본 발명은 냉·난방 효율이 향상된 복합형 히트펌프 사이클에 관한 것으로, 보다 상세하게는 냉방, 난방, 온수를 개별 혹은 선택적으로 동시 사용하도록 하는 냉·난방 효율이 향상된 복합형 히트펌프 사이클에 관한 것이다.The present invention relates to a hybrid heat pump cycle with improved cooling and heating efficiency, and more particularly to a hybrid heat pump cycle with improved cooling and heating efficiency allowing individual or selective simultaneous use of cooling, heating and hot water. .

종래에 히트펌프 사이클은 냉방운전시 압축기를 통해 냉매가 고온고압으로 변화되고, 사방밸브를 거쳐 고온고압의 냉매는 실외측 열교환기를 통과하여 외부공기와 열교환되어 저온고압으로 변화된다. 이어서 저온고압의 냉매는 팽창밸브를 통과하며 저온저압으로 변화되어 실내측 열교환기에서 열교환되어 실내공기를 냉방하고 압축기로 이송되어 상기와 같은 사이클을 반복하게 된다.In the conventional heat pump cycle, the refrigerant is changed to high temperature and high pressure through a compressor during the cooling operation, and the refrigerant having high temperature and high pressure passes through an outdoor side heat exchanger through a four-way valve to exchange heat with external air to change to low temperature and high pressure. Subsequently, the low temperature and high pressure refrigerant passes through the expansion valve and is changed to low temperature and low pressure to be heat exchanged in the indoor heat exchanger to cool the indoor air and transfer to the compressor to repeat the above cycle.

그리고, 난방운전시에는 압축기를 통과한 냉매가 사방밸브의 조작에 의해 실내측 열교환기로 공급되어 실내를 난방하고, 실내측 열교환기를 통과한 냉매는 냉방운전시의 흐름과 역순으로 팽창밸브, 실외측 열교환기를 거쳐 순환된다. 또 사방밸브를 통하여 연결되는 압축기와 실내측 열교환기 사이에 난방용 열교환기를 추가로 설치하여 고온고압의 냉매를 온수로 열교환하는 온수겸용 히트펌프 사이클이 개발되고 있다.In the heating operation, the refrigerant passing through the compressor is supplied to the indoor heat exchanger by operating the four-way valve to heat the interior, and the refrigerant passing through the indoor heat exchanger flows in the inverse order of the expansion valve and the outdoor side in the reverse order of the cooling operation. Circulated through a heat exchanger. In addition, a hot water heat pump cycle for installing a heat exchanger for heating between the compressor connected to the four-way valve and the indoor side heat exchanger is further developed to heat the high temperature and high pressure refrigerant with hot water.

즉, 상기한 온수겸용 히트펌프 사이클은 사방밸브가 압축기와 직설되어 히트펌프에서 고온고압으로 변화된 냉매가 냉난방시 난방용 열교환기 및 실외측 열교환 기, 실내측 열교환기를 선택적으로 통하여 실내를 냉난방하며 온수를 가열한다.That is, in the above-mentioned hot water combined heat pump cycle, the four-way valve is directly connected to the compressor, and when the refrigerant changed from the heat pump to the high temperature and high pressure is cooled and heated, the indoor heat exchanger is selectively heated and heated to provide hot water. Heat.

하지만, 냉방시 난방용 열교환기에 저장된 온수가 일정온도이상 가열되면 고온고압상태의 냉매가 저온고압 상태로 열교환이 이루어지지 못하여 실내측 열교환기를 통한 실내냉방효율이 저하된다. 이에 난방용 열교환기의 온수 온도가 일정온도이상 가열되면 냉매의 흐름을 실외측 열교환기로 전환하여 냉매를 저온고압으로 열교환 후 실내측 열교환기로 공급하는 복잡한 구조를 가진다.However, when the hot water stored in the heat exchanger for heating is heated above a predetermined temperature, the refrigerant in the high temperature and high pressure state is not heat exchanged in the low temperature and high pressure state, and thus the indoor cooling efficiency through the indoor side heat exchanger is lowered. Therefore, when the hot water temperature of the heating heat exchanger is heated above a predetermined temperature, the flow of the refrigerant is switched to the outdoor heat exchanger and has a complicated structure in which the refrigerant is heat-exchanged at low temperature and high pressure and then supplied to the indoor heat exchanger.

