Abstract

The existing ejector systems were analyzed depending on the way in which the refrigerant returns from the condenser to the generator and evaporator. The research focused on gravitational ejector refrigerator in which hydrostatic pressure of the refrigerant allows to equalize pressure differences between heat exchangers located on different levels. Using centrifugal acceleration instead of gravitational allows to decrease significantly the size of a refrigerator. The name roto-gravitational refrigerator was proposed for that kind of refrigerator.One of the problems of small, compact refrigerators is a little amount of refrigerant. Surrounding temperatures when different from typical may cause drying up of the refrigerant in the exchangers and lead to destabilizing the refrigerator's work. A mathematical analysis of thermal and flow processes occurring in the refrigerant has been conducted. A mathematical model of the refrigerant balance and its numerical solution has been proposed. The analysis of the refrigerator accelerating temperature influence on its work parameters has been conducted for exemplary calculations.
