Description

자가발전 냉장냉동탑차{Cargo box or container with self electricity generate refrigeration system }BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator,

본 발명은 차량의 냉장,냉동 적재함이나 냉장, 냉동 컨테이너 박스에 관한 것으로, 차량의 엔진이나 차량의 배터리 동력 없이도 냉장, 냉동 적재함이나 컨테이너 박스 내부를 냉장, 냉동시키기 위한 자가발전 냉장, 냉동시스템에 관한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator, a refrigerator, a refrigerator, and a freezer container box of a vehicle. More particularly, the present invention relates to a refrigerator, a refrigerator, will be.

일반적으로, 냉장, 냉동 적재함의 경우 차량 자체의 엔진을 사용하는데, 이 경우 엔진 기동부하가 증가하여 연료소모가 커지고, 엔진 정지시 냉동사이클도 정지하는 문제가 발생한다.
Generally, in the case of a refrigerator or a refrigerator, an engine of the vehicle itself is used. In this case, the engine starting load is increased, fuel consumption is increased, and the refrigeration cycle is also stopped when the engine is stopped.

또 다른 경우, 별도의 엔진을 통해 냉동사이클을 구성하는 서브엔진 형태를 사용하는데, 차량 엔진이 정지한 상황에서도 냉동사이클을 구동한다는 장점이 있는 반면, 냉방사이클 구성을 위한 별도 엔진설치로 설치공간이 많이 필요하고, 설치비용도 증대하는 문제가 발생하며, 냉방사이클 구동 엔진 자체의 열로 냉동효율이 저하되는 문제도 있다.
In another case, a sub engine type is used to constitute a refrigeration cycle through a separate engine. However, there is an advantage in that the refrigeration cycle is driven even when the vehicle engine is stopped. On the other hand, There is a problem that a large amount of refrigerant is required and the installation cost is also increased, and there is also a problem that the refrigerating efficiency is lowered by the heat of the cooling cycle driving engine itself.

그 밖에 차량용 에어콘시스템 압축기를 차량엔진이 아닌, 별도의 BLDC모터로 구동하는 방법을 제시하나, 냉동차량에는 적용이 불가하고, 차량용 배터리로 냉동시스템을 구동하는 방법의 경우, 역시 냉동차량에는 적용이 불가하다.
In addition, a method of driving a compressor for a vehicle air conditioner system using a separate BLDC motor instead of a vehicle engine is proposed. However, this method can not be applied to a refrigerated vehicle. In the case of driving a refrigeration system using a vehicle battery, It is impossible.

특허 제10-2014-0021286B1(냉동차량용 냉동시스템)의 경우, 차량엔진의 발전기에 의해 냉동 적재함 냉동시스템 가동용 배터리를 충전하는 방법을 공시하고 있다. 이렇게 하면 상기 문제들이 해결가능 하나 배터리 용량이 커져야 하고, 여전히 차량의 엔진출력에 의존하고 있다.
In the case of Patent No. 10-2014-0021286B1 (refrigeration system refrigeration system), a method of charging a battery for operating a refrigeration system refrigeration system by a generator of a vehicle engine is disclosed. In this way, the above problems can be solved, but the battery capacity must be increased and still depend on the engine output of the vehicle.

종래특허 제 10-2011-1015623A호(브라인순환 PCM축냉시스템) 의 경우, PCM잠열 축열재를 축냉모듈에 저장한 후, 병렬방식으로 여러 개로 축냉판을 형성하여 적재함 천정에 부착하여 차량 하부에 설치된 냉동시스템을 심야전력을 사용 약8시간 가동하여 PCM을 동결시킨 후, 자연 대류 방식으로 방냉시키는 방법을 사용하는 데 발생하는 문제인 PCM축냉판 결로현상과 운행중 축냉판 무게에 따른 적재함 무게중심이 상부로 이동하여 굽은길에서의 전복 위험성의 문제점을 해결 하기 위한 방법으로 축냉판에서 방출되는 냉기 사용방식을 축냉조 내부에서 외부공기가 순환, 배출할 수 있도록 공기순환 열교환기를 설치하고, 축냉조 열손실 방지를 위해, 이중구조 몸체를 구성, 몸체 내부를 진공 처리한 후 비활성 가스인 아르곤 가스를 충전하여 단열하는 기술을 제안하고 있다.
In the case of the conventional Patent No. 10-2011-1015623A (brine circulating PCM cold storage system), after the PCM latent heat storage material is stored in the hot-water storage module, a plurality of cold storage plates are formed in parallel and attached to the loading ceiling, PCM cold plate condensation phenomenon which is a problem that is caused by using freezing system by using nighttime power for about 8 hours to freeze PCM and cooling by natural convection, As a method for solving the problem of rollover on the curved road, an air circulation heat exchanger is installed so that external air can be circulated and discharged from the interior of the axial cold storage by using the cold air discharge method from the axial cold plate, , We proposed a technology to construct a double structure body, vacuum-process the inside of the body, and insulate it with argon gas, which is an inert gas. And there.

