The design includes the use of two-phase ejectors and natural circulation evaporators to improve efficiency and can use both external air and water as heat source/sink. Two units were installed in Italian hotels to provide full energy services in a water/water configuration, or to provide cooling and domestic hot water in an air/water lay-out. After an extensive test campaign, data from the field is collected. This dataset includes necessary field data.
