본 발명은 보텍스 튜브(Vortex Tube)의 에너지 분리 현상을 이용한 캔음료 자동판매기에 관한 것으로서 소비전력의 증가를 억제하면서 차가운 음료와 더운 음료를 동시에 저장하여 판매하는 것이다.The present invention relates to a can drink vending machine using the energy separation phenomenon of the vortex tube (Vortex Tube) and to store and sell cold and hot drinks at the same time while suppressing the increase in power consumption.
종래의 캔음료 자동판매기는 압축기, 증발기, 응축기, 팽창장치로 구성된 증기 압축식 냉동 시스템(Vapor Compression Refrigeration System)을 이용하여 캔 음료를 냉장 저장하여 판매하고 있다.Conventional can drink vending machines sell canned beverages by refrigeration using a Vapor Compression Refrigeration System composed of a compressor, an evaporator, a condenser, and an expansion device.
증기 압축식 냉동 시스템의 싸이클을 설명하면 다음과 같다. 압축기에서 압축된 냉매는 고온고압의 과열증기 상태가 되고 응축기를 지나면서 주위의 공기에 에너지를 전달하여 고압의 과냉액 상태가 된다. 고압의 과냉액 상태의 냉매는 팽창장치를 지나면서 압력이 감소하여 저압의 2상 상태의 냉매로 변하게 된 후 증발기를 거치면서 저압의 과열증기가 되어 다시 압축기로 돌아가 싸이클을 완성하게 된다.The cycle of the vapor compression refrigeration system is described as follows. The refrigerant compressed in the compressor becomes a superheated steam state at high temperature and high pressure, and transfers energy to the surrounding air while passing through the condenser to become a high pressure supercooled liquid state. The refrigerant in the high-pressure supercooled liquid state decreases as it passes through the expansion device and is converted into a low-pressure two-phase refrigerant, and then passes through an evaporator to become a low-pressure superheated steam to return to the compressor to complete the cycle.
이러한 싸이클 중 증발기를 지나는 냉매는 주위의 공기로부터 열을 빼앗아 주위의 공기온도를 낮추게 되며, 온도가 낮아진 공기를 이용하여 캔음료를 냉장 저장하게 된다. 또한, 캔음료를 온장저장하여 판매하기 위하여 증기 압축식 냉동시스템 이외에 전기히터를 사용하고 있다.The refrigerant passing through the evaporator in the cycle takes heat away from the surrounding air to lower the ambient air temperature, and the canned beverage is refrigerated by using the lower temperature air. In addition, in order to store and sell canned beverages, electric heaters are used in addition to the vapor compression refrigeration system.
종래의 증기 압축식 냉동시스템을 사용하는 경우, 캔음료의 냉장 저장과 온장 저장을 동시에 하기 위해서는 증발 온도를 캔음료를 냉장 저장할 수 있을만큼 충분히 낮은 온도를 유지하면서 응축온도에 캔음료를 저장하기에 적당할 만큼 높은 온도를 유지하는데 어려움이 있는 문제점이 있다.In the case of using the conventional vapor compression refrigeration system, to store the canned beverage at the condensation temperature while keeping the evaporation temperature low enough to refrigerate the canned beverage in order to simultaneously store the canned beverage at the same time. There is a problem in that it is difficult to maintain a moderately high temperature.
즉 응축온도를 높이게 되면 증기 압축식 싸이클의 전체 압력이 상승하게 되어 증발온도도 상승되어 캔음료를 냉장저장할 수 없는 온도까지 상승하게 된다.In other words, if the condensation temperature is increased, the total pressure of the steam compression cycle is increased, and the evaporation temperature is also increased to a temperature at which the canned beverage cannot be refrigerated.
