Replication data for : MultiPACK project_An integrated CO2 unit for heating, cooling and DHW installed in a hotel-Data from the field.

This dataset provides data for a new heat pump unit intended to provide heating, cooling and hot water to a hotel and using CO2 as the working fluid. The heat pump was installed in mid-2018 in a hotel located in a touristic area in North Italy and open nearly all over the year. The unit can benefit from groundwater as a heat source or heat sink. The heat pump features a two-phase multi-ejector as an expansion device. An original two-evaporator layout is implemented, where the first one is gravity driven and the second one is ejector driven. It is fully equipped with measurement instruments, data acquisition system and cloud data storage developed and tailored for the unit. The unit was developed, instrumented, installed and monitored within the H2020 MultiPACK the project, which aims at building confidence in integrated heating, ventilation, air conditioning and refrigeration packages based on CO2 technology in high energy-demanding buildings. In this dataset, operational parameters and performance data will be presented, related to winter season, thus to heating and domestic hot water service.

本数据集为一款以二氧化碳（CO₂）为工质的新型热泵机组提供相关数据，该机组可为酒店提供供暖、制冷与生活热水服务。该热泵机组于2018年中期安装在意大利北部旅游区的一家全年近乎无休的酒店内。该机组可利用地下水作为热源或热汇，核心结构采用两相多喷射器作为膨胀装置，并搭载原创性双蒸发器布局：第一蒸发器由重力驱动，第二蒸发器由喷射器驱动。机组配备了为其定制开发的全套测量仪器、数据采集系统与云端数据存储装置。该机组是在欧盟H2020框架下的MultiPACK项目中完成开发、仪表配置、安装与监测的，该项目旨在为高能耗建筑中基于二氧化碳技术的集成式供暖、通风、空调与制冷套装系统树立应用信心。本数据集将呈现该机组在冬季时段（即供暖与生活热水服务工况下）的运行参数与性能数据。
