Fig. 3. Simulation results of the flexible heat pump cycle with a latent heat storage for an evaporating temperature of 0 °C when the condensing temperature varies from 25 to 70 °C.

Fig. 3

a COP improvement αLatent varies as the latent heat storage temperature varies for each given condensing temperature. b The maximum COP improvement increases as the condensing temperature increases. c The corresponding optimal temperature of the latent heat storage varies, increasing with the condensing temperature.
