Phase change energy storage air handling unit is the latest patented product specially developed by Changsha Mairong High-tech Co., Ltd. and Hunan University for communication base stations. At present, it has obtained many national patents and belongs to the key products of Changsha Science and Technology Plan. The unit declared the National Torch Plan and the National Twelfth Five-Year Plan for Science and Technology, and passed the inspection by the technical supervision department of Hunan Province and the third-party authority. At present, the unit has achieved the expected energy-saving effect through field pilot test, experimental environment demonstration and long-term test. Its working principle is as follows:
Phase change energy storage technology is a high-tech based on phase change energy storage materials; The phase change energy storage air handling unit uses outdoor fresh air to cool the mobile communication base station equipment, and at the same time stores redundant cold energy. When the outdoor temperature cannot meet the requirements, it uses the stored cold energy to cool the computer room. The contradiction between energy supply and demand in time and space has been solved, the utilization rate of natural resources has been effectively improved, and the comprehensive annual energy saving rate has reached 50%.
