An inverter air conditioner with a rated power of 220V 3000W was used to cool down the flat in summer and warm it up in winter. The COP during cooling is 3.1. What is the COP of the AC during heating? (1 marks) Find the rated current of the AC. (1 marks) If the electricity supply of the building malfunctions and the voltage drops to 165V, what is the power consumption of the AC now? (2 marks) Hence, what is the cooling capacity of the AC? Assume the COP does not change. (1 marks) An inverter air conditioner with a rated power of 220V 3000W was used to cool down the flat in summer and warm it up in winter.
