Показано, что: а) системы кондиционирования воздуха (СКВ) помещений в судах различного типа
функционируют в сложных эксплуатационных условиях; б) оптимизация энергопотребления, рационализация процессов
управления, проектирования и эксплуатации судовых СКВ невозможны без решения задач моделирования отдельных ее
элементов (калориферов, теплообменных аппаратов и других). Проведен анализ литературных источников, посвященных
методам и принципам моделирования отдельных элементов и СКВ. Установлено, что наиболее эффективным методом
имитационного моделирования СКВ является структурный метод в объектно-ориентированной среде, с использованием
передаточных функций с сосредоточенными или распределенными параметрами, при необходимости - дробных степеней.
Shown a) that rooms’ air condition system (ACS) in different ship types function in hard service conditions such as substantial changes in ambient temperature, humidity, dustiness, pressure; b) that ships’ ACS are various in technical realization such as comfortable and technical, centralized, self-contained, combined, one-, two- and duct-free ACS; c) that optimization of the energy consumption mode, rationalization of control process, automation, design and service ships’ ACS impossible without decision specific tasks of modeling its separate components (calorifiers, heat -exchange apparatus, compressors, air ducts and others). The analysis of well known literature sources which dedicated methods and modeling principals of separate elements and ACS in common and modeling of ship’s ACS and industrial cold-storage plants has done. It was determined that the most effective method of object-oriented modeling of ship rooms ACS is the structure method in object-orientated fields (Маtlab, LabVIEW, VisSim and others), with use of the transfer-functions (TF) with focused or distributed parameters if necessary assisted by fractional degree TF inclusive of the transport delay, use of non-linear links and approximation spreadsheets.
