종래의 공기압축기에 내장된 냉동식 에어 드라이어는 단일 증발기(Single Evaporator)로써 오직 냉동식 에어 드라이어 기능만으로 구성된 것을 공기압축기 케이스 내부 공간에 설치한 형식이다.The refrigeration air dryer built in the conventional air compressor is a single evaporator (Single Evaporator) consisting of only the function of the refrigeration air dryer installed in the space inside the air compressor case.

이것은 단순히 공기압축기 후단에 독립적으로 설치된 것을 설치 장소만 공기압축기 케이스 내부로 이동시킨 것에 불과하다.This is simply moving the installation site to the inside of the air compressor case is installed independently of the rear of the air compressor.

본 발명은 종래의 공기압축기 내장형 냉동식 에어 드라이어에서는 제공할 수 없는 다중 증발기를 사용하여 압축공기 냉각 제습의 기본 기능은 물론, 공기압축기의 윤활유 냉각 성능을 크게 향상시키기 위한 오일 쿨러용 증발기 및 공기압축기 흡입 공기 냉각용 증발기를 동시에 갖춘 다중 증발기를 갖는 공기압축기 내장형 고온용 냉동식 에어 드라이어를 제공하는데 그 목적이 있다.The present invention is an oil cooler evaporator and air compressor to greatly improve the lubricating oil cooling performance of the air compressor, as well as the basic function of the compressed air cooling dehumidification using a multiple evaporator that can not be provided in the conventional air compressor built-in refrigeration air dryer It is an object of the present invention to provide a high temperature refrigeration air dryer with a built-in air compressor having multiple evaporators simultaneously equipped with an evaporator for intake air cooling.

본 발명의 공기압축기 내장형 냉동식 에어 드라이어는 압축공기의 냉각 제습은 기본적으로 수행하고, 더 나아가 공기압축기의 윤활유 냉각 성능을 크게 향상시키기 위한 오일 쿨러용 증발기 및 공기압축기 흡입 공기 냉각용 증발기를 동시에 갖춘 다중 증발기를 갖는 것을 특징으로 한다.The refrigeration air dryer built-in air compressor of the present invention basically performs cooling and dehumidification of compressed air, and is further equipped with an evaporator for an oil cooler and an evaporator for intake air cooling to greatly improve the lubricating oil cooling performance of the air compressor. It is characterized by having multiple evaporators.

여기서, 냉매 압축기와 응축기는 각각 한 대씩이고 증발기는 에어 드라이어용, 오일 쿨러용 및 공기압축기 흡입 공기 냉각용 증발기 등 다중으로 구성하고, 팽창장치(모세관 또는 팽창밸브)는 다중 증발기에 대해 각각의 독립된 팽창장치로 구성되어 동작되는 것을 특징으로 한다.Here, one refrigerant compressor and one condenser and the evaporator is composed of multiples such as an air dryer, an oil cooler and an air compressor evaporator for intake air cooling, and an expansion device (capillary tube or expansion valve) is independent of each other for the multiple evaporators. It is characterized in that the operation is configured as an expansion device.

본 발명은 냉동시스템에 의한 압축공기 냉각 제습은 물론 다중 증발기에 의한 공기압축기 윤활유 냉각과 흡입 공기 냉각이 가능하기 때문에 무더운 하절기에도 공기압축기의 윤활유 고유 기능을 보장할 수가 있고, 흡입 공기의 밀도를 높게 유지할 수 있어 체적효율이 제고되어 공기압축기의 에너지 효율 증대와 내구성 향상이 가능하다.The present invention can guarantee the air compressor's lubricating oil cooling and intake air cooling by multiple evaporator as well as dehumidifying the compressed air by the refrigeration system, thereby ensuring the inherent function of the lubricating oil of the air compressor even in the hot summer season, and the density of the intake air is high. It is possible to maintain the volumetric efficiency to increase the energy efficiency and durability of the air compressor.

특히 냉동시스템의 응축기를 분리형(Remote Condensing Unit) 으로 설계할 경우에는 공기압축기의 공간활용과 열(Heat) 문제에 매우 효과적으로 대응할 수 있다.In particular, if the condenser of the refrigeration system is designed as a remote condensing unit, it can effectively cope with the space utilization and heat problems of the air compressor.

본 발명을 첨부된 도1을 참조하여 상세히 설명하면 다음과 같다.Referring to the present invention with reference to the accompanying Figure 1 as follows.

