In recent years, as the country attaches great importance to the development of the physical fitness of young people, swimming, as a sport that can not only maintain physical health, but also serves as a self-rescue skill, has gradually integrated into the assessment system for enrollment and graduation in primary and secondary schools.


Swimming exercise

The Education Bureau of Suzhou City issued a notice that the 2021 sports examination (swimming) for junior high school graduates in the urban area of Suzhou will officially start on September 24 and will end in early October, with October 9 being the postponement time. Boys can get a perfect score of 15 if they swim 50 meters in 60 seconds and girls in 70 seconds. Depending on the candidate's swimming speed, the score ranges from 7 to 15 points.
Zhejiang Zhuji Middle School sets an assessment upon graduation: starting from the 2020 freshmen, Zhuji Middle School requires every student to learn how to swim and conduct a unified assessment before graduation: boys can swim 50 meters and girls 30 meters to get a diploma. Swimming lessons are arranged from July to October every year, twice a week. Holidays are arranged separately.
In order to improve the swimming level of students, many schools have built indoor constant temperature swimming pools and selected high-quality constant temperature equipment to create a healthy and comfortable swimming training environment for students. Students do not need to face the wind and sun when swimming. Can do swimming exercises.


Young people are still developing and have higher environmental requirements. Swimming pools should be more cautious and professional when selecting equipment. If equipment is aging, equipment dehumidification, and purification effects are not up to standard, the equipment should be replaced in time. After many comparisons between Nanchong Qinglongshan Middle School and Shenzhen Pingshan Experimental Middle School, they abandoned the traditional operating mode of boiler heating and exhaust fan dehumidification, and chose to install AQUA three-in-one air source constant temperature dehumidification heat pump.


The school uses AQUA three-in-one dehumidification heat pump

The working principle of the constant temperature dehumidification heat pump is to recycle the evaporation heat loss on the surface of the pool water and transfer it to the pool water and air to make up for the heat loss of the pool water and air, while achieving air dehumidification and purification functions. It can greatly improve the environmental quality of the campus constant temperature swimming pool. Because of the energy-saving and environmental protection embodied in this product, it has become a solution to replace the traditional boiler + exhaust fan mode.

There are bacteria in the swimming pool air that can easily cause respiratory problems, and exposure to it for a long time will affect the health of young people. AQUA three-in-one air source constant temperature dehumidification heat pump adopts plasma sterilization and purification technology to generate a large amount of active hydroxide ions, active plasma sterilization, and precise air purification. Parents do not have to worry about the hygiene of the swimming pool.
According to the person in charge of the AQUA air source swimming pool heat pump, the swimming pool environment itself is a systemic problem, so a systematic solution is needed. For teenagers, the quality of the swimming pool environment is very important. Therefore, schools should choose high-quality swimming pool equipment to ensure the health of students .
