본 발명은 히트펌프를 이용한 냉동, 냉장 및 온수축열시스템에 관한 것으로, 더욱 상세하게는 히트펌프를 이용하여 냉동 또는 냉장이 필요한 장소를 냉각시키고, 이 과정에서 배출되는 폐열을 이용하여 생활용수를 가열함으로써, 에너지를 절감할 수 있는 히트펌프를 이용한 냉동, 냉장 및 온수축열시스템에 관한 것이다.The present invention relates to a refrigeration, refrigeration and hot water heat storage system using a heat pump, and more particularly to a place where refrigeration or refrigeration is required using a heat pump, and to heat living water using waste heat discharged in the process.

최근 석유수출기구(OPEC)의 지속적인 감산정책과 신흥공업국에 의한 에너지소비 증가 및 투기자금의 원유시장 유입 등으로 국제유가가 연일 사상최고치를 갱신하고 있으며, 화석연료의 과다한 사용으로 인한 이상기온현상이 증가함에 따라 에너지 절약시설에 대한 관심이 더욱 증대되고 있다.The recent oil price update by the OPEC, rising energy consumption by emerging industrial countries, and the inflow of speculative oil into the oil market have caused international oil prices to update to record highs daily. Increasingly, interest in energy-saving facilities is increasing.

한편, 오늘날에는 경제규모가 커짐에 따라 대형건물이나 대형시설들이 날이 갈수록 증가하고 있으며, 이러한 건물들은 실내온도 유지를 위하여 고용량의 냉난방 장치들을 구비하고 있으며, 대형 유통업체, 식품회사 등은 식품저장을 위해 냉동기를 사용하여 저온창고를 운영하고 있다.On the other hand, today, as the economy grows, large buildings and facilities are increasing day by day, and these buildings are equipped with high-capacity air-conditioning units to maintain indoor temperature.

The refrigerant is cooled while the refrigerant evaporates in the evaporator 24 to absorb the surrounding heat, and the heat absorbed through the evaporator 24 is compressed through the compressor 21 to form a gas of high temperature and high pressure. The high temperature and high pressure gas is cooled through the condenser 22, and the heat generated through the condenser 22 is discharged to the outside through the cooling tower 30.

한편, 도 2는 일반적인 난방장치의 구성을 보여주는 도면으로, 난방장치는 보일러(40) 및 온수저장탱크(50)로 구성되어 있으며, 온수저장탱크(50)에는 실내로 온수를 공급하는 온수공급관(51)과 실내에서 소비하고 남은 온수를 재가열하기 위하여 회수하는 온수회수관(52)이 연결되어 있다.On the other hand, Figure 2 is a view showing the configuration of a general heating device, the heating device is composed of a boiler 40 and hot water storage tank 50, the hot water storage tank 50 is a hot water supply pipe for supplying hot water to the room ( 51) is connected to the hot water recovery pipe 52 for recovering the hot water remaining in the room to reheat.

보일러(40)는 내부에 연소실(41)이 구비되어 있으며, 연소실(41) 내에 있는 버너나 히터 등과 같은 열원(43)으로부터 열을 공급받아서 열교환기(42)를 통하여 냉수를 온수로 가열한 후, 온수저장탱크(50)에 저장해 둔다. 온수저장탱크(50)에 저장된 온수는 온수공급관(51)을 통하여 온수를 필요로 하는 곳으로 공급되고, 실내에서 소비되고 남은 온수는 재가열을 위하여 온수회수관(52)을 통하여 회수된다.The boiler 40 is provided with a combustion chamber 41 therein, and receives the heat from a heat source 43 such as a burner or a heater in the combustion chamber 41 and heats cold water with hot water through the heat exchanger 42.

The hot water stored in the hot water storage tank 50 is supplied to a place requiring hot water through the hot water supply pipe 51, and the hot water remaining in the room is recovered through the hot water collection pipe 52 for reheating.

상기 냉방장치와 난방장치는 계절이나 기온의 변화에 따라 정도의 차이는 있지만 연중 동시에 사용되는 경우가 많다. 예를 들어, 병원이나 호텔의 경우 여름철 에 에어컨 가동, 혈액 또는 음식물 보관 등을 위하여 냉방장치를 많이 사용하지만, 환자나 고객을 위하여 실내난방 및 온수를 공급해야 하기 때문에 난방장치를 가동하는 경우도 많으며, 겨울철에도 난방장치를 많이 사용하지만, 음식물보관 등을 위하여 냉방장치도 함께 사용하는 경우가 많다.The cooling device and the heating device may be used at the same time throughout the year, although there is a difference in degree depending on the season or the change of temperature. For example, hospitals and hotels often use air conditioners to operate air conditioners, store blood or food in the summer, but often operate heating devices because they need to supply indoor heating and hot water for patients or customers. In winter, the heating system is used a lot, but the air conditioner is often used for food storage.

