Temperature controller plays an important role in the refrigeration cabinets

[2012-02-18]

Refrigeration as a science means using artificial method in a certain time period and space within a certain object or fluid cooling, make its temperature dropped to environmental temperature below, and keep the low temperature. Temperature controller plays an important role.

Here said the "cold" is relative to the environment concerned. Searing iron in the air, through radiation and heat transfer, gradually to flow to the environment cooled to environmental temperature. It is spontaneous, belongs to the natural cooling heat-transfer cooling, not refrigeration.

Refrigeration is removed from the object or fluid heat, and will be released into the environment medium heat, to generate below environment temperature process. Low temperature system freezers for plastic different profile and chemical building material sample low-temperature processing, temperature freezing equipment - low temperature refrigeration working principle: working principle, temperature sensors feel temperature signal input amplifier, through the simulation switch, A/D transformation input temperature control meter, by running PID program gives corresponding refrigeration parameters, control the refrigeration time, so as to achieve the purpose of temperature control, test can safe and reliable, so as to ensure the safe and reliable test. This device descriptor DB/T8848 standard requirements, which can realize real-time display, temperature control, measuring, alarm functions. Cryogenics equipment - low temperature refrigeration instrument main performance indexes: temperature control scope: - 20-0 ℃, temperature control precision: setting 1℃, LED display on temperature controller.
