Description
본 발명은 히트펌프용 냉수/온수 발생 시스템에 관한 것으로, 더욱 상세하게는 동시에 냉수와 온수를 발생시켜 각각의 냉수/온수탱크에 집수하여 필요시 공급할 수 있는 히트펌프용 동시 냉수/온수 발생 시스템에 관한 것이다.The present invention relates to a cold water / hot water generation system for a heat pump, and more particularly to a simultaneous cold water / hot water generation system for a heat pump that generates cold water and hot water to be collected in each cold water / hot water tank and supplied when necessary It is about.
일반적으로 히트펌프의 원리는 액체가 기화할 때 기화열을 흡수하고, 역으로 기체가 응축되어 액화할 때는 열을 방출하는 성질을 갖는다.In general, the principle of the heat pump absorbs the heat of vaporization when the liquid vaporizes, and consequently emits heat when the gas condenses and liquefies.
이러한 성질을 이용하여 압축-응축-팽창-증발의 사이클을 순환시키면 필요한 냉/난방 열을 얻게 되는데 압축기에서 압축된 가스냉매를 응축기에서 액화시킨 뒤, 팽창밸브를 통해 팽창시켜 저압으로 만든 후 증발기에서 기화시켜 흡수되는 냉매의 기화열에 의해 증발기 주위에 대하여 냉각작용을 수행하게 되는 것이다.Using this property, the cycle of compression-condensation-expansion-evaporation obtains the required heating / cooling heat. The compressed gas refrigerant in the compressor is liquefied in the condenser, expanded through an expansion valve to low pressure, and then in the evaporator. Cooling is performed around the evaporator by the heat of vaporization of the refrigerant absorbed by vaporization.
도 1은 상기의 냉매가스의 사이클을 갖는 히트펌프의 흐름을 나타낸 개략도로써, 압축기(10)에서 고압/고온으로 압축된 냉매가스는 응축기(20)로 흐르게 된다. 상기 응축기(20)에서 액화된 냉매가스는 제1팽창밸브(30)를 통과하면서 저압의 상태로 리시버 탱크(40)에 유입된다.1 is a schematic view showing a flow of a heat pump having a cycle of the refrigerant gas, in which the refrigerant gas compressed at high pressure / high temperature in the compressor 10 flows to the condenser 20. The refrigerant gas liquefied in the condenser 20 is introduced into the receiver tank 40 at a low pressure while passing through the first expansion valve 30.
상기 리시버 탱크(40)에 유입된 냉매가스는 제2팽창밸브(50)에서 저압된 후 증발기(60)에서 기화된 냉매가스에 의해 대기와 열교환을 이루고 압축기(10)로 유입하게 된다.The refrigerant gas introduced into the receiver tank 40 is low-pressured by the second expansion valve 50 and then exchanges heat with the atmosphere by the refrigerant gas vaporized in the evaporator 60 and flows into the compressor 10.
종래에는 대형 목욕탕이나 온수와 냉수의 수요가 많은 곳에서는 보일러를 설치하여 화력에 의하여 온수를 발생시켰으며, 냉수의 경우에는 별도의 냉장장치를 설치하여, 상수를 냉장장치로 통과시켜 냉수를 생성하였다.Conventionally, in a large bathroom or a place where hot water and cold water are in high demand, a boiler was installed to generate hot water by thermal power, and in the case of cold water, a separate refrigeration unit was installed and water was passed through the refrigerating unit to generate cold water. .
그러나 이러한, 종래의 온수/냉수를 생성시키기 위해서는 기름(가스) 보일러와 냉장장치를 별도로 설치하여야 하며, 온수를 생성시키기 위해서는 기름이나 가스를 태워야 했으므로 과다한 운영비의 지출을 발생시켰다.However, in order to generate such hot water / cold water, an oil (gas) boiler and a refrigeration apparatus must be separately installed, and in order to generate hot water, oil or gas had to be burned, thus incurring excessive operating expenses.
또한, 온수와 냉수를 생성시키는 장치가 별개로 작동하기 때문에 설치장소와 점검이 수월치 못하는 문제점이 있었다.In addition, there is a problem that the installation place and the inspection is not easy because the device for generating hot water and cold water operates separately.
그리하여 이러한 문제점을 보완하고자 근래에 들어 히트펌프를 이용한 온수/냉수 생성 시스템이 보급되고 있는 추세이다.Thus, in order to supplement these problems, a hot water / cold water generation system using a heat pump has recently been spreading.
본 발명은 상기와 같은 문제점을 해결하기 위한 것으로, 히트펌프의 사이클을 이용해 대량의 온수와 냉수를 생성시켜 집수하여 사용자에게 공급할 수 있는 히트펌프용 냉수/온수 발생 시스템를 제공하는데 그 목적이 있다.An object of the present invention is to provide a cold water / hot water generation system for a heat pump that can generate and collect a large amount of hot water and cold water by using a cycle of a heat pump and supply the collected water to a user.
