It is about.
일반적으로 냉장고는 일정한 냉동사이클의 순환원리에 의해 냉랜가 순환되어 냉동실의 온도를 저하시킨 고, 냉동실의 냉기가 냉장고 내부의 냉동실과 냉장실을 순환하면서 냉장고 내부의 보관 식품물 냉동 및 냉장시킨 게 되는데, 이러한 종래 냉동사이클을 제1도에 도시한 바, 이에 대해 설명하면 다음과 같다.In general, the refrigerator is circulated by the cooling principle of a certain refrigeration cycle to lower the temperature of the freezer, the cold of the freezer circulates the freezer and the freezer inside the refrigerator to freeze and refrigerate the food stored in the refrigerator, This conventional refrigeration cycle is shown in FIG. 1, which will be described below.
제1도는 종래 냉장고용 냉동사이클장치를 도시한 개략도로서, 도시된 바와 같이, 종래 냉장고의 냉동사이클장치는 냉매가스가 고압상태로 유지되어 순환하는 고 할부와, 냉매가스가 저압상태로 유지되어 순환하는 저압부가 연결되어 사이클을 이루고 있다.1 is a schematic view showing a conventional refrigeration cycle apparatus for a refrigerator, as shown, the conventional refrigeration cycle apparatus of the refrigerator is a high portion of the refrigerant gas is maintained at a high pressure state and circulating, the refrigerant gas is maintained at a low pressure state and circulated The low pressure unit is connected to form a cycle.
상기 고압부는 저온저압의 기체상태의 냉()H를 고온고뜹의 기체상태의 냉매로 변화시키는 압축기(1)와, 그 압축긴(1)에서 변화된 고온고압의 기체상태의 냉매를 상온고압의 액체상태의 냉매로 응축시킨 는 응축기(2)로 구성되어 있다.The high-pressure unit is a compressor (1) for changing the low-temperature low-pressure gaseous cold () H into a high-temperature, high-pressure gaseous refrigerant, and the high-temperature, high-pressure gaseous refrigerant changed in the compressor (1) is a liquid of room temperature and high pressure The condenser 2 is condensed with a refrigerant in a state.
그리고 상기 저압부는 상기 응축기(2)를 거친 상온고압의 액체냉매를 단열 팽창시켜 저온저압의 액체냉매로 변화시키는 팽창기구(3)와, 그 팽창기구(3)에서 변화된 저온저압의 액체상태의 냉매를 기체상태로 변화시키면서 외부의 열을 흡수하여 열교환하는 증발기(4)로 구성되어 있다.The low pressure unit expands the liquid refrigerant of room temperature and high pressure through the condenser 2 to adiabaticly expands the liquid refrigerant into a low temperature low pressure liquid refrigerant, and the low temperature and low pressure liquid refrigerant changed in the expansion mechanism 3. It is composed of an evaporator (4) that absorbs heat from the outside while changing it to a gas state.
이와 같이 구성된 종래 냉장고의 냉동사이클장치는 냉장고에 전원을 인가하면 압축기(1)가 작동하면서 냉매가스가 고압부와 저압부를 통해 사이클을 순환하면서 냉각기능을 발휘하게 되는데, 먼저 고압부에서 냉매가 충분히 충전된 후 저압부로 유입되어야 냉각성능이 나오게 된다.In the conventional refrigeration cycle apparatus of the refrigerator configured as described above, when power is applied to the refrigerator, the compressor 1 operates and the refrigerant gas circulates through the high pressure and low pressure sections, thereby exerting a cooling function. After entering the low pressure part, the cooling performance comes out.
즉, 냉동사이클의 증발기(4)에서 액체상태의 냉매가 기체상태의 냉매가스로 변환하면서 외부의 열을 흡수하는 것을 이용하여 냉장고 내부의 온도를 차갑게 유지하는 것이다.That is, in the evaporator 4 of the refrigerating cycle, the refrigerant in the liquid state is converted into gaseous refrigerant gas to absorb the heat from the outside, thereby keeping the temperature inside the refrigerator cold.
