해 실내에 공급된다.The air heated by the heating coil 450 is humidified by the humidifier 460 and supplied to the room through the blower 470 installed at the indoor outlet while the humidity is increased.

만일 실내의 상대습도가 목표치보다 높은 경우에는 정상적인 냉각 제습 작동을 통해 실내의 상대습도를 낮추면 된다.If the relative humidity in the room is higher than the target value, lower the relative humidity in the room through normal cooling dehumidification operation.

상기 냉동장치(300)는 압축기(310), 응축기(320), 팽창밸브(330), 유분리기(340) 및 액분리기(360)를 포함하여 구성되고 냉매순환배관(350)을 통해 연결된다.The refrigerating device 300 includes a compressor 310, a condenser 320, an expansion valve 330, an oil separator 340 and a liquid separator 360 and is connected through a refrigerant circulation pipe 350.

압축기(310)는 증발된 R-22나 그 대체 냉매 가스를 고온고압의 기체상태로 압축한다.The compressor 310 compresses the evaporated R-22 or its replacement refrigerant gas into a gaseous state of high temperature and high pressure.

일반적인 냉동장치(300)에서 냉매는 배관 내를 순환하면서 증발기에서 열교환후 저온저압의 기체로 나와 압축기(310)에 흡인된 후. 고온고압의 가스상태가 되어 대기중의 공기와 응축기(320)에서 열교환 응축되어 대기중에서 이 열이 버려지나, 본 발명에서는 축열조(200)의 하부로 보내져 낮은 온도의 물과 열교환되어 1차로 버려지는 열을 회수하고, 이를 축열조(200) 하부의 열교환기(210b)에서 열교환한 후 액체냉매를 응축기(320)로 보낸다.In the general refrigerating device 300 after the refrigerant is circulated in the pipe and the heat exchange in the evaporator after the low-temperature low-pressure gas is sucked into the compressor (310). The high-temperature, high-pressure gas state is heat-condensed and condensed in the air and condenser 320 in the air, the heat is discarded in the air, but in the present invention is sent to the lower portion of the heat storage tank 200 is exchanged with water of low temperature to be discarded first The heat is recovered and heat-exchanged in the heat exchanger 210b below the heat storage tank 200, and then the liquid refrigerant is sent to the condenser 320.

상기 응축기(320)는 실외공기와 열교환시켜 기체상태의 냉매를 액체상태로 응축하며, 팽창밸브(330)는 상기 응축기(320)를 통과한 액체냉매를 교축작용에 의해 저온저압의 액체냉매로 감압시킨다.The condenser 320 exchanges heat with outdoor air to condense a refrigerant in a gaseous state into a liquid state, and the expansion valve 330 decompresses the liquid refrigerant passing through the condenser 320 into a low-temperature low-pressure liquid refrigerant by throttling action. Let's do it.

상기 팽창밸브(330)를 통과하면서 저온저압으로 감압된 냉매는 상기 공기조화기(400)의 냉각코일(440)에 공급되어 여과된 공기와 열교환된 후, 다시 냉매순환배관(350)을 통해 압축기(310)에 공급되어 순환된다.The refrigerant, which has been reduced at low temperature and low pressure while passing through the expansion valve 330, is supplied to the cooling coil 440 of the air conditioner 400 and heat-exchanged with the filtered air, and then, again, the refrigerant is circulated through the refrigerant circulation pipe 350. It is supplied to circulated 310.

상기 압축기(310)를 중심으로 냉각코일(440)과 축열조(200) 사이의 냉매순환배관(350) 경로상에 각각 액분리기(360)와 유분리기(340)를 각각 설치하여, 액분리기(360)는 압축기(310)에 흡입되는 기체 중의 냉매액을 분리하여 액압축을 방지하고, 유분리기(340)는 압축기(310)에서 토출된 냉매 가스에 혼합되어 순환하는 냉동유를 회수하여 압축기를 보호할 수 있도록 한다.The liquid separator 360 and the oil separator 340 are respectively installed on the path of the refrigerant circulation pipe 350 between the cooling coil 440 and the heat storage tank 200 with respect to the compressor 310, respectively, and the liquid separator 360. ) Separates the refrigerant liquid in the gas sucked into the compressor 310 to prevent liquid compression, and the oil separator 340 protects the compressor by recovering refrigerated oil mixed with the refrigerant gas discharged from the compressor 310 and circulating. Do it.

