From the very first words the reporter clearly defined the problems to be discussed by the congress: tendencies on the world, Russian and regional ice-cream markets; product quality; creation of mutually beneficial relations between ice-cream producers and trading organizations. The general results of the work of the food industry enterprises of the country, including ice-cream producers, were presented in the report. It was noted that in 2002 376 thousand tons of ice cream were produced, which is by 12 thousand tons or 3,4% more than in 2001.

In the year of the 300th anniversary of St. Petersburg the International Scientific and Technical Conference "Natural Refrigerants - an Alternative to Global Warming" was held in St. Petersburg State University of Low Temperature and Food Technologies (SPbSUNiPT) on February 4, 2003. The Conference was organized by the SPbSUNiPT, the International Academy of Refrigeration (IARC), and the Working Group "Properties of Refrigerants and Heat Carriers" of the RAS Scientific Council on Problems in Thermal Physics and Heat Power Engineering. Among the participants of the Conference are: International Academy of Higher School Science, Odessa State Academy of Food Industry, Institute of Energy Problems of the National Academy of Sciences of Belarus, Mogilev State Food University (Belarus), JSC "Shark Shaboda" (Uzbekistan), JSC "VNIIholodmash-Holding", JSC "Rosmyasomoltorg", Non-profit City Organization "Moscow Security Fund", Moscow Power Engineering Institute (Technical University), Moscow State Technical University named after N.E. Bauman. N.E.

Thermophysical and ecological characteristics of natural refrigerants — substitutes for CFC and HCFC — are considered. Main characteristics of the refrigerating cycle during operation on the substitutes of R12, R13 and R22 are presented. Vivid comparison of substituting refrigerants by their volumetric refrigerating effect and the temperature in the compressor outlet is given. In conclusion, recommendations on the use of particular alternative refrigerants are presented, and in is shown that it is impractical for the countries of CIS to take out of use HCFC refrigerants before the appointed time (prior to 2030).

As a result of more than 30 years of experience, design and implementation of many promising innovations, a new generation of "GRASSO" screw compressor units was created. They were developed specifically for industrial refrigeration plants taking into account the operating conditions in Russia units FMS3-900, FMS3-1800 and FMS3-2500, as well as the requirements of Gosgortechnadzor of the Russian Federation.

Recently in Russia, with the development of market relations, the output of various types of meat semi-finished products, sausages and frankfurters has significantly increased. In this connection requirements to sanitary and hygienic conditions in industrial premises of meat industry enterprises increase. These conditions can be achieved by means of technological air conditioning systems installed in the respective shops.

LU-VE Group has successfully started production of the new Big Giants large capacity fluid coolers of the SHLD series, which were first officially presented at the IKK-2002 International Exhibition in Nuremberg. Customers have been waiting a long time for these models to enter series production. The most powerful chillers have already been purchased by several international companies and installed at large industrial facilities (e.g., in Germany).

At present, the cost of energy resources, in particular electricity, has increased sharply, so the problem of saving electricity has become particularly important. Analysis of the device and operation of refrigeration units allows us to conclude that it is possible to achieve energy saving by implementing simple and costless measures.
