Problem 3 An air-cooled condenser is to reject 70 kW of refrigerant to air. The condenser has an air-side area of 210 m² and a U value based on this area of 0.037 kW/m²-K; it is supplied with 6.6 m³/s of air which has a density of 1.15 kg/m³. If the condensing temperature is to be limited to 55°C, what is the maximum allowable temperature of the inlet air? heat from condensing a th = constant O(= th – te) 1 2
