On some sites, fans are typically used to cool the work environment, but the fans have limited effect and can only generate air flow, but cannot lower the air flow temperature. Some water air conditioners are used for refrigeration at present, so that the working environment is improved. Most of the water air conditioners adopt a fan to blow air to a water tank to realize air refrigeration. For controlling and adjusting the temperature of circulating water of air-cooled equipment, the cold water is required to be primarily mixed through the water mixing tank, and for reducing the volume of the water mixing tank, the aim of rapid and uniform mixing is achieved at the same time, and the aim of rapid and uniform mixing of the cold water is achieved in the existing water mixing tank through the mode of additionally arranging an impeller for stirring. In practice vacuum is a spatial state in which no substance is present, a physical phenomenon. For refrigeration equipment, vacuumizing is an essential and important process before producing, installing and maintaining the refrigerant, and can suck out air in the refrigeration equipment and pipelines, and the air contains a large amount of dust and other impurities, so that the air can cause harm to the operation of the refrigeration equipment.
