Refrigeration interstage theory
WebThe saturated gas refrigerant enters the interstage mixing chamber of the compressor through the vapor injection port, and the saturated liquid refrigerant enters the evaporator after being throttled and depressurized by the second-step electronic expansion valve. WebRefrigeration compressors are multisectional machines with sideloads or extractions depending on the process design . Mismatches of the head required per section and large swings in flowrates (between design and …

WebJun 1, 2001 · The most common design has three stages for pressures in the 100-150-psig range. Designs with 8 stages can reach pressures up to 1200 psig. A water-cooled intercooler and separator between stages return the air temperature to approximately ambient and remove condensed moisture. WebA refrigeration process with interstage cooling uses refrigerant R134a. The outlet of the condenser is to be saturated liquid at 40 o C. The evaporator is to operate at -20 o C and the outlet is saturated vapor. The economizer is to operate at 10 o C. Refer to Fig 5.10 (textbook) for stream numbers in your solution.
WebFeb 7, 2024 · The cold refrigerant enters the evaporator and passes on the inside of some pipes inside the evaporator and a fan blows the warm room air across the outside of these tubes. The cold refrigerant absorbs this … WebIn usual AC condenser, gas refrigerant is cooled by air flow. The heat transfer coefficient is small for the gas phase. In SLIM, gas refrigerant is cooled by cooling water, thereby, improving heat transfer coefficient. A small water-cooled condenser is attached in the tank of a sub-radiator.
