Improvements on performance of a heat pump water heater system
Heat Pump Water Heater (HPWH) is classified as one renewable energy efficient technology, which could be explained by their environmentally friendly nature with low energy consumption. The Coefficient of Performance (COP) of the HPWH can be influenced by multiple factors: ambient temperature, …

Transient distribution of refrigerant and oil in a residential heat pump water heater system
… oil would affect the characteristics of heat transfer, pressure drop and mass retention in system. In addition, a large amount of retention of oil outside of the compressor might cause insufficient lubrication of the compressor, and eventually lead to compressor failure. The objective of …

A quasi-steady modeling approach of a heat pump water heater system with experimental validation and analysis
In a heat pump water heater system, the dynamic interdependence between the vapor compression system and the water in the storage tank poses a modeling challenge for steady-state refrigeration system models. The aim of this project is to develop a model and methodology for coupling steady-state …
