Transient Characteristics of a Single-Effect Absorption Refrigeration Cycle
This paper deals with a lumped-parameter dynamic simulation of a single-effect LiBr-H2O absorption chiller. In many studies the thermodynamic properties of LiBr-H2O solution were taken from some approximate relations causing the results to be somewhat inaccurate. These relations were used to solve simultaneous differential equations involving the continuity of species constituting the LiBr-H2O ...
متن کاملOn the Optimal Frequency and Timing of Control Points in a Project’s Life Cycle
The dynamic nature of projects and the fact that they are carried out in changing environments, justify the need for their periodic monitoring and control. Collection of information about the performance of projects at control points costs money. The corrective actions that may need to be taken to bring the project in line with the plan also costs money. On the other hand, penalties are usually...

In this thesis, we present a dynamical systems approach to adaptive controllers for locomotion control. The approach is based on a rigorous mathematical framework using nonlinear dynamical systems and is inspired by theories of selforganization. Nonlinear dynamical systems such as coupled oscillators are an interesting approach for the on-line generation of trajectories for robots with many deg...
متن کاملDynamical modeling and thermo-economic optimization of a cold room assisted vapor-compression refrigeration cycle
A cold room assisted vapor-compression refrigeration cycle is dynamically modeled in a year and optimized. Total annual cost (TACO) and coefficient of performance (COP) are selected as two objective functions. Both cold room and refrigeration cycle parameters are considered as design variables. Moreover, three working fluids included R22, R134a and R407c are examined. The optimum Pareto front r...
متن کاملFuture of the Refrigeration Cycle with Expander
The refrigeration cycle with the thro~tling device has moe work power consumption and less refrigeration capacity than tha~ with the expander. It is S':Jggested that substituting the expander for the throttling device in the refrigeration cycle should be the efficient way for saving the energy of the refrigeration system. Up to now, the design and ~anufacturing of the two-phase expander seems t...
