Device for specifying the solution concentration in an absorption cooling machine comprises two identical sections located between abosrber~s solution pump and solution heat exchanger and solution heat exchanger and choke valve
Device for specifying the solution concentration in an absorption cooling machine comprises two identical sections located between abosrber~s solution pump and solution heat exchanger and solution heat exchanger and choke valve
The device comprises an absorber (24), a solution pump (12), a choke valve (25), a solution heat exchanger (26), a discharger (27), a condenser (28), a further choke valve (29) and a vaporizer (30). The device is made up of two identical sections (I and II) with a measuring pipes (2, 23) in which conducting electrodes (3, 4, 13, 14), a direct current source (5, 15) and a current and temperature apparatus (6, 16, 7, 17). The first section (I) is arranged between the absorber~s solution pump and the solution heat exchanger and the second section (II) is located between the solution heat exchanger and the choke valve and absorber. The electrodes are positioned in a section of the measuring pipes of the first section parallel to a main pipe connection (1) in which the coolant solution flows, as well as being positioned in section of the measuring pipes of the second section parallel to a main pipe connection (22).
