Description
본 고안은 상변화물질을 이용한 축냉식 냉동,냉장고에 관한 것으로서, 보다 상세하게 냉각기에 상변화물질을 봉입하고 심야전기를 사용하여 냉각기를 가동함으로써 축냉효과에 의하여 냉동,냉장을 하는 것에 관한 것이다.The present invention relates to a refrigeration-type freezer, refrigerator using a phase change material, and more particularly, relates to freezing and refrigerating by the effect of the cold storage effect by encapsulating a phase change material in a cooler and operating a cooler using a midnight electric machine.
종래의 냉동,냉장고는 일반전기를 사용하여 냉동기를 가동하기 때문에 전기료 비용부담이 커서 경제적 손실이 큰 문제점이 있었다.Conventional freezers and refrigerators have a problem in that the economic cost is large because the cost of electricity is large because the refrigerator is operated by using general electricity.
또한 종래의 냉동,냉장고는 송풍 냉각 방식으로 저장고를 냉각하기 때문에 냉기로 인하여 저장되는 식품등이 건조하게 되고 식품의 중량이 감소되는 등의 문제점이 있었다.In addition, the conventional freezers and refrigerators have a problem in that foods stored due to cold air are dried and the weight of foods is reduced because the refrigerators are cooled by a ventilation cooling method.
그리고 종래의 냉동,냉장고는 냉각코일에 형성되는 적상을 제거하기 위하여 주기적으로 일정시간 동안 예컨대 전기히타 또는 온수등을 사용하여 제상을 하여야 하기 때문에 저장고내의 온도변화에 의한 식품 신선도 유지에 어려움이 많았으며, 이로 인한 경제적인 손실며, 이로 인한 경제적 손실도 큰 문제점이 있었다.In the conventional freezers and refrigerators, it is difficult to maintain the freshness of foods due to temperature change in the storage room because defrosting is performed periodically for a certain time, for example, by using an electric heater or hot water, in order to remove a drop formed in the cooling coil. As a result, the economic loss caused by this is a big problem.
본 고안은 상기와 같은 종래의 문제점을 해결하기 위하여 창안된 것으로서, 심야전기를 사용함으로써 냉동기 작동 비용을 최소화하며, 상변화물질을 사용하여 간접적으로 저장고를 냉동,냉장함으로써 식품에 미치는 부정적인 영향을 최소화하고, 냉각기를 제상할 필요성을 최소화한 냉동,냉장고를 제공하는 데 있다.The present invention was devised to solve the conventional problems as described above, minimizing the operation cost of the freezer by using a midnight electricity, and minimizes the negative effect on food by indirectly freezing and refrigerating the store using a phase change material. In addition, to provide a refrigerator, a refrigerator that minimizes the need to defrost the cooler.

도2는 도1의 II-II선에 따른 단면도이다.FIG. 2 is a cross-sectional view taken along the line II-II of FIG. 1.
본 고안에 따른 상변화물질을 이용한 축냉식 냉동,냉장고는 심야전기를 사용하여 가동되는 압축기와, 상기 압축기에 의하여 압축된 냉매를 응축하는 응축기와, 상기 응축된 냉매를 팽창시켜 저온으로 떨어뜨리는 팽창밸브와, 상기 저온의 냉매에 의해 열을 빼앗는 냉각기를 구비한 냉동기와; 상기 냉각기내의 냉매와의 열교환에 의하여 상변화되는 상기 냉각기내에 봉입된 상변화물질과; 상기 상변화물질에 의하여 냉동,냉장되는 저장고를 구비한다.The cold storage refrigerator using the phase change material according to the present invention is a compressor operated by using a late-night electric power, a condenser condensing the refrigerant compressed by the compressor, and an expansion valve for expanding the condensed refrigerant to drop to a low temperature And a chiller having a cooler that takes heat away from the low temperature refrigerant; A phase change material encapsulated in the cooler which is changed in phase by heat exchange with a refrigerant in the cooler; It is provided with a reservoir that is frozen and refrigerated by the phase change material.
이하 도면을 참조하여 본 고안에 따른 상변화물질을 이용한 축냉식 냉동,냉장고를 상세히 설명한다.With reference to the drawings will be described in detail the cold storage refrigeration, refrigerator using the phase change material according to the present invention.
도1은 본 고안의 실시예에 따른 상변화물질을 이용한 축냉식 냉동,냉장고를 나타낸 개략도로서, 냉동기와 상변화물질과 저장고를 포함한다.1 is a schematic view showing a cold storage freezer, a refrigerator using a phase change material according to an embodiment of the present invention, and includes a freezer and a phase change material and a reservoir.
냉동기는 압축기(12)와, 응축기(14)와, 팽창밸브(16)와, 냉각기(18)로 이루어진다. 여기서 압축기(12)는 대략 22시부터 08시까지의 심야시간의 가격이 저렴한 심야전기를 사용하여 가동된다. 압축기(12)에 의하여 압축된 냉매는 응축기(14)에서 응축되고, 응축된 냉매는 팽창밸브(16)에서 팽창되어 저온으로 되며, 냉각기(18)를 지나는 동안 열을 흡수하여 기화한다.The refrigerator consists of a compressor 12, a condenser 14, an expansion valve 16, and a cooler 18. In this case, the compressor 12 is operated by using a late night electricity which is inexpensive at midnight hours from about 22:00 to 08:00. The refrigerant compressed by the compressor 12 is condensed in the condenser 14, and the condensed refrigerant is expanded by the expansion valve 16 to a low temperature, and absorbs heat and vaporizes while passing through the cooler 18.
