Analysis of test results of a household absorption refrigerating appliance on an electric and gas source of thermal energy

One of the biggest challenges for refrigeration systems is their conversion to environmentally friendly refrigerants. This attracts attention developers household equipment absorption devices (ARD), which include an unit (ARU). ARD working fluid consists natural components - ammonia water solution with addition inert gas (hydrogen). Therefore, use ARU can be considered as one options transferring In recent years, in connection rapidly developing gasification population Europe, alternative has arisen operation on gas. Natural become electrical energy stationary operating conditions appliances. Thus, object study was a single-chamber refrigerator low-temperature compartment "Kiev-410" (Ukraine). this paper, aimed at comparing thermal modes and costs electric To solve this, it necessary determine temperatures characteristic points apparatus chamber, well consumption absorption-type accordance regulatory documents, various values load thermosyphon ambient temperatures. The studies were carried out elevated outdoor temperatures: 28–33 ° С. range loads heater 50–130 W. numerical burner (2.8–8.8) • 10-6 m3/s. process conducting experimental ARD, results obtained showing economic prospects At same time, increased useful volume (200 dm3 above) greatest prospects. daily them are 0.078...0.084 USD, 23...27 % lower than case using electricity. When built into heating hot supply system, becomes possible temperature potential waste products combustion completely eliminate costs.
