<p>An apparatus and method for controlling the use of carbon dioxide in cleaning fabrics are disclosed. The components include a distillation vessel (30), a compressor (5), a warm-up vessel (4), a cleaning chamber (1), a condenser (8), and a carbon dioxide storage tank (3). A reclaim mode of use enables the efficient operation of the apparatus. The reclaim mode recovers most of the carbon dioxide gas remaining in the cleaning chamber (1). There are three steps of the reclaim mode: in the first step the compressor (5) pumps the gaseous carbon dioxide in two parallel stages from the cleaning chamber (1) to the condenser (8); in the second step the compressor (5) pumps the gaseous carbon dioxide through the warm-up vessel (4) and back to the cleaning chamber (1); and in the third step two stages of compression are utilized to remove gaseous carbon dioxide from the cleaning chamber (1) and pump it to the condenser (8).</p> |