본 발명은 차량의 엔진출력에 의존하지 않는 냉장, 냉동시스템을 제공함에 목적이 있다.
An object of the present invention is to provide a refrigerating and freezing system that does not depend on the engine output of a vehicle.

또한 외부 동력을 거의 사용하지 않아 별도의 에너지 비용 지출이 없을 뿐 아니라 차량 운행 조건에 아무 영향을 받지 않고, 냉장, 냉동적재함 내부 온도를 아주 정밀하게 제어 함으로서 적재되는 화물에 최적화된 온도로 배송할 수 있는 냉장, 냉동시스템을 제공함에 목적이 있다.
In addition, there is no extra expenditure of energy due to not using external power, and it is possible to deliver the optimized temperature for cargo by controlling the internal temperature of the refrigeration and freezer freely without being affected by the conditions of the vehicle. Refrigeration, and refrigeration systems.

일반적인 냉장, 냉동시스템은 압축기(압축), 외기응축기(응축), 팽창밸브(팽창), 외기증발기(증발)사이클로 구성된 역랭킨사이클로 구성되어 있다.
A typical refrigerating and freezing system consists of a reverse Rankine cycle consisting of a compressor (compression), an outdoor condenser (condensation), an expansion valve (expansion), and an outdoor evaporator (evaporation) cycle.

이 경우, 외기증발기는 냉장, 냉동적재함 내부에 설치되어 상기 사이클의 작동열매체가 적재함 내부 공기로 부터 열을 흡수하여 증발되어 압축기에 의해 고온 고압 기체상태로 되어 외기응축기를 통해 응축열을 외기로 방출하게 된다.
In this case, the outside-air evaporator is installed inside the refrigerating and freezing compartment, and the working heat medium of the cycle absorbs heat from the air inside the loading compartment and is evaporated and is discharged into the high-temperature high-pressure gas state by the compressor to discharge the condensation heat to the outside air through the outside- do.

응축열을 방출한 작동 열매체는 고압 액체상태로 상변화 되어 팽창밸브를 통과하면서 저압액체로 되어 다시 적재함 내부 외기증발기를 통해 적재함 내부 열원을 흡수 증발 함으로서 냉장, 냉동사이클을 형성한다.
The operation heat medium discharging the condensation heat is phase-changed into the high-pressure liquid state, passes through the expansion valve, becomes the low-pressure liquid, and re-evaporates the heat source inside the loading chamber through the inside air evaporator.

그러나, 압축사이클을 위해서는 압축기가 사용되고, 압축기를 구동하는데 많은 구동전력이 필요로 하고, 적재함 내부 온도가 내려가면서 작동 열매체가 흡수할 열량이 작아져 전체 냉장, 냉동시스템 효율도 낮아지는 문제가 발생한다.
However, since a compressor is used for the compression cycle, a large amount of driving power is required to drive the compressor, and as the temperature inside the loading chamber is lowered, the amount of heat absorbed by the working heating medium is reduced and the efficiency of the entire refrigeration and refrigeration system is lowered .

본 발명에서는 상기 역랭킨사이클과 비등점이 낮은 작동 열매체를 사용하는 유기랭킨사이클을 결합하여, 역랭킨사이클 에서 공급한 열량을 유기랭킨사이클에 공급하여 전력을 생산하고, 생산된 전력을 전체 냉장,냉동시스템 소요동력으로 다시 제공 함으로서 에너지 소비가 거의 없는 자가발전 냉장, 냉동시스템을 제공할 수 있다.
In the present invention, an organic Rankine cycle using an inverse Rankine cycle and an operation heating medium having a low boiling point is combined to supply electric power to the organic Rankine cycle in a reverse Rankine cycle to generate electric power, The system can be supplied as a power source to provide self-generated refrigeration and refrigeration systems with little energy consumption.

