WebJan 22, 2024 · direct and indirect impact on the greenhouse effect. 1. INTRODUCTION . The environmental impact of a refrigeration equipment depends on the refrigerant losses (direct effect) and on the energy consumption (indirect effect) during the whole lifetime of the system. The recent European F-gas regulation WebThe refrigeration effect can be achieved by using one of these cycles: • Vapor compression-expansion • Absorption • Steam jet (water-vapor compression) By using the pressure–enthalpy (P-H) diagram, the refrigeration cycle can be broken down into four distinct steps: 1. Expansion 2. Evaporation 3. Compression 4. Condensation

WebMar 6, 2024 · The refrigeration effect at low load is 72 Btu/pound. Multiply by the flow, 2.46, and the system capacity is 177 Btu/minute. As stated earlier, the system needs to operate at half load, or 6000 Btu/hour = 100 Btu/minute. We need to apply 77 Btu/min (177 – 100) of hot gas bypass to reduce the amount of liquid available for refrigerating with ...
