A chiller tank with a water volume capacity of 20 M3. There are 2 chiller units with a capacity of 20 PK each to cool the water in the chiller tub. 1 unit of cold chiller water transfer pump is used to the production area with a capacity of 5 M3/hour. The chiller water temperature sent to production is 15 oC and the pressure is 4 bar. The distance of the 2 inch stainless pipe from the chiller pump to the double jacket mixing tank production is 100 meters. The diameter of the inlet and outlet pipes for the double jacket mixing tank is 1 inch. The chiller water storage capacity in a conventional double jacket mixing tank is 400 liters. (mixing tank capacity is 1500 kg). Questions: 1. How much time is needed to cool the water in the mixing tank from the initial temperature of 90 oC to 40 oC? 2. How much energy (BTU) is needed to cool the water temperature from 90 oC to 40 oC? 3. How much energy is lost along the 100 meters of chiller water transfer pipe? 4. If the number of 1500 Kg…
select if true or false for the following questions 1. For a standard condenser in a refrigeration system, the thermal energy (in J) is equal to the mass (in kg) multiplied by the change in enthalpy across the condenser (in J/kg). 2. Consider a basic refrigeration cycle: Since it requires less work to compress a liquid than a vapor, the entire refrigeration process would work better if the compressor was replaced with a pump. All else being equal, increasing the mass-flow rate of refrigerant will increase the rate of heat transfer at the system’s evaporator. All of these (except, of course, the one labeled, “None of these.”) None of these.

Q.1. A refrigeration process with interstage cooling uses refrigerant HFC-134a, and the outlet of the condenser is to be saturated liquid at 40°C. Refer to the following figure for stream numbers in your solution. The pressure of the flash chamber and the intermediate pressure between compressors is to be 290 kPa. The evaporator is to operate at -20°C and the outlet is to be saturated vapor. The flowrate of stream 1 is 23 kg/h. The flash chamber may be considered adiabatic.