본 발명은 냉매압축기(Refrigerant Compressor)(1), 응축기(Condenser)(2)와 에어 드라이어(Refrigerated Air Dryer)용 팽창장치(Expansion Device)(7)와 증발기(Evaporator)(8) 그리고 오일쿨러(Oil Cooler)용 팽창장치(Expansion Device)(3)와 증발기(Evaporator)(4) 및 공기압축기 흡입공기(Intake Air) 냉각용 팽창장치(Expansion Device)(5)와 증발기(Evaporator)(6) 등으로 구성된다.The present invention relates to a refrigerant compressor (1), a condenser (2) and an expansion device (7), an evaporator (8) and an oil cooler (Refrigerated Air Dryer). Expansion device (3) and evaporator (4) for oil cooler (4) and intake air (Intake Air) cooling device (5) and evaporator (6), etc. It consists of.

여기서, 팽장장치(Expansion Device)와 증발기(Evaporator)는 오일쿨러용, 흡입공기 냉각용 및 에어 드라이어용 등의 다중으로 구성된다.Here, the expansion device and the evaporator are composed of a plurality of oil coolers, intake air cooling, and air dryers.

냉매 압축기(1)에서 압력과 온도가 상승된 고온?고압의 기체상태의 냉매는 응축기(2)에서 냉각매체(공기 또는 냉각수)를 통해 열을 방출하는 발열과정이 일어나면서 냉각되어 액체상태의 냉매로 상변화가 이루어진다.In the refrigerant compressor 1, a high-temperature, high-pressure gaseous refrigerant in which the pressure and temperature are elevated is cooled while an exothermic process of releasing heat from the condenser 2 through a cooling medium (air or cooling water) occurs, thereby cooling the liquid refrigerant. Phase change occurs.

계속해서 팽창장치(모세관 또는 팽창밸브)(3)(5)(7)에서 팽창에 의해 냉매의 압력이 강하된 상태로 냉매가 증발기(Evaporator)(4)(6)(8)로 유입되면, 설계된 증발온도에서 액체냉매의 증발이 일어나면서 증발기 주변으로부터 냉매가 열을 흡수하는 흡열과정이 일어난 후 다시 기체 상태로 변화되어 냉매 압축기(1)로 흡입되는 사이클이 반복된다.Subsequently, when the refrigerant flows into the evaporator 4, 6, 8 while the pressure of the refrigerant is lowered by expansion in the expansion device (capillary tube or expansion valve) 3, 5, 7, As the evaporation of the liquid refrigerant occurs at the designed evaporation temperature, an endothermic process in which the refrigerant absorbs heat from the surroundings of the evaporator occurs, and then the cycle is changed into a gas state and sucked into the refrigerant compressor 1.

여기서, 공기압축기의 윤활유 냉각을 더욱 효과적으로 하기 위하여 오일쿨러(Oil Cooler)용 팽창장치(Expansion Device)(3)와 증발기(Evaporator)(4)를 사용하면, 오일쿨러의 냉각 공기를 차갑게 할 수 있기 때문에 윤활유 냉각 효율을 높일 수 있다.Here, the expansion device (3) and the evaporator (4) for the oil cooler (Oil Cooler) can be used to cool the cooling oil of the air compressor more effectively. Therefore, lubricating oil cooling efficiency can be improved.

또한 공기압축기 흡입공기(Intake Air) 냉각용 팽창장치(Expansion Device)(5)와 증발기(Evaporator)(6)를 사용하면, 공기압축기 내부의 온도를 낮출 수 있으므로 공기압축기로 흡입되는 공기의 밀도가 높게 되어 공기압축기의 체적효율이 개선된다.In addition, the use of an expansion device (5) and an evaporator (6) for cooling the intake air can reduce the temperature inside the air compressor. Higher the volumetric efficiency of the air compressor.

그리고 에어 드라이어(Refrigerated Air Dryer)용 팽창장치(Expansion Device)(7)와 증발기(Evaporator)(8)를 통해 본래의 기본 기능인 압축공기 냉각 제습을 수행한다.And through the expansion device (7) and the evaporator (8) for the air dryer (Refrigerated Air Dryer) performs the compressed air cooling dehumidification, which is an original basic function.

한편 냉매압축기(1)와 응축기(2)를 분리형(Remote Condensing Unit) 으로 설계하여 공기압축기 케이스 바깥에 설치할 경우에는 공기압축기의 공간활용과 열(Heat) 문제를 매우 효과적으로 대처할 수 있다.Meanwhile, when the refrigerant compressor 1 and the condenser 2 are designed as remote condensing units and installed outside the air compressor case, the space utilization and heat of the air compressor can be coped with very effectively.
