90 years ago, in January 1912, the first issue of the magazine " Kholodilnoye Delo" (the predecessor of today's jubilee - the magazine " Kholodilnaya Tekhnika") was published in Russia. The magazine was founded by the Moscow Committee on Refrigeration under the Moscow Society of Agriculture. Its publisher was M. A. Ilyashenko, a member of the committee, and M. T. Zarochentsev, secretary of the committee, was the editor. All members of the committee, including V.E. Tsydzik, O.O. Dreyer, Y.Y. Nikitinsky, S.A.

The use of cold to preserve perishable food products has been known to mankind since ancient times. It is enough to remember the ancient Greek and Roman states, where caves in the mountains with all kinds of ventilation passages and holes were used to preserve vegetables, fruits and wines. Ancient Romans dug out deep cellars in the ground, where in the winter and summer a constant temperature of 8... 10 °С. Similar refrigerators in the mountains were also built in the Middle Ages in the Balkan countries, Crimea, Moldavia and the Caucasus. In some places people managed to create caves with sufficiently cold and dry air. The water of streams and wells was also used to preserve food in summer.

The paper deals with the main direction of development of cryology the science of refrigeration, methods of its production and practical application. Special attention is given to problems of decrease of energy consumption and reduction of adverse effects on the environment.

The mechanisms of depleting the stratospheric ozone layer by chlorofluorocarbons are described. A generally accepted concept of ozone crisis has been confirmed.

New assemblies of refrigerating compressor were developed by NDF «Khimkholodservice» company oil coolers, oil separators, automation systems, pm panels with systems of smooth start — are described.

Use of these assemblies meeting the won technical level, will considerably impove operational characteristics and service life of Russian refrigerating units and machines.

The conference was organized by the International Institute of Refrigeration with the active assistance of the University of Zagreb. The conference had two sections: Refrigerant Management and CFC Destruction Technologies.
