Abstract

The invention provides an ammonia water absorption-compression refrigeration / heat pump system and a heat exchange method. Ammonia water working medium absorption-compression refrigeration / heat pump system, including the first generator, compressor, condenser and absorber, the first generator, compressor, condenser and absorber constitute the main circuit, ammonia water working medium absorption-compression The type refrigeration / heat pump system also includes: a first gas-liquid separator having a first inlet, a first gas separator outlet and a first liquid separator outlet, arranged on the main circuit and between the first generator and the condenser , and the first inlet is connected to the first generator, and the first gas separation outlet is connected to the compressor. The ammonia water absorption-compression refrigeration / heat pump system has the characteristics of both absorption and compression refrigeration / heat pump systems, and has a concentration adjustment mechanism to adjust the concentration of ammonia water working medium in the system to meet the needs of different working conditions.

Description

technical field [0001] The invention relates to the field of refrigeration, in particular to an ammonia water absorption-compression refrigeration / heat pump system and a heat exchange method. Background technique [0002] Ammonia molecules are similar to water molecules in structure and physical properties. In addition to certain toxicity and corrosiveness, as a natural working medium, it has no ozone layer damage and greenhouse effect. In the field of steam power generation, there have been many industrial application examples of the Kalina cycle for many years, that is, using the steam of ammonia solution instead of water vapor as the circulating working medium (ie Rankine cycle) to generate electricity. There are two main advantages. One is that the ammonia water solution is a binary non-azeotropic refrigerant, which has a higher heat exchange efficiency than pure water vapor; Improve cycle efficiency under different working conditions. The Kalina cycle can increase pow...
