The water of the Yangtze River becomes "air conditioner", and Wuhan was born in the country's first river water source for low -carbon schools

Wuhan Evening News September 13 (Reporter Tan Zuxian) No air -conditioning is used, without cooling towers, and you can enjoy the "green" cool wind from the Yangtze River with just twisting the switch, which is very comfortable. On September 13th, a reporter from the Changjiang Daily saw on the third primary school of Changchun Street, Jiang'an District that all the more than 14,000 square meters of campus had been installed with "Jiangshui Air Conditioning" provided by the Jiangsui Energy Station of Hankou Binjiang Business District. The school's teachers and students became the first batch of users in the province's first river water source energy station, and the school became the first low -carbon campus in the country to supply energy in the country.

The so-called "river water air conditioning" is actually the technology of the river water source heat pump technology. In simple terms, this technology is the characteristic of the water at the bottom of the Yangtze River higher than the room temperature and lower the temperature of the room. Source of hot and cold. In the summer, the water at the bottom of the river is extracted as a cold source, and through the water pump station, the heat pump unit, the pipeline network, and the heat exchanges room, the central air -conditioning system in the building absorbs part of the indoor heat to achieve the refrigeration effect. In winter, extract the water at the bottom of the river as a heat source, and transmits the energy to the room through the air -conditioning system to achieve the heating effect. Water resources will not be consumed during the operation of the entire "river air conditioner".

It is understood that compared with traditional air conditioners, "Jiangshui Air Conditioning" has outstanding advantages such as efficient, energy saving, low noise, and urban hot island effects. "Jiangshui Air Conditioning" only needs to run for 10 minutes, and the temperature in the classroom can be reduced from 30 ° C to 17.2 ° C. After 15 minutes, the room temperature drops to 14.3 ° C. According to estimates, compared to traditional air conditioners, 30%of energy can be saved as a whole.

In addition, the working principle of "Jiangshui Air Conditioning" is different from traditional air conditioners. It does not need to use the terminal to configure the refrigeration equipment, nor does it need to install an air -conditioning machine or cooling tower. This is not only more beautiful in appearance, but also eliminates the impact of air -conditioning noise and hot island effects on the urban environment.

"In actual use, the wind blew out of the" Jiangshui Air Conditioning "is more moist and softer." Wen Xiaoyong, the principal of the third primary school of Changchun Street, Jiang'an District, said: "Introduce the 'Jiangshui Air Conditioning' as a vivid case in classroom teaching to help students be more Understand green environmental protection technology directly and practice green and low -carbon life.
