Résumé

The energy outlook of a supermarket in Stockholm, as well as its refrigeration cycle efficiency are investigated based on field measurements. The refrigeration unit of the system is a CO2 trans-critical booster system with heat recovery, air conditioning, and geothermal storage integration. Field data are analyzed from 1st of January 2019 until the end of the same year. Based on the field measurements, low, medium temperature level, air conditioning cooling and space heating demands, as well as COP’s are calculated, for thirty-minute intervals, averaged to different ambient temperatures. The same method is used for calculating the thermal loads from the ground. The results show energy efficiency improvement comparing to previous studies, which originates from several factors such as: changes in the system design (e.g. three stage expansion), higher total efficiency of compressors, zero or low internal superheat at the three evaporation temperature levels resulting in higher evaporation temperatures. The COP for the medium temperature level reaches 8,5 and 7,5 for space heating.
