화석 연료의 유해성과 매장량의 한계로 인하여 근래에는 이를 대신할 수 있는 대체에너지 개발이 활발하게 진행되고 있다.Due to the harmfulness of fossil fuels and the limitations of reserves, in recent years, alternative energy development that can replace them has been actively pursued.

대표적으로 풍력, 태양열, 지열 등과 같은 자연에너지에 관한 연구가 진행되고 있는데, 이들 자연에너지는 환경오염과 기후변화에 거의 영향을 미치지 않으면서 무한한 에너지를 얻을 수 있는 장점이 있다.Representatively, research on natural energy such as wind power, solar heat, geothermal heat, etc. is being conducted. These natural energies have the advantage of obtaining infinite energy while having little effect on environmental pollution and climate change.

이러한 자연에너지 중 각광받고 있는 것이 지열을 이용하여 냉난방을 행하는 장치가 알려져 있는데, 이것은 지중의 열을 회수하거나 배출할 수 있도록 지중열교환기를 설치하여 냉난방을 행하는 기술이다. 지중의 온도는 계절의 변화에도 거의 일정하게 유지되므로 지열을 이용한 열교환장치는 여름에는 냉방장치로 겨울에는 난방장치로 사용할수 있다. 특히, 이런한 지열을 이용한 냉난방장치는 격오지 등에 설치시 매우 유용하게 사용될 수 있다.Among these natural energies, a device for cooling and heating using geothermal heat is known, which is a technology for cooling and heating by installing a ground heat exchanger to recover or discharge heat from the ground. Since the temperature of the ground is maintained almost constant even with the change of seasons, the heat exchanger using geothermal heat can be used as a cooling device in summer and a heating device in winter. In particular, such a cooling and heating device using geothermal heat can be very useful when installed in remote places.

그러나 이러한 종래의 지열을 이용한 냉난방장치는 냉방과 난방의 싸이클 중 어느 한 쪽을 집중적으로 사용할 경우, 상반되는 싸이클에서 효과적으로 열교환이 이루어지지 못하는 경우가 발생하는 문제가 있었다.However, such a conventional cooling and heating apparatus using geothermal heat has a problem in that when one of the cycles of cooling and heating is used intensively, heat exchange cannot be effectively performed in the opposite cycle.

Referring to FIG. 1, the heat pump 30 is a conventional heat pump 30. The refrigerant compressed to a high temperature and high pressure in the compressor 33 is sent to the condenser 31 to transfer heat to the heating tube 130 . The condenser 31 releases hot heat to the heating tube 130 and the low-temperature and low-pressure refrigerant phase-changed into a liquid refrigerant transfers cold heat from the evaporator 32 to the cooling tube 230 . In addition, an expansion valve and a 4-way valve are further configured, and a detailed description of the heat pump 30 will be omitted.

상기 난방기(110)는 공조공간(S)에 난방열을 발산하는 장치이다. 상기 축열조(120)로부터 인출되는 난방공급관(121)은 축열조(120)의 난방열인 온수를 난방기(110)로 공급한다. 공조공간(S)에서 난방열을 발산하여 일정온도를 상실한 온수는 상기 난방공급관(121)과 연결되는 난방회수관(122)을 통해 축열조(120)로 이송된다. The heater 110 is a device for dissipating heating heat in the air conditioning space (S). The heating supply pipe 121 drawn out from the heat storage tank 120 supplies hot water, which is heating heat of the heat storage tank 120, to the heater 110. Hot water that has lost a certain temperature due to heating heat emitted in the air conditioning space (S) is transported to the heat storage tank 120 through the heating recovery pipe 122 connected to the heating supply pipe 121 .

