Method and device for determining cold charging capacity in unit time and computer equipment

Abstract

The invention discloses a method and device for determining cold charging capacity in unit time and computer equipment. The method for determining the cold charging capacity in unit time comprises the steps of controlling a compressor to conduct refrigeration, and after refrigeration is conducted for preset duration, obtaining cold charging capacity corresponding to the preset duration; obtaining temperature difference value between an inlet and an outlet of a cold charging pipe in a cold charging process; and determining the cold charging capacity in unit time according to the cold charging capacity, the temperature difference value between the inlet and the outlet of the cold charging pipe and the preset duration. According to the method and device for determining the cold charging capacity in unit time and the computer equipment, the compressor is controlled to conduct refrigeration, the cold charging capacity corresponding to the preset duration is obtained after the refrigeration is conducted for the preset duration, and then the temperature difference value of the inlet and the outlet of the cold charging pipe in the cold charging process is obtained; and according to the cold charging capacity, the temperature difference value between the inlet and the outlet of the cold charging pipe and the preset duration, the cold charging capacity in unit time is determined, the cold charging capacity can be effectively and accurately quantified, and cold charging intelligent control is achieved.

Description

technical field [0001] The invention relates to the field of cold chain technology, in particular to a method, device and computer equipment for determining the cooling capacity per unit time. Background technique [0002] Cold chain container (cold storage box) is a kind of thermal insulation transportation equipment, which is used to transport temperature-sensitive goods such as fresh food, fruits and vegetables, and pharmaceuticals. By installing a cold storage device (such as a cold storage plate) that can release cold energy in the box, the product can be kept within a certain temperature range during transportation, and the quality of the goods can be guaranteed without changing the ambient temperature and humidity. In essence, the cold storage material in the cold storage equipment exchanges heat with the storage space through the energy change caused by the material phase change process, thereby regulating the temperature. After the cold storage material is used for...

Problems solved by technology

However, after charging for a certain period of time, it is not known exactly how much cooling capacity has been charged, so it cannot be accurately quantified, and it is not smart enough

It may happen that the cooling time is too long, and the cooling capacity of the cold storage material has already been filled, resulting in waste of resources; or the cooling time is too short, and the cooling capacity of the cold storage material has not been fully charged, which affects the insulation effect
