example 1
[0061] In this example, the low-temperature waste heat at 100°C is elevated to saturated steam at a temperature of 185°C. This example uses 32°C cooling water to cool the condenser and absorbent crystallizer.
example 2
[0063] In this example, the low-temperature waste heat at 75°C is elevated to saturated steam at a temperature of 150°C. This example uses 17°C cooling water to cool the condenser and absorbent crystallizer.
example 3
[0065] In this example, the low-temperature waste heat of 90°C is raised to saturated steam with a temperature of 170°C. In this example, the cooling water at 32°C is used to cool the condenser, and the cold generated by the vapor compression refrigeration cycle is used to cool the absorbent crystallizer.

The invention relates to an absorbent solution circulating system and a method. The absorbent solution consists of absorbent and working substance; and the absorbent solution circulating system comprises a generator, an absorber, an absorbent crystallizer and an automatic absorbent solution heat exchanger. The absorbent crystallizer is used for cooling absorbent solution from the generator and / or absorbent solution from the absorber to form crystallized absorbent solution and absorbent crystals, the crystallized absorbent solution is delivered to the generator, and the absorbent crystals are delivered to the absorber; and the automatic absorbent solution heat exchanger is used for exchanging heat with the crystallized absorbent solution and / or absorbent crystals with the absorbent solution from the generator and / or the absorbent solution from the absorber. The system can achieve circulation of the absorbent solution between the generator and the absorber in the circulation of an absorption heat pump, so as to improve grade of cold or heat outwards output by the circulation of the absorption heat pump and efficiency.
Description
technical field [0001] The invention relates to a circulation technology in the field of thermal energy engineering, in particular to an absorption solution circulation system and circulation method for absorption heat pump circulation. Background technique [0002] see figure 1 As shown, the existing absorption heat pump cycle system uses the characteristic that the absorption solution can precipitate the vapor of the low boiling point component under certain conditions, and can strongly absorb the vapor of the low boiling point component under another condition to complete the heat pump cycle. At present, two-component solutions are mostly used as the absorption solution in absorption refrigerators. It is customary to call the low-boiling point component as the working medium, and the high-boiling point component as the absorbent. . The existing absorption heat pump circulation system mainly includes: a generator 101 with a built-in heat exchanger 110, a condenser 102 wi...
