Performance Assessment of a Solar-Assisted, Ground-Coupled Absortion Heat Pump Under Different Scenarios in Summer and Winter Operation
Abstract
This work describes a novel HVAC system consisting in a solar-assisted ground-coupled absorption heat pump. The aim of this work is to analyze, using a TRNSYS simulation program, the influence of different design parameters, such as the area of the solar collectors; the building occupancy and the using schedule, as well as an assessment of the influence of the weather conditions in the energy performance of the installation during winter and summer season. Finally, an annual analysis of the energy transferred by the main elements of the installation (solar collectors, boiler, geothermal heat exchange, generator, condenser, evaporator, radiant floor) under the actual operating conditions was carried out.
