A dehumidifier receives a flow of 025 kgs dry air at 28°C, 80% relative humidity, as shown in the figure. It is cooled down to 20°C as it flows over the evaporator and then is heated up again as it flows over the condenser. The standard refrigeration cycle uses R-22 with an evaporator temperature of5°C and a condensation pressure of 1600 kPa. Determine: (a) the amount of liquid water removed, (10 points) (b) the heat transfer in the cooling process,...
Thermodynamics A two-stage vapour-compression refrigeration plant shown in Figure Q2 diagrammatically below is discharged with Refrigerant 12. Both compressors are single-acting, single-stage reciprocating machines with four cylinders and as isentropic efficiency of 80%. They each have a stroke/bore ratio of 1.2 and run at 600 rev/min with a volumetric efficiency of 90%. The condenser, flash chamber and evaporator pressures are 10 bar, 3 bar and 1 bar respectively. Saturation states exist at points 5 and 3 and the vapour at...
Problem 2: A residential air-conditioner with an actual cooling capacity of 14.06 kJ/s (4 tons), cools and dehumidifies a steady stream of air flowing over the cooling coil. Actual states for the Refrigerant 134a are given Notice that the compressor efficiency is less than 100% and there are small pressure drops given for the heat exchangers. The coefficient of performance is 3.51 for the actual cycle. Changes in kinetic and potential energy are negligible. The warm indoor air temperature entering...

summatize the following info and break them into differeng key points. write them in yojr own words apartus 6.1 Introduction—The design of a successful hot box appa- ratus is influenced by many factors. Before beginning the design of an apparatus meeting this standard, the designer shall review the discussion on the limitations and accuracy, Section 13, discussions of the energy flows in a hot box, Annex A2, the metering box wall loss flow, Annex A3, and flanking loss, Annex...