상기와 같은 일반적인 경우에, 종래의 냉난방장치는 냉방장치와 난방장치가 각각 별개로 설치되어 있기 때문에, 여름철에 실내온도를 낮추기 위하여 냉방장치를 가동하면서, 한편으로는 온수를 얻기 위하여 난방장치를 가동시켜야 하는 문제점이 있었다.In the general case as described above, since the air conditioner and the heating device are separately installed, the conventional air conditioner operates the air conditioner in order to lower the room temperature in summer, while operating the heating device to obtain hot water. There was a problem to be done.

또한, 호텔 또는 식품회사 등에서 음식물 등을 저장하기 위하여 냉동장치를 사용하고, 이때 발생하는 냉각수 폐열을 냉각탑을 통하여 연중 배출하여 상당한 에너지낭비가 되고 있다.In addition, a hotel or a food company uses a refrigeration apparatus for storing food and the like, and the waste heat generated at this time is discharged through the cooling tower throughout the year, which is a significant energy waste.

본 발명은 상기와 같은 종래기술에 따른 문제점을 해결하기 위한 것이다. 즉, 본 발명의 목적은 히트펌프를 이용하여 냉동 또는 냉장이 필요한 장소를 냉각시키고, 이 과정에서 배출되는 폐열을 이용하여 생활용수를 가열함으로써, 에너지를 절감할 수 있는 히트펌프를 이용한 냉동, 냉장 및 온수축열시스템을 제공하는데에 있다.The present invention is to solve the problems according to the prior art as described above. That is, an object of the present invention is to freeze or refrigerate using a heat pump that can save energy by cooling a place where refrigeration or refrigeration is required using a heat pump, and heating living water using waste heat discharged in this process. And to provide a hot water storage system.

상기의 목적을 달성하기 위하여 본 발명은, 냉기를 보관하는 냉동창고와; 상기 냉동창고와 냉각회로로 연결되어 있으며, 압축기, 응축기, 팽창밸브 및 증발기가 하나의 사이클을 구성하고, 상기 사이클을 냉매가 순환하면서 상기 냉동창고의 열을 흡수하여 상기 냉동창고 밖으로 내보내는 히트펌프와; 상기 히트펌프와 축열회로로 연결되어 있으며, 응축기로부터 발생하는 열을 흡수하여 온수를 생산하고, 생산된 온수를 저장하는 온수축열 탱크와; 상기 축열회로와 연결되어 있으며, 상기 히트펌프에서 발생하는 온수가 상기 온수축열 탱크에 저장이 완료되면 나머지 열을 외기로 방출하는 냉각탑; 및 상기 온수축열 탱크와 가열회로로 연결되어 있으며, 상기 온수축열 탱크에 저장되어 있는 온수를 이용하여 실내에서 사용할 온수를 가열하는 열교환기;로 이루어진 것을 특징으로 한다.In order to achieve the above object, the present invention provides a freezer for storing cold air; Is connected to the freezer and the cooling circuit, the compressor, condenser, expansion valve and the evaporator constitutes a cycle, the cycle of the refrigerant to absorb the heat of the freezer warehouse while the cycle circulates and out of the freezer warehouse and ; A hot water heat storage tank connected to the heat pump and a heat storage circuit, absorbing heat generated from a condenser to produce hot water, and storing the produced hot water; A cooling tower connected to the heat storage circuit and discharging the remaining heat to the outside when the hot water generated in the heat pump is completely stored in the hot water heat storage tank; And a heat exchanger connected to the hot water storage tank and a heating circuit and using the hot water stored in the hot water storage tank to heat hot water for use indoors.

