Water triple-point bottle automatic freezing and storage device and method

Abstract

The invention provides a water triple-point automatic freezing and storage device, which comprises a refrigeration constant temperature tank and a compressor refrigeration machine unit, wherein liquid media is contained in the refrigeration constant temperature tank, the refrigeration constant-temperature tank comprises a mixing region and a work region, the compressor refrigeration machine unit refrigerates the liquid media, and a water triple-point bottle is arranged in the work region of the refrigeration constant-temperature tank. The invention also provides a water triple-point automatic freezing and storage method. The method and the device provided by the invention realize the complete automatic freezing and storage of the water triple-point bottle. The defects that during the conventional manual freezing, the bottle can be easily damaged, and labor and time are wasted are overcome. The work efficiency is greatly improved. A compressor refrigeration technology is adopted, and the slow temperature reduction freezing is realized, so the ice lattice distribution in the triple-point bottle is uniform, supercooling is avoided, and use is realized after the freezing. Instant use after the freezing can be realized, and time and labor are saved.

Description

technical field [0001] The invention relates to a device for automatically freezing and preserving a triple point bottle of water, and a method for automatically freezing and preserving the triple point bottle of water. Background technique [0002] The triple point of water is the fixed point of thermodynamic temperature, which is reproduced by the triple point bottle of water made by a special process. Usually, the interior of the water triple point bottle is in a two-phase state of pure water and water vapor. In order to realize the coexistence of the three phases, it is necessary to freeze the triple point bottle to freeze the water, so as to achieve a three-phase coexistence state of ice, water and water vapor. Theoretically, the physical quantity temperature that characterizes the coexistence of three phases is unique, and is assigned a value of 0.01°C. [0003] Usually, there are two traditional manual methods for freezing water triple point bottles: 1) Liquid nitrog...