따라서, 상기 난방공급관(121)과 상기 난방회수관(122)은 상기 난방기(110)와 상기 축열조(120)를 연결하는 순환회로가 된다. 여기서, 바람직하게 난방공급관(121)에는 축열조(120)의 난방열을 난방기(110)로 강제 이송시키는 난방순환펌프(123)가 설치된다. 또한, 상기 난방순환펌프(123)가 설치되는 난방공급관(121)은 축열조(120)의 상부에 설치되고, 난방회수관(122)은 축열조(120)의 하부에 설치됨이 바람직하다. Therefore, the heating supply pipe 121 and the heating recovery pipe 122 become a circulation circuit connecting the heater 110 and the heat storage tank 120 . Here, a heating circulation pump 123 for forcibly transferring heating heat from the heat storage tank 120 to the heater 110 is preferably installed in the heating supply pipe 121 . In addition, it is preferable that the heating supply pipe 121 in which the heating circulation pump 123 is installed is installed above the heat storage tank 120, and the heating recovery pipe 122 is installed below the heat storage tank 120.

상기 축열조(120)는 상기 히트펌프(30)의 응축기(31)에서 냉매와의 열교환을 통해 생산된 온열을 이용하여 온도가 높아진 온수를 저장하는 곳이다. 이러한 축열조(120)는 온열관(130)을 통해 상기 히트펌프(30)의 응축기(31)와 순환연결된다. 그리고 난방운전시 공조공간(S)으로 온수를 공급한 후 회수할 수 있도록 상술한 난방공급관(121)과 난방회수관(122)을 통해 난방기(110)와도 순환연결된다.The heat storage tank 120 stores hot water whose temperature has increased by using hot heat generated through heat exchange with a refrigerant in the condenser 31 of the heat pump 30 . The heat storage tank 120 is circulated and connected to the condenser 31 of the heat pump 30 through the heat pipe 130 . In addition, it is circulated and connected to the heater 110 through the heating supply pipe 121 and the heating recovery pipe 122 so that hot water can be supplied to the air conditioning space S during heating operation and then recovered.

또한, 상기 온열관(130)은 상기 응축기(31)와 상기 축열조(120)를 순환연결함에 있어, 축열조(120)의 하부에는 온열유입관(131)이 연결되고, 축열조(120)의 상부에는 온열유출관(133)이 연결된다. 이때, 온열유입관(131)과 온열유출관(133)에는 차단밸브(132,134)가 설치된다. 그리고 바람직하게 상기 운열유입관에는 온열순환펌프(135)가 설치된다. In addition, when the thermal pipe 130 circulates and connects the condenser 31 and the heat storage tank 120, the heat inlet pipe 131 is connected to the lower part of the heat storage tank 120, and the upper part of the heat storage tank 120 The heat outlet pipe 133 is connected. At this time, shut-off valves 132 and 134 are installed in the warm heat inlet pipe 131 and the warm heat outlet pipe 133. And preferably, a thermal circulation pump 135 is installed in the cloud heat inlet pipe.

또한, 상기 온열관(130)에는 지중에서 열교환하는 제1지중열교환기(140)가 설치된다. 즉, 상기 제1지중열교환기(140)의 일단은 상기 온열유입관(131)에 연결되고, 타단은 상기 온열유출관(133)에 연결된다. 여기서, 상기 제1지중열교환기(140)의 각 단부에는 전환밸브(141,142)가 설치된다.In addition, the first underground heat exchanger 140 for exchanging heat in the ground is installed in the heating pipe 130. That is, one end of the first ground heat exchanger 140 is connected to the warm heat inlet pipe 131 and the other end is connected to the warm heat outlet pipe 133 . Here, switching valves 141 and 142 are installed at each end of the first underground heat exchanger 140.

본 발명에서 상기 제1지중열교환기(140)는 지중에서의 열방출을 목적으로 하며, 선택적 운영이 가능하다. In the present invention, the first underground heat exchanger 140 is aimed at dissipating heat from the ground, and selective operation is possible.