본 발명에 의하면, 냉방과정에서 발생하는 폐열을 활용하여 온수를 가열함으 로써, 에너지를 절감할 수 있을 뿐만 아니라, 환경오염을 방지하는 효과가 있다. 또한, 냉방과정에서 응축기를 통하여 발생하는 열을 온수를 만드는 과정에서 효과적으로 식혀주고, 난방장치를 가동하지 않고도 온수를 가열할 수 있기 때문에 냉난방장치의 부하를 줄일 수 있고, 가동시간을 단축할 수 있으므로 운영비 및 수리비 등을 절감할 수 있는 효과가 있다. According to the present invention, by heating the hot water by utilizing the waste heat generated in the cooling process, not only can save energy, but also has an effect of preventing environmental pollution. In addition, since the heat generated by the condenser in the cooling process can be effectively cooled in the process of making hot water, and the hot water can be heated without operating the heating device, the load of the air conditioning system can be reduced and the operating time can be shortened. It is effective to reduce operating costs and repair costs.

이하, 본 발명의 바람직한 실시 예를 첨부도면에 의거하여 상세하게 설명하기로 한다. 다만, 본 발명은 그 요지를 이탈하지 않는 한 이하의 실시 예에 한정되지 않는다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the following embodiments unless departing from the gist of the present invention.

도 3은 본 발명의 제1 실시 예에 따른 히트펌프를 이용한 냉동, 냉장 및 온수축열시스템의 구성을 보여주는 도면이다.3 is a view showing the configuration of a refrigeration, refrigeration and hot water heat storage system using a heat pump according to a first embodiment of the present invention.

도 3을 참조하면, 본 발명의 제1 실시 예에 따른 히트펌프를 이용한 냉동, 냉장 및 온수축열시스템은 냉동창고(100), 히트펌프(200), 온수축열 탱크(300), 냉각탑(400) 및 열교환기(500)로 구성되어 있다.Referring to Figure 3, the refrigeration, refrigeration and hot water storage system using a heat pump according to the first embodiment of the present invention the freezer warehouse 100, heat pump 200, hot water storage tank 300, cooling tower 400 And a heat exchanger 500.

냉동창고(100)는 냉동 또는 냉장을 원하는 장소를 나타내는 것으로, 반드시 냉동 또는 냉장창고만을 의미하는 것이 아니라, 대형에어컨을 가동하는 건물의 경우에는 건물 전체가 냉동창고(100)와 같은 역할을 한다.The freezer 100 indicates a desired place for freezing or refrigeration, and does not necessarily mean only the freezing or cold storage, but in the case of a building operating a large air conditioner, the entire building serves as the freezing warehouse 100.

냉동창고(100)는 냉각회로(C1)를 통하여 히트펌프(200)의 증발기(240)와 접촉하도록 연결되어 있다. 상기 냉각회로(C1)는 냉동창고(100)를 냉각시키는 냉수를 이송하는 제1펌프(P1)와 냉수의 온도를 측정하는 온도센서(TE-01, TE-02)로 구성되어 있으며, 냉각회로(C1) 내를 흐르는 물은 히트펌프(200)의 증발기(240)와 열교환을 하면서 열을 빼앗기고, 다시 냉동창고(100)로 돌아가서 주변의 열을 흡수하면서 냉동창고(100)를 냉각시키는 과정을 계속적으로 반복한다.The freezer warehouse 100 is connected to contact the evaporator 240 of the heat pump 200 through the cooling circuit (C1). The cooling circuit (C1) is composed of a first pump (P1) for transferring cold water for cooling the freezer warehouse 100 and temperature sensors (TE-01, TE-02) for measuring the temperature of the cold water, the cooling circuit Water flowing through the (C1) is heat exchanged with the evaporator 240 of the heat pump 200 to take heat away, and return to the freezing warehouse 100 again to absorb the surrounding heat to cool the freezing warehouse (100) Repeat continuously.

