Carrier has recently installed an HVAC solution  for the Sistine Chapel to help preserve Michelangelo’s masterpieces against  deterioration caused by increasing numbers of visitors.The system design was  approved by an international audience specializing in cultural heritage  preservation. Carrier is a part of UTC Building & Industrial Systems, a  unit of United Technologies Corporation. The new system uses two Carrier AquaForce®  30XWV watercooled chillers with Greenspeed® intelligence, each with 580 kW  capacity. It leverages specially designed software and components, as well as  patented, energy-saving technologies to maintain optimal climate conditions for  the protection of the paintings within the chapel. An intelligent system of  controls, linked with an advanced video application, enables the system to  anticipate visitor levels and adjust its performance intuitively. The new  system delivers twice the efficiency and three times the capacity of the former  system, which was built and installed by Carrier in the early 1990s. To ensure  the smooth operation of the new system, the Vatican has chosen to enter into a  five-year maintenance contract with Carrier Distribution Italy SpA.
