FIELD: engineering of steam compression systems and heat exchangers. ^ SUBSTANCE: reversible steam compression system has compressor, internal heat exchanger, expanding device and external heat exchanger, connected by pipelines in working connection for forming of a single system. Internal and external heat exchangers are mounted in main contour. Compressor and expanding device are mounted in sub-contours, connected to main contour by means of flow switch devices for making it possible to switch system from cooling mode to heating mode. Reversible heat exchanger for liquid coolant, in particular, for carbon dioxide, in steam compression system contains several mutually interconnected sections, made with possible serial passage of air through them, having coolant contour, and is connected to mutually connected first and second sections. Flow of liquid coolant is witched from heating mode to cooling mode by means of flow switching devices, mounted in appropriate sections. ^ EFFECT: improved efficiency. ^ 2 cl, 46 dwg |