예컨데, 본 발명의 난방구성을 나타내느느 도 2처럼, 급탕 또는 공조공간(S)의 급속난방이 필요한 경우 제1지중열교환기(140)의 전환밸브(141,142)는 폐쇄하고, 상기 차단밸브(132,134)는 개방하여 운전한다. 그러면, 상기 온열순환펌프(135)의 동작에 따라, 상기 축열조(120) 상부의 온수가 상기 온열유출관(133)을 통해 상기 히프펌프 측으로 유입되어 응축기(31)에서 열교환을 통해 온열을 흡수한 후, 상기 온열유입관(131)을 통해 축열조(120)의 하부로 유입된다. 이렇게 상대적으로 온도가 높은 온수가 온열유입관(131)을 통해 축열조(120)의 하부로 지속유입됨에 따라, 상기 축열조(120)의 온수는 대류하여 온수 전체의 온도는 급속하게 상승하게 된다. 온도가 급속 상승한 온수는 상기 난방순환펌프(123)의 동작으로 축열조(120)의 하부에 연결된 상기 난방공급관(121)을 통해 공조공간(S)을 급속난방하거나, 급탕을 제공하게 된다. 이때, 상기 응축기(31)의 열원을 제공하는 증발기(32)에는 후술할 상기 축냉조(220) 및 상기 제2지중열교환기(240)를 연결하는 상기 냉열관(230)이 연결된다.For example, as shown in FIG. 2 showing the heating configuration of the present invention, when rapid heating of hot water or air conditioning space (S) is required, the switching valves 141 and 142 of the first ground heat exchanger 140 are closed, and the shutoff valves 132 and 134 ) is driven open. Then, according to the operation of the heat circulation pump 135, the hot water from the top of the heat storage tank 120 flows into the side of the hip pump through the heat outlet pipe 133 and absorbs heat through heat exchange in the condenser 31. After that, the heat flows into the lower portion of the heat storage tank 120 through the heat inlet pipe 131 . As the relatively high-temperature hot water continuously flows into the lower part of the heat storage tank 120 through the heat inlet pipe 131, the hot water in the heat storage tank 120 is convected and the temperature of the entire hot water rapidly rises. The hot water whose temperature has rapidly risen rapidly heats the air conditioning space (S) or provides hot water through the heating supply pipe 121 connected to the lower part of the heat storage tank 120 by the operation of the heating circulation pump 123. At this time, the cold storage pipe 230 connecting the cooling storage tank 220 and the second ground heat exchanger 240, which will be described later, is connected to the evaporator 32 providing the heat source of the condenser 31.

상기와 같은 급탕 또는 급속난방을 위한 운전은 상기 축열조(120)의 온수를 급격하게 상승시켜 난방시스템에 부하를 높이게 된다. 그러나 이러한 난방시스템의 과부하는 상기 제1지중열교환기(140)를 통해 빠르게 해소된다. 이는 도 2의 A방향으로의 운전을 개방하는 것으로, 상기 차단밸브(132,134)의 개방을 유지한 상태에서 상기 전환밸브(141,142)도 개방하는 것이다. 이렇게 하면, 온열순환펌프(135)의 동작에 의해 축열조(120) 상부의 온수가 온열유출관(133)을 거쳐 응축기(31)에서 온열을 흡수하여 온열유입관(131)으로 일부가 순환한다. 하지만 나머지 일부는 온열유입관(131)에 일단이 연결되는 제1지중열교환기(140)를 통해 지중에서 열방출 후 제1지중열교환기(140)의 타단이 연결되는 온열유출관(133)으로 회수된다. 이렇게 되면, 축열조(120)의 온수에는 제1지중열교환기(140)를 통해 열방출 후 상대적으로 낮은 온도의 온수가 지속적으로 섞이면서 축열조(120)의 전체 온수온도는 하강하게 된다. 다른 한편으로는, 차단밸브(132,134) 중 온열유입관(131)의 차단밸브(132)만을 간헐적으로 폐쇄하는 방법이 있다. 이 방법은 온열유출관(133)을 거쳐 응축기(31)에서 온열을 흡수한 온수의 전량이 제1지중열교환기(140)의 일단을 통해 지중에서 열방출 후 일정온도를 잃고 온열유출관(133)으로 회수되는 것으로, 이러한 과정을 수회 걸친 온수는 급격하게 온도를 잃게 되는데, 급격하게 온도를 잃은 온수를 온열유입관(131)의 차단밸브(132)를 개방하여 축열조(120)로 공급하면, 축열조(120)의 온수 온도를 보다 빠르게 낮출 수 있다.The above operation for hot water supply or rapid heating increases the load on the heating system by rapidly increasing the hot water in the heat storage tank 120 . However, the overload of the heating system is quickly resolved through the first ground heat exchanger 140. This is to open the operation in the direction A of FIG. 2, and to open the switching valves 141 and 142 while keeping the shut-off valves 132 and 134 open. In this way, by the operation of the heat circulation pump 135, hot water from the upper portion of the heat storage tank 120 passes through the heat outlet pipe 133 to absorb heat from the condenser 31 and partially circulates through the heat inlet pipe 131. However, some of the remaining heat is discharged from the ground through the first underground heat exchanger 140, one end of which is connected to the warm heat inlet pipe 131, and then transferred to the heated heat outlet pipe 133 to which the other end of the first ground heat exchanger 140 is connected. is recovered In this case, the hot water of the heat storage tank 120 is continuously mixed with hot water of a relatively low temperature after heat is discharged through the first ground heat exchanger 140, and the overall temperature of the hot water of the heat storage tank 120 is lowered. On the other hand, there is a method of intermittently closing only the shutoff valve 132 of the warm heat inlet pipe 131 among the shutoff valves 132 and 134. In this method, the entire amount of the hot water absorbed by the condenser 31 through the hot heat outlet pipe 133 is discharged from the ground through one end of the first underground heat exchanger 140, and then loses a certain temperature and the thermal heat outlet pipe 133 ), and the hot water that has undergone this process several times rapidly loses its temperature. When the hot water that has rapidly lost its temperature is supplied to the heat storage tank 120 by opening the shut-off valve 132 of the heat inlet pipe 131, The hot water temperature of the heat storage tank 120 can be lowered more quickly.