즉, 상기 압축기(310)를 통과한 오일과 냉매는 배관을 통해 유분리기(340) 및 축열조(200)로 이송되는데, 이때 상기 오일은 유분리기(340)의 내부 밸브작동에 의해 다시 압축기(310)로 돌아가고 순수 냉매는 응축기(320)로 이동한다.That is, the oil and refrigerant passing through the compressor 310 are transferred to the oil separator 340 and the heat storage tank 200 through a pipe, wherein the oil is again compressed by the internal valve of the oil separator 340. And the pure refrigerant moves to the condenser 320.

또한 상기 냉각코일(440)을 통과하며 열교환되어 액상에서 기상으로 상변화 과정 중 증발이 안 된 액체냉매는 액분리기(360)로 유입되며, 상기 액분리기(360)는 압축기(310) 보호를 위하여 액체상태의 냉매가 유입되는 것을 방지한다.In addition, the liquid refrigerant that is not evaporated during the phase change process from the liquid phase to the heat exchanged through the cooling coil 440 is introduced into the liquid separator 360, the liquid separator 360 to protect the compressor 310 Prevents the introduction of liquid refrigerant.

여기에서, 상기 응축기(320)로부터 연장되어서 팽창밸브(330)측으로 향하는 냉매순환배관(350)의 경로상에 필터 드라이어(370)를 설치하여서, 상기 응축기(320)로부터 이송되는 냉매에 포함된 수분을 건조시켜 팽창밸브의 교축작용 부분에 수분이 결빙되는 것을 예방한다.

이와 같은 본 발명의 일 실시예에 따른 공조시스템의 작용을 살펴보면 다음과 같다.Looking at the operation of the air conditioning system according to an embodiment of the present invention as follows.

먼저 전기의 공급에 의해 공기조화기(400)와 냉동장치(300)가 구동되는 한편, 집열장치(100)는 태양추적센서(166)와 수평 회전부(162) 및 경사각 조절부(164)가 서로 연계하여 태양의 이동 궤적을 추적하면서 집열관(110)에서 태양빛을 집광하여 열매체유를 고온으로 가열하고, 태양광모듈(130)에서 태양광을 이용해 전압을 발생하여 집열장치(100)의 자체 동력으로 사용한다.First, the air conditioner 400 and the refrigerating device 300 are driven by the supply of electricity, while the heat collecting device 100 includes the solar tracking sensor 166, the horizontal rotating part 162, and the inclination angle adjusting part 164. Concentrates the sunlight in the heat collecting pipe 110 while tracking the movement trajectory of the sun by heating the heat medium oil at a high temperature, and generates a voltage using the sunlight from the solar module 130 to collect the heat of the heat collecting device 100 itself. Use it as a power source.

상기 고온으로 가열된 열매체유는 열매체유배관(150)을 통해 축열조(200) 중간의 열교환기(210a)에 공급되어 열교환에 의해 저장된 물을 온수로 만든다.The heat medium oil heated to the high temperature is supplied to the heat exchanger 210a in the middle of the heat storage tank 200 through the heat medium oil pipe 150 to make water stored by heat exchange into hot water.

한편, 상기 냉동장치(300)는 압축기(310)의 압축, 응축기(320)의 응축, 팽창밸브(330)의 팽창, 공기조화기(400)를 구성하는 냉각코일(440)의 증발 과정을 반복하면서 냉매가 순환하고, 공기조화기(400)의 케이스(410)에 공급된 공기는 믹스실(420)의 혼합, 공기여과기(430)의 여과, 냉각코일(440)의 냉각 및 제습, 가열코일(450)의 가열, 가습기(460)의 가습 과정을 거쳐 실내로 유입된다.Meanwhile, the refrigerating device 300 repeats the compression of the compressor 310, the condensation of the condenser 320, the expansion of the expansion valve 330, and the evaporation of the cooling coil 440 constituting the air conditioner 400. While the refrigerant circulates, the air supplied to the case 410 of the air conditioner 400 is mixed in the mix chamber 420, filtration of the air filter 430, cooling and dehumidifying the cooling coil 440, and heating coil.
