As the population of the cities worldwide is growing fast, the need for high-rise buildings is gaining momentum. It is very significant, therefore, to know the requirements of heating and cooling of these buildings. Such requirements include capital costs, architectural and structural installation constraints, environmental concerns and acceptable acoustic levels.
On the 29th of May Daikin Europe organized a seminar on VRV solutions in high rise buildings in Seville, Spain. Our company attended the seminar together with a number of selected clients interested in this topic. High rise buildings face a great deal of challenges when it comes to their cooling and heating requirements. Different installation possibilities exist to cater for differing situations, like the top floor, or the basement, or the technical equipment floor. The choice will affect parameters such as appearance, structural strength, duct sizes and piping length and available floor space. The same works in the opposite direction, where building design parameters will define the installation method. The seminar mainly focused on Daikin’s water-based VRV systems. Through several examples of real high rise buildings, the participants had the opportunity to understand the advantages and disadvantages of different options. What is important is that with Daikin there is no unique solution. One can explore various possibilities and be creative based on the needs of every building.
A water-cooled VRV system is essential in high rise buildings, especially when low external noise is critical, or when the air quality is very corrosive, or when there is not enough space for outdoor units, or under extreme outdoor temperatures. The same goes for refurbishment projects where it is possible to link the VRV to existing water piping. An excellent case study was Puerto Triana (Sevilla Tower), the very same building where the seminar took place. The participants had the opportunity not only to understand the theoretical part but to actually visit the site and see the systems in operation. Puerto Triana, is a 37- floor building, which was initially built to serve as a business center. Along the way the decision was made to convert it partly into a hotel. Floors 1-24 serve as a business center and floors 25-37 as a hotel.
The conversion faced many challenges, since a hotel obviously has different needs than a business center. Unbalanced cooling requirements offered the right conditions to use heat recovery systems with individual heating and cooling functionality, thus providing the hotel with integrated hot water supply. The compact sizes of Daikin’s VRV systems occupy a minimal space in the technical equipment room of the building, therefore having no visual impact on the building. What is equally important, they operate in silence. Daikin VRV systems operate on low running cost, they achieve better seasonal efficiency levels than other technologies and they provide better air quality in the air-conditioned areas. In conclusion, they provide an excellent solution for a healthier and more efficient building.
