Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Refrigerant-134a enters the condenser of a residential heat pump at 800 kPa and 50°C at a rate of 0.024 kg/s and leaves at 750 kPa subcooled by 3°C. The refrigerant enters the compressor at 200 kPa superheated by 4°C. (Take the required values from saturated refrigerant-134a tables.) Он 750 kPa Condenser Expansion valve Evaporator ė 800 kPa 50°C Compressor Determine the rate of heat supplied to the heated room. (You must provide an answer before moving to the next part.) The rate of heat supplied to the heated room is kW.
