Radisson Blu Hotel Al Hassa

The project consists of 3 buildings:

• Hotel: 10 Floors with 164 Guest rooms, 14 Suites and 6 Royal suites.
• Luxurious Wedding Hall.
• Business Center: 1 Floors with 9 Meeting Rooms.
• Restaurant: 5 stars restaurant at GF and 5 stars restaurant two floors at 9th and 10th.

Total cooling capacity of the project is 3,092 HP with 544 indoor units,
5 AHUs and 10 FAHUs connected to 143 LG Multi V Systems.??

During the design stage of Radisson Blu Hotel, the designer faced several challenges which was solved by using LG Multi V (VRF system) as illustrated below:

?

• Limitation of power source (MVA) available at the site.
  VRF system needs power source approximately 20% less than other HVAC solutions.
• Reducing the energy consumption based on Saudi Vision 2030.
  According to Saudi Standards, Metrology and Quality Organization (SASO). VRF systems have the highest EER & SEER among HVAC solutions.
• Limited installation space.
  The foot print and clearance space needed for VRF systems are 35% - 50% less than other HVAC solutions.
  Computational fluid dynamic (CFD) analysis was done for critical spaces of outdoor units to insure that the ambient temperature surrounding them is within the operation range (below 55° C).??
• Allowable piping length between indoor and outdoor units.
  Single DX split unit has limitations for both total pipe length and allowable elevation difference which makes it not applicable to be used on high rise buildings, while VRF system has a wider range of piping network.? ?
• Integration with building management system (BMS).
  By using VRF system, HVAC control can be integrated with BMS system without additional accessories and costs.?