냉각기(18)는 도2에 도시된 바와 같이 냉매(15)가 지나가는 통로인 냉각관(17)과 냉각관(17)주위에 봉입된 상변화물질(19)사이의 열교환에 의하여 상변화물질(19)을 결빙시킨다. 여기서 상변화물질(19)은 열이 가해지면 고체상에서 액체상으로 변화되는 물질로서, 특히 성분을 변화시킴에 따라 필요로 하는 적정의 온도 예컨대 0℃이하에서 상변화(Phase Change)가 발생하는 물질을 사용하는 것이 바람직하다. 이렇게 하면 저장고(20)에서 필요한 적정한 온도 조건에 따라 사용되는 상변화물질의 조성을 달리함으로써 저장고(20)에서 유지하여야 할 온도조건을 용이하게 충족할 수 있다.The cooler 18 is a phase change material by heat exchange between the cooling tube 17, which is a passage through which the refrigerant 15 passes, and the phase change material 19 enclosed around the cooling tube 17, as shown in FIG. Freeze 19). Here, the phase change material 19 is a material that changes from a solid phase to a liquid phase when heat is applied. In particular, the phase change material 19 may be a material in which a phase change occurs at an appropriate temperature, for example, 0 ° C. or lower, as the component is changed. It is preferable to use. This makes it possible to easily meet the temperature conditions to be maintained in the reservoir 20 by varying the composition of the phase change material used in accordance with the appropriate temperature conditions required in the reservoir 20.
이와 같이 심야시간에 작동된 냉동기에 의하여 상변화물질(19)이 결빙되어 축냉되며, 축냉된 상변화물질(19)은 주간에 해빙되면서 저장고(20)내의 온도를 일정하게 유지한다.As described above, the phase change material 19 is frozen by the freezer operated in the late night time, and is cooled, and the cooled phase change material 19 is thawed during the day to maintain a constant temperature in the storage 20.
냉각기(18)는 저장고(20)내에 설치되어 저장고에 저장된 예컨대 식품과 같은 물체를 냉동,저장하는 것으로서, 도1에 도시된 바와 같이 예컨대 저장고(20)내의 천정 또는 측면에 설치하여 자연대류 또는 대향류 방식으로 저장고(20)내의 온도를 효율적으로 일정하게 유지하도록 한다.The cooler 18 is installed in the storage 20 to freeze and store an object such as food stored in the storage. For example, as shown in FIG. 1, the cooler 18 may be installed on the ceiling or the side of the storage 20 to provide natural convection or convection. In a countercurrent fashion, the temperature in the reservoir 20 is efficiently maintained constant.
본 고안의 실시예에 따른 상변화물질을 이용한 축냉식 냉동,냉장고는 야간에 심야전력을 이용하여 구동되는 압축기(12)에 의하여 작동되는 냉동기에 의하여 냉각기(18)내에 봉입된 상변화물질(19)을 결빙함으로써 축냉작용을 하며, 주간에는 상변화물질(19)이 해빙되면서 저장고(20)내의 온도를 일정한 저온으로 유지한다.The cold storage and freezer using the phase change material according to the embodiment of the present invention is a phase change material (19) enclosed in the cooler (18) by a freezer operated by a compressor (12) driven by night power. The ice-cooling function by the ice is frozen, and during the day, the phase change material 19 is thawed and the temperature in the storage 20 is maintained at a constant low temperature.
이상 실시예를 들어 본 고안에 대해 설명하였으나, 본 고안은 상술한 실시예에 한정되는 것은 아니며, 본 고안의 기술사상 및 기술범위내에서 각종 변경 및 개량이 가능하다.Although the present invention has been described with reference to the above embodiments, the present invention is not limited to the above-described embodiments, and various modifications and improvements can be made within the spirit and scope of the present invention.
본 고안에 따른 상변화물질을 이용한 축냉식 냉동,냉장고는 심야전기를 사용하기 때문에 냉동기 작동 비용이 최소화되는 효과가 있으며, 상변화물질을 사용하여 간접적으로 저장고를 냉동,냉장하기 때문에 식품의 건조와 같이 식품에 미치는 부정적인 영향을 최소화하는 효과 및 냉각기를 제상할 필요성을 최소화하는 효과가 있어 식품보관에 필요한 저장고 내의 온도를 일정하게 유지하는 효과가 현저하다.The cold storage and freezer using the phase change material according to the present invention has the effect of minimizing the operation cost of the freezer because it uses the midnight electricity, and indirectly freezing and refrigerating the store using the phase change material, such as drying food. The effect of minimizing the negative effects on food and minimizing the need to defrost the cooler is significant in keeping the temperature in the reservoir required for food storage constant.
