Embodiment

[0024] Embodiment: a kind of cooling water circulation method based on semiconductor refrigeration technology (see Figure 1-3 ), characterized in that it consists of the following steps:

[0025] (1) When the water is within the range from the initial temperature to the set temperature, use the circulation device to circulate the cooling water;

[0026] (2) When the temperature of the circulating cooling water is higher than the set temperature, the artificial refrigeration mode is started;

[0027] (3) When the water temperature returns to the set temperature after artificial refrigeration, continue to use the circulation device to circulate the cooling water.

[0028] The above-mentioned artificial refrigeration method that starts after the temperature of the circulating cooling water is higher than the set temperature can be the way of cooling the circulating water by using semiconductor refrigeration components or draining the circulating water that is higher than the se...

Abstract

The method includes following steps: (1) within temperature setup, using circulating device to use cooling water circularly; (2) starting up manual refrigeration mode when temperature is higher than set temperature; (3) using circulating device to use cooling water right along if temperature is returned back to temperature setup. The cooling water circulation apparatus is composed of semiconductor refrigeration module, circulating water system, intelligent control meter for detecting water temperature and DC power source for semiconductor. Advantages are: (1) quick lowering temperature of circulating cooling water to meet requirement of experiment; (2) remarkable water saving effect, saving 20-50 times of cooling water; (3) green technique, no leak of conventional refrigerant to destroy ozonosphere, saving energy also; (4) wide foreground.

Description

(1) Technical field: [0001] The invention belongs to the technical field of refrigeration, in particular to a cooling water circulation method and device based on semiconductor refrigeration technology. (two) background technology: [0002] The problem of water resources is one of the most prominent issues in the sustainable development of my country's social economy in the 21st century, and it is also a major issue of widespread concern in the world. It is facing an increasingly severe situation. How to find a reasonable, feasible and positive solution to the water resource problem from the lack of water resources that has plagued my country's social and economic development for a long time is an important issue that needs to be studied and solved urgently. Because of the limited water resources, it is necessary to use water scientifically and rationally, and all walks of life are exploring various water-saving measures. In industrial production, water-saving technologies ...
