Abstract

The current environmental situation is forcing developers of household refrigeration equipment to reconsider their attitude to absorption refrigeration device (ARD), which can be considered as one of the alternative options for switching to environmentally friendly refrigerants. At the same time, ARDs have increased energy consumption in comparison with similar compression models. It is shown that the main element ensuring the effective ARD operation is a reflux condenser. Modeling has shown that to ensure complete purification of the ammonia vapor stream under severe conditions of ARD operation, the thickness of the thermal insulation of the reflux condenser lifting section in the form of fiberglass fabric should be 3...4 mm thick
