Abstract
To establish the patterns of heat-mass exchange in systems, devices and heat recovery plants using heat pump units, to develop effective solutions for their use in this aspect of the study: analyzed the state of energy conservation and secondary efficiency electric and heat generation on low-boiling working substances. Analysis of the issue; mathematical modeling with the definition of reasonable parameters and the study of energy efficiency of steam and gas mixtures and the possibility of generating heat, electricity; determination of design parameters and parameters of contact heat-mass exchange in the contact device on the basis of ": chamber with atomizers" and their influence on efficiency of work of heat utilization systems, devices and installations with use, the equipment of electric and heat generation on low boiling working substances. Scientific novelty. analysis and mathematical modeling obtained a graphical relationship between the transformation coefficient of the heat pump 3.5-6.5 in the range of coolant parameters - temperature 5-30 (source of secondary energy resources), applied to the developed energy-saving and environmentally friendly safe technology of heat utilization of processes of wet quenching of coke and wet granulation of metallurgical slags and other available sources, including mine waters represented in Ukraine and Kryvyi Rih region . Development of recommendations for the introduction of heat pump installations: inspection and feasibility study of systems, devices and installations for heat utilization of heat and power and electric and heat generation in low-boiling working substances; development of recommendations for their application. Covered in research on "Substantiation of parameters of heat utilization systems of heat power equipment" (state registration number RK№ 0116U001825) and in the scientific work "Heat pumps in the industrial and municipal spheres of Ukraine" (headed by VV Surtaev). The presented scientific and practical results in the form of a graphical dependence for determining the transformation coefficient of the heat pump installation in the range of coolant parameters (sources of secondary energy resources).
