VACUUM ASSISTED ABSORPTION CHILLER. PART I: MODELING AND SIMULATION
Abstract: A new absorption chiller assisted by a vacuum device has been simulated and characterized through a simulation process. Simulation has been developed for a range of 0.75-10 bars for the evaporation process with a constant ratio between the condensation and evaporation pressure of 10. Simulation has predicted a great improvement of the COP of the absorption chiller when operating at evaporation pressures under atmospheric level, with values of 6.844 for …

Recent Advances to Compare the Performance of Domestic Refrigerator Using New Eco-friendly Refrigerants
Abstract: This paper presents the performance comparison of new eco-friendly refrigerants in domestic refrigerator with respect to energy and exergetic analysis. To make an alternative arrangement of R12 or R134a, and for comparing the performance of new refrigerants some factors and technologies are important which is required to be considered likes their thermodynamics properties, GWP, ODP, energy and exergy analysis, TEWI analysis. In the ongoing work many experimental investigations were made …

Vapor Compression Refrigeration System
Abstract: Refrigeration has been achieved in a variety of methods throughout history, but due to their efficiency anddurability, vapor-compression refrigeration systems (VCRS) have become the favored option. A vapor-compression refrigeration system, in essence, is a system that uses liquid refrigerant in a closed systemthat circulates it through four stages of compression and expansion, transforming it from liquid to vapor.As a result of this change, heat is either absorbed or ejected by …

Fabrication of Air Conditioning Suit
Abstract: A PPE kit is personal protective equipment. PPE (Personal Protective Equipment) is specific clothes or equipment worn by employees to assure themselves against infectious materials. By forming a barricade between the potential infectious material and the health care worker, PPE avoids contact with an infectious agent or body fluid that may contain an infectious agent. An air conditioning is done by using an Ac machine which produce a cooling effect …