상기 냉방기(210)는 공조공간(S)에 냉방열을 발산하는 장치이다. 상기 축냉조(220)로부터 인출되는 냉방공급관(221)은 축냉조(220)의 냉방열인 냉수를 냉방기(210)로 공급한다. 공조공간(S)에서 냉방열을 발산하여 일정온도를 상실한 온수는 상기 냉방공급관(221)과 연결되는 냉방회수관(222)을 통해 축냉조(220)로 이송된다.The air conditioner 210 is a device that dissipates cooling heat in the air conditioning space (S). The cooling supply pipe 221 drawn out from the cooling storage tank 220 supplies cold water, which is the cooling heat of the cooling storage tank 220, to the cooler 210. Hot water that has lost a certain temperature due to cooling heat dissipation in the air conditioning space (S) is transported to the cooling storage tank 220 through the cooling recovery pipe 222 connected to the cooling supply pipe 221.

따라서, 상기 냉방공급관(221)과 상기 냉방회수관(222)은 상기 냉방기(210)와 상기 축냉조(220)를 연결하는 순환회로가 된다. 여기서 바람직하게 냉방공급관(221)에는 축냉조(220)의 냉방열을 냉방기(210)로 강제 이송시키는 냉방순환펌프(223)가 설치된다. 또한, 상기 냉방순환펌프(223)가 설치되는 냉방공급관(221)은 축냉조(220)의 하부에 설치되고, 냉방회수관(222)은 축냉조(220)의 상부에 설치됨이 바람직하다.Therefore, the cooling supply pipe 221 and the cooling return pipe 222 become a circulation circuit connecting the air conditioner 210 and the cold storage tank 220 . Preferably, a cooling circulation pump 223 is installed in the cooling supply pipe 221 to forcibly transfer cooling heat from the cooling storage tank 220 to the cooler 210. In addition, it is preferable that the cooling supply pipe 221 in which the cooling circulation pump 223 is installed is installed below the cooling storage tank 220, and the cooling return pipe 222 is installed above the cooling storage tank 220.

