Performance evaluation and validation of a novel heat pump water heater with rotary compressor and D-shaped condenser coils.

Number: pap. n. 584

Summary

This paper presents the model of the heat pump water heater that has two interdependent parts: water in the storage tank of a heat pump water heater and the steady-state vapor compression system. System performance is modelled by Engineering Equation Solver (EES) while computational fluid dynamics (CFD) is used for the water tank. These models are linked to simulate the performance in the transient, warm-up period. The iterations between the EES-CFD linked model exchange the data though the interface of the water and tank wall until obtaining the matched solutions for both models. This EES-CFD linked model is found to be in good agreement with the experimental results conducted in the same activity and can predict the temperature distribution of the vapor compression system and transient behavior of the thermal storage tank.
