MAX at the turn of the XXI century
Abstract
The International Academy of Refrigeration (MAX), despite the difficult socio-economic and socio-political conditions, has retained its social status and creative potential. The process of re-registration of regional branches (RO) is being completed. Regional branches were created and legally formalized in Petrozavodsk (Karelian District) and Vladivostok (Far East District). The registration of documents of the Baltic Interethnic Branch, which includes representatives of Latvia, Lithuania and Estonia, is nearing completion.

Studies of contact and crevice corrosion of structural materials in an aqueous solution of lithium bromide
Abstract
Results of the investigation of two-metal and crevice corrosion of carbon steel and copper alloys in aqueous solution of lithium bromide are presented in the article. The effect of some inhibitors on corrosion of copper alloys and carbon steel in liquid, vapour phases and on the border of phases separation was investigaged. It was found, that the inhibiting composition, consisting of lithium chromate, lithium hydroxide, К-inhibitor and a surfactant provides an effective protection from corrosion in all the phases of a 64% solution of lithium bromide.

Special development of the company VOSK (Germany) - low-temperature semi-hermetic compressor series HA
Abstract
7 years ago, the research center of the VOSK company was given the task of designing a model of a freon semi-hermetic refrigeration compressor based on the most advanced types and modifications of open (omental) compressors of the F series, which would radically differ from similar products of competing firms already existing on the world market.

Highly efficient microclimate system in the indoor swimming pool of the sports school No. 7
Abstract
A highly efficent system of microclimate in a swimming-pool area of a sports school No.7is described. A distinguishing feature of the inlet and discharge units consists in the use of heat of the exhaust air for heating of the incoming outside air.
Thermotechnical efficiency of the heat utilization installation with intermediate heat carrier has been increased by using of an additional system of air superheat in the upper zone of swimming-pool area.

CJSC "ORLEKS": domestic automatic devices for refrigeration equipment
Abstract
CJSC "Orleks" (former Order of Lenin PO "Prompribor", Orel) traditionally for over 40 years has been producing instruments and automation devices for monitoring and regulating temperature, pressure, engine speed and other parameters in industrial, transport and household refrigeration equipment, electrothermal equipment, air conditioning, ventilation and heating systems, diesel plants and other facilities. Currently, more than 100 types of instrumentation products with more than 1000 modifications are being produced. However, precision automation devices for refrigeration equipment remain the main activity of the enterprise. These are primarily thermostats (TAM 112-1M, TAM 133-1M, 145-2M, TAM 114-1M) for household refrigerators and freezers, electromechanical pressure and temperature controllers (DEM 102, DEM 105, DEM 108, DEM 202, TAM 102 , TAM 103, TAM 113) for industrial and commercial refrigeration machines, cabinets and counters. The existing quality management system at CJSC "Orleks" is certified by the Lloyd's Register for compliance with ISO 9001:1994 standards and applies to the design and manufacture of the main types of products. The devices listed above are also certified by other leading foreign testing centers: BEAB, VDE.

Obtaining high-purity cryoproducts
Abstract
At present, the main products of air separation - oxygen, nitrogen and argon - are widely used in various branches of science and technology. At the same time, in a number of technological processes, high requirements are imposed on the purity of these products, according to which the content of impurities in them must be several orders of magnitude lower than is allowed by the current GOSTs inn TU. The same requirements apply to the purity of some other gases used in low temperature technology, such as hydrogen, helium and carbon dioxide. In this case, the limiting total volumetric content of microimpurities of individual components in a number of cases should not exceed 10~6-10~7%.

Plate freezers
Abstract
For freezing fish and seafood on ships and coastal enterprises of the fishing industry, plate freezers are widely used. The products frozen in them have the correct shape, which facilitates their storage and packaging. It is convenient to further load the goods into transport and put them in storage chambers.

Bitzer Compressor Cooling System with Controlled Injection Refrigerant (CIC)*
Abstract
Installation of the cooling system. In cases where the compressor is ordered complete with an OS system, a control unit, a temperature sensor with its connecting wire and an injector (one injector for four-cylinder compressors, two for six-cylinder compressors) are installed on it at the factory. The nozzle is closed with a screw plug. The pulse non-magnetic injection valve, equipped with power supply connectors, is delivered in a separate package to prevent possible damage during transportation. Mount the valve on the compressor before checking the tightness of the circuit.