히트펌프(200)는 압축기(210), 응축기(220), 팽창밸브(230) 및 증발기(240)로 구성되어 있으며, 내부에는 냉매가 들어 있다. 압축기(210)는 기체 상태인 냉매를 고온ㆍ고압의 기체로 압축하여 응축기(220)로 보내주고, 응축기(220)에서는 상기 압축기(210)에서 보내주는 압축된 냉매를 냉각하여 액화시키며, 상기 응축기(220)에서 액화된 냉매를 팽창밸브(230)를 통하여 팽창시키면서 증발기(240)로 분사시키면, 증발기(240)에서는 분사된 냉매가 급팽창하여 주위의 열, 즉 냉각회로(C1)로부터 열을 빼앗으면서 증발하게 된다. 상기 과정을 통하여 증발기(240)에서는 냉동기(100)를 냉각시키는데 필요한 냉수를 만들고, 응축기(220)에서는 방출되는 폐열을 이용하여 온수를 가열하게 되는데, 온수가열에 관하여는 후에 설명한다.The heat pump 200 is composed of a compressor 210, a condenser 220, an expansion valve 230 and the evaporator 240, the refrigerant is contained therein. The compressor 210 compresses a gaseous refrigerant into a gas of high temperature and high pressure, and sends the refrigerant to the condenser 220, and the condenser 220 cools and liquefies the compressed refrigerant sent from the compressor 210. When the refrigerant liquefied at 220 is injected into the evaporator 240 while expanding through the expansion valve 230, the injected refrigerant rapidly expands in the evaporator 240 to extract heat from the surrounding heat, that is, the cooling circuit C1. It takes away and evaporates. Through the above process, the evaporator 240 makes cold water required to cool the freezer 100, and the condenser 220 heats hot water by using the waste heat discharged. The hot water heating will be described later.

온수축열 탱크(300)는 응축기(220)에서 가열된 온수를 저장하는 곳으로, 물의 온도에 따른 밀도차를 이용하여 낮은 온도의 물과 높은 온도의 물을 상하로 분리하여 저장하는 디퓨저(diffuser)를 구비하도록 설계되어 있고, 내부에는 각각의 온수 층의 온도를 측정하는 다수개의 온도센서(TE-09 내지 TE-12)가 구비되어 있으며, 축열회로(C2)를 통하여 상기 히트펌프(200)의 응축기(220)와 접촉하도록 연결되어 있다. 온수축열 탱크(300)는 밀폐식 탱크와 개방식 탱크가 사용될 수 있다.The hot water storage tank 300 stores hot water heated by the condenser 220, and uses a density difference according to the temperature of the water to diffuse and store the water of low temperature and the water of high temperature up and down. It is designed to have a, a plurality of temperature sensors (TE-09 to TE-12) for measuring the temperature of each hot water layer therein, and through the heat storage circuit (C2) of the heat pump 200 Connected to contact with the condenser 220. The hot water storage tank 300 may be a closed tank and an open tank.

축열회로(C2)는 응축기(220)와 온수축열 탱크(300) 사이를 순환하는 온수를 이송하는 제2펌프(P2), 온수축열 탱크(300)에서 응축기(220)로 들어가는 물의 온도를 측정하는 제4 온도센서(TE-04), 응축기(220)에서 가열되어 온수축열 탱크로 들어가는 물의 온도를 측정하는 제3 온도센서(TE-03) 및 응축기(220)를 통과하여 온수축열 탱크(300)로 공급되는 유량과 응축기(220)로 되돌아 가는 유량을 조절하는 제1 삼방변(3-way valve, 310)으로 구성되어 있다.The heat storage circuit C2 measures the temperature of the water entering the condenser 220 in the second pump P2 for transferring hot water circulating between the condenser 220 and the hot water storage tank 300, and the hot water storage tank 300. The fourth temperature sensor (TE-04) and the hot water storage tank 300 through the third temperature sensor (TE-03) and the condenser 220 to measure the temperature of the water heated in the condenser 220 to enter the hot water storage tank. It is composed of a first three-way valve (310) for regulating the flow rate supplied to the flow rate and the flow back to the condenser 220.

온수축열 탱크(300)의 하부에 있는 저온의 온수는 축열회로(C2) 상에 구비되어 있는 제2펌프(P2)를 통하여 응축기(220)로 이송하고, 응축기(220)에 도달한 온수는 응축기(220)를 통하여 배출되는 폐열을 흡수하여 가열된 후, 다시 온수축열 탱크(300)의 상부로 들어간다. The low temperature hot water in the lower portion of the hot water storage tank 300 is transferred to the condenser 220 through the second pump P2 provided on the heat storage circuit C2, and the hot water reaching the condenser 220 is condenser. The waste heat discharged through the 220 is absorbed and heated, and then enters the upper portion of the warm water storage tank 300 again.

