A gas refrigeration system using air as the working fluid has a pressure ratio of 5 . Air enters the compressor at 0^∘ C. The high-pressure air is cooled to 35^∘ C by rejecting heat to the surroundings. The refrigerant leaves the turbine at -80^∘ C and then it absorbs heat from the refrigerated space before entering the regenerator. The mass flow rate of air is 0.4 kg / s . Assuming isentropic efficiencies of 80 percent for the compressor and 85 percent for the turbine and using constant specifi

An ideal gas refrigeration system with two stages of compression with intercooling as shown in Fig. P 11-77 operates with air entering the first compressor at 90 kPa and -24^∘ C . Each compression stage has a pressure ratio of 3 and the two intercoolers can cool the air to 5^∘ C. Calculate the coefficient of performance of this system and the rate at which air must be circulated through this system to service a 45,000 kJ / h cooling load. Use constant specific heats at room temperature. | Numera

An ideal vapor-compression refrigeration system operates at steady state with Refrigerant 134a as the working fluid. Superheated vapor enters the compressor at 30 lbf / in . ^2, 20^∘ F, and saturated liquid leaves the condenser at 140 lbf / in . ^2 The refrigeration capacity is 5 tons. Determine (a) the compressor power, in horsepower. (b) the rate of heat transfer from the working fluid passing through the condenser, in Btu / min. (c) the coefficient of performance. | Numerade

A gas refrigeration system using air as the working fluid has a pressure ratio of 5 . Air enters the compressor at 0^∘ C . The high-pressure air is cooled to 35^∘ C by rejecting heat to the surroundings. The refrigerant leaves the turbine at -80^∘ C and enters the refrigerated space where it absorbs heat before entering the regenerator. The mass flow rate of air is 0.4 kg / s.

An ideal gas refrigeration system operates with air as the working fluid. Air is at 100 kPa and 20^∘ C before compression and 500 kPa and 30^∘ C before expansion. The system is to provide 15 kW of cooling. Calculate the rate at which air is circulated in this system, as well as the rates of heat addition and rejection. Use constant specific heats at room temperature. | Numerade
