A cascade system with one refrigeration cycle operating with R-410a has an evaporator. Find the ratio of the two cycle's mass flow rates and the overall COP.
For this project, complete an economic analysis of the firm you selected. Include the following: Behavior of the firm and the industry.
Determine the entropy generation in the compression process, the refrigeration capacity, and the COP for this cycle.
Determine the amount of energy saved by using the heat pump instead of directly heating the water from 15oC to 60oC.
Find the power input to the compressor and the rate of entropy generation in the compressor process.
A refrigerator in a laboratory uses R-134a as the working substance. Find the cycle COP and the electrical power required.
What is the mass flow rate of the R-134a, and what is the low-temperature heat transfer rate? What is the mass flow rate of air at 10oC?
After the compressor, the temperature is measured to be 60oC. Find the actual compressor work and the actual cycle COP.
