Description

가습기 겸용 유니트 쿨러{Unit cooler for both humidifier}Unit cooler for both humidifier}

본 발명은 가습기 겸용 유니트 쿨러에 관한 것으로, 상세하게는 저온저장고(저장실온도:0℃이상)의 냉각에 사용되는 증기압축식 냉동기의 증발기로서, 가동중 별도의 동력이나 가습기의 물공급 없이 저온저장고에 수분을 공급하여 저온저장고에 보관되는 물품(야채, 과일, 구근 및 기타 높은 습도가 필요한 물품)을 저장하기에 최적의 습도를 유지할 수 있도록 구성한 것이다.The present invention relates to a unit cooler that doubles as a humidifier, and more specifically, to an evaporator of a vapor compression refrigerator used for cooling low-temperature storage (storage room temperature: 0°C or higher), which can cool the low-temperature storage without separate power or water supply from the humidifier during operation. It is designed to maintain optimal humidity for storing items stored in low-temperature storage (vegetables, fruits, bulbs, and other items requiring high humidity) by supplying moisture to the system.

일반적으로 저온저장고는 각종 농산물을 신선한 상태로 유지하며 장기적으로 보관할 목적으로 사용되는 장치로서, 저장물을 신선한 상태로의 보관에는 온도, 습도, 실내공기의 질등이 최적화되어야 하지만, 온도를 낮출 때 냉각기의 온도가 불가피하게 수분의 노점온도 이하로 유지되기 때문에 공기중의 수분이 결로되어 얼음의 형태로 냉각기에 달라붙는 착상현상이 발생되는 제습 기능도 있어 냉동기를 운전함에 따라 저장고 내부의 수분이 점차적으로 제거되면서 신선 농산물 등의 시듬 현상이 발생되는 것이다.In general, low-temperature storage is a device used to keep various agricultural products fresh and for long-term storage. Temperature, humidity, and indoor air quality must be optimized to store stored products in a fresh state, but when lowering the temperature, a cooler is used. Since the temperature is inevitably maintained below the dew point temperature of moisture, there is also a dehumidifying function that causes moisture in the air to condense and stick to the cooler in the form of ice. As the freezer is operated, the moisture inside the storage gradually decreases. As it is removed, wilting phenomenon occurs in fresh produce, etc.

이와 같은 종래기술에 대한 저장고의 냉동시스템에 하여 첨부되는 도면을 참조로 설명하기로 한다.The storage refrigeration system of this prior art will be described with reference to the attached drawings.

첨부된 도 1은 종래 냉동시스템을 개략적으로 도시한 흐름도이다.The attached Figure 1 is a flow chart schematically showing a conventional refrigeration system.

도시된 바와 같이, 종래 냉동시스템은 저압의 냉매가스를 압축하여 고압의 냉매가스를 생성하기 위한 냉매압축기(100)와; 냉매압축기(100)와 연결되어 고압의 냉매가스를 공급받아 응축기팬(210)을 이용해 열을 제거하여 응축, 액화시키는 응축기(200)와; 응축기(200)와 연결되어 액화된 냉매를 공급받아 응축된 냉매를 팽창시키는 온도식팽창밸브(300)와; 팽창된 냉매가 쿨러팬(410)에 의해 증발되면서 외부의 열을 흡수하는 유니트 쿨러(400)로 이루어진다.As shown, a conventional refrigeration system includes a refrigerant compressor 100 for compressing low-pressure refrigerant gas to generate high-pressure refrigerant gas; A condenser (200) connected to the refrigerant compressor (100) to receive high-pressure refrigerant gas and remove heat using a condenser fan (210) to condense and liquefy it; a thermostatic expansion valve (300) connected to the condenser (200) to receive liquefied refrigerant and expand the condensed refrigerant; It consists of a unit cooler (400) that absorbs external heat as the expanded refrigerant is evaporated by the cooler fan (410).

