New development of JSC ZEL-RUS06/12/2017
Scientifically technical center JSC ZEL-Rus finished development of a series of energetically effective terrace household and commercial refrigerators with a low sound power intended for operation both in the countries with a temperate climate, and in tropical climatic zones at a temperature of air up to 60 degrees Celsius in not conditioned rooms and in the open air on the basis of specially developed series of tight refrigerating compressors with the built-in liquid cooling system.
Refrigerators are executed in the tight moisture-proof threw – plastic cases with thermal insulation.
For ensuring safe operation of refrigerators at operation on the street and low noise level all electric units and units of the refrigerator of these refrigerators, including the compressor, are structurally removed in thermal insulation.
The refrigerator of this terrace refrigerator consists of the special tight compressor with the built-in liquid cooling system, innovative system the drosseliruyushchikh of elements, the standard filter of a dehumidifier, evaporators of cameras of cooling, preliminary and main condensers.
Cooling of the main and preliminary condensers located on lateral external walls of a refrigerating case is carried out by natural static air convection.
Cooling of the tight compressor is carried out automatically, own built-in system of liquid cooling of the compressor which isn’t demanding any additional natural convection or compulsory external ventilating cooling. Cooling is carried out at the expense of a patent method of heat removal from the compressor elements heated in the course of work in the preliminary condenser.
High vibration acoustic characteristics of the developed refrigerators on the basis of the compressor with cooling are an important indicator of competitiveness of these products. They are realized in the form of a complex of the technical solutions allowing to reduce the noise level of refrigerators at the expense of the additional systems of sound insulation which became possible to application, a sound absorption and muffling of a sound.
INNOVATIVE DEVELOPMENT IN COMPRESSOR MANUFACTURING17/10/2017
The staff of Scientific and technological center of ZEL-RUS headed by professor Naberezhenykh A.I. tests of advanced compressors for the household refrigerators intended for work in the conditions of tropical climate at ambient temperatures to 55 °C were carried out.
As the additional cooling system specially developed cylinder head cooling system which allows to lower the working temperature of the compressor without change of its construct was used. The carried-out tests proved efficiency of the developed cooling system and possibility of its application on any models of compressors, as productions of the ZELT company, and as a part of compressors of other producers.
In the course of tests it was succeeded to bring a trade freezing case on which the advanced compressor was previously installed, to working temperature and to achieve its stable work during the whole time of tests at ambient temperature in the test camera of +55 °C. Low cost of works on completion of serial compressors and substantial increase of their efficiency will allow to introduce this development in production soon and to provide the refrigerating industry with the new innovative compressor.
Opening of scientific and technological center of ZEL RUS16/10/2017
In the ZEL-RUS company the Scientific and technological center is formed. The main activities of the center are scientific activity in the field of compressors and educational activities for training of the personnel of the leading plants on production of refrigerating equipment in the territory of the Russian Federation, and also the staff of other companies wishing to improve the skills in the directions connected with the device and production of refrigerating equipment.
The staff of the center are teachers of profile disciplines, professors, doctors of science and research associates of the leading HIGHER EDUCATION INSTITUTIONS of Moscow. Now in the center training programs according to which training of students of professional development will be provided further are developed.
After the termination of a course and successful delivery of final qualification examinations the standard certificate will be issued.