이때, 축열회로(C2) 상에 구비되어 있는 제3 온도센서(TE-03) 및 제4 온도센서(TE-04)는 응축기(220)로 들어가는 물의 온도와 응축기(220)로부터 흘러나오는 물의 온도를 측정하여 온도조절기(미도시)로 전달하고, 상기 온도조절기는 제1 삼방변의 각 접속구에 흐르는 유량을 제어하여 축열회로(C2)에 흐르는 물이 일정한 온도가 유지되도록 한다.At this time, the third temperature sensor (TE-03) and the fourth temperature sensor (TE-04) provided on the heat storage circuit (C2) is the temperature of the water entering the condenser 220 and the temperature of the water flowing out of the condenser 220 It is measured and delivered to a temperature controller (not shown), and the temperature controller controls the flow rate flowing through each connection port of the first three sides to maintain a constant temperature of water flowing in the heat storage circuit (C2).

예를 들어, 온수축열 탱크(300)에 저장하고자 하는 온수가 60℃인데, 제3 온도센서(TE-03)에서 검출되는 온도가 60℃ 이하인 경우에는, 제1 삼방변(310)에서 B방향으로 통하는 밸브를 폐쇄하고, C방향으로 흐르는 밸브를 개방하여 온수가 온수축열 탱크(300)로 유입되지 않고 전량 응축기(220)로 되돌아 가게 한다. 온수축열 탱크(300)로 들어가는 온수가 온수축열 탱크(300)의 상부에 저장되어 있는 온수보다 온도가 낮은 경우에는 온수축열 탱크(300)에 저장되는 온수가 온도에 의한 층상구조를 유지할 수 없기 때문이다.For example, when the hot water to be stored in the hot water heat storage tank 300 is 60 ° C., and the temperature detected by the third temperature sensor TE-03 is 60 ° C. or less, in the B direction in the first three-way side 310. By closing the valve connected to, and opening the valve flowing in the C direction so that the hot water does not flow into the hot water storage tank 300 to return to the total condenser 220. When the hot water entering the hot water storage tank 300 is lower than the hot water stored in the upper portion of the hot water storage tank 300 is because the hot water stored in the hot water storage tank 300 can not maintain the layered structure by the temperature. to be.

또한, 제4 온도센서(TE-04)에서 검출되는 온수의 온도가 설정온도, 예를 들어 55℃이하인 경우에는, 제1 삼방변(310)의 밸브를 조절하여 응축기(220)를 통하여 가열된 온수 중 일부 온수는 온수축열 탱크(300)로 보내고, 일부 온수는 C방향으로 흐르도록 우회시켜 온수축열 탱크(300)로부터 흘러나오는 온수와 섞이게 하여, 응축기(220)로 흘러들어가는 온수의 온도를 설정온도, 예를 들어 55℃까지 올려준다. 응축기(220)로 유입되는 온수의 온도가 설정온도보다 낮은 경우에는 응축기(220)를 통하여 가열하더라도 원하는 온도를 얻을 수 없기 때문이다.In addition, when the temperature of the hot water detected by the fourth temperature sensor TE-04 is set temperature, for example, 55 ° C. or less, the valve of the first three-way valve 310 is adjusted to be heated through the condenser 220. Some of the hot water is sent to the hot water storage tank 300, the hot water is bypassed to flow in the C direction to mix with the hot water flowing from the hot water storage tank 300, to set the temperature of the hot water flowing into the condenser 220 Raise the temperature to 55 ° C. If the temperature of the hot water flowing into the condenser 220 is lower than the set temperature, even if heated through the condenser 220 is not able to obtain the desired temperature.

한편, 온수축열 탱크(300)에 저장된 온수가 상층부에서 하층부까지 모두 설정온도, 예를 들어 60℃가 되면 온수축열 탱크(300)로 들어가는 온수를 모두 차단하고, 응축기(220)를 통과하여 나오는 온수는 냉각탑(400)를 통하여 냉각하게 되는데, 이에 관하여는 후술하기로 한다.On the other hand, when the hot water stored in the hot water storage tank 300 is all set temperature, for example, 60 ℃ from the upper layer to the lower layer block all the hot water entering the hot water storage tank 300, and the hot water coming out through the condenser 220 Is cooled through the cooling tower 400, which will be described later.

