Modeling of vertical ground loop heat exchangers for ground source heat pump systems
(1999-12)
The ability to predict both the long-term and short-term behavior of ground loop
heat exchangers is critical to the design and energy analysis of ground source heat pump
systems. For detailed analysis and accurate ...
Experimentally validated heat exchanger refrigerant charge model and optimization of refrigerant charge for a heat pump
(2023-05)
Refrigerant charge affects the efficiency, capacity, and reliability of a heat pump, and incorrect charge can lead to increased energy consumption and decreased performance as well as potential damage to the system. ...
Study of frost growth on heat exchangers used as outdoor coils in air source heat pump systems
(2011-05)
Scope and Method of Study: During winter heating operation, the outdoor coil of a heat pump acts as an evaporator and when the ambient temperature is near freezing, the moisture in the atmospheric air freezes on the coil ...
