[0002] Internet cafes are typical public commercial venues, with the main energy consumers being air conditioning and computers. An analysis of internet cafes with 80-100 computer seats reveals an average annual energy consumption of approximately 120,000-150,000 kWh, of which air conditioning accounts for approximately 70%, resulting in an average annual energy consumption of 84,000-105,000 kWh. Due to the high commercial electricity price of 1.2 yuan per kWh, the average annual air conditioning electricity bill for an internet cafe is approximately 100,000-126,000 yuan. Energy conservation in internet cafe air conditioning systems is crucial for reducing costs and increasing efficiency.