냉각탑(400)은 히트펌프(200)에서 발생하는 온수가 온수축열 탱크(300)에 저장이 완료되면 나머지 열을 외기로 방출하는데 사용되며, 냉각탑(400)으로 온수가 들어가는 온수유입관(410)은 응축기(220)와 제1 삼방변(310)을 연결하는 관 사이에 연결되어 있으며, 상기 온수유입관(410)에는 온수의 흐름을 단속할 수 있는 냉각탑밸브(430)가 설치되어 있고, 냉각탑(400)을 거쳐서 냉각된 물이 나오는 냉수유출 관(420)은 제1 삼방변(310)과 제2 펌프(P2)를 연결하는 관 사이에 연결되어 있다.Cooling tower 400 is used to discharge the remaining heat to the outside when the hot water generated in the heat pump 200 is stored in the hot water storage tank 300, the hot water inlet pipe 410 that enters the hot water into the cooling tower 400 Is connected between the condenser 220 and the pipe connecting the first three-sided 310, the hot water inlet pipe 410 is provided with a cooling tower valve 430 to control the flow of hot water, the cooling tower Cold water outlet pipe 420, the water cooled through the 400 is connected between the first three-way 310 and the pipe connecting the second pump (P2).

응축기(220)를 통하여 가열된 온수가 온수축열 탱크(300)의 상층부에서 하층부까지 저장이 완료되면, 삼방변(310)으로 들어가는 밸브는 폐쇄하고, 냉각탑(400)으로 들어가는 온수유입관(410)에 구비되어 있는 냉각탑밸브(430)가 개방된다. 상기 과정을 통하여 응축기(220)에서 가열된 온수는 냉각탑(400)으로 흐르게 되고, 냉각탑에서 외기로 열을 방출하면서 냉각된 후 다시 응축기(220)로 되돌아 간다.When the hot water heated through the condenser 220 is completed from the upper layer to the lower layer of the hot water storage tank 300, the valve entering the three-way valve 310 is closed and the hot water inflow pipe 410 entering the cooling tower 400 is closed. Cooling tower valve 430 provided in the is opened. Through the above process, the hot water heated in the condenser 220 flows to the cooling tower 400, is cooled while releasing heat to the outside from the cooling tower, and then returns to the condenser 220 again.

한편, 열교환기(500)는 온수축열 탱크(300)에 저장되어 있는 열을 난방 또는 급탕에 사용할 온수를 가열하는데 사용되며, 가열회로(C3)를 통하여 온수축열 탱크(300)와 연결되어 있다. 가열회로(C3)는 온수축열 탱크(300)에 저장되어 있는 온수를 열교환기(500)로 공급하는 제3 펌프(P3), 온수축열 탱크(300)에서 열교환기(500)로 흐르는 온수의 온도를 측정하는 제5 온도센서(TE-05) 및 열교환기(500)를 통하여 실내에서 회수한 온수를 가열하고 온수축열 탱크(300)로 되돌아 가는 온수의 온도를 측정하는 제6 온도센서(TE-06)로 구성되어 있다.On the other hand, the heat exchanger 500 is used to heat the hot water to be used for heating or hot water using the heat stored in the hot water storage tank 300, is connected to the hot water storage tank 300 through the heating circuit (C3). The heating circuit C3 includes a third pump P3 for supplying hot water stored in the hot water storage tank 300 to the heat exchanger 500, and a temperature of the hot water flowing from the hot water storage tank 300 to the heat exchanger 500. The fifth temperature sensor (TE-05) for measuring the temperature and the sixth temperature sensor (TE-) for heating the hot water recovered in the room through the heat exchanger 500 and measuring the temperature of the hot water returned to the hot water storage tank (300) 06).

또한, 열교환기(500)에는 실내에서 사용하고 회수된 온수가 재가열되기 위하여 열교환기로 들어오는 온수회수관(520)과 열교환기(500)를 통과하면서 가열된 온수가 실내로 들어가는 온수공급관(510)이 연결되어 있으며, 상기 온수공급관(510) 및 온수회수관(520)에는 각각 온도센서(TE-07, TE-08)가 구비되어 있다.In addition, the heat exchanger 500 has a hot water supply pipe 510 which is used indoors and the heated hot water is passed through the heat exchanger 500 and the hot water supply pipe 510 entering the heat exchanger in order to reheat the recovered hot water. The hot water supply pipe 510 and the hot water collection pipe 520 are provided with temperature sensors TE-07 and TE-08, respectively.

제3 펌프(P3)는 온수축열 탱크(300)에 저장되어 있는 온수를 열교환기(500)로 공급하는 역할을 한다. 이 경우 제5 온도센서(TE-05), 제6 온도센서(TE-06), 제 7 온도센서 또는 제8 온도센서(TE-08)에서 검출되는 온도를 이용하여 제3 펌프(P3)의 가동을 조절할 수 있다.The third pump P3 serves to supply hot water stored in the hot water heat storage tank 300 to the heat exchanger 500. In this case, the temperature of the third pump P3 is measured by using the temperature detected by the fifth temperature sensor TE-05, the sixth temperature sensor TE-06, the seventh temperature sensor, or the eighth temperature sensor TE-08. The operation can be adjusted.