또한, 적재함 내부 온도가 설정온도로 떨어지면서 작아지는 흡수열량으로 인해 발생하는 냉장, 냉동효율 문제를 해결하고 유기랭킨사이클에서 계속 전력을 생산할 수 있도록, 외기증발기를 증발사이클에 추가하여 외기공기로 부터 추가 열량을 흡수하여 냉장, 냉동효율 저하 없이, 자가 발전을 통해 냉장, 냉동시스템에 소요동력으로 제공 함으로서, 고효율 냉장 ,냉동시스템을 제공할 수 있다.
In addition, to solve the refrigeration and refrigeration efficiency problems caused by the reduced calorific value of the internal temperature of the loading tray, it is necessary to add an outside air evaporator to the evaporation cycle so as to continuously generate electricity in the organic Rankine cycle. It is possible to provide a highly efficient refrigeration and refrigeration system by absorbing the additional heat and providing it as a power source for the refrigeration and refrigeration system through self-power generation without lowering refrigeration and refrigeration efficiency.

또한, 아주 작은 온도차 까지 제어가 가능하여, 적재화물의 특성에 맞추어 적재함 내부 온도를 맞추어 줄 수 있다.
Also, it is possible to control to a very small temperature difference, and it is possible to adjust the internal temperature of the loading box to suit the characteristics of the load cargo.

수산물이나 축산물, 농산물과 같이 장시간에 걸쳐 배송하기 어려운 화물을 차량이나 컨테이너 박스에 자가발전 냉장, 냉동시스템을 설치 함으로서 문제를 해결할 수 있고, 공기열과 적재함 내부 열원을 흡수하여 발전을 하기 때문에, 추가의 연료비가 발생하지 않아 화물 운송비용을 크게 낮출 수 있다.
Since the self-generated refrigeration and refrigeration system is installed in a vehicle or container box, it is possible to solve the problem by absorbing the heat of the air and the internal heat source of the cargo box, The cost of freight transportation can be greatly reduced because no fuel cost is generated.

또한, 화물 운송기간이 길어도 신선한 상태로 적재된 화물을 보관 운송할 수 있어 농수산, 축산물 유통에 많은 영향을 끼칠 수 있다.
In addition, even if the period of cargo transportation is long, it is possible to store and transport the cargo loaded in a fresh state, which can greatly affect the distribution of agricultural, livestock, and livestock products.

One or more of the dual pipe outdoor vapor evaporators 124_1 to 124_n connected in parallel in the heat acquisition cycle are installed in the inside of the refrigerator and freezer compartment 708 and are controlled by the solenoid valves 125_1a to 125_na / 125_1b to 125_nb You can adjust the number of double pipe outdoor evaporator that is operated by.

이중관 외기증발기(124_1~124_n)는 열취득사이클 작동열매체를 위해 도관과 외기증발기에 발생하는 성애를 제거하기 위해 유기랭킨사이클 작동열매체의 응축열을 공급하는 도관으로 이중 구성된 열교환기 이다.
The dual tube ambient vaporizer (124_1 to 124_n) is a dual heat exchanger for supplying the heat of condensation of the organic Rankine cycle working heat medium to remove the malaise generated in the conduit and the outside air evaporator for the heat recovery cycle working heat medium.

성애를 제거하기 위한 제상운전 을 위해서 전자밸브(106_1a~106_na/106_1b~106_nb) 제어에 의해 유기랭킨사이클 작동열매체가 통과할 수 있게 함으로서, 유기랭킨사이클 작동열매체의 응축열을 전달하여 성애를 제거하고 잉여열원은 다시 이중관 외기증발기 작동열매체가 증발하면서 흡수된다.

적재함 내부 온도가 설정온도에 다가 갈수록, 이중관 외기증발기에서 작동열매체가 흡수할 열량이 작아져, 전체 시스템 효율저하를 가져올 수 있는데, 본 발명에서는 유기랭킨사이클 작동열매체의 응축열을 열교환기(103)을 통해 역랭킨사이클 작동열매체에 전달하고, 외기증발기(126)를 통해 외기공기로 부터, 추가 열원을 흡수하여 열교환기(105)를 통해 응축열을 유기랭킨사이클에 공급하여 전력을 생산할 수 있다.
As the internal temperature of the loader approaches the set temperature, the amount of heat absorbed by the working heat medium in the dual pipe external air evaporator becomes smaller, which may lead to a decrease in the overall system efficiency.
