摘要： An absorption cycle (110) according to the present invention is configured to operate using: a refrigerant having a global warming potential of less than 1000, and including at least one of an HFO-based refrigerant, an HFC-based refrigerant, and an HCFO-based refrigerant; and an absorbing liquid including at least one compound represented by Formulas (1), (2), and (3): R1—(OCH2CH2)n—OR2 (1) R1—(OCH2CH(CH3))n—OR2 (2) R1COO—(OCH2CH2)n—OR2 (3) where R1 and R2 are each independently a hydrogen atom or an alkyl group having a carbon number of 1 or more and 6 or less, and n is an integer of 1 or more and 6 or less.
