Abstract
Due to the rising demand for high comfort standards and efficient energy use, heat pumps and solar technologies have drawn a great deal of attention as means through which significant energy reductions can be achieved. During the last decade, a number of investigations have been conducted on the design and modelling of different heat pump systems. This paper examines the performance of a solar assisted air source heat pump (ASHP) system for cold climate. The study compares the operation of a stand-alone ASHP against the solar assisted ASHP. The experimental measurements are used to test the performance of the ASHP system in different operating conditions. In addition, using TRNSYS (Transient Systems Simulation) software, simulation models were developed. The simulations using TRNSYS are compared to experimental data. Validation results for system modes of operation are included which demonstrate good conformity between model and experimental performance.
