Richmond Hill location is the second Data Center project we have completed with Urbacon. The first one was supplied and installed in Montreal. The customer was extremely happy and wanted the same Swegon solution again. The ventilation system has 2 units installed to provide 100% ventilation redundancy; so that there is no system down time. The ventilation units are integrated with direct spray evaporative cooling and humidification to improve the effectiveness of the energy recovery and energy transfer from the server bays.
In 2015, the new building manager of the Harvard University Science Center had ambitious plans to cut energy costs in a project that involved fitting out a space for the building operations office and upgrading a classroom along with other offices. The building requirements included a new chilled beam system, a new air handler, demand-controlled ventilation capabilities, and integration with the campus-wide BMS. Since other spaces on the campus had been renovated successfully with Swegon diffusers, Harvard called on Swegon again in April 2015 to provide a chilled beam solution for a renovated math classroom, professors’ offices, and the building manager’s office suite for the Harvard University Science Center. With an expected delivery date of September 2015, Swegon had to take on the challenge of delivering the solution within a short timeframe.
Two GOLD RX 30 units were installed side-by-side and connected to a common air distribution system. The unit controls were configured for a lead lag operation as required by the Building Management System (BMS). This control sequence allowed the units to run alternately to extend the life of the units and allowed the backup unit to be tested monthly. Unit and system maintenance along with filter changes can be done without affecting the system’s operation and reliability.
Swegon North America worked with DND Engineering in Montreal and Contractor Modern Niagara to complete this project for a Private Client. The ventilation units installed were integrated with direct spray evaporative cooling to improve efficiency of heat transfer from the servers.
The Parasol VAV units reduced energy consumption in these areas in two ways: first, by utilizing its unoccupied mode to deliver minimum required flow when rooms are unoccupied, and second, by matching load to ventilation.
