A Customs Station refrigeration chamber has an installed capacity of 250TR for refrigeration of cargo destined for export. This chamber operates with refrigerant (R-423A) between temperatures of 60C and 10C. The refrigeration cycle has a stage one understanding where at the compressor inlet the refrigerant vapor is superheated by 10C and compression is ideal. For these cycle operating conditions, determine: A. The volumetric flow rate (under compressor inlet conditions) of the refrigerant; B. The power of the compressor; C. The amount of heat delivered to the hot source D. The COP (Coefficient of Performance)
