Replication Data for: The MultiPACK project: installation and monitoring of integrated heat pump systems for high energy consumption buildings.

This dataset includes the data for two heat pump systems installed in the hotels in Italy within the project MultiPACK.The heat pump is installed in a hotel located in a tourist area in North Italy. It is intended to provide heating, cooling and hot water to a hotel, which is open nearly all over the year.The unit can benefit from groundwater as the heat source or heat sink. The heat pump features a two-phase multi ejector as an expansion device, able to utilise expansion work. An original two-evaporator layout is implemented, where the first one is gravity driven and the second one is ejector driven.
