Results of calculations and experimental investigations of the refrigerator realizing a throttle cycle of Linde with the temperature in the refrigerated room from —60 to — 70 °C are presented. The refrigerator has been developed on the basis of commercially produced hermetic freon compressor charged with a blend refrigerant R14/R22/R23 instead ofR22.

The manufacturing departments of International Comfort Product, USA, are located in Lewisburg, Tennessee. It is one of the world's leading manufacturers of home heating and air conditioning equipment. Tempstar brand products are designed and manufactured in world-class facilities and advanced technology. The ISO 9001 certification honored by International Comfort Product is proof that Tempstar is a product you can rely on. Such installations are the most optimal and economical way to create a comfortable climate in modern cottages. This equipment has a Certificate of Conformity of the GOSSTANDART OF RUSSIA and a Permit of the GOSSORTEHNADZOR OF RUSSIA. It has been supplied to the territory of Russia and the CIS over the past 2 years and is in high demand among consumers.

The base of a rational use of natural cold is the application of air heat exchangers in refrigerating installations.

Thus, it is practical to use an air superchiller of liquid ammonia. This will ensure a more stable operation of the ammonia pump switched on at low temperatures of the outside air and installed after the vertical receiver.

A heat exchanger based on porous materials with the average coefficient of heat transfer 65 Wt/(m2*K) was used as an air superchiller.

Semi-hermetic screw compressors of the German company BITZER are increasingly being used in refrigeration due to their compactness, reliability, and the possibility of combining compressors of the same or different performance and design in a refrigeration system to obtain different temperature conditions.

For a decade, Airkul has been operating on the Russian market of refrigeration equipment. During this time, she has gained significant experience in equipping enterprises of the fishing, fish processing industry and fishing vessels. Aircool LLC designs and manufactures refrigeration equipment for storing fish and seafood in holds, equips provision chambers with cold and replaces and commissions central air conditioners.

Over the past few years, the market for industrial, commercial and technological refrigeration equipment has seen a steady increase in the share and growth of the level of Russian manufacturers.

In March 2004, at the key European exhibition of thermal insulation materials ISO in the German city of Wiesbaden, representing 120 participants from 11 countries of the world, ARMACELL was awarded the international quality award ISO Award 2004. The international jury recognized the thermal insulation material ARMAFLEX® as the best among analogues, explaining his decision: “The invention of ARMAFLEX®, the world's first flexible insulation material, marked the birth of an entire industry of flexible technical thermal insulation. ARMAFLEX® has excellent technical characteristics that are constantly getting better.”

The TRANSAS Company, closely cooperating with educational institutions, design and research organizations, has accumulated considerable experience in the development and creation of simulators for various purposes, which are widely used in Russia and abroad both by industrial structures and educational institutions. Hundreds of educational institutions and organizations around the world (in the UK, India, Iran, Spain, China, Russia, USA, Philippines, Finland, France, Sweden, South Korea, Japan and other countries) are equipped with our simulators for various purposes. In the last two years alone, we have installed 95 simulators in 27 countries. The general principles, purpose and structure of the training complex “Refrigeration Plant”, as well as the simulators included in the complex “Refrigeration Unit of Provision Warehouses” and “Automated Refrigeration Unit of the Air Conditioning System” were discussed in the publication in the journal “Refrigeration Technology” No. 4/2004.

The 14th International Exhibition of Household Appliances and Electronics (“CEM-2004”), organized by ITE LLCnpn with the assistance of ZAO Expocentre, was held at the exhibition complex on Krasnaya Presnya on April 26-29, 2004. 13 countries from near and far abroad (at the beginning of the 90s, 80-100 countries participated in CEM exhibitions). The sharp decrease in the number of exhibitors and exhibition space is explained not only by the decline in the interest of foreign companies in the exhibition of household and electronic equipment, but also by the fact that most of them have entrusted the right to show their equipment to Russian commercial representatives. The latter circumstance could not but affect the assortment and quality of the samples on display. All merchants focused on those models that are most in demand on the Russian market today, that is, they can bring profit now, and not in the distant future.
