The most significant drawback is that there is no uniform airflow in conventional refrigerated containers, resulting in temperature differences
[0004] Moreover, conventional refrigerated containers of the type known in the art have associated with them relatively high design and manufacturing costs, thus making manufacturers inclined to adopt designs that are not competitive for the purpose they are intended to serve
Therefore, those complex, unresolved and expensive design parameters of cold storage equipment lead to a loss of efficiency and thus a great loss to the industry and the economy as a whole

example 1
[0048] Example 1: Testing the performance of a cold storage system with perishable goods
[0049] Testing of the performance of the cold storage system was done by placing sensors at various locations inside the container. The specific location for placing the sensor is as follows:
[0057] - the exterior of the container to determine the ambient temperature
[0058] In order to ensure that the industry standards related to perishable cold chain are reliable, industry standards and meet industry compliance (industry compliance), the test is conducted by the staff of the Okinawa government.
[0059] Temperature-dependent data is measured at different locations at different temperatures. Then, use the collec...

[0061] Example 2: Testing the performance of a cold storage system by measuring temperature
[0062] Testing of the performance of the cold storage system was done by placing sensors at various locations inside the container. The specific location for placing the sensor is as follows:
[0063] - front top, front middle and front lower,
[0064] - middle top, center and middle lower,
[0065] - rear top, rear middle and rear lower,
[0066] - the exterior of the container
[0067] Temperature-dependent data is measured at different locations at different temperatures. Then, use the collected data to draw a graph with time on the X-axis and temperature on the Y-axis. The chart is in Figure 5 presented in .
[0068] It was found that, at all locations in the container, the temperature inside the container remained constant for more than one hundred and thirty hours.

[0069] Example 3: Testing the performance of the cold storage system in winter
[0070] Testing of the performance of the cold storage system was done in winter by placing sensors at various locations inside and outside the container. The specific location for placing the sensor is as follows:
[0071] - When tested in winter, it was found that a constant temperature was maintained at all locations of the container. Second, we also found that once the ambient temperature is lower, the support time is longer than in summer, which is attributed to the high ambient temperature in summer. In addition, even if the ambient temperature fluctuates, the internal temperature remains constant, with little influence from ambient temperature fluctuations. This is a good indication that ambient temperature fluctuations will have no effect on product temperature. In general, conventional refrigerated containers cannot maintain a constant temperature at all locations in the container. Eve...

Abstract
The present invention relates to a system for maintaining the temperature in cold storage equipment. The system comprises a refrigerating temperature Uniformly placed on top of the cold storage equipment a plurality of coolant layer: each coolant layer comprises a plurality of rows and columns of stacked coolant plate; a compressor airflow and the airflow generated in the cold accumulation device from top to bottom in the annular mode cycle; whereby the cold accumulation device is maintained at a temperature with the range of -25 DEG C to +25 DEG C; a plurality of coolant layer is placed adjacent to the compressor. In order to effectively recycle gas stream; a coolant container frame, to uniformly adjust a plurality of coolant layer in the plurality of coolant plate, and allowing the cold accumulation device from top to bottom in the effective airflow, a cold accumulation device base body is provided with a hole which is used for pumping the air by cycling the compressor; thereby improving the cold accumulation device the circulation of airflow, and a cold storage device is isolated to increase thermal insulation coefficient; so that the cold storage device, thereby to maintain the desired temperature of chilled coolant layer.
Description
technical field [0001] The present invention mainly relates to the field of refrigerated containers, in particular, to a system for maintaining chilled-frozen and constant temperature in cold storage equipment during cold chain transportation. Background technique [0002] Refrigerated containers and / or cold storage devices are widely used for various industrial and consumer purposes, ie to transport goods over long geographical distances. In today's rapidly growing world, refrigerated containers are used in almost every area of life and vary by industry. The continuous, long-term operation of refrigerated containers requires a lot of work and cooling efficiency, so it has high requirements for power generation and produces a huge amount of CO2 emissions. [0003] In addition, serious design difficulties are also encountered in the design and manufacture of cold storage equipment (cold storage) required to cater to the different needs of different industries. The design ...