상기 축냉조(220)는 상기 히트펌프(30)의 증발기(32)에서 냉매와의 열교환을 통해 생산된 냉열을 이용하여 온도가 낮아진 냉수를 저장하는 곳이다. 이러한 축냉조(220)는 냉열관(230)을 통해 상기 히트펌프(30)의 증발기(32)와 순환연결된다. 그리고 도 3에서 처럼, 냉방운전시 공조공간(S)으로 냉수를 공급한 후, 회수될 수 있도록 상술한 냉방공급관(221)과 냉방회수관(222)을 통해 냉방기(210)와도 순환연결된다.The cooling tank 220 stores cold water whose temperature is lowered by using cold heat produced through heat exchange with a refrigerant in the evaporator 32 of the heat pump 30 . The cold storage tank 220 is circulated and connected to the evaporator 32 of the heat pump 30 through the cold-heat pipe 230 . And, as shown in FIG. 3, after supplying cold water to the air conditioning space (S) during cooling operation, it is circulated and connected to the air conditioner 210 through the above-described cooling supply pipe 221 and the cooling recovery pipe 222 so that it can be recovered.

상기 냉열관(230)은 상기 증발기(32)와 상기 축냉조(220)를 순환연결함에 있어, 축냉조(220)의 하부에는 냉열 제1순환펌프(231)가 설치된 냉열관(230)의 타단이 연결되며, 냉열관(230)의 일단에는 상기 제2지중열교환기(240)의 타단이 연결된다. 이때, 상기 제2지중열교환기(240)의 일단은 냉열 제2순환펌프(241)를 구비하여 상기 축냉조(220)의 상부에 연결된다.The cold-heat pipe 230 circulates the evaporator 32 and the cold storage tank 220, and the other end of the cold-heat pipe 230 has a first cold-heat circulation pump 231 installed at the bottom of the cold storage tank 220. This is connected, and the other end of the second underground heat exchanger 240 is connected to one end of the cold heat pipe 230. At this time, one end of the second underground heat exchanger 240 is provided with a second cold heat circulation pump 241 and is connected to the upper part of the cooling storage tank 220 .

이러한 구성을 통해, 상기 냉열제2순환펌프의 동작으로 상기 제2지중열교환기(240)가 상기 축냉조(220) 상부의 냉수를 강제 이송시켜 지중에서 열기를 흡수한다. 이렇게 흡수된 열기는 상기 히트펌프(30)의 증발기(32)에서 응축기(31)를 거쳐, 상기 온열관(130)으로 이전된다. 그리고 증발기(32)에서 일정 열기를 상실하고 냉열상태가 된 냉수는 상기 냉열제1순환펌프의 동작을 통해 상기 냉열관(230)을 타고 축냉조(220)의 하부로 유입된다. 여기서 상기 제2지중열교환기(240)는 지중에서의 열흡수를 목적으로 한다. 그런데 상술한 바와 같이 상기 제1지중열교환기(140)는 지중에서 열방출을 목적으로 하고 있다. 그러므로, 본 발명에서는 제1지중열교환기(140)의 열방출과 제2지중열교환기(240)의 열흡수가 효과적으로 수행될 수 있도록, 바람직하게 제2지중열교환기(240)의 배관라인을 따라서 상기 제1지중열교환기(140)의 배관라인을 구성한다. 이에 따라 제1지중열교환기(140)에서 방출된 열을 제2지중열교환기(240)에서 흡수하여 히트펌프(30)로 전달함으로써, 히트펌프(30)의 효율이 증대될 수 있는 것이다.Through this configuration, the second underground heat exchanger 240 forcibly transports the cold water above the cooling storage tank 220 by the operation of the second cold heat circulation pump to absorb heat in the ground. The absorbed heat is transferred from the evaporator 32 of the heat pump 30 through the condenser 31 to the thermal tube 130 . In addition, the cold water that has lost a certain amount of heat from the evaporator 32 and is in a cold heat state flows into the lower part of the cold storage tank 220 through the cold heat pipe 230 through the operation of the first cold heat circulation pump. Here, the second underground heat exchanger 240 aims to absorb heat from the ground. However, as described above, the first underground heat exchanger 140 aims to release heat from the ground.

Constituting the piping line of the first underground heat exchanger (140). Accordingly, the heat emitted from the first underground heat exchanger 140 is absorbed by the second underground heat exchanger 240 and transferred to the heat pump 30, thereby increasing the efficiency of the heat pump 30.
