dc.description.abstractРозроблено математичну модель системи кондиціювання повітря, яка ґрунтується на аналізі термоекономічних показників енергоефективності та вирішена в комплексі: визначення оптимальних параметрів; з врахуванням нестаціонарних теплоприпливів та визначення оптимального пристрою з оптимізації режимів роботи холодильної системи. При проектуванні системи кондиціювання повітря проведений термоекономний аналіз створюваного об’єкта, вирішуючи актуальну задачу енергозбереження з урахуванням зміни тарифів на електроенергію. Розроблена термоекономічна модель холодильної установки системи кондиціювання повітря з визначенням ексергетичних показників і ексергетичних втрат, як складових критерію термодинамічної ефективності енергетичних систем, що забезпечують мінімум приведених витрат. Аналіз моделі дав змогу отримати аналітичне рішення, на підставі якого визначаються оптимальні умови проектування цієї системи кондиціювання і режими її експлуатації.
dc.description.abstractThe mathematical model of the air conditioning system has been developed. It is based on the analysis of thermoeconomic energy efficiency indicators and it is solved in a complex way: by defining the optimal parameters taking into account the non-stationary heat of the tides and by determining the optimal device for optimizing the operating modes of the refrigeration system. When designing an air-conditioning system, a thermoeconomic analysis was made for an object being created. An important problem of energy saving was solved during the design with taking into account the changes in electricity tariffs. The thermoeconomic model of the refrigeration unit of the air conditioning system with the definition of exergetic indices and exergic losses has been developed. These indices and losses are components of the thermodynamic efficiency criterion for energy systems that provide a minimum of reduced costs. Analysis of the model allowed obtaining an analytical decision, on the basis of which we can determine the optimal conditions for designing this air conditioning system and its operating modes.