이때, 응축기(200)와 온도식팽창밸브(300) 사이의 증발기배관라인(102)에는 팽창된 냉매를 유니트 쿨러(400)로 분배하기 위한 냉매 분배기(500)가 설치된다.At this time, a refrigerant distributor 500 is installed in the evaporator piping line 102 between the condenser 200 and the thermostatic expansion valve 300 to distribute the expanded refrigerant to the unit cooler 400.

이와 같이 구성되는 종래의 냉동시스템은, 저압의 냉매가스가 냉매압축기(100)로 공급되어 고압의 냉매가스로 압축 생성한 다음, 고압의 냉매가스를 응축기(200)로 공급되어 응축기팬(210)으로서 응축 및 액화시키고, 응축기(200)에서 액화된 냉매가 증발기냉각배관라인(102)에 설치되는 온도식팽창밸브(300)에 의해 팽창하게 되고, 팽창된 액화 냉매가 냉매 분배기(500)로 공급되어 하단에 결합되는 냉매공급관(530)을 통하여 유니트 쿨러(400)의 냉각관(420)으로 공급이 이루어지고, 쿨러팬(410)에 의해 증발되면서 외부의 열을 흡수하여 냉방을 하게 되고, 열이 흡수된 저압의 냉매가스는 다시 냉매압축기(100)로 공급되어 고온으로 압축되는 순환구조로 동작이 이루어진다.In a conventional refrigeration system configured in this way, low-pressure refrigerant gas is supplied to the refrigerant compressor 100 and compressed to produce high-pressure refrigerant gas, and then the high-pressure refrigerant gas is supplied to the condenser 200 and the condenser fan 210. It is condensed and liquefied, and the liquefied refrigerant in the condenser 200 is expanded by the thermal expansion valve 300 installed in the evaporator cooling piping line 102, and the expanded liquefied refrigerant is supplied to the refrigerant distributor 500. The refrigerant is supplied to the cooling pipe 420 of the unit cooler 400 through the refrigerant supply pipe 530 connected to the bottom, and is evaporated by the cooler fan 410 to absorb external heat and cool the heat. The absorbed low-pressure refrigerant gas is supplied back to the refrigerant compressor 100 and operated in a circulation structure where it is compressed to a high temperature.

그러나 이와 같은 저장고는 온도를 낮출 때 냉각기의 온도가 불가피하게 수분의 노점온도 이하로 유지되기 때문에 공기중의 수분이 결로되어 얼음의 형태로 냉각기에 달라붙는 착상현상이 발생되는 제습 기능도 있어 냉동기를 운전함에 따라 저장고 내부의 수분이 점차로 제거되면서 신선 농산물 등의 시듬 현상이 발생되는 데, 이를 보완하고자 저장고 내부에 가습기를 설치하는 경우도 있고, 저장고 바닥에 물을 뿌리는 것 등의 대처방안이 제공되고 있는데, 이 방법은 별도의 장비 및 시설 등이 필요하여 계속적으로 관리가 되어야 하는 경제적으로 부담이 발생 되는 문제점이 있는 것이다.However, when lowering the temperature of such storage, the temperature of the cooler is inevitably maintained below the dew point temperature of moisture, so it has a dehumidifying function that causes the moisture in the air to condense and stick to the cooler in the form of ice, which causes the freezer to cool. As the operation progresses, moisture inside the storage unit is gradually removed, causing wilting of fresh produce. In some cases, a humidifier is installed inside the storage unit to compensate for this, and countermeasures such as spraying water on the floor of the storage unit are provided. However, this method has the problem of requiring separate equipment and facilities, which creates an economic burden as it must be continuously managed.

