dc.description.abstractСьогодні у системах кондиціювання та опалення невеликих приміщень промислових, громадських та житлових об’єктів використання теплових помп (ТП) повітряних split-кондиціонерів стає все розповсюдженішим. Але теплові помпи повітряних split-кондиціонерів належать до енергоємного обладнання, а тому потребують підвищення їх енергоефективності. Тому стає актуальним зменшення енергозатрат під час експлуатації холодильних машин, які працюють в режимі теплової помпи в split-кондиціонерах, що можливе з використанням сучасного методу термодинаміки — ексергетичного. Ексергетичний аналіз дозволяє встановити максимальні термодинамічні можливості системи, визначити втрати ексергії в ній та обґрунтувати рекомендації з вдосконалення окремих її елементів. Для цієї статті використано розроблений авторами ексергетичний метод аналізу роботи одноступеневих хладонових теплових помп split-кондиціонерів. У результаті встановлено універсальну залежність для визначення ексергетичного ККД теплової помпи split-кондиціонера фірми “Mitsubishi Electric” теплопродуктивністю 3200 Вт, яка дає можливість підібрати параметри її роботи з максимальним ексергетичним ККД. Описаний алгоритм отримання такої універсальної залежності можна використати для теплової помпи split-кондиціонера будь-якої фірми та будь-якої теплопродуктивності.
dc.description.abstractToday, in air conditioning and heating systems for small rooms of industrial, public, and residential buildings, the use of heat pumps of air split-conditioners is becoming more common. However, heat pumps of air split-conditioners are energy-intensive equipment, and, therefore, the need to increase their energy efficiency arises. It is important to reduce energy consumption during the refrigeration machines operating in the mode of heat pump in air split-conditioners, which is possible using a modern method of thermodynamics — an exergetic one. Exergetic analysis allows for establishing the maximum thermodynamic capabilities of the system, determining the losses of exergy in it, and substantiating recommendations for improving some of its elements. The exergetic method of analysis of the operation of one-stage steam-compressor freon heat pumps of air split-conditioners developed by the authors is used in this article. As a result, the universal dependence for determining the exergetic output-input ratio (OIR) for the air split-conditioner heat pump by "Mitsubishi Electric" with a heating capacity of 3200 W has been established, which makes it possible to select the parameters of its operation with the maximum exergetic OIR. The described algorithm for obtaining such a universal dependence can be used for heat pump air split-conditioner of any firm and any heating capacity.
