Web1. Consider a two-stage cascade refrigeration system operating between the pressure limits of 1.2 MPa and 200 kPa with refrigerant-134a as the working fluid. Heat rejection from the lower to the upper cycle takes place in a countercurrent adiabatic heat exchanger where the pressures in the upper and lower cycles are 0.4 and 0.5 MPa, respectively. WebSo, the refrigerant condensing temperature is normally designed at around 120°F (49°C). Based on the refrigerant temperature, we can see from the PH diagram that the corresponding refrigeration pressure is around 420 psi and this is the typical discharge pressure (discharge line) of an R410A air conditioner. old school vans high tops https://b-vibe.com

WebAmmonia changes state from liquid to gas in the evaporator (1) producing the refrigeration capacity at a temperature from a few degrees down to – 60 deg C. The natural tendency of water to absorb ammonia permits it to collect the ammonia vapor by the weak solution in the absorber (2). This absorption of ammonia vapor in water is exothermic. WebDec 20, 2011 · The savings, while not as dramatic as the two-stage versus one-stage, can still be significant enough to justify the additional equipment (GPSA, 1998).
