Problems solved by technology

However, during the cooling process, the cooling capacity of the ice-filled row cannot be measured, or it is only a simple cooling effect. When charging the cold-filled incubator, it is impossible to detect whether the ice-filled row is completely frozen, resulting in The incubator is overcooled or insufficiently charged

Abstract

The invention discloses a metering and cold charging device of a cold charging constant-temperature box. The device is internally provided with a support, and a cold charging agent storage box, a refrigerating device and a controller are arranged in the support; and the refrigerating device comprises a heat exchanger, a liquid outlet pipeline and a liquid return pipeline are arranged on the cold charging agent storage box, external connectors are both arranged on the liquid outlet pipeline and the liquid return pipeline, a temperature sensor is arranged on the liquid return pipeline, and the temperature sensor is electrically connected with the controller. According to the device, the temperature sensor is arranged on the liquid return pipeline, the temperature change of the temperature sensor is monitored, so that whether the cold charging of a coolant of a heat preservation box is finished or not can be accurately judged.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a refrigeration insulation box and a fresh food cold chain. Background technique [0002] For items that need to be refrigerated for medicines and fresh food, using cold storage incubators is a common cold chain transportation solution. However, the current cold storage and incubator mostly adopts the method of moving ice row for cooling and heat preservation. Since the ice row needs to be pretreated in the cold storage before use, the cooling capacity is absorbed from the cold storage. After the cooling capacity of the ice row reaches the work requirement, Then put the ice row in the incubator, so the operation process of the cold storage incubator is more complicated, and the ice row is transported frequently, resulting in high labor costs, and when the cooling capacity of the cold storage ice row is released, the ice row needs to be replaced again , repacking, and at th...
