High-precision temperature control box precise temperature control method

Abstract

The invention relates to a high-precision temperature control box precise temperature control method. The method comprises the following steps of: S1, setting a temperature control box; S2, setting a temperature sensor; S3, setting a heat exchanger; S4, setting a temperature control set value; and S5, setting a control mode. According to the invention, a constant temperature box is set to a double-layer structure, a gradient temperature control method is adopted, and a temperature control box inner container is used for setting the temperature control target value; a middle interlayer is a temperature adjusting area, and with the inner container set temperature and an environment temperature as positive values, fine tuning is carried out on the temperature set value of the adjusting area, so that the precision of temperature control is improved.

[0002] In the fields of scientific experiments, medical tests, chemical analysis, food industry components and other laboratory fields, a special environmental experimental equipment with constant temperature - incubator, is widely used, and the experimental samples are placed in the space in the incubator. In the environment, through the specified time, the required sample index parameters and various data can be obtained after testing and testing, and then the physical and chemical properties of the sample and the combination of various components can be analyzed. With the advancement of science and technology and the change of relevant standards , the requirements for the accuracy of the detection parameters are getting higher and higher, and the environmental conditions of the samples are also becoming more and more strict. At present, the incubator used in the laboratory has a backward adjustment and control method, which can no longer meet the needs of the measurement and detection work. In the experiment The resulting data parameters are not repeatable
