Компрессором 1 отсасывают парообразный хладагент низкого давлени  и сжимают до высокого давлени , затем конденсируют в конденсаторе 2, Из конденсатора 2 жидкий хладагент высокого давлени  направл ют в эжектор 3, где за счет энергии хладагента высокого давлени  подсасывают жидкий хладагент низкого давлени  из отделител  7. Смесь обоих потоков подают в плиточные морозильные аппараты 4 - 6, включение которых осуществл ют последовательно с временным смещением, равным отношению продолжительности цикла замораживани  продукта в одном морозильном аппарате к числу всех аппаратов. 1 ил. с SS (ЛThe invention relates to refrigeration. The purpose of the invention is to increase the efficiency of the method. A low-pressure refrigerant is sucked off by compressor 1 and compressed to high pressure, then condensed in condenser 2. From condenser 2, high-pressure liquid refrigerant is sent to ejector 3, where due to high-pressure refrigerant energy, liquid low-pressure refrigerant is sucked from separator 7. Both mixtures flows are fed to plate freezers 4-6, which are switched on sequentially with a time offset equal to the ratio of the duration of the product freezing cycle in one m the freezing apparatus to the number of all apparatuses. 1 il. with SS (L
