PERFORMANCE ANALYSIS OF A CASCADE HIGH-TEMPERATURE HEAT PUMP USED IN A SINGLE-FAMILY DWELLING IN BELGIUM


This paper is devoted to the performance analysis of a very high-temperature airsource heat pump which uses a newly-developed cascade cycle. The heat pump has been installed in a non-insulated house in Belgium in August 2013 and is used for space heating in combination with high-temperature radiators, or for domestic hot water production. The heat
pump has been equipped for detailed performance monitoring. Firstly, the results of the monitoring campaign are presented. They show a complex behavior of the heat pump but
are very promising. Secondly, the behavior of the heat pump used for space heating is modeled to determine the best mode to use depending on the source and sink temperatures.
The results show good agreement with the manufacturer’s data.
