   <abstract xml:lang="ru">
    <p>В целях повышения эффективности эксплуатации воздушного теплового насоса актуальным является анализ термодинамических параметров цикла парокомпрессионного фреонового контура. Для того чтобы оценить все термодинамические процессы в теплохолодильной системе воздушного теплового насоса и произвести расчеты, как правило, используют тепловые диаграммы, разрабатываемые производителями. Авторы предлагают использовать для ориентировочного расчета парокомпрессионного фреонового контура таблицы на линии насыщения и линии перегретого пара рабочего хладагента. В результате расчета теоретического парокомпрессионного цикла были получены значения тепловой энергии, изымаемой рабочим телом в процессе его непрерывного фазового превращения: кипения, испарения, конденсации, которые определялись по точкам состояния энтальпии на соответствующих участках работы элементов ВТН (испаритель, компрессор, конденсатор). Расчеты показали, что при создании тепловой мощности на выходе теплового насоса определяющим параметром является фазовое превращение скрытой теплоты парообразования при кипении и конденсации рабочего тела в замкнутой системе компрессионного цикла.</p>

    <p>To improve the efficiency of using an air heat pump (AHP), it is important to analyze the thermodynamic parameters of the vapor-compression freon loop cycle. To evaluate all thermodynamic processes in the heat recovery system of the air heat pump and to make calculations, experts frequently use heat charts developed by the manufacturers. The authors propose to use tables on saturation line and superheated vapor line of working refrigerant for approximate calculation of vapor-compression freon loop. As a result of calculation of a theoretical vapor -compression cycle, the authors obtained heat energy values taken by the working body during its continuous phase change: boiling, evaporation, condensation, which were determined by the enthalpy state points at the corresponding sections of operation of AHP elements (evaporator, compressor, condenser). Calculations showed that at creating thermal power at the heat pump output, its determining parameter is the phase change of latent heat of vaporization at boiling and condensation of working body in the closed compression cycle system.</p>
