VATICAN CITY, June 17, 2014 /PRNewswire/ -- The Governate of the Vatican City State and Carrier today announced the start of the installation of a landmark heating, ventilating and air-conditioning (HVAC) system for the Sistine Chapel, specially designed to address the challenges of protecting Michelangelo's masterpieces against deterioration. Carrier's groundbreaking system, developed by the company's expert global team of AdvanTE 3C engineers and backed by its industry-leading research and development resources, is expected to be installed and commissioned by the third quarter of 2014. Carrier, the world's leader in high-technology heating, air-conditioning and refrigeration solutions, is a part of UTC Building & Industrial Systems, a unit of United Technologies Corp. (NYSE: UTX). The new system, which replaces a Carrier system installed in the early 1990s, is designed to deliver exceptional performance with twice the efficiency and three times the capacity of the previous system. The custom-engineered solution uses first-of-its-kind energy-saving technologies, as well as industry-leading approaches to minimize noise and limit air motion around the frescoes. In order to ensure outstanding reliability, highly controlled temperature and humidity levels, and optimal airflow management, the design team completed extensive modeling using a specially developed application. Once installed, the system is designed to be virtually unnoticeable to visitors. In addition, the Governate of the Vatican City State and United Technologies Corp. (UTC) have entered into an agreement to ensure the protection and safety of the Vatican Museums' artwork, spaces and visitors through the deployment of building technologies from UTC companies. According to the terms of the agreement, the parties will work together on integrated solutions spanning HVAC, elevators and escalators, fire detection and alarm, fire suppression and safety, electronic security, access control, video surveillance services and related software solutions, from brands such as Carrier, Otis, Lenel, Kidde, Chubb and Marioff.