예를 들어 온수축열 탱크(300)에 저장되어 있는 온수가 60℃이고, 온수회수관(520)을 통하여 회수되는 45℃의 온수를 57℃의 온수로 가열하고자 하는 경우, 제5 온도센서에서 검출되는 온도가 57℃보다 낮은 경우 또는 제8 온도센서에서 검출되는 온도가 57℃보다 높은 경우에는 열교환에 의한 온수가열을 할 수 없거나 원하는 온도를 얻을 수 없으므로 제3펌프(P3)의 가동을 중단하며, 제6 온도센서(TE-06)에서 검출되는 온도가 설정온도보다 높은 경우에는 열교환기(500)로 공급하는 온수의 양을 줄이고, 제7 온도센서(TE-07)에서 검출되는 온도가 설정온도보다 낮은 경우에는 열교환기(500)로 공급하는 온수의 양을 늘릴 수 있다.For example, when the hot water stored in the hot water storage tank 300 is 60 ° C., and wants to heat 45 ° C. hot water recovered through the hot water collection pipe 520 with 57 ° C. hot water, the fifth temperature sensor detects the hot water. If the temperature is lower than 57 ℃ or if the temperature detected by the eighth temperature sensor is higher than 57 ℃ hot water heating by heat exchange is not possible or the desired temperature can not be obtained, the operation of the third pump (P3) is stopped. When the temperature detected by the sixth temperature sensor TE-06 is higher than the set temperature, the amount of hot water supplied to the heat exchanger 500 is reduced, and the temperature detected by the seventh temperature sensor TE-07 is set. If it is lower than the temperature, the amount of hot water supplied to the heat exchanger 500 may be increased.

결과적으로, 히트펌프(200)를 사용하여, 증발기(240)는 냉수를 생산하여 냉동창고(100)를 냉각시키고, 응축기(220)는 온수를 생산하여 온수축열 탱크(300)에 저장해 두었다가 필요한 경우에 열교환기(500)를 통하여 실내로 온수를 공급하므로써, 히트펌프를 이용한 냉동, 냉장 및 난방을 구현할 수 있다.As a result, using the heat pump 200, the evaporator 240 to produce cold water to cool the freezer 100, the condenser 220 to produce hot water stored in the hot water storage tank 300, if necessary By supplying hot water to the room through the heat exchanger 500, the refrigeration, refrigeration and heating using a heat pump can be implemented.

The refrigerant inlet pipe 460 into which the refrigerant enters the cooler 450 is connected between the compressor 210 and the pipe connecting the condenser 220, and the connection point has a second three-way side (3) for controlling the flow of the refrigerant. A -way valve 480 is installed, and the refrigerant outlet pipe 470 from which the refrigerant cooled through the cooler 450 comes out is connected between the condenser 220 and the tube connecting the expansion valve 230.

응축기(220)를 통하여 가열된 온수가 온수축열 탱크(300)의 상층부에서 하층부까지 저장이 완료되면, 제1 삼방변(310)으로 들어가는 밸브는 폐쇄되고, 축열회로(C2) 상에 구비되어 있는 제2펌프(P2)는 가동이 중단된다. 그리고 제2 삼방변(480)은 응축기(220)로 들어가는 밸브를 폐쇄하고, 냉각기(450)로 들어가는 밸브를 개방한다. 상기 과정을 통하여 냉매는 냉각기(450) 방향으로 흐르게 되고, 냉각기(450) 내에 설치되어 있는 열교환기(미도시)를 통하여 외기로 열을 방출하면서 냉각된 후 다시 팽창밸브(230)로 흐르게 된다.When the hot water heated through the condenser 220 is stored from the upper layer to the lower layer of the hot water storage tank 300, the valve entering the first three-way valve 310 is closed and is provided on the heat storage circuit C2. The second pump P2 is suspended. The second three-way 480 closes the valve entering the condenser 220 and opens the valve entering the cooler 450. Through the above process, the refrigerant flows in the direction of the cooler 450, is cooled while releasing heat to outside air through a heat exchanger (not shown) installed in the cooler 450, and then flows back to the expansion valve 230.
