Final answer:
The solution to determine the rate of heat absorbed from the air and the change in air temperature in a refrigeration cycle involves thermo-dynamic calculations using specific enthalpy values that cannot be provided without further data or tools.
Step-by-step explanation:
The question requires an understanding of the principles of thermodynamics as they relate to the operation of refrigeration cycles and heat transfer. To determine the rate of heat absorbed from the air by the evaporator when refrigerant-134a is used, we need to calculate the specific enthalpies at both the inlet and outlet of the evaporator using the refrigerant's pressure and temperature properties, and then apply the mass flow rate of the refrigerant. However, since we are missing the specific enthalpy values and the capacity to calculate them here, we cannot provide the quantitative answer for the heat transfer rate.
The change of temperature of air can be found by using the principle of conservation of energy, where the heat lost by the air is equal to the heat gained by the refrigerant. We would use the specific heat capacity of air and the mass flow rate given to find the temperature change. This calculation, too, is dependent on the initial determination of the rate of heat absorbed by the refrigerant, which we do not have the data to calculate here.
Without the required thermodynamic property tables or a software package that provides these details for Refrigerant-134a, solving for the missing values is not feasible in this response.
