An analysis of the current state of technology shows the prospects for the development of alternative electric heat energy sources for the operation of absorption refrigeration devices (ARDs). It is important in today's minds that the working body of the ARDs is a water-amonia mixture with the addition of inert gas (water, helium or their mixtures) to natural refrigerants and is also absolutely environmentally friendly (maybe zero the significance of the ozone potential and the potential of the “greenhouse” effect). Before achieving the ARDs, it is necessary to maintain minimal heat among the most common types of refrigeration equipment with low cooling capacity, which in many cases means their popularity among consumers. Of particular interest may be ARDs models that use alternative, non-electric thermal energy sources in their work. A series of experimental studies were carried out at the stationary centers of the ARDs. The object was monitored by the ARDs "Kiev" AC-35. The thermal energy supplied to the ARD generator was varied in the range of 50 W to 110 W at 10 W intervals. The lower range of thermal absorption of the generator indicates the effectiveness of the ARD in terms of starting the thermosyphon that is pumped. The upper boundary of the thermal zone of the generator is surrounded by increasing temperatures and the beginning of active corrosion processes. In order to find an algorithm for supplying combined thermal energy, an experimental study of the starting modes of the ARD from a non-operating mill was carried out. The duration of the start-up period in our investigations was punctuated by the entry into stationary mode of the ARD refrigeration chamber. The principle of stationary mode was determined due to the invariability of the temperature in the refrigerating chamber. It has been proven that in order to ensure the safety of the ARD cycle, it is sufficient to use a standard car electric battery with a 70 A·hours 12 V battery. [ABSTRACT FROM AUTHOR]
