PROBLEM TO BE SOLVED: To ensure reduction of electric power consumption. SOLUTION: A regenerative air conditioner comprises refrigerant piping in which an outdoor unit, a regenerative unit and one or more outdoor unit are connected so as to utilize heat, which has been stored during night time, for day time air conditioning. Specifically, the air conditioner comprises a first regenerative unit 2a for passing refrigerant which has been transferred from an outdoor unit 1 to indoor units 3a, 3b during the operation of a compressor 4, and comprises a second regenerative unit 2b for passing the refrigerant which is returning to a liquid refrigerant pump 16 from the indoor units 3a, 3b during the operation of the pump 1. The individual regenerative units 2a, 2b are connected parallel between the outdoor unit 1 and the indoor units 3a, 3b.