제2도는 종래 기술에 의한 냉장고용 냉동사이클의 몰리에르 선도로서, A-B 구간은 압축기(11)에서 냉매가 압축되는 압축과정이고, B-C 구간은 응축기(12)에서 냉매가 응축되는 응축과정, C-D 구간은 모세관(13)71서 냉매가 팽증되는 과정, D-E 구간은 증발기(14)에서 액체냉매가 증발하여 실제적으로 냉동효과를 얻는 증발과정 이다.2 is a Moliere diagram of a refrigerator refrigeration cycle according to the prior art, AB section is a compression process of the refrigerant is compressed in the compressor (11), BC section is a condensation process of the refrigerant is condensed in the condenser 12, CD section is The process of expanding the refrigerant in the capillary tube (13) 71, DE section is an evaporation process of the liquid refrigerant evaporates in the evaporator 14 to actually obtain a freezing effect.
상긴 E점 이후의 구간은 비록 증발이 완료된 기체냉매 구간이지만, 기체 냉매의 온도가 증발기(14)를 통과하는 냉동실 내의 공기몬도와 거의 동등하긴 때문에 실제 냉동효과는 거두지 못하고 있으므로, 실제의 냉동효과는 D-E 구간의 h1-h3의 열량이다.Although the section after the long point E is a gas refrigerant section in which evaporation is completed, since the temperature of the gas refrigerant is almost the same as that of the air monoxide in the freezer compartment passing through the evaporator 14, the actual freezing effect is not achieved. The amount of heat in h1-h3 of the DE section.
그러나, 상술한 바와 같은 종래 기술은 비교적 고압의 상태에서 증발기(4)가 외부의 열을 흡입하여 냉매를 기화시켜야 하므로, 냉동사이클의 주요 목적인 증발기(4)에서 주위로부터의 열량을 최대한 흡수하는데 한계가 발생하는 문제점이 있었다.However, the prior art as described above is limited to absorbing the maximum amount of heat from the surroundings in the evaporator 4, which is the main purpose of the refrigerating cycle, since the evaporator 4 must vaporize the refrigerant by sucking external heat at a relatively high pressure. There was a problem that occurred.
따라서, 본 고안은 상기 문제점을 감안하여 안출된 것으로, 냉매의 압력을 감소시켜 주위로부터의 열량을 최대한 흡수하여 증발기의 기화작용을 극대화시켜 냉장고의 냉각효과를 향상시킬 수 있는 냉장고용 냉동사이클장치를 제공하는데 그 목적이 있다.Therefore, the present invention has been made in view of the above problems, by reducing the pressure of the refrigerant to maximize the evaporation of the evaporator by absorbing the maximum amount of heat from the surroundings to improve the cooling effect of the refrigerator refrigeration cycle apparatus for the refrigerator The purpose is to provide.

이하, 본 고안에 의한 냉장고용 냉동사이클장치의 실시예를 첨부된 도면에 의거하여 설명하면 다음과 같다.Hereinafter, an embodiment of a refrigeration cycle apparatus for a refrigerator according to the present invention will be described with reference to the accompanying drawings.
제3도는 본 고안에 의한 냉장고용 냉동사이클장치를 보인 개략도로서, 이에 도시된 바와 같이, 본 고안의 냉동사이클장치는 냉매를 흡수하여 고온고압으로 압축하는 압축기(11)와, 그 압축긴(11)에서 고온고압으로 압축된 냉매를 공기중에 방열하여 액화시키는 응축기(12)와, 그 응축기(12)에서 유입된 액체냉매를 감압하는 팽창기구(13)와, 그 팽층기구(13)를 통과한 저온저압의 액체냉매를 증발시켜 고내를 냉각시키는 증발기(14)와, 상기 각 구성요소들에 연결 설치되어 냉매의 이동통로가 되는 냉매관(15)으로 구성된다.3 is a schematic view showing a refrigeration cycle apparatus for a refrigerator according to the present invention, as shown in the present invention, the refrigeration cycle apparatus of the present invention absorbs a refrigerant and compresses it to a high temperature and high pressure, and the compressor (11) Pass through the condenser 12 for liquefying and liquefying the refrigerant compressed to high temperature and high pressure in the air, the expansion mechanism 13 for depressurizing the liquid refrigerant introduced from the condenser 12, and the expansion mechanism 13 It consists of an evaporator 14 for evaporating the liquid refrigerant of low temperature low pressure to cool the inside of the refrigerant, and a refrigerant pipe 15 connected to each of the above components to be a moving passage of the refrigerant.
