Give the Energy balance at an open heater

The coefficient of performance (COP) for a vapor compression cycle chiller is 8.  If the chiller can produce 46 tons of cooling, how much electric power (in kW) does the chiller consume? Fill in the electric power of the chiller in kW.

Work is done on a system in (mark all): a) Refrigeration cycle b) Power cycle c) Heat pump cycle

9) What is the refrigeration effect?A: It is the energy transfer per kg of refrigerantB: It is the energy transfer per oC of refrigerantC: It is the energy reject per kg of refrigerantD: It is the energy reject per oC of refrigerant
