摘要:Abstract(#br)Regenerated air (reverse Brayton) cycle has unique potentials in heat pump applications compared to conventional vapor-compression cycles. To better understand the regenerated air heat pump cycle characteristics, a thermodynamic model with new equivalent parameters w...

摘要:Abstract(#br)In the conventional vapor-compression heat pumps, the heating capacity and the heating load usually vary in opposite directions, which results in a mismatch of the heating capacity and the heating load at off-design conditions. Air (reversed Brayton) cycle is a poten...

摘要:Abstract(#br)This paper compares the overall thermal performance of refrigerant-to-air finned-tube condensers with elliptical and circular tubes. A distributed-parameter model of the circular-tube and the elliptical-tube condensers is developed and the prediction agrees well...

摘要:Abstract(#br)The elliptical tube has long been considered as an alternative of the circular tube in finned-tube heat exchangers (FTHE). Most of the previous studies evaluated the two tube shapes only based on the air-side performance of FTHE, and did not consider any interac...

摘要:Abstract(#br)CO 2 transcritical cycle has been widely applied in commercial refrigeration and heat pump water heating systems. Its cycle COP (coefficient of performance) heavily depends on the high pressure optimization and control. In theory, the optimal high pressure increases ...

摘要:Abstract(#br)DOAS (dedicated outdoor air system) has drawn much attention recently. However, it is quite energy-intensive resulted from the big temperature and/or humidity difference between outdoor air and supply air. This paper proposed a new DOAS with exhaust air heat rec...

摘要:Abstract(#br)The paper presents a dimensionless neural network modeling method for the fin-and-tube refrigerant-to-air condensers which are widely used in air-cooled refrigeration and heat pump systems. The model-based dimensional analysis method is applied to develop the dimensi...

摘要:Abstract(#br)Air source heat pump water heater (ASHPWH) is designed to work under wide operating conditions. Therefore, both the system and components require higher reliability and stability than ordinary heat pump air-conditioning systems. In this paper, a quasi-steady-state sy...

摘要:Abstract(#br)With the increasing applications of CO 2 trans-critical cycles, the design of reciprocating compressors returns to the center stage. Quick design and optimization of a compressor with arbitrary configuration is always a big challenge. This paper presents a new g...
