Modern compressors of the Yaroslavl JSC "Kholodmash" for commercial and industrial refrigeration units
Abstract
Despite the problems associated with the transition to the market, the staff of the Yaroslavl JSC "Kholodmash" concentrated its efforts on the development of production, the improvement of compressor technology and compressor building technology. Today Yaroslavl JSC "Kholodmash" has a wide range of compressors produced not only under license, but also on the basis of its own developments. In a short time, it was possible to put into operation an additional 22,000 m2 of production space, conclude a contract for the manufacture of 600,000 compressors per year under a license from Electrolux Compressors, and build a workshop for this. Compressors produced today comply with European quality and safety requirements and are fully interchangeable in terms of technical characteristics and connecting dimensions with similar models of compressors from ASPERA, UNIDAD HERMETICA, L’UNITE HERMETIQUE, etc.
Modern electrically insulating polyester materials, class 200 enamel wire, mineral and polyester refrigerating oils from the best foreign companies (such as MOBIL, SHELL and FUCHS) provide high quality and reliability of compressors when operating on ozone-friendly refrigerants. Quality control is carried out at all stages of production, from the input control of materials and components to testing on stands and final acceptance of compressors

Modernization of compressors for compressing carbon dioxide in the food industry and petrochemistry by switching to operation without lubrication of cylinders and seals
Abstract
In the food industry and petrochemistry, compressors are widely used to compress carbon dioxide with a discharge pressure of 10.0 to 25.0 MPa. Compressors of small mass capacity (from 100 to 250 kg/h) are used in the production of carbon dioxide for food purposes, dry ice production, welding and firefighting. These are compressors CD 1.6 / 2.0, T3CSp- 100/150 (manufacturer - Wurzen, Germany), T100-33-8 (LMF, Austria), KP-UM (Ural Compressor Plant), 2UP-220 / 75 (Krasnodar Compressor Plant), ZUGM (Compressor Plant, Moscow).

Air conditioning, heating and ventilation systems with energy supply from own source
Abstract
A system working on natural gas and used energy, heat and refrigeration supply of buildings is described. Ike heal as obtained in electric generator as a by-product is used for driving the absorption refrigerating machine. Internal heat flows are to good advantage are used in the system of heating, ventilation and air conditioning. A system of climate maintenance in the trade house “Tri Kita" developed by Vente is considered as an example.

Refrigeration compressors and units Bitzer, Maneurop, Aspera
Abstract
In the previous article, published in issue No. 6 of our journal, the whole range of heat exchange equipment of the Finnish company Fincoil, supplied through Arctica Wholesale Ltd., was presented. to the Russian market of refrigeration equipment. In this issue of the magazine, the company introduces readers to its suppliers of refrigeration compressors and compressor units sold in Russia. Large sales volumes of Arctica Wholesale Ltd., and the share of compressor equipment accounts for more than 70% of the trade turnover, can be explained by the precise choice of suppliers of compressor equipment for Russia, as well as the competent pricing policy of the company. Why the managers of Arctica Wholesale Ltd. chose these compressor manufacturers is described in this article.

Improving the Reliability of Absorption Lithium Bromide Heat Converters by Using Corrosion Inhibitors
Abstract
Based on literature data analysis with the consideration of the requirements to the inhibitors under operational conditions ofabsorption lithium bromide heat transformers (A В PT) the corrosion inhibitors are determined which have good prospects for use in ABPT. According to experimental investigations carried out at SPbUNT and PT the effective inhibitory compositions for protection of ABPT manufactured both from carbon steels and using copper-nickel alloys are proposed.
