چکیده
Abstract Linear compressors are advantageous in terms of miniaturization, high efficiency, and continuous operation without a crank mechanism. The drop-in replacement for R134a domestic refrigerators is R1234yf. This study aims to investigate the linear compressor thermodynamic performance vapour compression system with R1234yf by modelling measuring key parameters such as pressure-volume (P-V) diagram, refrigerant distribution, mass flow rate, volumetric cooling capacity, coefficient (COP). Results show that at 40 °C condenser temperature 2 pressure ratio, achieved maximum 299.1 W which gives 4.12 COP. analysis calculations good agreement results experimental measurements, verifying accuracy model.

This paper investigates the simulation of a hybrid desalination system composed of multi-effect evaporation with thermal vapour compression desalination (METVC) and reverse osmosis (RO) plant. The hybrid desalination system is also integrated with a gas turbine power plant through a heat recovery steam generator (HRSG). First, a comprehensive Thermodynamic model for HRSG, METVC, and RO are deve...
متن کاملModelling and Simulation of the Dynamics of Cross Vane Expander-Compressor Unit for Vapour Compression Cycle
The Cross Vane mechanism was recently invented and employed in the design and development of an expandercompressor unit, named Cross Vane expander-compressor or CVEC in short. This device replaces the compressor and expansion valve of a conventional vapour compression cycle, and improves the energy efficiency of the system. Theoretical models which include geometrical, thermodynamics, mass flow...
متن کاملIntroduction of the Novel Cross Vane Expander-Compressor Unit for Vapour Compression Cycle
A new type of expander-compressor system called Cross Vane expander-compressor (CVEC) was introduced. This device replaces the expansion valve and compressor in conventional refrigeration systems to reduce the energy consumption and improve the coefficient of performance (COP) of the system. As opposed to many expander-compressor systems in the literature, whereby a separated expander is couple...
متن کاملSolving a System of Linear Equations by Homotopy Analysis Method
In this paper, an efficient algorithm for solving a system of linear equations based on the homotopy analysis method is presented. The proposed method is compared with the classical Jacobi iterative method, and the convergence analysis is discussed. Finally, two numerical examples are presented to show the effectiveness of the proposed method.
