Description
본 고안은 냉동장치에 관한 것으로서, 더욱 상세하게는 식품을 냉동보관하는 냉동창고에 적용되는 냉동장치에 관한 것이다.The present invention relates to a refrigerating device, and more particularly to a refrigerating device applied to the freezer for freezing food storage.
일반적으로 냉동창고는 어류 또는 육류 등의 냉동식품을 보관하는 곳으로서, 저장물의 품질을 양호하게 유지하기 위해서는 적절한 온도를 유지하여야 한다. 이때 저장실의 온도는 영하의 온도를 유지하게 되는 것이 보통이다. 냉동창고용에 적용되는 냉동장치의 경우에는 대량의 저장물을 보관하게 되므로 상대적으로 대용량 즉, 비교적 넓은 공간을 고르게 냉동가능한 것이 필요하며, 아울러 저장온도를 설정된 온도범위 내에서 고르게 유지할 것을 요구하게 된다.In general, a frozen warehouse is a place for storing frozen food such as fish or meat, and in order to maintain good quality of the stock, it is required to maintain an appropriate temperature. At this time, the temperature of the storage room is usually to maintain the temperature below zero. In the case of a refrigeration apparatus applied to the freezer storage it is required to be able to freeze even a relatively large capacity, that is, a relatively large space evenly because it stores a large amount of storage, and also requires to maintain the storage temperature evenly within the set temperature range. .
냉동장치는 잘 알려진 바와 같이 냉매를 소정의 경로 즉, 크게 압축,응축,팽창,증발을 순차적으로 순환시키는 과정에서 냉기를 발생시키는 이른바, 냉동사이클을 이용하는 것으로서, 위 순환과정을 간단하게 설명하면 크게, 냉매를 압축하여 고온고압의 액체상태로 토출하는 압축기와, 압축된 냉매를 외기와 열교환(열방출)하여 상온고압의 상태로 하는 응측유닛과, 응축된 냉매를 단열팽창시켜 저온저압의 상태의 기체상태로 상변화시키는 팽창밸브와, 저온저압의 기체상대 냉매를 외기와 열교환(열흡수)하여 상온저압의 상태에서 다시 상기 압축기로 송출하는 증발유닛으로 구성된다. 또한, 증발유닛을 거친 냉매는 냉매의 안정된 흐름을 제어하는 어큐물레이터를 통해 압축기로 공급된다.As is well known, a refrigerating device uses a so-called refrigeration cycle that generates cold air in a predetermined path, ie, a process of circulating compression, condensation, expansion, and evaporation in sequence, as described above. And a compressor for compressing the refrigerant and discharging it in a liquid state of high temperature and high pressure, a measurement unit for exchanging the compressed refrigerant with an outside air (heating) to a normal temperature and high pressure state, and thermally expanding the condensed refrigerant to a low temperature and low pressure state. An expansion valve for changing the phase of the gas into a gas state, and an evaporation unit for exchanging the low-temperature and low-pressure gas relative refrigerant with the outside air (heat absorption) and sending it back to the compressor in the low-temperature low-pressure state. In addition, the refrigerant passing through the evaporation unit is supplied to the compressor through an accumulator for controlling a stable flow of the refrigerant.
일반적인 냉동창고에 있어서는 상기 증발유닛은 저장실에 설치되고, 나머지 요소들은 조립체로 구성되어 저장실의 외부에서 별도로 설치되어 진다.In a typical freezer warehouse, the evaporation unit is installed in the storage compartment, and the remaining elements are composed of an assembly and are separately installed outside the storage compartment.
