To achieve concentrated supply of cold, China -French Ecological City has a "super central air conditioner"

The Yangtze River Daily Da Wuhan Client August 7th. After the centrifugal machine and the air source heat pump, the tap water can be cooled to 5 ° C. When the "Cool Water Legion" starts from the energy station, and follows the pipeline of the underground comprehensive corridor of the Sino -French ecological city. After the heat exchange station, the cooling air in the cool water is sent to the user's home through the fan coil equipment. The "Cold Water Legion" that completes the cooling mission will return to the energy station, and then set off after circulating ...

By next summer, the concentrated supply of concentrated supply like concentrated heating will become a reality in the Sino -French Ecological City. On August 4, a reporter from the Yangtze River Daily came to the first large -scale regional distributed energy station in our city -China French Wuhan Ecological Demonstration City Energy Station in the start area of ​​the Wuhan Ecological Demonstration City. "Super Central Air Conditioning" is undergoing device debugging, and it will have operating conditions at the end of the year.

Wuhan's first large -scale energy station with cold supply

Along the newly -laid ecological city avenue, the reporter came to the energy station of the Sino -French Ecological City Start District. On the hot summer, workers are laying the roads in the stations to set up cable facilities.

When I walked into the energy station, I saw a thick pipe wrapped in the black insulation material extended from the outdoor into the room. Guo Feng, a minister of the project management of China -Law Investment Corporation, said that these pipelines have good thermal insulation effects. Even if they are transported to users' homes 1.5 kilometers away, the temperature difference can be controlled at 0.3 ° C.

Guo Feng introduced that the water temperature in summer should reduce the water temperature, mainly by a centrifugal refrigerator. He pointed to a half of the container -sized device to tell reporters that this centrifugal refrigerator uses the high -efficiency refrigeration equipment of the national standard first -level energy efficiency, refrigeration efficiency About two times the ordinary air conditioner, 380 tons of tap water can be cooled to 5 ° C per hour. There are 4 such equipment in the station.

"Concentrate to the cold -end -end loose device is mainly a fan coil equipment, that is, the central air -conditioning ending equipment commonly in large public places such as shopping malls." Guo Feng explained that the crew continues to circulate the air in the room , Blow the cooling wind to achieve the cooling effect. The cooling effect of the energy station is equivalent to ordinary air conditioners. Users can independently adjust the indoor temperature according to their own needs.

When the "Cold Water Legion" absorbs the heat and completes the cooling mission. At this time, the water temperature rises from the previous 5 ° C to about 13 ° C, and then reaches the energy station through the pipe network to recycle the cooling.

It is understood that the energy station can cover about 1.03 million square meters of buildings. In the future, users, hotels, office buildings, residential areas and other users in the western area of ​​China France Ecological City will be mainly served.

"Grab" energy in the air to achieve winter heating

Outside the energy station station, eight air -contained air -source heat pumps are neatly arranged and are about to debug.

Guo Feng introduced that the air source heat pump is the core equipment for winter heating in energy station. The water supply temperature of the energy station in winter is 50 ° C to 55 ° C. As the protagonist, the air source heat pump will collect the low -quality calories contained in the "capture" air for heating and heating heat water. More than 60%. At the same time, the energy station also compacted through the three -connected supply system and the gas boiler system through the gas cooling and heat power triple supply system and the gas boiler system to achieve stable heating.

"The heating end system can choose a fan coil, or to choose floor heating or radiator." Guo Feng said that concentrated supply of cold heating will adopt the most advanced technology of China and France to optimize the management technology of energy, and the roof of the energy station will be laid. There is a photovoltaic power generation system to maximize the utilization of energy.

In the interview, the reporter learned that in May this year, the first intelligent underground comprehensive pipe corridor in Caidian District -a comprehensive pipe corridor of the Sino -French Wuhan Ecological Demonstration City, which is about 8.1 kilometers long and an average depth of 7.5 meters, was officially put into operation, and thermal pipeline was the leader as the leader The pipeline is officially entered. Concentrated cooling and heating can share this thermal pipeline system, saving repeated construction costs and space resources, and realizing the switching of "refrigeration" and "heating" tube.

It is reported that as the sewage pumping station next to energy stations is put into use, the second phase of the energy station will introduce sewage source heat pumps.

The relevant person in charge of the Sino -French Ecological Urban Management Committee stated that the Sino -French Ecological Demonstration City, as a pilot demonstration project of nearly zero carbon town in Hubei Province, is constantly establishing a low -carbon transportation system in addition to the use of renewable energy sources, widely promoting green building applications, and concentration Develop high -tech research and development, innovation and other industries.
