Temperature control system and method for miniature constant-temperature box

Abstract

The invention relates to a constant-temperature storage device in examination and chemical analysis of biology and clinical medicine, and discloses a temperature control system and method for a miniature constant-temperature box. According to the temperature control system and method for the miniature constant-temperature box, the proportional-integral-differential algorithm is adopted for calculating the detected temperature in a constant-temperature box body, the detected environment temperature and a preset target temperature to determine heating or refrigerating and obtain the heating time or the refrigerating time. The portion, storing biological samples, in the constant-temperature box body is heated or refrigerated, so that the temperature in the constant-temperature box body is equal to the target temperature constantly. According to the temperature control system and method for the miniature constant-temperature box, the temperature in the constant-temperature box body can be automatically adjusted to reach the set target temperature, and the limitation of the environment temperature is avoided.

Description

technical field [0001] The invention relates to a constant temperature preservation device in biological and clinical medical examination and chemical analysis, in particular to a temperature control system and method for an intelligent biological vaccine sample constant temperature preservation box. Background technique [0002] Thermostats are widely used in the fields of pharmacy, seedling raising, and food preservation. At present, some medical thermostats are refrigerated by Freon and controlled by a thermostat. The equipment has a complex structure, a large mechanism, and high cost, especially when using a constant temperature space. Hour use is very inconvenient. Another part of the incubator used in the market and the industry is too large and can only be heated, and the cooling needs to rely on the external environment for heat diffusion, so the lower limit of cooling is the ambient temperature, which is completely unable to meet the requirements of high-end vaccine...

AI Technical Summary

Problems solved by technology

[0002] Thermostats are widely used in the fields of pharmacy, seedling cultivation, food preservation, etc. At present, some medical thermostats are refrigerated by freon and controlled by a thermostat. Hourly use is inconvenient

Another part of the incubator used in the market and the industry is too large and can only be heated, and the cooling needs to rely on the external environment for heat diffusion, so the lower limit of cooling is the ambient temperature, which is completely unable to meet the requirements of high-end vaccines and many biological samples. Requirements for temperatures even sub-zero

In addition, there are still many problems in the storage of high-end biological vaccines and samples, such as large box volume, high power consumption, unstable and uneven temperature inside the box, low cooling and heating efficiency, slow constant temperature process, etc.
