Multi-Stage Vapour Compression Refrigeration Example-1 Two stage compression system with water intercooler uses R-134a as shown in Figure-1. INNOVATIVE VAPOR-COMPRESSION REFRIGERATION SYSTEMS • The simple vapor-compression refrigeration cycle is the most widely used refrigeration cycle, and it is adequate for most refrigeration applications. Multistage Vapor-Compression Refrigeration Cycle. See our User Agreement and Privacy Policy. The vapor-compression uses a circulating liquid refrigerant as the medium (usually R134a) which absorbs and removes heat from the space to be cooled and subsequently rejects that heat elsewhere.The figure depicts a typical, single-stage vapor-compression system. x�b```b``Y��π ��@��~j�m\��|��?~��S�NU1�g`Hh��!< ��K��Ny 5�IS�q�R� �Ԓ�l��n�� 2�Z��"�K�-Yː4)�E��x.��$�h��@�Vu+�lQ?�|�� "F$H:R��!z��F�Qd?r9�\A&�G��rQ��h��E��]�a�4z�Bg��E#H �*B=��0H�I��p�p�0MxJ$�D1��D, V��ĭ��KĻ�Y�dE�"E��I2��E�B�G��t�4MzN��r!YK� ��?%_&�#��(��0J:EAi��Q�(�()ӔWT6U@��P+��!�~��m��D�e�Դ�!��h�Ӧh/��']B/��ҏӿ�?a0n�hF!��X��8��܌k�c&5S��6�l��Ia�2c�K�M�A�!�E�#��ƒ�d�V��(�k��e��l ��}�}�C�q�9 Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube.
