Abstract
The utility model discloses a single-stage ammonia water absorption refrigerator. No fractional condenser is arranged in a system. The top of a rectifying column of a generator is connected to the top of a condenser through pipelines, an outlet pipeline at the lower end of the condenser sequentially penetrates through a gas-liquid separator, a subcooler and an evaporator to be connected to the top of the gas-liquid separator, the bottom end of the gas-liquid separator is connected to the top of the rectifying column of the generator through a pipeline, and a solution pump is installed on the pipeline. After aqueous solution of ammonia in the gas-liquid separator at the outlet position of the evaporator exchanges heat with liquid ammonia from the condenser, the aqueous solution of ammonia is pressurized by the solution pump and directly sprayed from the top of the rectifying column, and exchanges heat and mass with rising steam in the rectifying column of the generator, thereby not only ensuring concentration of ammonia steam at the outlet of the rectifying column, but also recycling rectification heat, avoiding effect on inside temperature of the rectifying column due to changes of outside temperature and enabling stability of system operation to be greatly improved. The single-stage ammonia water absorption refrigerator simplifies the cooling water system, reduces usage amount of cooling water and is beneficial for saving energy.
