냉장고의 부하대응 운전방법{METHOD FOR OPERATING LOAD MATCH OF REFRIGERATOR}How to respond to load of refrigerator {METHOD FOR OPERATING LOAD MATCH OF REFRIGERATOR}

본 발명은 냉장고의 부하대응 운전방법에 관한 것으로, 특히 냉동실 증발기 입구에 서로 다른 유량 저항값을 가진 2개의 모세관을 설치하여 증발온도를 제어할 수 있도록 한 냉장고의 부하대응 운전방법에 관한 것이다.The present invention relates to a load response operation method of a refrigerator, and more particularly, to a load response operation method of a refrigerator for controlling evaporation temperature by installing two capillaries having different flow resistance values at an inlet of a freezer compartment evaporator.

일반적으로 냉동사이클 장치는, 도 1에 도시한 바와 같이, 작동유체, 즉 냉매를 압축하여 고온 고압 상태로 변환시키는 압축기(10)와; 상기 압축기(10)에서 압축된 고온 고압 상태의 냉매를 액상으로 변환시키면서 내부 잠열을 외부로 방출시키는 응축기(20)와; 상기 응축기(20)에서 액상으로 변환된 냉매의 압력을 저하시키는 모세관(30)과; 상기 모세관(30)에서 팽창된 액체 상태의 냉매를 기체로 증발시키면서 외부의 열을 흡수하는 증발기(40)를 포함하여 구성된다. 상기 응축기(20)와 증발기(40)는 외부와의 열교환을 이루게 되므로 열교환기라고도 한다.In general, the refrigeration cycle apparatus, as shown in Figure 1, the compressor 10 for compressing the working fluid, that is, the refrigerant to a high temperature and high pressure state; A condenser 20 for discharging internal latent heat to the outside while converting the refrigerant in the high temperature and high pressure state compressed by the compressor 10 into a liquid phase; A capillary tube 30 for lowering the pressure of the refrigerant converted into the liquid phase in the condenser 20; The evaporator 40 absorbs external heat while evaporating the liquid refrigerant expanded in the capillary tube to gas. The condenser 20 and the evaporator 40 is also called a heat exchanger because the heat exchange with the outside.

이와 같은 냉동사이클 장치의 압축기(10)는 저온, 저압의 기체 냉매를 흡입하여 고온, 고압으로 압축하게 되고, 그 고온, 고압의 기체는 응축기(20)로 들어가 냉각수 또는 공기에 의해 열교환되어 상온 고압의 액체 상태의 냉매가 된다.The compressor 10 of the refrigerating cycle apparatus sucks gas refrigerant of low temperature and low pressure and compresses the gas refrigerant at high temperature and high pressure. The gas of high temperature and high pressure enters the condenser 20 and is heat-exchanged by cooling water or air to obtain room temperature and high pressure. It becomes the liquid refrigerant of the liquid state.

상기 상온 고압의 액체 상태의 냉매는 증발기(40)로 보내기 전에 미리 증발하기 쉬운 상태로까지 압력을 내리는 작용과 액체의 냉매의 유량을 제어하는 모세관을 거쳐 저온 저압의 액체 상태의 냉매가 된다.The liquid refrigerant at room temperature and high pressure becomes a liquid refrigerant at low temperature and low pressure through a capillary for controlling the flow rate of the refrigerant and the action of lowering the pressure to a state which is easy to evaporate before being sent to the evaporator 40 in advance.

상기 저온 저압의 액체 상태의 냉매는 상기 증발기(40)에 의해 열을 흡수한다. 이에 의해 열을 빼앗긴 공기는 냉각되어 자연 대류 또는 팬에 의해서 순환하여 냉장고를 저온으로 유지한다.The low temperature low pressure liquid refrigerant absorbs heat by the evaporator 40. The air deprived of heat is thereby cooled and circulated by natural convection or a fan to keep the refrigerator at a low temperature.

따라서, 냉장고와 냉동고의 기능을 동시에 수행하면서 음식물을 보관할 수 있도록 하였다.Therefore, it is possible to store food while simultaneously performing the functions of a refrigerator and a freezer.

