Draw the Ts/Ph Diagram A 50-ton vapor compression refrigeration system is to evaporate R-12 at -20°C and to condense it at 40°C. The vertical compressor is to run at 10000 rpm; it is double acting, has the bore equal to the stroke, and has 10% clearance. Vapor enters the compressor at -10°C and liquid enters the expansion valve at 30°C. What refrigeration flow rate is required? What would be the bore and stroke of the compressor? What power is required by the compressor? What is the quantity of the cooling water required in the condenser for a 8-degree increase in temperature?
The figure below shows a two-stage vapor-compression refrigeration system with ammonia as the working fluid. The system uses a direct-contact heat exchanger to achieve intercooling. The evaporator has a refrigerating capacity of 40 tons and produces -30°F saturated vapor at its exit. In the first compressor stage, the refrigerant is compressed adiabatically to 140 lbf/in.², which is the pressure in the direct contact heat exchanger. Saturated vapor at 140 lbf/in.² enters the second compressor stage and is compressed adiabatically to 250 lbf/in.² Each compressor stage has an isentropic efficiency of 85%. There are no significant pressure drops as the refrigerant passes through the heat exchangers. Saturated liquid enters each expansion valve. Determine: Expansion valve 6- Condenser Direct contact heat exchanger Expansion valve (a) the ratio of mass flow rates, m3/my. (b) the power input to each compressor stage, in horsepower.

4. A refrigerating plant having R-12 as the working fluid, comprises three evaporators of 10 TR at -10°C, 20 TR at 5°C and 30 TR at 10°C. Each of the evaporators is having the individual expansion valve arrangement. The refrigerant from the higher stage expansion valve is bled and mixed with delivery from the lower stage compressor and sent to the higher stage compressor suction thus effecting intercooling of the delivery gas from the lower stage and bringing the suction of the higher stage compressor to dry and saturated conditions. There is only one condenser operating at 40°C and sub- cooling the liquid refrigerant to 30°C. The compression during each stage of compression may be assumed isentropic. The evaporator discharge is dry saturated in cach of the evaporators. Determine the power required by the entire system. 5.
