Experimentations remain endowed for examining effect of HR12 refrigerant on system accomplishment with monitoring in terms of COP and TR. Temperature and pressure got measured by different temperature and pressure gauges mounted at several predetermined locations. Additionally, power consumption by refrigeration system also got measured from the installed energy meter readings. Altogether, it summarizes the tabular inscriptions of the variations of COPth, COPact and COPrel with TR for HR12 refrigerant. Besides, it also demonstrates the graphical representation of the corresponding variations of COPth, COPact and COPrel with TR for HR12 refrigerant. As expected, it stands observed (from both the stated table and figure) that both COPth and COPact increase with TR, however, the COPrel decreases with the same for said HR12 refrigerant. Furthermore, the stated variations of COPth, COPact and COPrel with TR remain observed as approximately linear, independently. That’s why, both COPth and COPact stand directly proportional to TR, however, the COPrel stands inversely proportional to the same owing to almost linear relationship between the COPth, COPact and COPrel with TR, separately.

Furthermore, the stated variations of COPth, COPact and COPrel with TR remain observed as approximately linear, independently. That’s why, both COPth and COPact stay directly proportional to TR, however, the COPrel stays inversely proportional to the same because of approximately linear relationship between the COPth, COPact and COPrel with TR, individually. Additionally, COPact decreases with the increase of Wi/p for both R12 and HR12 refrigerants. However, Qext increases with Wi/p for both R12 and HR12 refrigerants.

A remote area power supply using cold thermal storage and wind as the energy source is proposed. The primary objective is to provide a renewable energy remote area power supply with cheaper and more robust storage than lead-acid batteries. The proposal amalgamates a vapour compression refrigeration system with a Rankine cycle engine, both using the same working fluid. A tank of freezing brine acts as the condenser in the Rankine cycle and as the evaporator in the refrigeration cycle but also provides the “energy storage”. Analysis of the system indicates that it is practical and that its performance is comparable with existing battery based systems.

Nozzle Inlet

This experimental investigation exemplifies the design and testing of diffuser at compressor inlet and nozzle at condenser outlet in vapour compression refrigeration system with the help of R134a refrigerant. The diffuser with divergence angle of 12°,14° and the nozzle with convergent angle 12°,14° are designed for same inlet and outlet diameters. Initially diffusers are tested at compressor inlet diffuser is used with inlet diameter equal to exit tube diameter of evaporator and outlet tube diameter is equal to suction tube diameter of the compressor. Diffuser helps to increases the pressure of the refrigerant before entering the compressor it will be helps to reduces the compression work and achieve higher performance of the vapour compression refrigeration system. Then nozzles are testing at condenser outlet, whereas nozzle inlet diameter equal to discharging tube diameter of condenser and outlet diameter equal to inlet diameter of expansion valve. Additional pressure drop in the nozzle helped to achieve higher performance of the vapour compression refrigeration system. The system is analyzes using the first and second laws of thermodynamics, to determine the refrigerating effect, the compressor work input, coefficient of performance (COP).