또한, 난방시에도 압축기에서 고온고압으로 변화된 냉매가 난방용 열교환기를 1차적으로 거쳐 저온고압으로 변화되어 실내측 열교환기로 공급되므로 난방용 열교환기에 온수가 일정온도까지 가열되기 전까지는 실내 난방을 기대하기 어렵고, 도리어 초기에는 냉풍이 발생되는 폐단이 따랐다.In addition, since the refrigerant changed from the compressor to the high temperature and high pressure changes to the low temperature and high pressure primarily through the heat exchanger for heating, it is difficult to expect room heating until the hot water is heated to a predetermined temperature in the heat exchanger. Rather, early stages were followed by a cold wind.

이에 따라 본 발명은 상기한 점에 착안하여 안출한 것으로서, 보다 상세하게는 난방용 열교환기의 성능이 향상되도록 히트펌프 사이클라인을 개선하고, 실외기온에 영향을 받지 않고 실외측 열교환기를 통한 냉매의 열교환 성능을 향상시키기 위한 냉·난방 효율이 향상된 복합형 히트펌프 사이클을 제공하는 것을 그 목적으로 한다.Accordingly, the present invention has been made in view of the above points, and more particularly, the heat pump cycle line is improved to improve the performance of the heat exchanger for heating, and the heat exchange of the refrigerant through the outdoor heat exchanger is not affected by the outdoor temperature.

그리고, 버퍼탱크(12)에 저장되는 난방수는 난방수배관(12a)을 타고 실내바닥은 물론 후술하는 실내측 열교환기(34)의 물순환식방열판(60)으로 공급되어 온풍난방을 하는바, 이에 따른 상세한 설명은 후술하는 내용을 참조한다.In addition, the heating water stored in the buffer tank 12 is supplied to the water circulation type heat sink 60 of the indoor side heat exchanger 34 as well as the indoor floor through the heating water pipe 12a to perform warm air heating. For details, refer to the following description.

이에 상기한 바와 같이 압축기(C)에서 고온고압상태로 변화된 냉매가 난방용 열교환기(10)를 거쳐 버퍼탱크(12)에 저장된 난방수 및 온수를 가열한 다음, 사방밸브(20)를 통하여 냉방 혹은 난방라인으로 선택적으로 이송되므로 난방용 열교환기(10)의 열교환효율이 항상 일정하게 유지되는바, 특히 냉방시 난방용 열교환기(10)를 거쳐 중·저온고압 상태로 변화된 냉매가 실외측 열교환기(50)에서 재응축되어 실내측 열교환기(34)로 공급되므로 냉방효율이 향상되는 이점이 있다. Thus, as described above, the refrigerant changed to the high temperature and high pressure state in the compressor C heats the heating water and hot water stored in the buffer tank 12 through the heat exchanger 10 for heating, and then cools or cools through the four-way valve 20. Since the heat exchange efficiency of the heat exchanger 10 for heating is always kept constant since it is selectively transferred to the heating line, the coolant changed to a medium, low temperature, high pressure state through the heating heat exchanger 10 during cooling, and the outdoor heat exchanger 50 Recondensed in the) is supplied to the indoor heat exchanger 34 has the advantage of improving the cooling efficiency.

또한, 상기 실외측 열교환기(50)는 팬(52) 혹은 지중에 매립된 지열관(54)과 순환펌프(56)를 통하여 순환되는 수냉매에 의해 열교환이 이루어진다. 실외측 열교 환기(50)는 도 1 내지 도 3과 같이 지열관(54)에 수용된 수냉매가 순환펌프(56)에 의해 순환되며 냉매와 열교환이 이루어지거나 도 5처럼 팬(52)의 작동에 의해 냉매가 방열판을 이송되는 중에 열교환된다.In addition, the outdoor heat exchanger 50 is heat-exchanged by the fan 52 or the water refrigerant circulated through the geothermal tube 54 and the circulation pump 56 embedded in the ground. The outdoor heat exchanger 50 is a water refrigerant contained in the geothermal tube 54 as shown in Figures 1 to 3 is circulated by the circulation pump 56 and the heat exchange with the refrigerant is made or the operation of the fan 52 as shown in FIG. As a result, the refrigerant is heat-exchanged while transferring the heat sink.

이때, 지열을 이용한 열교환 방식은 계절 기후에 따라 변화되는 실외기온에 영향을 받지 않고 일정한 온도로 유지되는 지열(예컨대, 약 13도정도)에 의해 난방시 실외측 열교환기(50)를 통하는 냉매를 고온저압상태로 변화시키거나 냉방시 냉매를 재응축하여 응축효율이 향상되므로 냉·난방 효율이 향상되는 이점이 있다.In this case, the heat exchange method using geothermal heat is used to cool the refrigerant through the outdoor heat exchanger 50 when heated by geothermal heat (for example, about 13 degrees) that is maintained at a constant temperature without being affected by the outdoor temperature that changes according to the seasonal climate. The condensation efficiency is improved by changing to a high temperature low pressure state or re-condensing the refrigerant during cooling, thereby improving the cooling and heating efficiency.

