WebbHowden Optimise our customers’ air and gas handling processes WebbAn ammonia refrigeration plant operates between 2.265 bar and 10.34 bar. The ammonia leaves the evaporator at −10°C and leaves the condenser as a liquid at 26°C. The refrigerant mass flow rate is 0.4 kg/min and the compressor power requirement is 1.95 kW. Calculate: (a) the dryness fraction at the evaporator inlet; (b) the cooling load; (c)
WebbTemperature. Equilibrium considerationsLe Chatelier's Principle, this will be favored if you lower the temperature. The system will respond by moving the position of equilibrium to counteract this - in other words by producing more heat. To get as much ammonia as possible in the equilibrium mixture, you need as low a temperature as possible ... WebbAmmonia, if present in the ice shells of icy satellites, could lower the temperature for the onset of melting to 176 K and create a large temperature range where partial melt is …