그러나, 상기와 같이 동작하는 종래 기술은 냉동실 증발기 입구에 유량 저항이 일정한 모세관을 두어 고내 부하가 안정되도록 냉매 유량을 조절하여 겨울철, 여름철에 따라 고내온도를 일정온도로 유지시켜야 해야 하는데 이때 여름철은 겨울철에 비해 많은 냉매 유량을 증가시켜야 하게 때문에 에너지 효율이 저감되는 문제점이 있었다.However, the prior art operating as described above should maintain a constant temperature according to the winter and summer by adjusting the refrigerant flow rate to stabilize the high load by placing a capillary tube with a constant flow resistance at the inlet of the freezer compartment evaporator. Compared to the above, there is a problem in that energy efficiency is reduced because much refrigerant flow rate must be increased.

따라서, 본 발명은 상기와 같은 문제점을 해결하기 위하여 창안한 것으로, 유량 저항이 다른 모세관을 구비하여 냉장고 고내에 사용자가 큰 부하를 투입하거나 혹은 외기 온도 상승으로 인한 냉장고 시스템의 부하상승시에 유량저항이 작은 모세관을 통하여 냉매를 순환시키고, 이와는 반대로 상기 냉장고의 고내 부하가 안정이 되어 있거나, 그 냉장고의 시스템의 부하가 작은 겨울철이나 혹은 야간에 냉장고 사용시에는 유량 저항이 큰 모세관을 통해 냉매를 공급함으로써, 증발기의 증발 온도를 낮게 제어하여 냉매 순환량을 줄여 압축기의 입력을 저감하여 에너지 효율을 향상시킬 수 있도록 한 냉장고의 부하대응 운전방법을 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, the flow resistance is provided when the user puts a large load in the refrigerator refrigerator or the load rise of the refrigerator system due to the rise of the outside temperature due to the capillary tube with different flow resistance By circulating the refrigerant through a small capillary tube, on the contrary, when the internal load of the refrigerator is stabilized or when the refrigerator is used in the winter or at night when the load of the system of the refrigerator is small, the refrigerant is supplied through a large flow resistance capillary tube, It is an object of the present invention to provide a load response operation method of a refrigerator to control the evaporation temperature of the evaporator to reduce the amount of refrigerant circulation to reduce the input of the compressor to improve energy efficiency.

도 2는 본 발명 냉장고의 부하대응 운전방법이 적용되는 장치의 구성을 보인 예시도로서, 이에 도시한 바와 같이 작동유체, 즉 냉매를 압축하여 고온 고압 상태로 변환시키는 압축기(21)와; 상기 압축기(21)에서 압축된 고온 고압 상태의 냉매를 액상으로 변환시키면서 내부 잠열을 외부로 방출시키는 응축기(22)와; 냉장고의 고내 부하가 안정이 되어 있는 상태에서는 제1 경로를 제공하고, 그 냉장고의 고내 부하가 급격한 부하 변동이 있을때 제2 경로를 제공하여 상기 응축기(22)의 냉매를 제어하는 삼방밸브(23)와; 상기 삼방밸브(23)를 통해 제공된 상기 제1 경로의 냉매순환량을 줄여서 출력하는 제1 모세관(24a)과; 상기 삼방밸브(23)를 통해 제공된 상기 제2 경로의 냉매순환량을 증가시켜 출력하는 제2 모세관(24b)과; 상기 제1, 제2 모세관(24a, 24b)의 액체 상태의 냉매를 기체로 증발시키면서 외부의 열을 흡수하는 증발기(25)를 포함하여 구성하며, 이와 같이 구성된 본 발명의 동작을 설명하면 다음과 같다.Figure 2 is an exemplary view showing the configuration of the apparatus to which the load response operation method of the present invention is applied, a compressor (21) for compressing the working fluid, that is, the refrigerant to convert to a high temperature and high pressure state as shown therein; A condenser 22 for discharging internal latent heat to the outside while converting the refrigerant of the high temperature and high pressure state compressed by the compressor 21 into a liquid phase; The three-way valve 23 provides a first path when the internal load of the refrigerator is stable, and provides a second path when the internal load of the refrigerator suddenly changes, thereby controlling the refrigerant in the condenser 22. Wow; A first capillary tube (24a) for reducing and outputting the refrigerant circulation amount of the first path provided through the three-way valve (23); A second capillary tube 24b that increases and outputs a refrigerant circulation amount of the second path provided through the three-way valve 23; And an evaporator 25 for absorbing external heat while evaporating the liquid refrigerant in the first and second capillary tubes 24a and 24b with gas. The operation of the present invention configured as described above will be described below. same.

