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)Transcritical CO 2 cycle has been widely investigated fundamentally and practically. However, transition between subcritical and transcritical CO 2 cycles has not yet been well studied. In this work, temperature at maximum constant-pressure specific heat (pseudocriti...

摘要:Abstract(#br)This paper presents a new approach of combining response surface methodology and neural network for performance evaluation of fin-and-tube air-cooled condensers which are widely used in refrigeration, air-conditioning and heat pump systems. Box–Behnken design (B...

摘要:Abstract(#br)As the refrigerant flow inside the capillary tubes is accompanied with phase change, non-equilibrium between two phases, and critical two-phase flow, capillary tube modeling is not as simple as its simple geometry. For the convenience of engineering applications, man...

摘要:Abstract(#br)This paper presents a new hybrid steady-state modeling approach for air-conditioning systems. At the system level, it follows the first principles to keep the conservation of mass, energy, and momentum, respectively. At the component level, the physics-based componen...

摘要:Abstract(#br)The multi-zone model is widely used in evaporator and condenser modeling. The basic two-zone evaporator model and three-zone condenser model might reduce to one-zone or two-zone model depending on the operating conditions. In the traditional multi-zone models, logic ...
