Labay V. Exergetic Ground and Increase of Energy Efficiency of Work of Refrigeration Machines for Cooling of Air

Exergetic ground and increase of energy efficiency of work of refrigeration machines for split-conditioners are fulfilled and a new method is offered them to the exergetic analysis, which is adjusted for comprehensive thermodynamics research of process of work of these refrigeration machines. The research computer program of exergetic analysis of process of work of refrigeration machines of split-conditioners is created for finding out of influence of different factors, which determine the process of work of these refrigeration machines, on exergetic output-input ratio and technical descriptions of split-conditioners and loss of exergy in their elements. Universal dependences are got for determination of exergetic output-input ratio and losses of exergy in the separate elements of refrigeration machines of split-conditioners and effective energy saving their external environments are offered. The method of increase of energy saving of local autonomous conditioners, protected the patent of Ukraine on an useful model, is offered, by determination of effective energy saving correlations by the charges of air on evaporator and condenser of refrigeration machine, which gives high exergetic output-input ratio relatively. Suggestions are developed from perfection of work of elements of refrigeration machines of split-conditioners, which influence on diminishing of losses of exergy in them and general increase of exergetic output-input ratio of conditioner.
