Question 1: An air cooling system is to be used to cool a storage facility. The facility is to be maintained at 10°C at all times. It is estimated that the facility is absorbing heat at a rate of 100 MJ/hr when the outside temperature is 35°C. a. Draw the system that includes the facility and a cooling unit. b. Write the energy balance for the storage facility and determine Wnet, Qn and Qout- c. Under this condition, determine the minimum power required to drive the cooling system and calculate cooling capacity (ton of refrigeration) and SEER rating. d. What is an additional information that you need in order to calculate the actual power required? Give an example of calculation.
