dc.description.abstractIn this study, energy and exergy analyzes were carried out to heat an experimental room with 28 square meter area by a surface water source heat pump (SWSHP) in the heating season, where placed in next to a river source (Arac stream) in Karabuk University. The system had a frequency inverter to change the compressor speed and the experiment was started at 35 Hz. in winter condition and completed when the indoor temperature reached 25.degrees C. While the COP value of the system was calculated as 2.58 on average, the highest exergy destruction was determined as 0.6 kW in the compressor in terms of the exergy analysis. The average exergy destructions were determined as 0.125 kW for the condenser, 0.152 kW for the expansion valve, 0.14 kW for the evaporator and fan coil system, and 0.06 kW for the water source heat exchanger. Exergy efficiencies were 60% for the compressor, 75% for the condenser, 85% for the expansion valve, 25% for the evaporator, 63% for the fan coil system and 8% for the water source heat exchanger. As a result of the study, it has been determined that the surface water source heat pump system works successfully in Karabuk province conditions.en_US
