Title:
ABSORPTION-TYPE REFRIGERATOR
Document Type and Number:
Japanese Patent JP2017048935
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an absorption-type refrigerator in which a two-stage absorption cycle is combined with a single-effect cycle, in which heat is collected from one heat discharge source of about 90°C until reaching a low temperature to supply a cold, a low-pressure regenerator is down-sized, each heat exchanger is flexibly arranged, and the number of solution pumps is optimized.SOLUTION: An absorption-type refrigerator includes: an evaporator; an absorber; a low-pressure regenerator; a high-pressure regenerator; an auxiliary absorber; an auxiliary regenerator; a condenser; and a solution pump. The evaporator and the absorber have a vapor phase communicating to each other, the low-pressure regenerator and the auxiliary absorber have a vapor phase communicating to each other, and the high-pressure regenerator, the auxiliary regenerator, and the condenser have a vapor phase communicating to one another. A solution pipe extending from the absorber to the high-pressure regenerator has a branch part at which a solution pipe extending towards the low-pressure regenerator is connected. A solution pump is provided to a solution pipe extending from the absorber to the branch part. A solution pipe extending from the high-pressure regenerator to the absorber has a confluence part connected to the solution pipe extending from the low-pressure regenerator.SELECTED DRAWING: Figure 1