상기와 같은 목적을 달성하기 위한 본 발명의 기술적 사상으로는, 냉매가스가 고압/고온으로 압축하는 압축기로 공급되어, 상기 압축기로 부터 공급된 냉매가스가 열교환되는 제1열교환기로 흘러, 상기 제1열교환기의 냉매가스와 상온수가 열교환 되어 온수탱크에 저정되며, 상기 제1열교환기로 부터 공급된 냉매가스가 액화상태로 저장되는 리시버탱크로 흘러, 상기 리시버탱크로 부터 공급된 냉매가스가 제1팽창밸브를 통과하면서 팽창된 상태로 증발기로 공급되어 압축기로 순환되는 온수발생수단과, 상기 리시버탱크와 증발기의 사이에서 분기되어 전자변의 온/오프에 의해 냉매가스가 팽창밸브를 통과하면서 팽창된 상태로 제2열교환기에 공급되어, 상온수가 열교환 되어 냉수탱크에 저장되며, 상기 제2열교환기로 부터 공급된 냉매가스가 증발기와 압축기 사이의 배관으로 역류되지 않도록 흐르는 냉수발생수단을 포함하는 히트펌프용 냉수/온수 발생 시스템의 구성에 의해 달성된다.According to the technical idea of the present invention for achieving the above object, the refrigerant gas is supplied to the compressor to compress the high pressure / high temperature, the refrigerant gas supplied from the compressor flows to the first heat exchanger to heat exchange, The refrigerant gas of the heat exchanger and the normal temperature water are exchanged and stored in the hot water tank, and the refrigerant gas supplied from the first heat exchanger flows into the receiver tank where the refrigerant gas is stored in a liquefied state, and the refrigerant gas supplied from the receiver tank is first expanded. The hot water generating means which is supplied to the evaporator in the expanded state while passing through the valve and circulated to the compressor, and branched between the receiver tank and the evaporator, in a state in which the refrigerant gas is expanded while passing through the expansion valve by on / off of the electromagnetic valve. Supplied to the second heat exchanger, the room temperature water is heat-exchanged and stored in the cold water tank, the refrigerant gas supplied from the second heat exchanger is evaporator It is achieved by the configuration of the cold water / hot water generation system for a heat pump comprising a cold water generating means flowing so as not to flow back into the pipe between the compressor and the compressor.
또한, 상기 냉수탱크와 온수탱크에 설치된 각각의 열교환기가 직렬배관으로 다수개설치된 것이 더욱 바람직하다.In addition, it is more preferable that each of the heat exchangers installed in the cold water tank and the hot water tank is provided in plural in series piping.
이하, 본 발명에 따른 바람직한 실시예를 첨부된 도면에 따라 보다 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.
이하의 설명에서, 본 발명의 보다 철저한 이해를 위해 도면을 통한 설명이 추가되나 당업자에게는 본 발명이 이들의 상세한 설명이 없이도 실시될 수도 있다는 사실이 명백할 것이다. In the following description, for the purposes of thorough understanding of the present invention, descriptions are added to the drawings, but it will be apparent to those skilled in the art that the present invention may be practiced without these specific details.
경우에 따라서는, 본 발명의 요지를 불필요하게 흐리게 할 수 있는 공지된 특징부 내지 요소들에 대해서는 그 설명을 생략하였다. 이것은 본 발명의 개시를 불필요하게 애매하게 하는 것을 피하기 위한 것이다.In some cases, descriptions of well-known features or elements that may unnecessarily obscure the subject matter of the present invention have been omitted. This is to avoid unnecessarily obscuring the disclosure of the present invention.
도 2는 본 발명에 따른 히트펌프용 냉수/온수 발생 시스템을 나타낸 개략도이다. Figure 2 is a schematic diagram showing a cold water / hot water generation system for a heat pump according to the present invention.
냉매가스가 충진된 압축기(100)에서 냉매가스를 고압으로 가압하면 냉매가스의 온도는 상승한 체로 제1열교환기(200)로 공급된다. 그리고 제1열교환기(200)와 인접한 영역에 상온수를 공급받아 저장하는 온수탱크(300)가 설치된다. 상기한 제1열교환기(200)는 고온의 냉매가스와 상온수가 서로 열교환을 이루어 온수탱크(300)에 저장하게 된다. 여기서 상기 제1열교환기(200)는 온수탱크(300)와 직렬로 다수개 설치되는 것이 바람직하다.When the refrigerant gas is filled with the refrigerant gas to pressurize the refrigerant gas to a high pressure, the temperature of the refrigerant gas is supplied to the first heat exchanger 200 in a sieve. And a hot water tank 300 for receiving and storing the normal temperature water in the area adjacent to the first heat exchanger 200 is installed. The first heat exchanger 200 is a high-temperature refrigerant gas and the room temperature water to exchange heat with each other to be stored in the hot water tank (300). Here, the first heat exchanger 200 is preferably installed in plurality in series with the hot water tank (300).
