China’s 1st 5-star Hotel VRF System Braze-free Retrofitting Project by NEXCON

Intercontinental® Lhasa Paradise Hotel is one of the few high-altitude hotels in the world. The natural landscape around the Lhasa River was fully considered in the initial planning stage. According to the local topography and hydrological conditions, “sky high, the earth far”, “floating white clouds, cascading snow mountain” is the the design concept. With Jiangsu Avenue as the central axis, is divided into three groups of “white triangle buildings” symmetrically, forming a patchwork of snow mountain shapes, standing beside the blue lake, mirrors, blue sky, white clouds, reflections, reflecting each other.

In order not to affect the normal daily business of the hotel to the greatest extent and the local CPPCC meeting in the first half of 2021 to be held as scheduled, the hotel decided to install VRF system with braze-free connection technology. With a total investment of 1.8 billion RMB (275 million USD), the InterContinental® Lhasa Paradise Hotel covers an area of 350 mus (233,450 square meters), with a total construction area of 212,000 square meters, and a total of 2,000 rooms. Retrofitting construction area of this project is about 41,000 square meters. It is the largest five-star hotel in Tibet. The project contains 66 VRF outdoor units and 523 indoor units, with a total cooling capacity of more than 3000kw.

In the early stage of the project, in order to do its best to meet the needs of the project, NEXCON tentatively prepared all materials in production to arrange the required goods for the project. It only took ten days to get the goods ready and shipped by air to Lhasa, then to the project site.

At the same time, NEXCON also sent technical team to Lhasa. On November 18, 2020, the Hoh Xil Conference Hall of the Intercontinental Hotel, the team gave a braze-free connection technology training and operation demonstrations for the installers of this project. The training lasted for 3 hours. The braze-free connection technology and NEXCON products were highly praised by the installers. The installers in charge of this installation all stated that the braze-free installation is convenient, clean, fast and safe. Compared with the conventional brazing installation, this project has reduced installation hours by about 50%. The most important thing is to fully guarantee the hotel’s business as usual without interruption.
