In July, the "HUAZHIWANXIANG world" in Jinan, with a total height of 246 meters, won the China Steel Structure Gold Award. There are 5 super high-rise buildings, the heat recovery air conditioning system of Holtop provides strong support for energy saving. Compared with the air conditioning system without heat recovery, the Holtop heat recovery air conditioning system's total energy saving is achieved by more than 45%.
"HUAZHIWANXIANG” world in Jinan is a large-scale commercial complex project cooperated by Holtop and China Resources Land Limited. After signing the strategic cooperation of the fresh air system of both parties, China Resources Land Limited highly recognized the product quality and service of Holtop and successively carried out cooperation in more fields. In the air treatment system of Wanxiang World high-rise buildings, the economic and social benefits brought by the Holtop heat recovery unit provide a strong guarantee for the complex operation in the future.
"HUAZHIWANXIANG” world is located in Lixia District, Jinan City, with a total area of more than 440 acres and a total of 6 plots. It is planned to construct super high-rise business buildings of 246 meters, 188 meters, 148 meters, and 125 meters, and super high-rise apartments of 211 meters, etc. In terms of architectural form, WANXIANG world changes the traditional commercial form through indoor and outdoor elements such as blocks and shopping malls, single-family buildings and podium buildings, squares and courtyards, and builds harmonious relationships among city, history, commerce, nature, and people to create a new urban space in line with future customer behavior.
In high-rise commercial buildings, the energy consumption of central air conditioning is about 60% of the whole building’s energy consumption. Improving indoor air quality, comfort and air conditioning energy consumption is always an irreconcilable contradiction. Therefore, whether the air conditioning system saves energy also determines the cost of building operations in the future. In the high-rise building of WANXIANG world, the Holtop rotary type heat recovery air conditioning system is adopted and used the heat recovery technology to recover the exhaust air energy, which can not only improve the air comfort and freshness but also reduce the energy consumption of the air conditioning system. At the same time, cold and heat source units with smaller specifications can be selected, reducing the initial investment in equipment.
The main component to realize the energy saving of air conditioning system is the Holtop rotary type heat exchanger. Through the repeated operation of the rotary, the energy contained in the exhaust air is continuously transferred to the fresh air. International advanced molecular sieve coating technology ensures efficient heat transfer ability, self-cleaning and flexible sealing technology can effectively avoid air cross pollution, total heat and sensible heat are two heat transfer forms that can match different use places. In WANXIANG world project, a single unit can handle a very large volume of fresh air, and the rotary heat exchanger can achieve efficient heat transfer while occupying a small box, which is especially suitable for use in this kind of system.
In WANXIANG world project, the total air supply volume of the Holtop heat recovery air unit is up to 400,000 m3/h. According to the calculation of energy-saving benefits under comprehensive working conditions in summer, winter, and transition seasons, the annual cost saving of the heat recovery air conditioning system is considerable, which can be regarded as an energy-saving tool.
In the field of air treatment and heat recovery, Holtop has been an industry leader, participating in the development of a number of industry standards. In modern buildings, the use of heat recovery air conditioning systems has gradually become the industry norm. In more and more super high-rise buildings, the Holtop heat recovery air conditioning system is playing an important role, which provides better air quality and more energy-saving system.
