The Vatican Museums will be installing a new landmark heating, ventilating, and air conditioning system for the Sistine  Chapel, specially designed to address the challenges of protecting Michelangelo’s masterpieces against deterioration. 

The Governate of the Vatican City State and Carrier on Wednesday said the new system is expected to be installed and  commissioned by the third quarter of 2014.

The new system, which replaces a Carrier system installed in the early 1990s, is designed to have twice the efficiency and three times the capacity of the previous system.
