WebThese diagrams can be found in the ASHRAE Fundamentals book. A sample R-134a diagram is shown below, with a sample refrigeration cycle, identifying (Step 1) Evaporator, (Step 2) Compressor, (Step 3) Condenser and (Step 4) Expansion Device. STEP 1: EVAPORATOR. The refrigerant entering the evaporator is a cold, partial liquid-vapor mixture. WebDec 11, 2024 · An air refrigeration system works on Bell – Coleman cycle. It draws air at the rate of 1 kg/s from the cold chamber at 1 bar and 5° C. Air is compressed to 7 bar and then is cooled to 25°C before sending it to expansion cylinder. Given γ = 1.4 c p = 1.005 kJ/kg-K and 7 0.286 = 1.745. Refrigeration effect for this system in tonne per hour, is:
