Title:
ABSORPTION REFRIGERATOR
Document Type and Number:
WIPO Patent Application WO/2018/150516
Kind Code:
A1
Abstract:
This absorption refrigerator is provided with: an evaporator; an absorber; a low-pressure regenerator; a high-pressure regenerator; an auxiliary absorber; an auxiliary regenerator; a condenser; and a solution pump, wherein the evaporator and the absorber are connected with each other at respective gas phase parts, the low-pressure regenerator and the auxiliary absorber are connected with each other at respective gas phase parts, the high-pressure regenerator, the auxiliary regenerator, and the condenser are connected with one another at respective gas phase parts, solution piping laid from the absorber toward the high-pressure regenerator has a branch part, solution piping laid toward the low-pressure regenerator is connected to the branch part, the solution pump is provided to solution piping laid from the absorber to the branch part, and solution piping laid from the high-pressure regenerator toward the absorber has a confluence part connected to solution piping from the low-pressure regenerator. Thus, in the absorption refrigerator that combines a two-stage absorption cycle with a single-effect cycle, cold can be supplied by recovering heat from one exhaust heat source of about 90°C until a low temperature is reached, the low-pressure regenerator can be downsized, each heat exchanger can be freely arranged, the solution pump can be made smaller, and power consumption can be reduced.