본 발명은 이와 같은 종래의 문제점을 해결하기 위하여 안출된 것으로, 본 발명의 목적은 응축기를 통과하여 응축 액화된 액체냉매를 압축기의 토출가스와 액가스 열교환기로서 열교환하여 온도가 높여진 고온 액체냉매가 유니트 쿨러 하부에 설치되는 수증기발생장치로 공급되어 액체 냉매가 냉각되면서 발생되는 수증기에 의해 저온저장고 내부의 습도를 유지하도록 구성한 가습기 겸용 유니트 쿨러를 제공하는 데 있다.The present invention was devised to solve such conventional problems. The purpose of the present invention is to exchange the liquid refrigerant condensed and liquefied after passing through the condenser with the discharge gas of the compressor using a liquid gas heat exchanger to produce a high-temperature liquid refrigerant whose temperature is increased. The aim is to provide a unit cooler that doubles as a humidifier, configured to maintain humidity inside the cold storage by the water vapor generated as the liquid refrigerant is cooled by being supplied to a water vapor generator installed at the bottom of the unit cooler.

이와 같은 목적을 달성하기 위한 과제 해결 수단은 저압의 냉매가스를 압축하여 고압의 냉매가스를 생성하기 위한 냉매압축기와; 냉매압축기와 연결되어 고압의 냉매가스를 공급받아 응축기팬을 이용해 열을 제거하여 응축, 액화시키는 응축기와; 응축기와 연결되어 액화된 냉매를 공급받아 응축된 냉매를 팽창시키는 온도식팽창밸브와; 팽창된 냉매가 쿨러팬에 의해 증발되면서 외부의 열을 흡수하는 유니트 쿨러로 이루어진 냉동시스템에 있어서, 상기 냉매압축기에서 압축 생성된 고온 고압 가스냉매가 유입되어 열교환이 이루어져 온도를 낮추게 되고, 상기 고온 고압 가스냉매가 응축기를 통과하여 고온 액체냉매로 응축 액화된 고온 액체냉매를 열교환하여 온도를 높이기 위한 액가스 열교환기가 응축기의 입구측 및 출구측에 설치되고, 상기 액가스 열교환기에서 온도가 높여진 상기 고온 액체냉매가 액체냉매공급관을 통해 상기 유니트 쿨러 하부에 설치되는 수증기발생장치로 공급되어 냉각되면서 발생되는 수증기에 의해 저온저장고 내부의 습도를 유지하는 것을 특징으로 한다.A means of solving the problem to achieve this goal is a refrigerant compressor for compressing low-pressure refrigerant gas to generate high-pressure refrigerant gas; A condenser connected to a refrigerant compressor to receive high-pressure refrigerant gas and remove heat using a condenser fan to condense and liquefy it; A thermostatic expansion valve connected to the condenser to receive liquefied refrigerant and expand the condensed refrigerant; In a refrigeration system consisting of a unit cooler that absorbs external heat as the expanded refrigerant is evaporated by the cooler fan, the high-temperature, high-pressure gas refrigerant compressed and generated in the refrigerant compressor is introduced, heat exchange occurs, and the temperature is lowered, and the high-temperature, high-pressure A liquid gas heat exchanger is installed on the inlet and outlet sides of the condenser to increase the temperature of the gas refrigerant by passing through the condenser and condensing and liquefying the high temperature liquid refrigerant into a high temperature liquid refrigerant. The high-temperature liquid refrigerant is supplied through a liquid refrigerant supply pipe to a water vapor generator installed at the bottom of the unit cooler, and the humidity inside the low-temperature storage is maintained by the water vapor generated as it cools.

