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.
