Summary

Innovative technologies are always matter of study. In this work, an experimental performance analysis of an ammonia-water condensing gas absorption heat pump was conducted. This heat pump has a nominal heating capacity of 18,9 kW and it is designed for domestic hot water and space heating. The tests were carried out in a climatic chamber in order to emulate different outdoor ambient conditions regarding temperature and humidity. Different tests conditions were imposed based on a combination of the EN 12309 requirements and typical weather data for Belgium. Measures of gas consumption, electrical consumption, mass flow rates and temperatures were collected to compute performance indicators. The experimental results showed a COP that varies between 0.86 and 1.45 for different delivery water temperatures and ambient conditions. Also, it was observed than the humidity could have a positive or negative impact on the COP.
