Single-and double-effect absorption refrigerator

摘要

A single-and double-effect absorption refrigerator comprising a drum including both a preliminary low-temperature regenerator having a low-temperature heat source and a condenser, a piping for low-concentration liquid absorbent extending from an absorber to the preliminary low-temperature regenerator through the pump for low-concentration liquid absorbent, a piping for intermediate-concentration liquid absorbent having a pump for intermediate-concentration liquid absorbent and extending from the preliminary low-temperature regenerator to a high-temperature regenerator, and a pipe for liquid absorbent connecting a part of the piping for intermediate-concentration liquid absorbent provided on a drawing side of the pump for intermediate-concentration liquid absorbent to a pipe for high-concentration liquid absorbent extending from a low-temperature regenerator to a low-temperature heat exchanger.
