Résumé

In Osaka, Japan, a combined hot/chilled water thermal storage air-source heat pump system and ice storage chiller system are being used for district heating and cooling. These two systems are linked to create a larger temperature difference between the supplied and returned chilled water. In order to reduce the system energy consumption, one air-source heat pump extracts ambient heat through a heating tower and the second heat pump operates in heat recovery mode while also producing chilled water. An ice thermal storage system contributes to load balancing by using night-time electricity. The system has been in operation since november 1992 and supplies cold and heat to two buildings. Another building will be added in the future.