본 발명에 따르면 응축기의 입구측 및 출구측에 설치되는 액가스 열교환기에서 온도가 높아진 고온 액체냉매가, 유니트 쿨러 하부에 설치되는 수증기발생장치의 수조 내부에 수평으로 연장되게 배관된 증기발생관으로 공급되어 하부수조 내부의 냉각수에 의해 냉각됨에 따라 발생되는 수증기가, 유니트 쿨러와 동시에 동작되는 쿨러팬으로서 저온저장고 내부로 공급됨에 따라 실내의 습도(가습)를 유지시켜 저장되는 물품(야채, 과일, 구근 및 기타 높은 습도가 필요한 물품)을 최적의 신선도가 유지되도록 함과 동시에 전기를 절약할 수 있는 효과가 제공된다. According to the present invention, the high-temperature liquid refrigerant whose temperature is increased in the liquid gas heat exchanger installed on the inlet and outlet sides of the condenser is piped to a steam generator pipe piped to extend horizontally inside the water tank of the steam generator installed at the bottom of the unit cooler. The water vapor generated as it is supplied and cooled by the cooling water inside the lower water tank is supplied into the cold storage as a cooler fan that operates simultaneously with the unit cooler, maintaining indoor humidity (humidification) for stored items (vegetables, fruits, This provides the effect of saving electricity while maintaining optimal freshness of bulbs and other items that require high humidity.

이와 같이 구성되는 본 발명에 따른 냉동시스템에 대한 동작상태를 개략적으로 설명하기로 한다.The operating state of the refrigeration system according to the present invention configured as described above will be briefly described.

도 2에서와 같이 유니트 쿨러(40)를 통과한 저압의 냉매가스가 냉매압축기(10)로 공급되어 고온 고압으로 압축 생성된 고온 고압 가스냉매(예시 : 100℃)가 판형 열교환기로 이루어진 액가스 열교환기(50) 내부로 유입되어 열교환이 이루어져 온도(예시 : 70℃)가 낮아진 상태로 응축기(20) 내부로 공급되어 응축기팬(21)에 의해 고온 액체냉매(예시 : 30℃)로 응축 액화된다.As shown in FIG. 2, the low-pressure refrigerant gas that has passed through the unit cooler 40 is supplied to the refrigerant compressor 10, and the high-temperature and high-pressure gas refrigerant (example: 100°C) generated by compression at high temperature and high pressure is used in a liquid-gas heat exchanger consisting of a plate heat exchanger. It flows into the refrigerant (50), undergoes heat exchange, and is supplied to the condenser (20) at a lower temperature (e.g., 70°C), where it is condensed and liquefied into high-temperature liquid refrigerant (e.g., 30°C) by the condenser fan (21). .

이와 같은 응축 액화된 고온 액체냉매가 액가스 열교환기(50) 내부로 유입되어 열교환이 이루어져 온도(예시 : 50℃)로 높아진 상태로 액체냉매공급관(70)을 통하여, 수증기발생장치(60)를 구성하는 수조(62) 내부에 배관된 증기발생관(64)으로 공급되어, 냉각수에 의해 온도가 냉각된 저온 액체냉매(예시 : 10℃)가 냉매배출관(66)을 따라 온도식팽창밸브(30)로 공급이 이루어져 팽창되고, 팽창된 액화 냉매가 냉매 분배기(80)를 통해 유니트 쿨러(40) 내부로 분배되어 공급이 이루어져 쿨러팬(41)에 의해 증발되면서 외부의 열을 흡수하여 냉방을 하게 되고, 열이 흡수된 저압의 냉매가스는 다시 냉매압축기(10)로 공급되어 압축되는 순환구조로 동작이 이루어진다.Such condensed, liquefied, high-temperature liquid refrigerant flows into the liquid gas heat exchanger (50), undergoes heat exchange, and raises the temperature (e.g., 50°C) to the water vapor generator (60) through the liquid refrigerant supply pipe (70). It is supplied to the steam generating pipe 64 piped inside the water tank 62, and the low-temperature liquid refrigerant (example: 10°C) cooled by the cooling water flows through the thermal expansion valve 30 along the refrigerant discharge pipe 66. ) is supplied and expanded, and the expanded liquefied refrigerant is distributed and supplied to the inside of the unit cooler (40) through the refrigerant distributor (80), and is evaporated by the cooler fan (41) to absorb external heat and provide cooling. The operation is carried out in a circulation structure where the low-pressure refrigerant gas from which heat has been absorbed is supplied back to the refrigerant compressor 10 and compressed.

