Retrofit problems of refrigeration equipment with a turbocharger

Belyaeva O.V., Grebenkov A.Z., Timofeev B.D.

Abstract

Results of analysis of problems connected with the retrofit of refrigeration, equipment with turbocompressor are presented. It is shown that the retrofit of machines of such type should be considered as a temporary measure; in this case it is practical to develop refrigeration equipment with turbocompressor on monosubstances that can be produced in Russia.

Study of the distillation column of the absorption unit of a water-ammonia refrigeration machine of low productivity

Galimova L.V., Nyrov O.A.

Abstract

Results f investigations of the absorption assenmbly rectifying tower of a low-capacity' water-ammonia refrigerating machine are presented. It is shown that the matched type dephlegmator of the offered design ensures formation of sufficient amount ofphlegma and the rectifying tower in the scheme of refrigerating machine has a small influence on its efficiency.

New technique for producing high purity neon and helium using cryogenic technology

Arkharov A.M., Arkharov I.A., Purtov S.N., Bondarenko V.L., Losyakov N.P., Rura V.N., Simonenko Y.M., Savinov M.Y., Kapralov P.A., Volynsky P.I., Bronstein A.S., Golubev A.A., Belov M.Y., Grafov A.P.

Abstract

A complex of plants has been created for wasteless purification of neon and helium at 28... 68K. A single technological chain for obtaining rare gases with the purity up to 99.9999% from atmospheric air has been formed. An analysis of dynamics of world production of neon and main directions of its applications are given.

Suspended ammonia air coolers type AVP

Tovaras N.V., Prozorova T.V.

Abstract

OOO NPF “Khimholodservis” has developed a new series of suspended ammonia air coolers of the AVP type based on the heat exchange surface taken as the basis for the creation of a number of air coolers of the AVN type.
The effectiveness of such a surface (due to optimal geometric parameters) is confirmed by thermal tests.

Piston rings? No problem New piston rings for refrigeration compressors

Afonsky V.P., Vetrenyuk S.T.

Abstract

Reliable, durable and economical operation of reciprocating refrigeration compressors, as well as automobile engines, depends on the performance properties of components and parts. The most important parts of the piston mechanism are sealing and oil scraper rings, which prevent the leakage of compressed gas into the crankcase and the removal of lubricating oil into the compression cavity.
These rings must have high wear resistance and low coefficient of friction, quickly run in and prevent active wear of cylinder liners.

Respirators antigas RPG-67 and universal RU-60M

Abstract

Respirators are designed to protect the respiratory organs from vapor-gaseous harmful substances at concentrations not exceeding 10 ... 15 mg/m3 MPC, and the RU-60M model is also designed to protect against harmful aerosols at concentrations up to 100 mg/m3. They can be used in all climatic zones of Russia at chemically hazardous enterprises, when working with fertilizers and pesticides, on time for painting and loading and unloading.
