Abstract

The invention discloses a rapid and accurate temperature control method for a medical refrigeration box and the medical refrigeration box. The method comprises the steps that the in-box actual temperature of the medical refrigeration box is obtained, and the preset temperature difference between an in-box target temperature and the in-box actual temperature is calculated; if the temperature difference is larger than a condition threshold value delta M, a proportionality coefficient KP (C) is calculated according to the environment temperature C of the environment where the medical refrigeration box is located, and the working frequency F of an inverter compressor is obtained through P control; otherwise, a proportionality coefficient KP (S) and an integral coefficient KI (S) are calculated according to the preset in-box target temperature S, the working frequency F of the inverter compressor is obtained through PI control, the rotating speed of the inverter compressor is controlled according to the working frequency F, and one-time temperature control over the medical refrigeration box is achieved. According to the rapid and accurate temperature control method for the medical refrigeration box and the medical refrigeration box, rapid and accurate temperature control is achieved.

Description

technical field [0001] The application belongs to the technical field of medical refrigeration, and in particular relates to a rapid and precise temperature control method for a medical refrigerator and a medical refrigerator. Background technique [0002] With the rapid development of the medical refrigeration industry, there is an increasing demand for medical equipment in major medical institutions, research institutes, and disease control centers. At the same time, higher requirements are placed on the performance of medical equipment. Some special products, such as sensitive medicines, vaccines, and blood, require high precision and stability of refrigeration temperature control during transportation and storage. When the refrigeration temperature is exceeded, the original effect cannot be exerted, and it may even lead to failure ; For example: vaccines must be stored in the dark at 2-8°C; whole blood and red blood cells must be stored at 4±2°C in order to keep the acti...
