Assignment Help Mechanical Engineering
Reference no: EM13906808

A large refrigeration plant is to be maintained at -15C, and it requires refrigeration at a rate of 100kW. The condenser of the plant is to be cooled by liquid water, which experiences a temperature rise of 8C as it flows over the coils of the condenser. Assuming the plant operates on the ideal vapor-compression cycle using refrigerant 134-a between the pressure limits of 120 and 700 kPa, determine

1. The mass flow rate of refrigerant

2. The power input to the compressor

3. The mass flow rate of the cooling water

Show the cycle on T-s diagram and state ALL assumptions and proper units.