또한, 상기 실내측 열교환기(34)의 냉방방열판(34a)과 인접한 위치에 물순환식방열판(60)이 구비되고, 물순환식방열판(60)은 삼방변(62)에 의해 난방수배관(12a) 혹은 지열관(54)과 선택적으로 연결된다. 물순환식방열판(60)은 도 4처럼 실내측 열교환기(34)상에 냉방방열판(34a)과 이격된 위치에 설치되어 난방시 도 2와 같이 삼방변(62)이 난방수배관(12a)의 난방수를 공급하여 실내를 온풍난방하고, 냉방시 삼방변(62)의 작동으로 도 3에 도시된 바와 같이 지열관(54)의 수냉매가 순환되어 실내를 냉방하게 된다. 이에 조금 무더운 초여름 혹은 초가을에 히트펌프 사이클 즉, 냉·난방장치를 가동하지 않고서도 실내를 냉방하므로 에너지 절감효과가 크다. 여기서 삼방변(62)은 3방향으로 연결된 유로의 흐름방향을 전환하는 밸브이다.In addition, the water circulation plate 60 is provided at a position adjacent to the cooling radiating plate 34a of the indoor heat exchanger 34, the water circulation plate 60 is a three-way heating water pipe ( 12a) or optionally connected to geothermal tube 54. The water circulation plate 60 is installed at a position spaced apart from the cooling plate 34a on the indoor side heat exchanger 34 as shown in FIG. 4, and the three-way valve 62 is provided with a heating water pipe 12a as shown in FIG. By supplying the heating water of the room to heat the hot air, and the cooling operation of the three-way side 62, as shown in FIG. 3, the water refrigerant of the geothermal tube 54 is circulated to cool the room. This is a little hot summer or early autumn heat pump cycle, that is, cooling the room without operating the heating and cooling system, the energy saving effect is great. The three-way side 62 is a valve for switching the flow direction of the flow path connected in three directions.

한편, 상기한 난방용 열교환기(10) 및 사방변(20), 실내·외측 열교환기(34)(50), 지열관(54), 난방수배관(12a), 제1, 2팽창변(32)(42), 삼방변(62) 등은 제어부(도시생략)에 의해 개폐작동되는 다수의 밸브에 의해 냉·난방조건에 따 라 냉매, 수냉매, 난방수, 온수 등의 흐름이 제어된다.Meanwhile, the heating heat exchanger 10 and the four sides 20, the indoor and external heat exchangers 34 and 50, the geothermal tube 54, the heating water pipe 12a, and the first and second expansion sides 32. 42, the three-way side 62 and the like, the flow of the refrigerant, water refrigerant, heating water, hot water and the like are controlled by a plurality of valves that are opened and closed by a control unit (not shown).

이상의 구성 및 작용에 의하면, 본 발명은 냉·난방운전시 압축기에서 고온고압상태로 변화된 냉매가 난방용 열교환기를 거쳐 사방변으로 이동하므로 냉·난방 사이클에 관계없이 버퍼탱크의 축열효율이 향상되고, 또 실내측 열교환기상에 냉방방열판과 물순환식방열판이 복합적으로 구비되어 냉풍 혹은 온풍을 통한 냉·난방을 선택적으로 실시할 수 있는 효과가 있다.According to the above configuration and operation, in the present invention, since the refrigerant changed from the compressor to the high temperature and high pressure state during the cooling and heating operation moves to the four sides through the heat exchanger for heating, the heat storage efficiency of the buffer tank is improved regardless of the cooling and heating cycles. The cooling heat dissipation plate and the water circulating heat dissipation plate are combined on the indoor side heat exchanger, so that cooling and heating through cold or warm air can be selectively performed.

또한, 지열을 이용한 실외측 열교환기의 열교환방식으로 실외기온에 큰 영향을 받지 아니하고 냉매의 열교환 성능이 향상되는 효과가 있다.In addition, the heat exchange method of the outdoor heat exchanger using geothermal heat has an effect of improving the heat exchange performance of the refrigerant without being greatly affected by the outdoor temperature.

또한, 초여름 및 초가을에 냉·난방장치를 가동하지 아니하고도 지열만으로 실내냉방을 실시하므로 에너지를 크게 절감할 수 있는 효과가 있다.In addition, since indoor cooling is performed only by geothermal heat without operating a cooling / heating device in early summer and early autumn, energy can be greatly reduced.
