Refrigeration of air conditioning systems in the restored Cathedral of Christ the Savior in Moscow

In the 830s, the building of the Cathedral of Christ the Savior was blown up and the construction of a high-rise building of the Palace of Soviets began in its place.
A huge pit was dug and the metal structures of the foundation of the high-rise building were erected. At the beginning of the Great Patriotic War, construction was stopped, the metal structures were cut off and used as anti-tank barriers in the defense of Moscow. After the end of the war, the construction of the Palace of Soviets was not resumed, and an outdoor swimming pool was built on the site of the foundation pit.
In the mid-90s, with the active participation of Moscow Mayor Yu.M. Luzhkov, a decision was made to eliminate the pool and restore the Cathedral of Christ the Savior on this site. The design and architectural work on the reconstruction of the temple was led by the director of the Mosproekt-2 Institute M.M. Posokhin
