Hotel
Project Type
Renovation

Challenge Hotel
The existing two-pipe chiller system only allowed for either heating or cooling. The system was detereorating and not providing the ability to heat and col rooms independently. A replacement system was required to integrate with existing building controls, and comply with CSA B52 refrigerant limitations.

Daikin Solution
The Sheraton Center Toronto decided to install a Daikin VRV system. The decision was based on the systems ability to operate in heating and cooling modes simultaneously between guest suites. The Daikin VRV system also operates at lower sound levels and provided a competitive total installation cost compared to other options.

Challenge Multi Family
Retrofitin an older landmark building in New York City is never easy. Ceiling height restriction, architectural design and logistical issues of transporting equipment in a R10 zone, the highest residential density in the city, were some of the key considerations and challenges for this project. These residences required an unobtrusive, quiet and individually controlled HVAC system that could match the luxurious architectural design of the 220,000 ft2, 20-story Uppeer East side building that includes 56 residences and numerous amenities.

Daikin Solution
Water-Cooled BRB was chosen over chilled water systems or water-source heat pump systems due to the indoor units and condensing units' low sound levels, energy efficiency and space savind design, including Daikin's indoor ducted fan coil units that satisfy the interior architectural requirements and space constraints of the individual condominiums. In addition, Daikin VRV offers individual zone temperature control for each condominium which was an important specification from Macklowe Properties, the developer.