그러나, 종래의 냉동창고는 일반적인 냉동사이클을 그대로 사용하고 있으므로 저장실의 보관량 변화에 따른 효과적인 대처가 어렵다는 문제를 갖고 있다. 즉, 냉동사이클의 냉동성능은 압축기의 성능에 의해 결정되는 바, 종래의 냉동창고에 적용되는 냉동장치는 일정한 압축성능을 갖는 하나의 압축기에 의해 제어된다. 따라서, 저장실의 부하변동 즉, 저장량이 급격하게 증가할 경우 또는 고온의 저장물이 입고되었을 경우 등과 같이 급냉을 요할 때 효과적으로 대응할 수 없는 것은 물론 저장량이 적을 때에는 불필요한 냉동이 이루어지는 등 냉동효율이 떨어지는 문제를 갖고 있는 것이다.However, the conventional refrigeration warehouse has a problem that it is difficult to effectively cope with the change in the storage volume of the storage compartment because it uses a common refrigeration cycle as it is. That is, the refrigeration performance of the refrigeration cycle is determined by the performance of the compressor, the refrigeration apparatus applied to the conventional refrigeration warehouse is controlled by one compressor having a constant compression performance. Therefore, the load efficiency of the storage compartment, that is, when the storage volume is rapidly increased or when a high temperature storage item is received, such as when the need for quenching can not be effectively responded to the problem of freezing efficiency, such as unnecessary refrigeration when the storage capacity is low, the problem is inferior To have.
이에 본 고안은 상기와 같은 점들을 감안하여 안출된 것으로서, 그 목적은 저장량의 변화 또는 상태에 따라 냉동성능을 효과적으로 제어하여 냉동효율을 향상시킬 수 있는 창고의 냉동장치를 제공함에 있다.Accordingly, the present invention has been made in view of the above points, and an object thereof is to provide a freezing device of a warehouse that can effectively control the freezing performance according to the change or state of the storage amount to improve the freezing efficiency.

Can be achieved by
이하, 본 고안의 바람직한 실시 예를 첨부한 도면을 참고하여 구체적으로 설명하면 다음과 같다. 도 1에는 본 고안에 따른 창고의 냉동장치의 구성이 블록도로 도시되어 있다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail. 1 is a block diagram showing the configuration of a refrigeration apparatus of a warehouse according to the present invention.
이에 따르면, 본 고안은 예정된 경로를 따라 순환하는 냉매를 완충적으로 수용하여 냉매의 안정적인 흐름을 유도하는 어큐물레이터(10)가 제공된다. 어큐물레이터(10)에는 적어도 둘 이상의 압축기(20)가 연결되어있는데, 이들 압축기(20)는 각각 어큐물레이터(10)에 저장된 냉매를 독립적으로 공급받아 압축하여 냉매를 고온 고압의 상태로 변화시킨다. 각각의 압축기(20)에서 압축된 냉매는 각각의 압축기(20)에 연결된 분리기(22)들을 통해 기포, 수분 등의 불순물이 분리된 상태에서 응축유닛(30)으로 전달된다. 응축유닛(30)에는 외기와 열교환(열방출)을 이루어 고온고압의 냉매를 상온고압의 상태로 변화시키게 된다.Accordingly, the present invention provides an accumulator 10 for buffering the refrigerant circulating along a predetermined path to induce a stable flow of the refrigerant. At least two compressors 20 are connected to the accumulator 10, and each of the compressors 20 is independently supplied with a refrigerant stored in the accumulator 10 and compressed to change the refrigerant into a state of high temperature and high pressure. Let's do it. The refrigerant compressed by each compressor 20 is transferred to the condensation unit 30 in a state where impurities such as bubbles and moisture are separated through the separators 22 connected to each compressor 20. The condensation unit 30 performs heat exchange (heat release) with the outside air to change the high temperature and high pressure refrigerant into a state of high temperature and high pressure.
그리고, 응축유닛에서 냉각된 냉매는 팽창밸브(40)를 통과하는 과정에서 단열팽창을 이루며 저온저압의 기체상태로 상변화하여 증발유닛(50)으로 이동한다.In addition, the refrigerant cooled in the condensation unit forms an adiabatic expansion in the course of passing through the expansion valve 40 and changes to a gas state at low temperature and low pressure to move to the evaporation unit 50.
