Thermosyphon Assisted Cooling System in Domestic Refrigerator

Performance Analysis of a Domestic Refrigerator

Refrigerator is one of the home appliance utilizing mechanical vapour compression cycle in it process. Performance of the system becomes main issue and many researches are still ongoing to evaluate and improve efficiency of the system. Therefore, this paper presents the development process of refrigerator test rig and performance analysis of a domestic refrigerator. The experiment platform whic...

Inherently Safe Looped Thermosyphon Cooling System for Aircraft Applications using Dielectric Fluid H-Galden

This paper presents experimental results of an inherently safe liquid cooling system. A test rig is operated at Hamburg University of Technology in order to prove the concept and gather first data for electronics cooling in modern civil aircraft. The cooling system uses a dielectric working fluid for the natural circulation in a looped thermosyphon operating in both oneand two-phase mode. First...

Dual-Controlled Indirect Cooling Refrigerator/Freezer Using Two Capillary Tubes and an Air Flow Switching System

The dual~controlled refrigeration system is devised to enhance the energy efficiency and basic performance of an indirect cooling household refrigerator/freezer. In order to alternately serve the fresh food and freezer compartment with a conventional simple refrigeration cycle, two capillary tubes and on/off valves are adopted. The air flow switching system, which is composed of two fans and da...

Artificial Neural Network Involved in the Action of Optimum Mixed Refrigerant (Domestic Refrigerator) (TECHNICAL NOTE)

This analysis principally focuses on the implementation of Radial basis function (RBF) and back propagation (BPA) algorithms for training artificial neural network (ANN) to get the optimum mixture of Hydro fluorocarbon (HFC) and organic compound (Hydrocarbons) for obtaining higher coefficient of Performances (COPs). The thermodynamical properties of mixed refrigerants are observed using REFPROP...
