The recent trend towards expanding the scope of application of environmentally friendly natural refrigerants, including ammonia, has caused an increased interest of the refrigeration community in the safety problems of ammonia refrigeration units (ACU). It is known that ammonia has two significant drawbacks: it is toxic at concentrations in air above 0.02 mg/dm3 and explosive at concentrations in air of 16...28% by volume. In large refrigeration systems containing large amounts of ammonia, the possibility of leakage accidents is greatly increased. Therefore, the main task when working on ammonia as a refrigerant is to reduce the ammonia capacity of refrigeration units.
It was precisely this problem and methods of solving it, both technical and economic, normative and legal, that was devoted to the scientific and technical conference held in Moscow on April 11–13, 2001 “On measures to reduce the risk of accidents and emergencies during the operation of facilities using ammonia refrigeration units (AHU), based on the reduction of ammonia capacity and improvement of cold production technology”.
The initiator of the conference was the State Institute for the Design of Refrigerators, Ice Cream Factories, Dry and Water Ice and Liquid Carbon Dioxide Plants “Giprokholod”. It was organized by the Ministry of Emergency Situations of Russia, Gosgortekhnadzor of Russia and Giproholod with the support of VNIHI. The conference was attended by representatives of research and design institutes, universities, manufacturers and consumers of ammonia refrigeration equipment, enterprises involved in automation systems, organizations engaged in the protection of the population.
The interest in the problem of ACS safety of such various departments indicates its relevance and the need to develop a unified approach to this problem, on the basis of which each department will be able to implement effective measures to reduce the risk of accidents at ACS

In the future, for the next few years, the main design objects for Giproholod will remain ammonia refrigeration units of large and medium-sized industrial and commercial refrigerators, cold storage plants, ice cream factories, fruit and vegetable bases and other food enterprises (dairy and meat processing plants, breweries, etc.).

The commercial and industrial company "Rosmyasomoltorg" is the largest association of refrigeration enterprises in Russia and includes more than 160 joint-stock companies established on the basis of cold storage facilities of the Ministry of Trade of the RSFSR, with a total capacity of refrigeration chambers of more than 1 million 300 thousand tons, 4 including about 80 ice cream shops, 17 dry ice shops, as well as a number of production sites that produce sausages, semi-finished meat products, fish products, wafers and confectionery, etc.

The condition for success in business for any enterprise that produces frozen and chilled food is the rhythmic and uninterrupted operation of refrigeration equipment. In many ways, this depends on its reliability and the capacity of the refrigerating chamber used at the enterprise. With many years of experience in design, supply and installation, Aircool offers cold rooms and warehouses of any volume and size.

YORK Refrigeration ApS (Denmark) was established in 1999 as a result of the acquisition by YORK International Corporation (USA) of the European companies GRAM, SABO and STAL. Being a division of YORK International (USA), “ YORK Refrigeration ApS (Denmark) fully satisfies the needs of its customers around the world, including Russia, in refrigeration equipment and spare parts. For more fruitful work with Russian customers, a representative office of YORK Refrigeration ApS was opened in Moscow, working in close contact with CJSC YORK International. Such cooperation allows prompt installation, start-up and adjustment of equipment, service maintenance and supply of original spare parts for the equipment of YORK, GRAM, SABRO and STAL companies. In the near future, a warehouse of spare parts is being prepared for opening, which will significantly reduce the time of their delivery.

Since its foundation in 1928, LU-VE CONTARDO has been a recognized world leader in the design and manufacture of air conditioning, refrigeration and heat exchange equipment. Thanks to ongoing developments, designing new and improving existing models, the entire range of the company's products meets both the highest international standards and the needs of the most demanding consumers.
The range of manufactured products includes several hundred models: from small - a few hundred watts, to real giants, whose performance exceeds 1 MW. All LU-VE products fully comply with the ISO 9001 standard, which serves as a recognition of the absolute quality and reliability of products .

July 1, 2001 was the 60th anniversary of the chief engineer of Rosmyasomoltorg JSC, academician of the International Academy of Refrigeration O.A. Bakhvalov

WURM systems are designed to automate the control of processes occurring in the refrigeration machine. In addition, these systems automatically collect data on the operation of the installation, which are transmitted from a computer via a modem over communication lines. This, in particular, allows you to control the operation of the chiller from anywhere in the world using the Internet.