상기, 제1열교환기(200)에서 온수탱크(300)와 열교환을 일으킨 냉매가스는 리시버탱크(400)로 저장된다. 액화상태로 리시버탱크(400)에 저장된 냉매가스는 다시 증발기(800)로 흘러 증발된 후 압축기(100)로 공급되어 온수를 생성시키는 온수발생수단으로 작동된다. 이때 증발기(800)에서 발생된 열원은 필요에 따라 실내에 공급할 수도 있다.In the first heat exchanger 200, the refrigerant gas causing heat exchange with the hot water tank 300 is stored in the receiver tank 400. The refrigerant gas stored in the receiver tank 400 in the liquefied state is flowed back to the evaporator 800 and evaporated and then supplied to the compressor 100 to operate hot water generating means for generating hot water. At this time, the heat source generated from the evaporator 800 may be supplied to the room as needed.
또한, 상기 리시버탱크(400)에서 공급되는 냉매가스는 리시버탱크(400)와 증발기(800)사이에서 분기를 이루어 제2열교환기(600)으로 흐르게 된다. 이때, 제2열교환기(600)으로 흐르기전에 제1팽창밸브(500)에서 냉매가스는 기화된 상태로 제2열교환기(600)으로 공급된다. 이렇게 저온의 냉매가스가 흐르는 제2열교환기(600)에는 온수발생수단에서와 같은 상온수를 공급받아 저장하는 냉수탱크(700)가 설치된다. 따라서, 제2열교환기(600)의 저온의 냉매가스와 냉수탱크(700)에서 공급받은 상온수는 열교환되어 상온수의 열을 냉매가스가 빼앗아 냉수가 생성되어 냉수발생수단으로 작동된다.In addition, the refrigerant gas supplied from the receiver tank 400 flows to the second heat exchanger 600 by branching between the receiver tank 400 and the evaporator 800. At this time, the refrigerant gas from the first expansion valve 500 is supplied to the second heat exchanger 600 in a vaporized state before flowing to the second heat exchanger 600. In this way, the second heat exchanger 600 through which the low-temperature refrigerant gas flows is provided with a cold water tank 700 for receiving and storing normal temperature water as in the hot water generating means. Accordingly, the low temperature refrigerant gas of the second heat exchanger 600 and the normal temperature water supplied from the cold water tank 700 are heat-exchanged to extract the heat of the normal temperature water, thereby generating the cold water to operate the cold water generating means.
그리고 제2열교환기(600)에서 열교환된 냉매가스는 증발기(800)와 압축기(100)사이로 공급된다. 이때, 증발기(800)와 압축기(100)로 냉매가스가 공급될때, 제2열교환기(600)로 냉매가스가 역류하지 못하도록 역류방지밸브가 설치된다. 또한, 냉매가스의 분기를 제어하기 위해 전자변을 설치하는 것은 당업자라면 당연한 것이라 하겠다.The refrigerant gas heat-exchanged in the second heat exchanger 600 is supplied between the evaporator 800 and the compressor 100. At this time, when the refrigerant gas is supplied to the evaporator 800 and the compressor 100, a non-return valve is installed to prevent the refrigerant gas from flowing back to the second heat exchanger 600. In addition, it will be obvious to those skilled in the art to provide an electron valve to control the branching of the refrigerant gas.
이와 같이 본 발명은, 상업용으로 온수와 냉수가 필요로 하는 대중 목욕탕과 같은 곳에 히트펌프의 사이클을 이용해 대량의 온수와 냉수를 생성시켜 집수시켜 사용자에게 공급하므로 기름보일러나 가스보일러 등과 같이 과다한 운영비를 절감할 수 있으며, 온수발생수단과 냉수발생수단이 히트펌프의 사이클로 작동되기 때문에 온수발생수단과 냉수발생수단에 포함된 설비의 점검시에도 편의를 제공하게 된다. As described above, the present invention generates a large amount of hot water and cold water by using a cycle of a heat pump in a public bath where hot water and cold water are required for commercial use, and collects and supplies the user with excessive operating costs such as an oil boiler or a gas boiler. Since the hot water generating means and the cold water generating means are operated in a cycle of the heat pump, the hot water generating means and the cold water generating means are provided with convenience even when checking the facilities included in the hot water generating means and the cold water generating means.
한편, 본 발명은 상술한 실시예로서만 한정되는 것이 아니라 본 발명의 요지를 벗어나지 않는 범위내에서 수정 및 변형하여 실시할 수 있고, 그러한 수정 및 변형이 가해진 기술사상 역시 이하의 특허청구범위에 속하는 것으로 보아야 한다. On the other hand, the present invention is not limited only to the above-described embodiment, but can be modified and modified within the scope not departing from the gist of the present invention, the technical idea that such modifications and variations are also included in the claims Should be seen.