한편, 액가스 열교환기(50)에서 온도가 높여지게 열교환 된 고온 액체냉매(예시 : 50℃)가 액체냉매공급관(70)을 통하여 수증기발생장치(60)로 공급되어 냉동시스템이 설치되는 저온저장고 내부의 습도를 유지하기 위한 동작을 설명하기로 한다.On the other hand, the high-temperature liquid refrigerant (example: 50°C), which has been heat exchanged to increase the temperature in the liquid-gas heat exchanger (50), is supplied to the water vapor generator (60) through the liquid refrigerant supply pipe (70) to a low-temperature storage where a refrigeration system is installed. We will now explain the operation to maintain internal humidity.

도 3 및 도 4에서와 같이 액가스 열교환기(50)에서 온도가 높아진 고온 액체냉매(예시 : 50℃)가, 수조(62) 내부에 수평으로 연장되게 배관된 증기발생관(64)의 일단과 연결되는 액체냉매공급관(70)을 통해 증기발생관(64)으로 공급되어 증기발생관(64)의 타단에 연결되는 냉매배출관(66)으로 배출이 이루어지면서, 수조(62) 내부의 냉각수에 의해 냉각된 저온 액체냉매의 온도(10℃)가 떨어지게 됨에 따라 발생되는 수증기가, 유니트 쿨러(40) 내부로 공급되어 냉방시스템이 설치된 저온저장고 내부로 공급하게 됨에 따라 실내의 습도(가습)를 유지시켜 저장되는 물품을 최적의 상태를 유지시키게 된다.3 and 4, the high-temperature liquid refrigerant (example: 50°C) whose temperature has been increased in the liquid-gas heat exchanger 50 is connected to one end of the steam generation pipe 64 piped to extend horizontally inside the water tank 62. It is supplied to the steam generation pipe 64 through the liquid refrigerant supply pipe 70 connected to the refrigerant and discharged to the refrigerant discharge pipe 66 connected to the other end of the steam generation pipe 64, and is supplied to the cooling water inside the water tank 62. As the temperature (10°C) of the cooled low-temperature liquid refrigerant drops, the water vapor generated is supplied to the inside of the unit cooler (40) and supplied to the inside of the low-temperature storage where the cooling system is installed, thereby maintaining indoor humidity (humidification). This ensures that stored items are maintained in optimal condition.

즉, 수조(62)에서 발생되는 수증기가, 유니트 쿨러(40)의 쿨러팬(41)의 동작에 의해 수증기배출구(62b)를 통해 유니트 쿨러(40) 내부로 유입되어 유니트 쿨러(40)로 공급되는 액화 냉매와 혼합되면서 온도 차이에 의해 발생된 물입자가 동작되는 쿨러팬(41)에 의해 저온저장고로 공급되어 가습을 하게 되고, 저온저장고의 건공기가 상기 쿨러팬(41)에 의해 수조(62)로부터 유입된 수증기와 직접 혼합되거나 일부가 건공기유입구(62a)를 통해 수조로 유입되어, 내부의 수증기와 함께 수증기배출구(62b)를 통해 유니트 쿨러(40)로 배출됨에 따라 저온저장고로 공급되어 가습이 이루어진다.That is, water vapor generated in the water tank 62 flows into the unit cooler 40 through the water vapor outlet 62b by the operation of the cooler fan 41 of the unit cooler 40 and is supplied to the unit cooler 40. Water particles generated by the temperature difference while mixed with the liquefied refrigerant are supplied to the low-temperature storage by the operating cooler fan 41 and humidified, and the dry air in the low-temperature storage is supplied to the water tank ( It is directly mixed with the water vapor flowing in from 62), or part of it flows into the water tank through the dry air inlet (62a), and is discharged to the unit cooler (40) through the water vapor outlet (62b) together with the water vapor inside, thereby supplying it to the low-temperature storage. Humidification is achieved.
