Abstract First operation data of a test site with four parallelly operated natural gas driven absorption heat pumps (GAHP) using NH3/H20 as working pair and air as an environmental heat source will be presented. Waste heat of an indoor pool hall is used to raise the heat source temperature. The influence of the resulting high ambient air temperatures - along with additional necessary fans - on the system efficiency will be investigated. In this paper gas utilization efficiencies, auxiliary energy factors and primary energy ratios for high air inlet temperatures above 17 °C will be presented and compared to a system using ambient air as heat source. In addition the influence of the load behaviour on the gas utilization efficiency, auxiliary energy factors and primary energy ratios will be revealed.
