1. A five-star hotel needs hot water on a 24/7 basis at 60 C (assume inlet at 60 and outlet at 50 C). The estimated total load is 2500 kW (th). Design a heat pump system using any refrigerant which has low GWP and is zero Ozone depleting characteristics. Look up to the tables and select anyone. R 134 a, R22 or any other fluids. Electrical Energy 2500 kW (th) @ 60 C inlet and outlet at 50 C Sink available at 32 C as cooling water- or air-cooled system. Calculate the electrical energy needed to meet the above requirements.