증발유닛(50)은 저장물을 보관하게 되는 저장실(60)내에 설치되는 것으로, 저장실내의 공기와 열교환(열흡수)을 이루며 저장실내로 냉기를 공급하게 된다. 이어서, 증발유닛(50)을 통과한 냉매는 상온저압의 상태로 되어 다시 상기 어큐물레이터(10)로 회류하게 된다.The evaporation unit 50 is installed in the storage chamber 60 that stores the storage, and forms heat exchange (heat absorption) with air in the storage chamber and supplies cold air into the storage chamber. Subsequently, the refrigerant passing through the evaporation unit 50 is in a state of low temperature at room temperature, and flows back to the accumulator 10.
본 고안은 상기 저장실(60)에는 저장실(60)내의 온도를 측정하여 전기적 신호를 출력하는 온도감지센서(62) 및 이 온도감지센서(62)의 출력값을 인가받아 상기 각각의 압축기(20)들중 일부 또는 전부를 선택적으로 작동제어하는 제어부(70)를 포함한다.According to the present invention, the storage chamber 60 receives a temperature sensor 62 for measuring an temperature in the storage chamber 60 and outputs an electrical signal, and an output value of the temperature sensor 62 to receive the respective compressors 20. And a controller 70 for selectively controlling some or all of them.
이와 같은 구성을 갖는 본 고안은 온도감지센서(62)에서 저장실(60)내의 온도를 감지하여 제어부(70)로 인가하게 되고, 제어부(70)에서는 입력된 온도값을 설정되어 있는 저장된 온도값과 비교하여 압축기(20)를 제어하게 된다. 즉, 저장실(60)내의 온도가 기준값 이상이면, 전체의 압축기(20)를 가동하여 급속냉동을 실시하게 되고, 기준값 이하이면 선택된 압축기만을 계속적으로 작동시키고 나머지 압축기의 작동을 정지시키게 된다. 따라서, 저장실내의 내의 저장물을 가장 이상적인 온도조건에서 냉동 보관할 수 있게 된다.The present invention having such a configuration detects the temperature in the storage chamber 60 by the temperature sensor 62 and applies it to the controller 70, and the controller 70 stores the input temperature value and the stored temperature value. In comparison, the compressor 20 is controlled. That is, when the temperature in the storage chamber 60 is equal to or higher than the reference value, the entire compressor 20 is operated to perform rapid freezing. When the temperature is lower than the reference value, only the selected compressor is continuously operated and the remaining compressors are stopped. Therefore, the storage in the storage compartment can be stored frozen at the most ideal temperature conditions.
본 고안에 따르면, 상기 설정 값의 단계는 압축기의 수에 따라서 변동하게 된다. 즉, 압축기(20)가 4대일 경우를 예로들면, 제어부(70)에서는 일정한 차이를 갖는 3개의 설정온도를 기준으로 온도값이 상승함에 따라 각 단계별로 작동되는 압축기의 수를 늘려가는 형태로 제어를 실시하여 냉동효율을 높이게 되는 것이다.According to the present invention, the step of the set value is varied according to the number of compressors. That is, for example, when there are four compressors 20, the controller 70 controls the form of increasing the number of compressors operated in each stage as the temperature value increases based on three set temperatures having a predetermined difference. By doing it will increase the refrigeration efficiency.
이상에서 설명한 바와 같이 본 고안에 따른 창고의 냉동장치는 냉동사이클에 저장실의 온도변화에 따라 독립적 또는 동시에 작동제어되도록 함으로써, 저장실의 부하변동에 따른 적응력이 향상되므로 냉동성능 및 냉동효율을 향상시킬 수 있는 효과를 갖는 것이다.As described above, the refrigeration apparatus of the warehouse according to the present invention allows the refrigeration cycle to be controlled independently or simultaneously according to the temperature change of the storage compartment, thereby improving the adaptability according to the load variation of the storage compartment and thus improving the freezing performance and the freezing efficiency. It is to have an effect.
