Description 60-68
Heat pumps are devices those allow to use the energy available in nature but cannot be used because of its low
temperature. By raising its temperature, heat pumps do this with a cooling cycle similar to that of air conditioners. This
study presents the performance analysis of an in-room heating system during mushroom compost fermentation using a heat
recovery device with an air source heat pump, which is a type of heat pump. The study was carried out by setting up
experimental equipment and providing measurement-based parameters in the university laboratory. The performance
analysis of the system was calculated by considering all system elements (compressor, condenser, evaporator, expansion
valve etc.) and the results were evaluated numerically. Performance analysis was made according to whether a heat pump is
used in the system. Based on the results obtained by these calculations, when heat recovery device is added to the system,
the work done by the compressor, loss of exergy, exergy balance and efficiency decrease. While the exergy balance of the
condenser decreases, its efficiency increases. Also, while the exergy balance of the expansion valve increase, its efficiency
decreases. Overall, the efficiency of the device increases.
