Re: M.E.S Question Papers for Refrigeration and Air-Conditioning
Ok, as you want the question paper of Refrigeration and Air-Conditioning so here I am providing you. Refrigeration and Air-Conditioning question paper 1.The condensing pressure due to the presence of non condemnable gases, as compared to that actually required for condensing temperatures without non condemnable gases, will be higher will be lower will remain unaffected may be higher or lower depending upon the nature of non condemnable gases unpredictable. 2.The moisture in a refrigerant is removed by evaporator safety relief valve dehumidifier driers expansion valve 3.Ammonia-absorption refrigeration cycle requires very little work input maximum work input nearly same work input as for vapour compression cycle zero work input none of the above. 4.In vapour compression cycle, the condition of refrigerant is high pressure saturated liquid after passing through the condenser before passing through the condenser after passing through the expansion or throttle valve before entering the expansion valve before entering the compressor. 5.In vapour compression cycle, the condition of refrigerant is very wet vapour after passing through the condenser before passing through the condenser after passing through the expansion or throttle valve before entering the expansion valve before entering the compressor. 6.Critical temperature is' the temperature above which a gas will never liquefy a gas will immediately liquefy water will evaporate water will never evaporate none of the above. 7.Clapeyron equation is a relation between temperature, pressure and enthalpy specific volume and enthalpy temperature and enthalpy temperature, pressure, and specific volume temperature, pressure, specific value and enthalpy. 8.A standard ice point temperature corresponds to the temperature of water at 0�C ice at - 4�C solid and dry ice mixture of ice, water and vapour under equilibrium conditions under NTP conditions mixture of ice and water Under equilibrium conditions. 9.In S.J. unit, one ton of refrigeration is equal to 210 kJ/min 21 kJ/min 420 kJ/min 840 kJ/min 105 kJ/min. 10.One ton of refrigeration is equal to the refrigeration effect corresponding to melting of 1000 kg of ice in 1 hour in 1 minute in 24 hours in 12 hours in 10 hours. 11.In vapour compression cycle the condition of refrigerant is superheated vapour after passing through the condenser before passing through the condenser after passing through the expansion or throttle valve before [entering the expansion valve before entering the compressor. 12.The boiling point of ammonia is -100�C -50�C - 33.3�C 0�C 33.3�C. 13.Clapeyron equation is applicable for registration at saturation point of vapour saturation point of liquid sublimation temperature triple point critical point. 14.In vapour compression cycle the condition off refrigerant is dry saturated vapour after passing through the condenser before passing through the condenser after passing through the expansion or throttle valve before entering the expansion valve before entering the compressor.. 15.The vapour compression refrigerator employs the following cycle Rankine Carnot Reversed Rankine Brayton Reversed Carnot. |
