Bitzer screw compressors are 20 years old


20 years ago, Bitzer founded a new business area - the production of screw compressors for refrigeration and air conditioning systems. The success and achievements of Bitzer Kulmaschinenbau GmbH began with series production of the OST7061 type screw compressor in the assembly plant in Sindelfingen on January 26, 1983. At that time, annual production was only about 500 compressors. By the end of 2003 it should increase to about 13,600 compressors. The production of this series in 1983 and its successful operation helped to refute the argument that screw compressors with a volumetric capacity of less than 300 m³/h should not be used.

Autonomous cooling system for high-power ion lasers

Ulitenko A.I., Praded V.V., Pushkin V.A.


The problems of intensification of conditions for heat exchange in « liquid- to-air» refrigerating systems on the basis of heat dissipating elements with spiral-wire finning are considered. The analytical correlations for the calculation and optimization of such systems are presented. Based on the investigations a high efficiency air heat exchanger with the dissipated capacity up to 16 kW has been designed. The design of self-contained refrigeration system for powerful gas lasers as used in medical apparatuses for diagnostics of cancer diseases, in show-business and in a number of devices operated in mobile objects is described.

Stationary ammonia gas analyzer "Signal-03A"


Ammonia refrigeration plants (ARF) belong to the objects of high danger, which is connected with high toxicity of ammonia and explosiveness of ammonia-air mixture.
The control and timely detection of ammonia leaks is necessary to provide safe operation of ACU as well as to protect the health of the operating personnel.
SIGNAL-03A" device was developed taking into account "Rules of ammonia and refrigerating plants construction and security" (PB-09-220-98) and meets all the requirements.

Ice-breaking: the physics of the process and practice

Kuznetsov B.A., Goncharova G.Y., Leppyanen H.


For information: a man-day of an experienced "Ledovar" invited from Scandinavian countries by some Russian clubs costs the latter from $1,000 to $5,000. In Russia it costs the latter between 1000 and 5000 dollars. The freezing process takes from three days to two weeks, depending on the technology used.
This publication opens a series of articles in which their authors will try to summarize their experience in the design and operation of engineering and technological systems of sports ice facilities.
