Sub-cooling is used to improve the coefficient of performance (COP) of the R&A .
Fig. 1.1- Schematic diagram of Vapour Compression Refrigeration System (2) Condenser: - The function of a condenser is to remove heat from the superheated high pressure refrigerant vapour and to condense the vapour into a sub cooled high pressure liquid. This is accomplished a cooling medium either air or water.A. Vapour Compression Refrigeration System The vapour compression system is the most widely used refrigeration system in practice and its schematic diagram is shown in Fig1. This system adopts vapour compression cycle described in Fig2 on p-h and T-s co-ordinates. This standard cycle constitutes mainly four processes namely:Figure 1: Vapor Compression Test Rig A vapour compression refrigeration system is an improved type of air refrigeration system in which a suitable wo rking substance, termed as refrigerant is used. It condenses and evaporates at temperatures and pressures close to the atmospheric conditions. The refrigerant used does not leave the system but is . Experimental and simulation investigation of the performance and characteristics of different refrigerants and blends of refrigerants is carried out to replace the existing refrigerant R134a for a vapour compression refrigeration system. The performance of VCRS systems was improved by several researchers by introducing the concept of mixing the family of .

An experimental performance study on a vapour compression refrigeration system with the new R290/R600a refrigerant mixture as drop-in replacement was conducted and compared with CFC12 and HFC134a.
The refrigeration system test rig was designed by employing the design approached of Bolaji and Falade [4] who designed, constructed and carried out a performance test . Development of a Refrigeration System Test Rig 39 Fig. 1. Vapour compression refrigeration system schematic and T-s diagram The calculations were performed by assuming steady .test rig operating on vapour compression refrigeration cycle. The system was developed with animated metal sheet while polystyrene was used for absorbing heat generated between the cabinet and the .
Air conditioning and refrigeration have become necessary in modern life, accounting for more than 7.8% of greenhouse gases (GHG) emitted globally. Reducing the environmental impact of these systems is crucial for meeting the global GHG emission targets. Two principal directions must be considered to reduce the environmental impact of air .The Experimental test rig is fabricated by . 11-21 3 4 = experimental cycle of vapour compression refrigeration system equipped with heat exchanger. July - August 2020 Vapor-compression refrigeration systems exploit two fundamental properties of all fluids: (i) The boiling temperature varies with pressure, and (ii) a change in phase (liquid boiling to a vapor and condensing back to a liquid) is accompanied by the absorption or release of heat. . “2L,” “2,” or “3,” ranging from 1 for refrigerants .
