Sherstyuk V. The influence of thermal and hydraulic irreversibility of processes in compressed steam refrigerators and thermocompressors on their efficiency

The object of researching: vapors compressor refrigerators and heat pumps plants of different technological application. The purpose - improved calculation and increased effects of vapor compressors for cooling machines and heat pumps on the base of consideration of interconnected influence of thermoliquid irreversible process in the main blocks and parts of refrigerators (RM) and heat pumps (HP). Methods - experiments, math designing; Innovations - the method of consideration of non-isobar process of condensation and evaporation in refrigerates and heat pumps cycles to estimate their cooling and heating benefit has been suggested. The energetic effect of structural complicated diagram for RM and TH and their perceptibility to the stage of irreversible processes has been analyzed. The results - an engineering calculation method for refrigeration plants and heat pumps has been developed and grounded. It's possible to put into practice an ecologically clean energy-saving hot water-supply system on the base of set and grounded diagram solutions of coordination for cooling and heat-pumps plants on the cooling stations. Application - it was used when reconstructing cooling plants in Ukrainian State Company "Kolos". Branch of industry- industrial thermal power engineering.
