Abstract
Air source heat pump water heaters (ASHPWH) are becoming increasingly popular for saving energy, protecting the environment and security purposes. The water temperature distribution in the tank is an important parameter for an ASHPWH. This paper presented a mathematic model for a cylindrical water tank with a cylindrical condenser as its heat source. The computational fluid dynamics (CFD) software package, FLUENT, was used to study hot water temperature distribution in the tank of the ASHPWH. In addition, the effects of tank dimension and the type of condenser coil on water temperature distribution were discussed. The work of this paper could be used for the optimization of tank and condenser coil designs.
