Method for establishing temperature curve, refrigerant proportioning method and related device

Abstract

The invention discloses a method for establishing a temperature curve, a refrigerant proportioning method and a related device. The method for establishing the temperature curve comprises the following steps: determining the temperature level of each region at a corresponding time according to the temperature value of at least one natural year in each region within the transportation range; determining a temperature class of a place of origin and a temperature class of a destination according to the conditions in which the conveyance is transported and the temperature class of each area at a corresponding time; a temperature profile characterizing a temperature distribution of the transport object during transport is determined based on a temperature level of the origin, a temperature level of the destination, and a predetermined transport path and path aging of the transport object. The temperature profile is determined based on the temperature level of the destination, and a predetermined transport path and path aging of the transport object. According to the technical proposal of the embodiment of the present application, the non-professional person can also quickly and accurately realize the refrigerant mixture ratio of the transport object according to the temperature curve of the transport object, thereby maximizing the mixture ratio efficiency and accuracy, and reducingthe transport risk.

Description

Technical field [0001] The present disclosure relates to the technical field of cold preservation and transportation, and in particular to a method for establishing a temperature curve, a method for proportioning refrigerants, and related devices. Background technique [0002] Because pharmaceutical products have strict requirements on temperature, most of them are transported in the cold chain with thermal insulation packaging. Insulation packaging relies on the cold and heat exchange between refrigerant (such as cold storage agent) and the outside to achieve temperature protection of the consignment, so the ratio of cold storage agent will change according to the external climate environment. When the operation of thermal insulation packaging is circulating, it needs to face the environmental and climate changes across the country. Therefore, during the research and development stage of thermal insulation packaging, a large number of shipping experiments are required to test t...

Problems solved by technology

However, based on China's wide geographical range and obvious climate change characteristics, everyone's sensitivity and expertise to data are inconsistent, and they are easily affected by human factors, resulting in a very long test process.

[0003] If the thermal insulation packaging is carried out according to human experience, it is easy to cause differences in the ratio of the cooling agent, resulting in differences in the insulation effect. If the ratio exceeds the required value, it will cause waste. If the ratio does not meet the required value, it may cause the risk of cargo damage.

[0004] It can be seen that the current method of refrigerant ratio relying on manual experience has the problems of low ratio efficiency and low ratio accuracy, and non-professionals cannot directly ratio