그리고 상기 응축기(12)의 상기 팽창기구(13)측 단부에는 압축기(11)를 통과한 냉매의 압력을 감소시키기 위해 냉매관(15)의 직경보다 작은 소정 길이의 모세관으로 형성된 강압관(12a)을 연통 형성한다.The pressure drop 12a formed at the end of the expansion mechanism 13 side of the condenser 12 is formed of a capillary tube having a predetermined length smaller than the diameter of the refrigerant pipe 15 to reduce the pressure of the refrigerant passing through the compressor 11. To form communication.
상기와 같이 구성된 본 고안에 의한 냉장고용 냉동사이클의 작용에 대해서 설명하면 다음과 같다.Referring to the operation of the refrigerator refrigeration cycle according to the present invention configured as described above are as follows.
냉장고의 냉동사이클장치는 냉장고에 전원을 인가하면 압축기(11)가 작동하면서 냉매가스가 고압부와 저압부를 통해 사이클을 순환하면서 냉각기능을 발후하게 되는데 먼저 고압부에서 냉매가 충분히 충전된 후 저압부로 유입되어야 냉각성이 나오게 된다.When the refrigeration cycle device of the refrigerator applies power to the refrigerator, the compressor 11 operates and the refrigerant gas circulates through the high pressure and low pressure sections, thereby generating a cooling function. First, the refrigerant is sufficiently charged in the high pressure section and then flows into the low pressure section. Cooling comes out.
즉, 냉동사이클 과정에서 증발기(14)에서 액체상태의 냉매가 기체상태의 냉매로 변화할 때 변화가 가장 잘 일어나는 상태는 저온저압의 상태이므로, 상기 압축기(11)에서 고온고압으로 압축된 냉매를 공기중에 방열시켜 액화시킨 는 응축기(12)의 일단부에 연통 형성된 감압관(12a)에 의해 압축된 냉매의 압력을 감소시켜 고내의 주위로부터 열량(h1-h3')을 최대한 흡입하여 방열 액화시킴으로써 액화된 냉매를 기화시키기 위한 증발기(14)의 열교환 성능을 향상시켜 냉장고의 냉각효율 을 극대화시킨다.That is, when the liquid refrigerant in the evaporator 14 changes into a gaseous refrigerant in the refrigeration cycle, the state where change occurs best is a low temperature and low pressure state, and thus the refrigerant compressed at high temperature and high pressure in the compressor 11 is used. By reducing the pressure of the refrigerant compressed by the pressure-sensitive tube 12a formed in communication with one end of the condenser 12, which is liquefied by dissipating in air, by maximizing the heat (h1-h3 ') from the circumference of the inside of the furnace, By improving the heat exchange performance of the evaporator 14 for vaporizing the liquefied refrigerant to maximize the cooling efficiency of the refrigerator.
즉 제4도에 도시된 바와 같이, 종래 냉장고의 냉동효과를 이루는 구간은 h1-h3에 해당하는 부분의 냉매에너지이지만, 본 고안에 의한 냉동사이클장치는 응축기에서 1차적으로 냉매를 강압시켜 h1-h3'에 해당하는 부분만큼 주위의 열을 흡입하여 증발기(14)에서 열교환을 하므로 최대한의 냉동효과를 얻을 수 있다.That is, as shown in Figure 4, the conventional refrigeration effect of the refrigerator is a section of the refrigerant energy corresponding to h1-h3, but the refrigeration cycle apparatus according to the present invention is to first step down the refrigerant in the condenser to h1- Since the heat is sucked in the evaporator 14 by sucking the heat around the portion corresponding to h3 'can obtain the maximum freezing effect.
이상에서와 같이 본 고안에 의한 냉장고용 냉동사이클장치는, 응축기의 일단부에 감압관을 연통 형성하텁 압축기로부터 나온 고압축의 냉매의 압력을 감압시켜 증발기에서 주위의 열량을 최대한 흡입하여 냉장고의 냉각효과를 향상시킨다.As described above, the refrigeration cycle apparatus for a refrigerator according to the present invention forms a pressure-sensitive tube at one end of the condenser, thereby reducing the pressure of the high-compression refrigerant from the compressor, and sucking the amount of heat from the evaporator to maximize the cooling effect of the refrigerator. To improve.