또한 증발온도를 기존의 낮은 온도로 유지하면서 응축온도를 높이려면 응축압력과 증발압력의 비율인 압축비가 커지게 되며 이는 증기 압축식 냉동시스템을 구동시키는 압축기 소요동력을 증가시켜서 효율이 나빠지게 된다. 따라서 증기 압축식 냉동 시스템을 사용하는 경우에는 캔음료를 냉장 저장함과 동시에 온장 저장할 수 있는 자동판매기를 제작하는데 어려움이 따르며 이를 극복하기 위하여 전기 히터를 별도로 부착하여 캔음료의 온장 저장에 이용하고 있다. 전기 히터의 경우에 에너지 효율이 매우 낮아 냉장 저장과 온장 저장을 동시에 하는 자동 판매기는 소비 전력이 증가하는 문제점이 있다.In addition, to increase the condensation temperature while maintaining the evaporation temperature, the compression ratio, which is the ratio of the condensation pressure and the evaporation pressure, becomes large, which increases the power consumption of the compressor driving the steam compression refrigeration system, resulting in poor efficiency. Therefore, in the case of using a vapor compression refrigeration system, it is difficult to manufacture a vending machine that can store and store the canned beverage at the same time as a cold storage. To overcome this problem, an electric heater is separately attached and used for the stored storage of the canned beverage. In the case of an electric heater, a very low energy efficiency has a problem in that the vending machine for both cold storage and warm storage simultaneously increases power consumption.
본 발명은 이러한 점을 감안하여 발명된 것으로서, 보텍스 튜브의 에너지 분리 현상을 이용하여 소비 전력의 증가를 억제하면서 차가운 음료와 더운 음료를 동시에 저장하여 판매하는 것이다.The present invention has been invented in view of such a point, and simultaneously stores and sells cold and hot beverages while suppressing an increase in power consumption by using an energy separation phenomenon of a vortex tube.
따라서 이를 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Therefore, it will be described in detail with reference to the accompanying drawings as follows.
제 1 도에 나타낸 바와 같이 본 발명은 보텍스 튜브(103)의 에너지 분리현상을 이용하므로 별도의 냉매가 필요 없으며, 따라서 냉매 압축기 대신 공기를 압축하는 공기압축기(102)가 필요하고 증발기, 응축기, 팽창장치 등은 필요없다. 제 1 도에서 공기압축기(102)를 지난 고압의 공기는 보텍스 튜브(103)에 유입되고 보텍스 튜브(103)에 유입된 압축공기는 보텍스 튜브(103)내의 외부와류와 내부와류의 에너지 손실 및 획득에 의해 고온의 공기와 저온의 공기로 나누어진다. 찬 공기는 캔음료를 냉장보관하는 공간에 공급되어 캔 음료를 저온으로 유지시키고, 더운공기는 온장 보관하는 공간에 유입되어 캔 음료를 고온으로 유지시킨다.As shown in FIG. 1, the present invention uses an energy separation phenomenon of the vortex tube 103 so that a separate refrigerant is not required. Therefore, an air compressor 102 for compressing air instead of a refrigerant compressor is needed, and an evaporator, a condenser, and an expansion are required. No device is required. In FIG. 1, the high-pressure air passing through the air compressor 102 flows into the vortex tube 103 and the compressed air introduced into the vortex tube 103 loses and acquires energy of the external and internal vortices in the vortex tube 103. It is divided into hot air and low temperature air. Cold air is supplied to the storage space of the canned beverage to keep the canned beverage at a low temperature, and hot air is introduced to the heated storage space to keep the canned beverage at a high temperature.
이때 찬공기와 더운공기의 유량은 고온공기 토출구에 부착된 유량조절밸브를 이용하여 조절한다. 유량조절밸브를 많이 열수록 더운공기의 유량은 증가하고 찬공기의 유량은 감소하게 되며, 반대로 유량조절밸브를 닫을수록 더운공기의 유량은 감소하고 찬공기의 유량은 증가하게 된다. 여름철에는 캔음료를 냉장 저장하는 요구가 온장 저장하는 요구보다 많으므로 유량조절밸브를 닫아 찬공기의 유량을 증가시키고, 반대로 겨울철에는 온장 저장하는 경우가 더욱 많아지므로 유량조절밸브를 열어 더운공기의 유량을 증가시킬 수 있으므로 한 대의 자동판매기를 이용하여 계절에 맞는 요구사항을 만족시킬 수 있는 효과가 있다.At this time, the flow rate of cold and hot air is controlled using a flow control valve attached to the hot air outlet. The more the flow control valve is opened, the hot air flow rate increases and the cold air flow rate decreases. On the contrary, when the flow control valve is closed, the hot air flow rate decreases and the cold air flow rate increases. In summer, the demand for refrigeration of canned beverages is greater than the demand for hot storage, so the flow control valve is closed to increase the flow rate of cold air. On the contrary, in winter, the flow of hot air is increased by opening the flow control valve. Since it can increase the use of a single vending machine is effective to meet the requirements of the season.
