dc.description.abstractThe paper investigates the performance effect of outdoor temperature and relative humidity on ASHP performance above frosting conditions, with the developed mathematical model. The model results are validated with the experimental data available in literature, of four ASHPs in the 2.7 kW 5.8 kW capacity range. 4 kW capacity ASHP is taken as reference. Constant heating (CH), constant work (CW) and variable heating (VH) modes are determined as operating modes. The model results reveal that relative humidity is a performance enhancing factor above frosting conditions. In VH mode, which is the most realistic operating mode for residences, raise in outdoor temperature from 7 degrees C to 14 degrees C increases the COP value by 30%, and raise in the relative humidity from 0.6 to 1.0 provides an additional 5% COP increase. In CH and CW modes, the contribution of relative humidity to performance increases with temperature, up to 10.7% and 6.4%, respectively. Correlations giving the COP change rate with respect to ambient temperature and relative humidity are derived with higher than 0.9839 R2 values for dry and humid conditions of the CH, CW and VH operating modes. These correlations can be useful for researchers who intends to analyze ASHP performance based on ambient conditions.
