Development and validation of a reduced order fin-and-tube heat exchanger model
Sarfraz, Omer (2020-05)Vapor compression systems are the most widely used cooling system type in heating, ventilation, and air-conditioning (HVAC) applications. Two of the four basic components of a vapor compression system are heat exchangers, ... -
Development of recommendations for air mixer and sampler design and combinations thereof for performance testing of HVAC equipment
Park, Hyunjin (2023-05)Advances in equipment performance, and the development of variable speed equipment have led to stricter performance testing of HVAC&R equipment, requiring limited tolerances on capacity and efficiency measurements to 5% ... -
Enhanced Vertical Ground Heat Exchanger Model for Whole Building Energy Simulation
Mitchell, Matt Sandy (2019-07)The U.S. Energy Information Agency estimates that buildings consume more than 40% of all energy used in the United States. This includes considering energy used for transportation and heavy industry. As a result, many ... -
Experimentally validated heat exchanger refrigerant charge model and optimization of refrigerant charge for a heat pump
Lee, Abraham Juseok (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. ... -
Predicting and testing the performance of next generation heat exchangers with low-GWP refrigerants
Saleem, Saad (2021-12)Energy efficiency regulations are forcing air conditioning (AC) and heat pump (HP) manufacturers to replace existing high global warming potential (GWP) refrigerants in their systems with more climate friendly alternatives. ...