먼저, 압축기(21)는 냉매를 압축하여 고온 고압 상태의 냉매가스로 변환시켜 응축기(22)로 출력한다.First, the compressor 21 compresses the refrigerant, converts the refrigerant into a refrigerant gas in a high temperature and high pressure state, and outputs the refrigerant gas to the condenser 22.

상기 응축기(22)는 상기 고온 고압 상태의 냉매가스를 상온의 액체 상태의 냉매로 변환시키는 동시에 내부의 잠열을 외부로 방출시킨다.The condenser 22 converts the refrigerant gas in a high temperature and high pressure state into a refrigerant in a liquid state at room temperature and simultaneously releases latent heat therein.

이때, 상기 응축기(22)의 상온의 액체 상태의 냉매는 냉장실 고내의 온도 또는 냉장실 외기 온도에 따라 경로를 달리하게 되는데, 이는 냉매 흐름을 제어하는 삼방밸브(23)에 의해 가능하게 된다.At this time, the refrigerant in the liquid state at room temperature of the condenser 22 changes the path depending on the temperature in the refrigerator compartment or the outside temperature of the refrigerator compartment, which is enabled by the three-way valve 23 to control the refrigerant flow.

상기 삼방밸브(23)는 상기 냉장고의 고내 온도가 그 냉장고의 사용자가 큰부하를 투입하거나, 혹은 외기 온도 상승등의 냉장고의 고내 부하상승시 유량 저항이 작은 모세관(24b)을 통해 냉매의 경로를 제공하여 증발기(25)의 증발 온도를 상승시켜 냉매 순환량을 증가시켜준다.The three-way valve 23 routes the refrigerant through a capillary tube 24b having a low flow resistance when the internal temperature of the refrigerator puts a large load by the user of the refrigerator, or when the internal load of the refrigerator rises, such as an outside temperature rise. Provided to increase the evaporation temperature of the evaporator 25 to increase the refrigerant circulation amount.

이와는 반대로 상기 냉장고의 고내 부하가 안정이 되어 있거나, 그 냉장고의 고내 부하가 작은 겨울철이나 혹은 야간에 냉장고를 사용시에는 유량 저항이 큰 모세관(24a)을 통해 냉매의 경로를 제공하여 상기 증발기(25)의 증발 온도를 감소 시켜 냉매순환량을 줄인다.On the contrary, when the refrigerator has a stable internal load, or when the refrigerator has a small internal load in the winter or at night, the refrigerant flows through the capillary tube 24a having a large flow resistance to provide the refrigerant path. Reducing the evaporation temperature of the refrigerant reduces the refrigerant circulation.

이에 의해, 압축기(21)의 압력을 저감하여 에너지 효율을 향상시킨다.This reduces the pressure of the compressor 21 and improves energy efficiency.

본 발명의 냉장고의 부하대응 운전방법은 전술한 실시예에 국한되지 않고 본 발명의 기술사상이 허용하는 범위내에서 다양하게 변형하여 실시할 수 있다.The load-response operation method of the refrigerator of the present invention is not limited to the above-described embodiment, and may be variously modified and implemented within the range permitted by the technical idea of the present invention.

이상에서 상세히 설명한 바와 같이 본 발명은 유량 저항이 다른 모세관을 구비하여 냉장고 고내에 사용자가 큰 부하를 투입하거나 혹은 외기 온도 상승으로 인한 냉장고 시스템의 부하상승시에 유량저항이 작은 모세관을 통하여 냉매를 순환시키고, 이와는 반대로 상기 냉장고의 고내 부하가 안정이 되어 있거나, 그 냉장고의 시스템의 부하가 작은 겨울철이나 혹은 야간에 냉장고 사용시에는 유량 저항이 큰 모세관을 통해 냉매를 공급함으로써, 증발기의 증발 온도를 낮게 제어하여 냉매 순환량을 줄여 압축기의 입력을 저감하여 에너지 효율을 향상시킬 수 있는 효과가 있다.As described in detail above, the present invention includes a capillary tube having a different flow resistance so that the user circulates the refrigerant through a capillary tube having a low flow resistance when the user puts a large load into the refrigerator or the load of the refrigerator system increases due to an increase in the outside temperature. On the contrary, when the internal load of the refrigerator is stabilized or when the refrigerator is used in the winter or at night when the load of the system of the refrigerator is small, the refrigerant is supplied through a capillary tube having a large flow resistance, thereby controlling the evaporator temperature of the evaporator to be lowered. Reducing the amount of refrigerant circulating reduces the input of the compressor has the effect of improving the energy efficiency.
