Required information Problem 12.019 - Actual refrigeration cycle A refrigerator uses refrigerant-134a as the working fluid and operates on the vapor-compression refrigeration cycle. The evaporator and condenser pressures are 140 kPa and 1400 kPa, respectively. The isentropic efficiency of the compressor is 88 percent. The refrigerant enters the compressor at a rate of 0.024 \( \mathrm{kg} / \mathrm{s} \) superheated by \( 18.77^{\circ} \mathrm{C} \) and leaves the condenser subcooled by \( 4.4^{\circ} \mathrm{C} \). Problem 12.019.a - Rate of heat removal from the refrigerated space Determine the rate of heat removal from the refrigerated space, the rate of heat rejection from the refrigerant to the environment, the power input, and the COP. (Take the required values from saturated refrigerant-134a tables.) (Round the final answers to three decimal places.) The rate of heat removal from the refrigerated space is The rate of heat rejection from the refrigerant to the environment is kW . The power input is kW . The COP is
