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. ... -
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 ... -
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 ...
